Blood Lymphatic and Immune Quiz

What is the main function of red blood cells?

• Carry oxygen and carbon dioxide

• Regulate body temperature

• Transport nutrients to the cells

• Produce insulin

Explain the role of white blood cells in the immune system.

• They transport oxygen to the body's cells.

• They help in digestion of food.

• They identify and destroy foreign invaders in the body.

• They regulate the body's metabolism.

Describe the structure of a blood vessel and its function.

• The structure of a blood vessel includes three layers: the tunica intima, tunica media, and tunica externa. The function of a blood vessel is to transport blood throughout the body, delivering oxygen and nutrients to tissues and removing waste products.

• The structure of a blood vessel includes only one layer: the tunica externa. The function of a blood vessel is to produce red blood cells.

• The structure of a blood vessel includes four layers: the tunica intima, tunica media, tunica externa, and tunica interna. The function of a blood vessel is to produce hormones.

• The structure of a blood vessel includes two layers: the tunica media and tunica externa. The function of a blood vessel is to regulate body temperature.

How does blood clotting prevent excessive bleeding?

• By breaking down the platelet plug to increase bleeding

• By increasing the flow of blood to the wound to worsen the bleeding

• By diluting the blood to reduce its ability to clot

• By forming a fibrin clot to reinforce the platelet plug and prevent excessive bleeding

What are the main components of the lymphatic system?

• heart, lungs, liver, kidneys

• lymph nodes, lymphatic vessels, thymus, spleen, and tonsils

• stomach, intestines, pancreas, gallbladder

• brain, spinal cord, nerves, muscles

Explain the function of the lymph nodes in the immune system.

• Lymph nodes filter lymph fluid and trap foreign substances for immune response.

• Lymph nodes regulate body temperature.

• Lymph nodes produce red blood cells for the immune system.

• Lymph nodes store excess water in the body.

What is the role of the spleen in the lymphatic system?

• Regulating body temperature

• Producing insulin

• Filtering blood and storing/producing white blood cells and platelets

• Digesting food and absorbing nutrients

Describe the process of phagocytosis in the immune response.

• Phagocytosis is the process by which immune cells engulf and digest foreign particles or pathogens.

• Phagocytosis is the process of producing antibodies to attack foreign particles.

• Phagocytosis is the process of releasing toxins into the body to fight off pathogens.

• Phagocytosis is the process of creating a barrier to prevent pathogens from entering the body.

Explain the difference between innate and adaptive immunity.

• Innate immunity is non-specific and present at birth, while adaptive immunity is specific and develops over time.

• Innate immunity is only present in animals, while adaptive immunity is only present in plants.

• Innate immunity is acquired through vaccination, while adaptive immunity is not affected by vaccines.

• Innate immunity is specific and develops over time, while adaptive immunity is non-specific and present at birth.

What are the stages of the immune response to an infection?

• The stages of the immune response to an infection are: recognition, activation, response, and resolution.

• The stages of the immune response to an infection are: confusion, panic, and surrender.

• The stages of the immune response to an infection are: hesitation, procrastination, and indifference.

• The stages of the immune response to an infection are: denial, bargaining, and acceptance.
