How does the cardiovascular system interact with the respiratory system?
A.
Blood helps the brain interpret different smells.
B.
Blood helps the lungs to inflate and deflate to breathe.
C.
Blood transports oxygen from the lungs to other organs.
D.
Blood transports nutrients from the stomach to other organs.
C. Blood transports oxygen from the lungs to other organs.
The correct answer is C. Blood transports oxygen from the lungs to other organs.
To arrive at this answer, one can consider the functions of the cardiovascular and respiratory systems and how they work together.
The cardiovascular system, including the heart and blood vessels, is responsible for circulating blood throughout the body. It delivers oxygen, nutrients, hormones, and other essential substances to organs and tissues, while also removing waste products.
The respiratory system, which includes the lungs, is responsible for the exchange of oxygen and carbon dioxide between the body and the environment. It brings in oxygen during inhalation and expels carbon dioxide during exhalation.
The interaction between these two systems occurs through the process of breathing. During inhalation, air enters the lungs and oxygen is taken in. The oxygen then diffuses from the lungs into the bloodstream, where it binds to red blood cells. These red blood cells are part of the circulatory system.
The oxygen-rich blood is then pumped by the heart to all the organs and tissues in the body. As the blood reaches each organ, it releases the oxygen, which is used for cellular respiration to produce energy. At the same time, carbon dioxide, a waste product of cellular metabolism, is picked up by the blood.
The carbon dioxide-rich blood is then transported back to the lungs, where it is exhaled during exhalation. The process of exhaling removes carbon dioxide from the bloodstream, ensuring that the body gets rid of the waste product.
So, in summary, the cardiovascular system interacts with the respiratory system by transporting oxygen from the lungs to other organs and tissues, while also removing carbon dioxide.
