Blood’s osmotic pressure is greater than the osmotic pressure of the surrounding interstitial fluid that is outside of the capillaries, because
1. there is a higher concentration of sodium and chloride ions in the blood than the interstitial fluid
2. there is a higher concentration of water in the blood than in the interstitial fluid
3. of the plasma proteins present in blood
4. of the hydrostatic pressure produced by the heart’s contractions

During each cardiac cycle two prominent sounds are produced which can be easily heard through a stethoscope where:
I: The first heart sound (lub) is associated with the opening of the tricuspid and bicuspid valves.
II: The second heart sound (dub) is associated with the opening of the semilunar valves.

1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
