Capillaries release oxygen and take up carbon dioxide from surrounding tissues through the process of?.
Osmosis.
Diffusion.
Filtration.
Colloid osmotic pressure.
.
The Correct Answer is B
Choice A rationale:
Osmosis is the process by which water molecules move from an area of high concentration to an area of low concentration across a semi-permeable membrane. It does not directly involve the exchange of oxygen and carbon dioxide in capillaries.
Choice B rationale:
Diffusion is the process by which molecules move from an area of high concentration to an area of low concentration. At the respiratory membrane, where the alveolar and capillary walls meet, gases move across the membranes, with oxygen entering the bloodstream and carbon dioxide exiting.
Choice C rationale:
Filtration is a process that separates particles from a liquid or gas, and it does not directly involve the exchange of oxygen and carbon dioxide in capillaries.
Choice D rationale:
Colloid osmotic pressure refers to the pressure exerted by proteins in a blood vessel’s plasma that usually tends to pull water into the circulatory system. It does not directly involve the exchange of oxygen and carbon dioxide in capillaries.

Correct Answer is A
Explanation
Choice A rationale:
T cells mature in the thymus.
Choice B rationale:
While red bone marrow is where all blood cells, including T cells, originate, T cells specifically mature in the thymus. Choices C and D rationale: Tonsils and the spleen are parts of the lymphatic system, but they are not where T cells mature.
So, the correct answer is Choice A, after analyzing all choices.
Correct Answer is B
Explanation
Choice A rationale:
Vasodilation increases the diameter of blood vessels, which decreases resistance and thus decreases pressure. However, the increased diameter allows for increased blood flow, not decreased.
Choice B rationale:
Vasodilation decreases pressure due to the increased diameter of the blood vessels, and it increases flow because of the reduced resistance to blood flow.
Choice C rationale:
Vasodilation does not increase pressure; it decreases it.
Choice D rationale:
While vasodilation decreases pressure, it does not decrease flow; it increases it.
