Question 1 of 5
Identify the process that allows for the movement of fluid into the capillary at its venous end.
Correct Answer: D
Rationale: Osmosis (D) drives fluid into the capillary at the venous end, where oncotic pressure exceeds hydrostatic pressure, reabsorbing water. Filtration (C) occurs at the arterial end, A/B don’t fit.
Question 2 of 5
Identify the main vessels that deliver oxygen rich blood to the head.
Correct Answer: C
Rationale: The common carotid arteries (C) deliver oxygen-rich blood to the head. Jugulars (A) and brachiocephalic (D) are veins, subclavian (B) supplies arms.

Question 5 of 5
Minimum blood Pressure is in:
Correct Answer: D
Rationale: Venules (D) have low pressure (~10-15 mmHg) post-capillary. Aorta (A, ~100 mmHg), arteries (B, ~80-100 mmHg), and capillaries (C, ~20 mmHg) are higher.
