Blood and Blood Vessels

What are the components of blood?

• Hemoglobin, Platelets, Lymphocytes

• Plasma, Red Blood Cells, White Blood Cells

• Plasma, Red Blood Cells, White Blood Cells, Platelets

• Serum, Neutrophils, Erythrocytes

What is the function of red blood cells?

• Producing insulin

• Regulating body temperature

• Transporting oxygen and carbon dioxide

• Digesting food

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

• Regulate body temperature

• Aid in muscle growth

• Help fight infections and foreign invaders in the body.

• Help with digestion

Explain the difference between arteries and veins.

• Arteries carry oxygenated blood, veins carry deoxygenated blood.

• Arteries have valves, veins do not.

• Arteries carry deoxygenated blood, veins carry oxygenated blood.

• Arteries are thin-walled, veins are thick-walled.

What is the composition of plasma?

• Water, electrolytes, glucose, hormones, gases, albumin, globulins, fibrinogen

• Enzymes, antibodies, waste products

• Proteins, lipids, carbohydrates, vitamins, minerals

Describe the structure of capillaries.

• Capillaries have a thick layer of connective tissue.

• Capillaries are made up of multiple layers of endothelial cells.

• Capillaries consist of a single layer of endothelial cells.

• Capillaries are composed of smooth muscle cells.

What are the different types of white blood cells?

• Hemoglobin

• Plasma

• Platelets

• Lymphocytes

• Phagocytes

How does blood clotting occur?

• Excessive sweating does not cause blood clotting

• Blood clotting is not related to low iron levels

• Blood clotting involves platelet activation, clotting factors release, and fibrin mesh formation

• Dehydration does not lead to blood clotting
