Answer 1

Answer

1. Option D) Is initiated by arterioles

• Vasocontriction is narrowing of the blood vessels (arteries and arterioles)
• It occurs immediatetly in arterioles after the injury to prevent blood loss.

2. Option B) None of the above

• Fluid compartment refers to three main compartments containing water in the body.
  - They are : Intracellular, Extracellular and Interstitial

3. Option D) Functions in water reabsorption

• Large intestine contains undigested food material.
• It absorbs water from the matter to solidify it and produce feces.

4. Option B) Reinforce the AV valves

• The chordae tendineae are strings that are attaches to atrioventricular valves.
• It helps to support the AV valves and hold them in place during ventricular contraction.
