NEET BIOLOGY

Detailed explanation-1: -Complete answer: Yes, it is true that animals breathe oxygen and give out carbon dioxide; this is done in the process of respiration. When we inhale or breathe in, we pull air mainly containing nitrogen and oxygen into our lungs, and whenever we exhale or breathe out, we mostly release carbon dioxide.

Detailed explanation-2: -Animals do just the opposite of plants: they take in air from the atmosphere, use the oxygen, and exhale the CO2.

Detailed explanation-3: -Respiration in animals such as humans occurs with the help of the lungs. The animals take oxygen from the air by using their lungs that send the usable oxygen to the cells of the animals to break down the taken food to obtain the energy.

Detailed explanation-4: -Delicate blood vessels extract the oxygen from the air. The blood helps to transport the oxygen to the cells and tissue (exception: tracheal breathing) to be “processed” there. All there is left then is some carbon dioxide, which is transported out of the tissue and cells when breathing out.

Detailed explanation-5: -Answer and Explanation: The respiration process occurs in all types of living things like plants, human being, animals, etc.
