How do the lungs excrete waste material from the body? the lungs push carbon dioxide from red blood cells out of the body through exhalation. the lungs convert poisonous gas into oxygen that the body can use. the lungs push nitrogen into the digestive system so that it can be removed by the body. the lungs protective cells in the body break down gaseous urea.

A. The lungs push carbon dioxide from red blood cells out of the body through exhalation.

The lungs push carbon dioxide from red blood cells out of the body through exhalation.

Explanation:

A cellular respiration is a metabolic process that occurs in the living organisms. This involves the exchange of gases (oxygen and carbon dioxide) between the body and the surrounding environment. The oxygen is the main requirement for the body for cellular metabolism it is inhaled and circulated by combining with the heme group of red blood cells. The carbon dioxide is the gas which is not required by the body it is exhaled by the lungs which was transferred by all cells of the body to the lungs.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
