Answer:
1. The heart and lungs work together to make sure the body has the oxygen-rich blood it needs to function properly. The Pulmonary Loop The right side of the heart picks up the oxygen-poor blood from the body and moves it to the lungs for cleaning and re-oxygenating.
2. Blood brings oxygen and nutrients to all the parts of the body so they can keep working. Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body. Blood also fights infections, and carries hormones around the body.
3.Our body needs oxygen to obtain energy to fuel all our living processes. Carbon dioxide is a waste product of that process. The respiratory system, with its conduction and respiratory zones, brings air from the environment to the lungs and facilitates gas exchange both in the lungs and within the cells.
4.Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled. ... Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide
