How are cardiovascular and respiratory system related?

Answer 1

The cardiovascular and the respiratory system both work toward the same goal: getting oxygen to tissues and getting carbon dioxide out. The respiratory system is involved in supplying oxygen to the blood and removing carbon dioxide. When the heart receives blood that is low in oxygen and high in carbon dioxide, it pumps it to the lungs via the pulmonary arteries. When the lungs expand and get fresh air from the environment, oxygen is transferred (via the alveoli) into the low-oxygen blood, which also then sends some of its carbon dioxide back into the lungs. Now that this blood has fresh oxygen in it, it returns to the heart and the heart then pumps it throughout the body.

Answer 2

The respiratory system allows for gaseous exchange. Gaseous exchange involves trading carbon dioxide that your body cells produce for oxygen that is in the atmosphere.

Your body needs oxygen in order to get energy from the food that you eat. When you eat carbohydrates and other foods, your body "burns" the food molecules using the oxygen, and that creates energy, carbon dioxide, and water. The energy allows body cells to do what they do, depending on what the cell's job is. It is needed for the cells to grow, to replicate, to make and release hormones and chemicals needed by the body, and all sorts of other things. It's needed by muscles to contract and relax, it's needed by nerves to send signals around your body. Without energy, you're pretty much screwed.

So the respiratory system provides your body cells with the oxygen that it needs to convert food molecules into energy. But what it also does is that it transports carbon dioxide out of your body. Carbon dioxide is a waste product from the above reaction, and without the respiratory system to let it all out, it would accumulate and turn into carbonic acid, which would eventually kill you.

So to conclude, your respiratory system supplies oxygen (using the blood stream) to all the other systems to allow them to obtain energy from food molecules, and gets rid of the harmful carbon dioxide that is produced.

Answer 3

Oxygen is needed in the bloodstream, so when the blood that is being pumped by the cardiovascular system lacks oxygen, it is sent to the lungs to become oxygenated. Also, once the blood is oxygen, there are specific blood vessels that take the oxygenated blood back to the heart to be transported throughout the body.

Answer 4

The Respiratory and Cardiovascular systems work together to supply oxygen to the cells, to remove Carbon Dioxide, and to regulate the pH of the body fluids.
