I am entering the question below because I answered it befor

I am entering the question below because I answered it before I sent it to Chegg. I was given two different answers by two different people. What do you believe the correct answer to be? I personally choose b,c, and g. I know the first part of a is correct, but not sure about the second half. Thanks 5. Select all of the TRUE statements regarding our blood vessels. a. arterioles can be called our “resistance vessels” because this is where blood encounters its greatest decline in blood pressure b. a venous anastomosis is where two or more veins drain an area in common c. there are about 10 billion capillaries, yet only about 5% of our blood is in them at any one time d. venules have only the tunica interna and the tunica externa, they have NO tunica media e. about 40% of the blood is in veins at any given time f. capillaries are known as blood reservoirs for extra blood g. veins of the appendages that are greater than 2 mm in diameter have valves made of folds in the intima and are similar to shape and function of the semilunar valves h. compared to their companion arteries, veins have a very thick tunica intima which contains an internal elastic membrane, a thin tunica media with no external elastic membrane, and a very thin tunica adventitia (externa)

Solution

1. Arterioles are resistance vessels, which constricts to increase the resistance of blood flow and relaxes to decrease resistance of blood flow. So, this statement is correct.

2. Venous anastosmosis is the connection between two veins. So, this statement is true.

3. There are about 40 billion capillaries in the body, they hold only 5% of total blood volume. So this statement is not true.

4. Venules have one to two layers if sooth muscle cells and a thin tunica externa. SO statement d is not true.

5. Veins called capacitance vessels, and blood reservoirs — they can hold hold upto 65% of the body\'s blood supply. This statement is not true.

6. Veins acts as blood reservoir for extra blood not the capillaries. SO, this statement is not true.

7. This statement is correct.

8. This statement is not true. The veins have thin tunica externa and no tunica media.
