what is a respiratory system?
Answers
Answer:
The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history
Answer:
The respiratory system, also called the gas exchange system, is the body getting rid of carbon dioxide and taking in oxygen. Carbon dioxide, a waste product, goes out of the body.Inhalation means bringing air rich in oxygen into the body. Exhalation means giving out air rich in carbon dioxide from the body.
Your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood.
