Exchange of gas is the function of the circulatory system.Question 18Answera.Trueb.False

The statement is false.

Here's a step-by-step explanation:

1. The circulatory system, also known as the cardiovascular system, is primarily responsible for the transport of blood and nutrients throughout the body. It consists of the heart, blood vessels, and blood.

2. While the circulatory system does play a role in transporting oxygen and carbon dioxide in the blood, the actual exchange of gases - where oxygen enters the blood and carbon dioxide is removed - primarily occurs in the respiratory system, specifically in the lungs.

3. In the lungs, oxygen is taken in from the air we breathe and diffuses into the blood, while carbon dioxide, a waste product of cellular respiration, diffuses out of the blood and is exhaled.

4. Therefore, while the circulatory system is crucial for transporting gases, the actual exchange of gases is not its primary function.

So, the correct answer is b. False. The exchange of gases is primarily the function of the respiratory system, not the circulatory system.
