[Campbell Biology P.999] Which of the following statements accurately describe the functions... | Practice Question

Which of the following statements accurately describe the functions of specific components found in human blood, according to the provided text? Select all that apply.

  • A: Platelets are primarily responsible for transporting oxygen throughout the body.
  • B: Plasma proteins contribute to blood pH regulation and osmotic pressure.
  • C: Leukocytes are crucial for defending the body against microorganisms.
  • D: Erythrocytes play a significant role in blood clotting.

Explanation

The text explicitly states: 'Plasma proteins influence blood pH, osmotic pressure, and viscosity' and 'Leukocytes... function in defense against microorganisms and foreign substances in the blood.' This confirms options B and C. Platelets, not erythrocytes, function in blood clotting, and erythrocytes transport oxygen, making options A and D incorrect.
