blood viscosity stems mainly from the red blood cells but also partly from the ______ in blood.
○ glucose molecules present
○ lipid molecules present
○ formed elements
○ protein molecules present

Explanation:

Blood viscosity is influenced by red blood cells and also by protein molecules (like albumin, globulins) in plasma. Glucose and lipid molecules have minimal impact on viscosity. Formed elements include red blood cells (already mentioned as main source), so the correct factor is protein molecules.

Answer:

D. protein molecules present
