What are some key functions of blood in the human body?

• Transporting oxygen and nutrients, regulating body temperature, and protecting against infection.

• Synthesizing hormones, producing new bone cells, and storing excess fat.

• Generating electrical impulses, breaking down food particles, and filtering waste from the brain.

• Absorbing sunlight, converting it into energy, and controlling muscle contractions.

When whole blood is separated by centrifugation, which component makes up the largest percentage of the total blood volume?

• Erythrocytes

• Leukocytes

• Plasma

• Platelets

What determines an individual's ABO blood type?

• The presence or absence of specific antibodies in the plasma.

• The type of hemoglobin found in red blood cells.

• The presence or absence of specific agglutinogens on the surface of red blood cells.

• The concentration of platelets in the blood.

Which statement accurately describes the characteristics of universal blood types in the ABO system?

• Type O blood is the universal recipient because it has both A and B antigens.

• Type AB blood is the universal donor because it lacks both A and B antigens.

• Type AB blood is the universal recipient because it has both A and B antigens and produces no anti-A or anti-B antibodies.

• Type O blood is the universal donor because it has both anti-A and anti-B antibodies.
