Answer 1

The respiratory system is responsible for bringing oxygen into the body and removing carbon dioxide, which is a waste product of metabolism. This system includes the nose, lungs, and airways, and it works closely with the circulatory system. When we breathe in, oxygen goes into the lungs and then enters the bloodstream, where the circulatory system transports it to cells throughout the body. At the same time, carbon dioxide is carried back to the lungs by the blood, where it is expelled when we exhale. This cooperation between the respiratory and circulatory systems is vital for maintaining homeostasis, as our body needs a stable supply of oxygen to function properly.
