Questions and Answers

What is the role of red blood cells in the body?

  • Exchanging hormones, lipids, salts, water molecules, and small proteins with extracellular fluid

    • Which component of blood exerts a water-binding effect known as colloidal osmotic pressure?

  • Albumin (correct)
  • Blood coagulation factors
  • Anti-proteases
  • Immunoglobulins

    • Which component makes up approximately 90% of the plasma?

  • Protein
  • Inorganic salts
