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 understand why, let's break down the question and examine how the cardiovascular and respiratory systems interact.
The cardiovascular system consists of the heart, blood vessels, and blood. Its primary function is to transport oxygen, nutrients, hormones, and waste products throughout the body. On the other hand, the respiratory system includes the lungs and airways and plays a crucial role in the exchange of oxygen and carbon dioxide between the body and the external environment.
When we inhale, the respiratory system brings in fresh air into the lungs, which contains oxygen. This oxygen needs to be transported to the body's cells to be used for various metabolic processes. This is where the cardiovascular system comes in.
As the oxygen enters the lungs, it diffuses from the air sacs (alveoli) into the tiny blood vessels called capillaries that surround them. The oxygen molecules then bind to the red blood cells in these capillaries. Next, the heart pumps the oxygen-rich blood out of the lungs and into the bloodstream. From there, the blood is carried through arteries to various organs and tissues.
In these organs and tissues, the oxygen is released from the red blood cells and is used by the cells for energy production. At the same time, carbon dioxide, which is a waste product of cellular metabolism, is taken up by the red blood cells and transported back to the lungs. This waste gas is then exhaled from the body during the process of exhaling.
In summary, the cardiovascular system interacts with the respiratory system by transporting oxygenated blood from the lungs to the body's organs and tissues. This ensures that all the cells in the body receive the necessary oxygen for their proper functioning. Therefore, option C, "Blood transports oxygen from the lungs to other organs," is the correct answer.
