Detailed explanation-1: -The lungs are responsible for the excretion of gaseous wastes, primarily carbon dioxide from cellular respiration in cells throughout the body.

Detailed explanation-2: -In the human body, carbon dioxide is formed intracellularly as a byproduct of metabolism. CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation.

Detailed explanation-3: -The oxygen-rich hemoglobin is transported throughout the body and the lungs exhale the carbon dioxide.

Detailed explanation-4: -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-5: -Carbon Dioxide Excretion. Carbon dioxide excretion is a complex process, involving the transport of carbon dioxide in the blood to the pulmonary capillaries, diffusion into the alveoli and ventilation.
