NEET BIOLOGY

Detailed explanation-1: -The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

Detailed explanation-2: -The lungs are responsible for the excretion of gaseous wastes, primarily carbon dioxide from cellular respiration in cells throughout the body. Exhaled air also contains water vapor and trace levels of some other waste gases.

Detailed explanation-3: -Lungs. Our lungs are mainly concerned with respiration, but they help in the removal of a large amount of carbon dioxide and water from our body through the air that we expire. Carbon dioxide is a waste product formed due to the oxidation of food. It is carried to the lungs by the blood.

Detailed explanation-4: -Lungs. Lungs facilitate gaseous exchange. They help in inhaling oxygen and eliminating carbon dioxide and water vapour from the body.

Detailed explanation-5: -CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation.
