Blood Components and Functions

What is the function of plasma in blood?

• Plasma transports nutrients, hormones, and waste products throughout the body.

• Plasma helps in the clotting of blood only.

• Plasma is responsible for producing red blood cells.

• Plasma acts as the main component of white blood cells.

What is the function of red blood cells in blood?

• Red blood cells carry oxygen from the lungs to the body tissues and carbon dioxide from the tissues to the lungs.

• Red blood cells produce antibodies to fight infections.

• Red blood cells help in blood clotting.

• Red blood cells regulate body temperature.

What is the function of white blood cells in blood?

• White blood cells defend the body against infection and disease.

• White blood cells transport oxygen throughout the body.

• White blood cells help in blood clotting.

• White blood cells provide energy to muscles.

What is the function of platelets in blood?

• Platelets help in blood clotting to prevent bleeding.

• Platelets transport oxygen in the blood.

• Platelets fight against infections.

• Platelets produce hormones in the body.

What is the role of hemoglobin in carrying oxygen and carbon dioxide?

• Hemoglobin binds to oxygen in the lungs and carries it to tissues; it also carries carbon dioxide from tissues to the lungs for exhalation.

• Hemoglobin breaks down oxygen and carbon dioxide into water and energy.

• Hemoglobin only transports nutrients, not gases, in the blood.

• Hemoglobin binds to glucose in the blood and helps regulate blood sugar levels.

What is the basic structure and function of arteries?

• Arteries have thick, elastic walls and carry blood away from the heart under high pressure.

• Arteries have thin, non-elastic walls and carry blood towards the heart under low pressure.

• Arteries have valves to prevent backflow and carry blood from the lungs to the heart.

• Arteries have porous walls and are involved in the exchange of gases and nutrients with tissues.

What is the basic structure and function of capillaries?

• Capillaries are tiny blood vessels with thin walls that allow exchange of substances between blood and tissues.

• Capillaries are large blood vessels that carry blood away from the heart.

• Capillaries are thick-walled vessels that prevent any exchange of substances.

• Capillaries are muscular tubes that transport oxygen only.

What is the basic structure and function of veins?

• Veins have thinner walls than arteries and carry blood toward the heart under lower pressure.

• Veins have thicker walls than arteries and carry blood away from the heart under high pressure.

• Veins have muscular walls and transport oxygen-rich blood to the body tissues.

• Veins have valves to prevent blood from entering the heart under high pressure.
