D) Filtration

Question

Quizplus · Accepted Answer

Filtration is the process that pushes plasma and dissolved nutrients through the arterial end of the capillary wall.

Answer: A, B, D

- Arteries have a thick tunica media composed of smooth muscle and elastic tissue that allows them to handle high pressure and maintain blood flow.
- The tunica externa is the outermost layer of blood vessels and provides structural support.
- Conducting arteries are large elastic arteries that act as pressure reservoirs to maintain blood flow during diastole.
- Distributing arteries are medium-sized arteries that deliver blood to specific organs or regions.
- Arterioles are resistance vessels that regulate blood flow and pressure.

Answer: C
 Capillaries are the smallest blood vessels and their thin walls allow for exchange of nutrients, gases, and waste products between the blood and tissues.

Answer: D
 Filtration is the process that pushes plasma and dissolved nutrients through the arterial end of the capillary wall.

Answer: D
 Capacitance vessels are veins that are able to store large amounts of blood and thus maintain blood pressure and flow.

Note: The other options are not specifically related to the functions or characteristics of the listed vascular structures.
