THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -At each cell in your body, oxygen is exchanged for a waste gas called carbon dioxide. Your bloodstream then carries this waste gas back to the lungs where it is removed from the bloodstream and then exhaled. Your lungs and respiratory system automatically perform this vital process, called gas exchange.

Detailed explanation-2: -The lungs in the respiratory system excrete some waste products, such as carbon dioxide and water. The skin is another excretory organ that rids the body of wastes through the sweat glands.

Detailed explanation-3: -The lungs are responsible for the excretion of gaseous wastes, primarily carbon dioxide from cellular respiration in cells throughout the body.

Detailed explanation-4: -This is the job of the excretory system. You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled.

Detailed explanation-5: -2: Role of Lungs-In the respiratory system, lungs excrete waste products (carbon dioxide and water). Lungs eliminate these unwanted, waste products from the body, through expiration (exhaling air out from the body).
