Haemopoietic And Lymphatic System Quiz - Quiz

The hemopoietic system consists of tissues and organs that make the production of blood possible. The lymphatic system works with vascular structures to drain interstitial fluid into the heart. The lymphatic system is also active in immune responses against infections. How much do you know about these systems? Attempt this quiz to know!

Questions and Answers

1.

Which of these is not a component of blood?
- A.
  
  Erythrocytes
- B.
  
  Cytocytes
- C.
  
  Thrombocytes
- D.
  
  Leucocytes
Correct Answer
B. Cytocytes

Explanation
Cytocytes is not a component of blood. Erythrocytes, thrombocytes, and leukocytes are the three main components of blood. Erythrocytes, also known as red blood cells, are responsible for carrying oxygen to the body's tissues. Thrombocytes, or platelets, play a crucial role in blood clotting to prevent excessive bleeding. Leukocytes, or white blood cells, are part of the immune system and help fight off infections and diseases. Cytocytes is not a recognized component of blood.

2.

Which of these is not part of the hemopoietic system?
- A.
  
  Thymus
- B.
  
  Spleen
- C.
  
  Liver
- D.
  
  Bone marrow
Correct Answer
C. Liver

Explanation
The liver is not part of the hemopoietic system. The hemopoietic system is responsible for the production and development of blood cells. It includes organs such as the bone marrow, thymus, and spleen, which are involved in the production, maturation, and storage of different types of blood cells. The liver, on the other hand, has various functions such as detoxification, metabolism, and production of bile, but it does not play a role in hemopoiesis.

3.

Which of these is the cornerstone of adaptive immune system?
- A.
  
  Erythrocytes
- B.
  
  Thrombocytes
- C.
  
  Leucocytes
- D.
  
  Lymphocytes
Correct Answer
D. LympHocytes

Explanation
Lymphocytes are the cornerstone of the adaptive immune system. They are a type of white blood cell that play a crucial role in recognizing and responding to specific antigens. Lymphocytes are responsible for the production of antibodies, which target and neutralize foreign substances in the body. They also have the ability to remember previous infections, allowing for a faster and more effective immune response upon reinfection. Without lymphocytes, the adaptive immune system would not be able to mount a specific and targeted defense against pathogens.

4.

What is the production of red blood cells called?
- A.
  
  Respiration
- B.
  
  Erythropoiesis
- C.
  
  Hemostasis
- D.
  
  Homeostasis
Correct Answer
B. Erythropoiesis

Explanation
Erythropoiesis is the correct answer because it refers to the process of production of red blood cells. Respiration is the process of exchanging gases, Hemostasis refers to the process of stopping bleeding, and Homeostasis is the maintenance of a stable internal environment. Therefore, Erythropoiesis is the most appropriate term for the production of red blood cells.

5.

Which of these cells is not involved in myelopoiesis?
- A.
  
  Megakaryocytes
- B.
  
  Macrophages
- C.
  
  B-cells
- D.
  
  Granulocytes
Correct Answer
C. B-cells

Explanation
B-cells are not involved in myelopoiesis. Myelopoiesis is the process of producing cells of the myeloid lineage, which includes cells like granulocytes (neutrophils, eosinophils, basophils), monocytes (which differentiate into macrophages), and megakaryocytes (which produce platelets). B-cells, on the other hand, are part of the lymphoid lineage and are involved in producing antibodies and immune responses. Thus, B-cells are not involved in myelopoiesis.

6.

Which of these is not a lymphocyte?
- A.
  
  B-cells
- B.
  
  T-cells
- C.
  
  Granulocytes
- D.
  
  Natural killer cells
Correct Answer
C. Granulocytes

Explanation
Granulocytes are not lymphocytes. Lymphocytes are a type of white blood cell that play a key role in the immune system. B-cells and T-cells are two types of lymphocytes that are responsible for recognizing and attacking specific pathogens. Natural killer cells are also a type of lymphocyte that can kill infected cells and cancer cells. On the other hand, granulocytes are a different type of white blood cell that are involved in the inflammatory response and defense against certain infections.

Rate this question:
7.

Which of these occurs when T-cells are being produced?
- A.
  
  Necrosis
- B.
  
  Apoptosis
- C.
  
  Cyanosis
- D.
  
  Stenosis
Correct Answer
B. Apoptosis

Explanation
Apoptosis is a process of programmed cell death that occurs during the production of T-cells. It is a natural and controlled process that eliminates old, damaged, or unnecessary cells, allowing for the development of new T-cells. Necrosis, on the other hand, is a type of cell death caused by injury or infection. Cyanosis refers to a bluish discoloration of the skin due to low oxygen levels, while stenosis is the narrowing of a blood vessel or other passageway.

8.

Which of these does not contain lymphoid follicles?
- A.
  
  Adenoids
- B.
  
  Spleen
- C.
  
  Skin
- D.
  
  Pituitary gland
Correct Answer
D. Pituitary gland

Explanation
The pituitary gland does not contain lymphoid follicles. Lymphoid follicles are small clusters of lymphoid tissue that contain immune cells such as lymphocytes. The adenoids, spleen, and skin all contain lymphoid follicles and are involved in the immune response. However, the pituitary gland is not part of the immune system and does not contain lymphoid follicles. It is a small gland located at the base of the brain that produces and releases hormones that regulate various bodily functions.

9.

Which of these is the site of the maturation of T-cells?
- A.
  
  Payer's patches
- B.
  
  Tonsils
- C.
  
  Thymus
- D.
  
  Spleen
- E.
  
  Thymus
Correct Answer
E. Thymus

Explanation
The Thymus is the site of maturation of T-cells. T-cells are a type of white blood cell that play a crucial role in the immune response. The Thymus is a gland located in the upper chest, behind the sternum. It is responsible for the development and maturation of T-cells, which occurs during childhood and adolescence. The Thymus provides an environment where T-cells can undergo selection and maturation, acquiring the ability to recognize and respond to specific antigens. Therefore, the Thymus is considered the primary organ involved in T-cell development and maturation.

10.

Which of these refers to one or more enlarged lymph nodes?
- A.
  
  Retinopathy
- B.
  
  Nephropathy
- C.
  
  Lymphadenopathy
- D.
  
  Hepatopathy
Correct Answer
C. LympHadenopathy

Explanation
Lymphadenopathy refers to one or more enlarged lymph nodes. It is a condition that occurs when the lymph nodes become swollen due to infection, inflammation, or cancer. This can be caused by various factors such as viral or bacterial infections, autoimmune diseases, or malignancies. Lymphadenopathy can be localized, affecting only certain lymph nodes, or generalized, affecting multiple lymph nodes throughout the body. It is important to identify the underlying cause of lymphadenopathy in order to determine the appropriate treatment.
