Question 10

MATCHING
Indicate which type of the vessel performs the function listed by writing the appropriate letter in the blank using the answer code below.
-Serve as low-resistance passageways from the heart to the tissues.

Accepted Answer

Arteries are the vessels that transport blood away from the heart to the body tissues. They have a muscular layer that allows them to contract and dilate, regulating blood pressure and flow.

Answer: B)arterioles
 Arterioles are smaller branches of arteries that further regulate blood flow and distribution to specific tissues.

Answer: C)capillaries
 Capillaries are the smallest blood vessels that connect arterioles and venules, allowing for the exchange of oxygen, nutrients, and waste products between the blood and the tissues.

Answer: D)veins
 Veins are the vessels that transport blood from the tissues back to the heart. They have one-way valves that prevent blood from flowing backward, and they rely on skeletal muscle contractions to aid in blood flow.

Answer: E)lymphatics
 Lymphatics are vessels that transport lymph, a fluid that contains white blood cells and waste products, away from the tissues and toward the lymph nodes. They help to maintain fluid balance and immunity.

Question 11

MATCHING
Indicate which type of the vessel performs the function listed by writing the appropriate letter in the blank using the answer code below.
-Portion of the circulatory system through which the velocity of blood flow is the slowest.

Accepted Answer

Capillaries are the smallest blood vessels where the exchange of gases, nutrients, and waste occurs, and they have the slowest blood flow velocity to facilitate this exchange.

Question 12

Question 16

MATCHING
Indicate which type of the vessel performs the function listed by writing the appropriate letter in the blank using the answer code below.
-Changes in the radius of this vessel type regulate the distribution of the cardiac output to various areas of the body.

Accepted Answer

Arterioles are the vessels that regulate the distribution of the cardiac output to various areas of the body through changes in their radius. The other vessel types listed do not perform this function.

-Major resistive vessels.

Accepted Answer

The answer of MATCHING
Indicate which type of the vessel performs...
