Blood pressure falls with distance from the heart. Using this information, which of the following properly lists the type of blo
Angelina_Jolie [31]

Answer:

The correct answer will be- arteries→capillaries→veins

Explanation:

The circulation of blood in the closed circulatory system flows through blood vessels. These blood vessels show structural differences in response to the pressure exerted by the blood on the surrounding medium.

The blood pressure varies in the circulatory system because the heart pumps the blood with a greater force, so the blood vessel called arteries which carries the blood from the heart posses thicker walls.

The blood pressure reduces until the blood reaches the organs, the blood pressure reduces. Thus the blood in the capillaries has lower pressure.

When blood exits from the organs back to the heart, then the blood pressure is highly reduced as a result, the veins carry the blood with lower pressure.

Thus, arteries→capillaries→veins are the correct answer.
