Question

Why is gaseous exchange in the circulatory system important to man’s survival?

Answer 1

cells in human body needs continuous supply of oxygen for oxidisation of food and obtain ATP energy. cells also need to throw out the carbon dioxide produced in this reaction. this function is carried out by circulatory system in our body . hemoglobin present in our blood carries these two gases in our body. it takes carbon dioxide from each and every cell of body to lungs . in lungs exchange of gases takes place . by this process carbon dioxide in our body thrown out from body and oxygen is. supplied to the body cells. that's why it is important.

Answer 2

Gaseous exchange is the major pillar for human survival because the gas has the many properties that help human to survive. The oxygen if exist in liquid form, does not have properties that oxygen gas has. Our body need quick and efficient thing that helps to function the body. The exchange of gas in the circulatory system is important to man's survival because the gas needed by body to release energy from food, here gas means oxygen and the extra waste generate needs to remove like carbon dioxide . So, exchange of the gas is important.
