A) colloid osmotic pressure C) capillary hydrostatic pressure B) interstitial fluid osmotic pressure D) oncotic pressureExplanation / Answer
Answer
5) Skeletol muscle pump assist to return blood to the Archie's heart.
- It is important for increasing the venous return.
Option A
6) Acetylcholine hormone decreases heart rate, cardiac output and blood pressure.
- It is released by parasympathetic nervous system.
Option A
7) Increase in blood pressure is detected by Baroreceptors.
- They are located in carotis sinus of aortic arch.
Option C
8) Atrial natriuretic peptide is releases to decerase the blood pressure.
- It is secreted by the atria of the heart.
Option B
9) Increase sugar intake is NOT a treatment for hypertension.
Option C
10) Water crosses capillary beds by diffusion.
Option B
11) At the arteriolar end of capillary, capillary hydrostatic pressure is the greatest.
Option C
