Respiratory vs. Circulatory



Alright, so you know that both of these systems are super important in our bodies. We obviously need air, or oxygen, to survive and our body needs blood to keep our heart pumping too. There any many similarities amongst the systems in our bodies. Some of the parts of these systems do almost the same job, just in a slightly different way. Can you make any connections between the respiratory system and the circulatory system? How do they, if at all, interact with each other? How are they similar or different? If you really want to take it a step further, see if you can compare it with the digestive system, cell respiration and/or photosynthesis too! This will require complete and detailed sentences so that we all can understand the connection you are trying to make. Be sure to proofread!! (Use the "teacher's eye"!!)

I have a connection for the respiratory and the circulatory system. The respiratory system ends at the air sacs, while the circulatory system starts with the air sacs. I didn't find an interaction that I could use.

The Respiratory system move oxygen to the air sacs and the circulatory system picks up the oxygen. Half of the Respiratory system is involuntary and the Circulatory system is all voluntary. The Respiratory system ties in with the Digestive System because the esophagus splits into two tubes: esophagus and trachea. The air sacs are similar to the villi-it chooses what it wants and what it doesn't want.

I agree with you Richard about the connection you made with the digestive system and about the transfer of gases at the air sacs. But....how is half of the respiratory and all of the circulatory voluntary? Doesn't voluntary mean that YOU control it? Also, I love the connection you made with air sacs and villi. They both send out items into the bloodstream through tiny capillaries. But...the air sacs take in a material, do the villi?

The Respiratory system and the circulartory system both have a trading post that tie in. The mouth/nose of the Respiratory system brings in the oxegon and lets out carbon dioxide when the air sacs also bring in oxegon in and carbon dioxide out but for a different reason, which is to pump the blood that our bodies need.
The Respiratory system is also simular to photosynthesis because the carbon dioxide gets taken in and the oxegon goes out but in the respiratory system, the oxegon gets taken in and the carbon dioxide goes out.

It sounds very interesting because I wonder how it looks in your body in real life. They are both important because it has to do with the Respiratory system and ties in with the Digestive system as well. I am also glad we have them in our body because then if we didn't we would be dead. Also, the air sacs are similar to the villi too.

Chrissy said...

Don't forget to include the "why?"!!! You must explain your thinking and have a reason behind it!

I think that the respiratory system is like the digestive system. The villi in the small intestine collects food and releases into the bloodstream. The air sacs in the lungs release oxygen to the blood cells instead of food. Without those two parts, we would not be able to live very long.

Both the respiratory and circulatory relay on each other.If you have oxygen {from the respiratory system}then only can you have blood {from the circulatory system}.Blood needs oxeygn ,so it can be healthy and waste can go out the repiratory system.The air comes in from our respiratory system.We can't live without our respiratory system.

A connection with the respiratory system and the circulatory system would be that both are essentials in the body and you can't have a heart and the circulatory system without the lungs which give the blood oxygen and you can't have lungs without the blood because then where does the oxygen go? Also both systems are involuntary because you don't have to think about your heart to pump and you don't have to think about breathing for your lungs to take in oxygen. Now, if you had to think about breathing and if you have to think about pumping your heart wouldn't that be hard?

The Air Sacs in the Respiratory System put the oxygen into the red blood cells and they go to the left side of the heart(which is in the Circulatory System).Then they go throughout the body.The red blood cells give oxygen to the cells. The cells take the oxygen for cell respiration and give out CO2. Finally,the red blood cells go back to the Air Sacs,exchange CO2 for oxygen,and start the whole process again.

I think that they are both important because they use each other. The blood cells take the oxygen you breathe and gives the lungs the CO2 so the lungs exhale it. The blood cells then go around the body and gives its oxygen to the places that need it. The blood cells then go back to the lungs to get air and give out CO2. The heart pumps the blood cells through the arteries and veins. The blood cells with oxygen go through the left side of the heart right after getting oxygen from th lungs. The bad CO2 blood cells go through the right side of the heart to go to the lungs to get oxygen. This how the respiratory system and the Circulatory system work together. BYE!!!

The respiratory and circulatory systems are very similar because the trachea is like the esophagus, but food moves down the esophagus and air moves down the trachea. Also, our lungs are like the stomach; they hold air, the stomach holds food.

This post teaches me of how important it is to have a heart.A connection between the respiratory system and the circulatory system is that we need both systems to live. They are different because the circulatory system pumps blood, but the respiratory system helps you breathe and gets air for your lungs, which has air tubes leading to air sacks. The lungs pump air to the air sacks which makes red, healthy blood and the heart pumps the healthy blood to different parts of the body which includes the digestive system too.

I think that the Respiratory System and the Circulatory system are important like Matt said, I don't what we would with out them!It's like a relay race, the respiratory system goes uptil the air sacs and finishes its turn now it's the ciculatory system's turn.

One connection that I have about the Respiratory and the Circulatory systems is:
*The Respiratory carries oxygen into the air sacs and the air sacs take the oxygen and put it in the red blood cells that pass it to the heart throught the blood vessel. The blood vessels carry the blood with the oxygen and drop it off at the left side of the heart and at the same time the carbon dioxide (from the cell respiration) filled red blood cells are going back to the air sacs by the blood vessels (this happens on the right side of the heart). Now you are able to breathe out once the carbon dioxide reaches the air sacs (which happens really fast). This continues over and over agian. The heart and the blood and the blood vessels are apart of the Circulartory System and the air sacs and lungs are apart of the Respiratory System.

They both connect in the blood where the oxygen comes in. That's how they interact with eachother (they do interact). They can also connect with the Digestive System, Cell Respiration and Photosynthesis:
*After you eat food you need Cell Respiration to make the energy you need to move, be active and grow. Cell Respiration breaks down the food to carbon dioxide (CO2) and water (H2O). With photosynthesis (whichs happens in the plant)the plant makes food out of water sunlight and carbon dioxide. Photosynthesis mixes them together and makes the plant's food. Cell Respiration breaks down the food and seperates it into CO2 and water(like it does to your body). We, humans, have Cell Respiration as well as plants. Photosynthesis is the making of food for plants and we get our food by EATING THROUGH OUR MOUTHS, NOTSUCKING IT IN THROUGH OUR ARMS BY SPREADING THEM OUT AND 10 SECONDS LATER WE SAY WE ARE FULL!!!! This is how I connect Cell Repiration, Photosynthesis, the Digestive System, the Respiratory System, and the Circulatory System.

Chrissy said...

Meryem, fabulous detailed answer! You fully explained so many connections.

The Respiratory and Circulatory systems are both important. Without the respiratory system then the oxygen we need will not get into our bodies and CO2 from our bodies have no where to get out. Also, without the Circulatory System, the oxygen will not be able to reach the cells which need it. The Respiratory system and the photosynthesis are opposite. The respiratory system helps us inhale O2 and exhale CO2. However, photosynthesis needs CO2 to generate O2. Therefore, plants and animal are trading what they need.

the Respiratory system moves oxygen to the air sacs and the circulatory system picks up the oxygen. Both the systems are involuntary.Both systems require blood and oxygen.

The Respiratory and Circulatory system are both important because you need the Respiratory system to move the oxygen we need. We need the Circulatory System, or else the oxygen will not be able to reach the cells who need it. The Respiratory system and the Circulatory system work together in order to get the oxygen to the air sacs. Without both systems we would die.

Well I think they are both pretty important because we coudn't live if we didn't have either.The Alveoli give air to the blood so they work together when they are exchanging gases. Well the waste product of cell respiration is Co2 and the exchange of gases is between Co2 and o2. You exhale Co2 too.

The respiratory system and the circulatory system both have to do with air because the respiratory system brings air in and out of your body. The circulatory system kind of helps with the respiratory system because the capillaries are around the air sacs which kind of makes a little path for blood cells to drop off CO2 and gain O2.

Anonymous said...

One connection between the two is that the respiratory system sends the oxygen to the air sacs and the the circulatory system picks up the oxygen. They interact because the circulatory system is all involuntary and the respiratory system is half voluntary.

There are two connections that I have between the the respiratory system and circulatory system. The respiratory system laeves the oxygen at the air sacs. Then the circulatory system picks it up. As Joanna said "Without both systems you die." Both of them are important to your body.

It's sort of like a chain reaction. The respiratory system ends at the air sacs and the circulatory system stars at the air sac. If we didn't have the respiratory system, the circulatory system probably can't work. It's like they sort of depend on each other. Also,the respiratory and circulatory system are like trading posts. When the blood cell is filled with oxygen, it shares it all throughout the body system. Once it turns blue, it swaps its CO2 with the oxygen. Isn't it interesting?

One connection I have between respiratory system and the digestive system is that the villi and air sacs do the same thing,they let the waste come out of your body.They are similar because they both use involuntary muscles.They are different because the respiratory system gives you oxygen and the circulatory system pumps blood to your whole body.Photosynthesis in plants is similar but here CO2 is taken in for making glucose and O2 is the waste product.

The respiratory and the circulatory system are connected because, like Richard said, the respitory system's main purpose is to give oxygen to the air sacs so that the cells in the capillaries can distribute it to the body and the air sacs can take the waste product of cell respiration, carbon dioxide from the cells to exhale it out of our body.
The digestive system is also related to the respiratory system because the esophagus (the tube that brings down the food to the stomach) splits into the trachea or the wind pipe. Also, like Richard said, the air sacs are similar to the villi because they have to choose the right air or food (by then tiny mush).
One way, like Jamie said, the respiratory system is similar to photosynthesis is that carbon dioxide gets out and oxygen comes in in the respiratory system but in photosynthesis it is the other way around.
Basically, the entire body is an amazing system dependent on every other part.

The respiratory system and the circulatory system are important because without them we cannot live. The respiratory system and the circulatory system are similar because the circulatory system has to pick up the oxygen the respiratory system sent to the cells. The respiratory and circulatory system are very involuntary. The digestive system does tie in with the respiratory system because of the villi and air sacs. The air sacs and villi chooses what it wants and what it doesn't want. These are some reasons why the circulatory system and the respiratory system are similar.

I agree with Richard and with Ms.Mcpheeters. The respiratory system and digestive system are the same.And the circulatory system are quite alike. I agree with Ms.Mcpheeters to, because how can you control half of your respiratory system?I think they are the same because like what Olivia said, they both end in air sacks.

The Respiratory and Circulatory system are alike because they help your body make food. The Respiratory system gives blood the oxygen for the red blood cells to carry to the cells in the body. The RBC filled with O2 can't just go to the cells in the body so it needs to go back to the heart to get pumped there.

The Respiratory system is alike to the Digestive system because they both give the cells something that helps them either turn them from blue blood cells to RBC or nutrients to repair them. The Digestive system gives them nutrients from broken down food. the Respiratory system gives them O2 to turn it red.

The digestive system is alike to Cell Respiration because they both break down food. The only differences about this is that the size of the food is different and there are many more steps in the Digestive system.

The Respiratory system is alike to Photosynthesis because they both release waste gases in the process. Photosynthesis releases O2(which we need(and the Respiratory system releases CO2(which plants need) so basically we release the gas they need and they release the gas we need so if one of us went extinct then the other on would probably be wiped out because of the wrong type of air particles.
