What is the primary function of the lymphatic system?

  1. To transport oxygen and nutrients to cells

  2. To remove waste products from cells

  3. To fight infection

  4. To regulate body temperature


Correct Option: B
Explanation:

The lymphatic system is responsible for collecting and removing waste products, toxins, and excess fluid from tissues and organs.

What are lymph nodes?

  1. Small, bean-shaped structures located along lymph vessels

  2. Organs that produce lymphocytes

  3. Sites where red blood cells are produced

  4. Locations where hormones are released


Correct Option: A
Explanation:

Lymph nodes are small, bean-shaped structures located along lymph vessels. They contain lymphocytes, which are white blood cells that help fight infection.

What is the function of lymph nodes?

  1. To filter and remove harmful substances from lymph fluid

  2. To produce lymphocytes

  3. To store red blood cells

  4. To regulate blood pressure


Correct Option: A
Explanation:

Lymph nodes filter and remove harmful substances, such as bacteria, viruses, and cancer cells, from lymph fluid.

What are lymph vessels?

  1. Thin, delicate tubes that carry lymph fluid

  2. Veins that carry blood back to the heart

  3. Arteries that carry blood away from the heart

  4. Capillaries that allow for the exchange of substances between blood and tissues


Correct Option: A
Explanation:

Lymph vessels are thin, delicate tubes that carry lymph fluid from tissues and organs back to the bloodstream.

What is lymph fluid?

  1. A clear, colorless fluid that circulates throughout the lymphatic system

  2. Blood plasma that has leaked out of blood vessels

  3. Interstitial fluid that has been taken up by lymph vessels

  4. Urine that has been filtered by the kidneys


Correct Option: A
Explanation:

Lymph fluid is a clear, colorless fluid that circulates throughout the lymphatic system. It contains lymphocytes, antibodies, and other substances that help fight infection.

What is the role of the lymphatic system in the immune response?

  1. It produces antibodies that neutralize pathogens

  2. It activates macrophages that engulf and destroy pathogens

  3. It stimulates the production of cytokines that regulate the immune response

  4. All of the above


Correct Option: D
Explanation:

The lymphatic system plays a crucial role in the immune response by producing antibodies, activating macrophages, and stimulating the production of cytokines.

Which of the following is not a function of the lymphatic system?

  1. Transporting oxygen and nutrients to cells

  2. Removing waste products from cells

  3. Fighting infection

  4. Regulating fluid balance


Correct Option: A
Explanation:

The lymphatic system is responsible for removing waste products from cells, fighting infection, and regulating fluid balance. It does not transport oxygen and nutrients to cells.

What is the largest lymph node in the body?

  1. Spleen

  2. Thymus

  3. Liver

  4. Bone marrow


Correct Option: A
Explanation:

The spleen is the largest lymph node in the body. It is located in the upper left quadrant of the abdomen and plays a crucial role in filtering blood, removing old or damaged red blood cells, and storing platelets.

Which of the following is not a type of lymph vessel?

  1. Lymphatic capillaries

  2. Lymphatic collecting vessels

  3. Lymphatic ducts

  4. Veins


Correct Option: D
Explanation:

Veins are blood vessels that carry blood back to the heart. Lymphatic capillaries, lymphatic collecting vessels, and lymphatic ducts are all types of lymph vessels.

What is the primary site of lymphocyte production in the body?

  1. Bone marrow

  2. Thymus

  3. Spleen

  4. Lymph nodes


Correct Option: A
Explanation:

Bone marrow is the primary site of lymphocyte production in the body. Lymphocytes are a type of white blood cell that plays a crucial role in the immune response.

Which of the following is not a type of lymphocyte?

  1. B cells

  2. T cells

  3. Natural killer cells

  4. Red blood cells


Correct Option: D
Explanation:

Red blood cells are not a type of lymphocyte. Lymphocytes are a type of white blood cell that plays a crucial role in the immune response. B cells, T cells, and natural killer cells are all types of lymphocytes.

What is the function of B cells in the lymphatic system?

  1. Producing antibodies against pathogens

  2. Activating macrophages to engulf and destroy pathogens

  3. Releasing cytokines to regulate the immune response

  4. All of the above


Correct Option: A
Explanation:

B cells are responsible for producing antibodies against pathogens. Antibodies are proteins that bind to specific antigens on pathogens, marking them for destruction by other immune cells.

What is the function of T cells in the lymphatic system?

  1. Killing infected cells and cancer cells

  2. Helping B cells produce antibodies

  3. Releasing cytokines to regulate the immune response

  4. All of the above


Correct Option: D
Explanation:

T cells have several functions in the lymphatic system, including killing infected cells and cancer cells, helping B cells produce antibodies, and releasing cytokines to regulate the immune response.

Which of the following is not a common type of lymphatic disorder?

  1. Lymphoma

  2. Leukemia

  3. Multiple sclerosis

  4. Hodgkin's disease


Correct Option: C
Explanation:

Multiple sclerosis is a neurological disorder that affects the brain and spinal cord. It is not a common type of lymphatic disorder. Lymphoma, leukemia, and Hodgkin's disease are all types of lymphatic disorders.

What is the most common type of lymphatic cancer?

  1. Lymphoma

  2. Leukemia

  3. Multiple myeloma

  4. Hodgkin's disease


Correct Option: A
Explanation:

Lymphoma is the most common type of lymphatic cancer. It is a cancer of the lymphatic system that affects lymphocytes.
