Blood Functions: Trivia Questions! Quiz - Quiz

What do you know about blood functions? There are prominent jobs that blood has, such as transporting oxygen and nutrients into the body. Other jobs that blood has to include regulating core body temperature, controlling and balancing pH, and storing hormones. Blood consists of of white blood cells, red blood cells, and platelets. This quiz will promote learning about healthy blood functions, and you will be sure to get a type A on an exam.

Questions and Answers

1.

Transport oxygen from lungs to tissues.
- A.
  
  Erythrocytes
- B.
  
  Leukocytes
- C.
  
  Thrombocytes
- D.
  
  Plasma
Correct Answer
A. Erythrocytes

Explanation
Erythrocytes, also known as red blood cells, are responsible for transporting oxygen from the lungs to the tissues. They contain a protein called hemoglobin that binds to oxygen in the lungs and releases it to the body's cells. This process is crucial for delivering oxygen to all the organs and tissues in the body, ensuring their proper functioning. Leukocytes, thrombocytes, and plasma do not have this specific function and are not directly involved in oxygen transport.

2.

The proteinaceous solution in which formed elements circulate and carry nutrients, metabolites, antibodies, hormones, metabolites.
- A.
  
  Erythrocytes
- B.
  
  Leukocytes
- C.
  
  Thrombocytes
- D.
  
  Plasma
Correct Answer
D. Plasma

Explanation
Plasma is a proteinaceous solution in which formed elements circulate and carry various substances such as nutrients, metabolites, antibodies, hormones, and metabolites. Erythrocytes, leukocytes, and thrombocytes are all formed elements found in the plasma. Erythrocytes are responsible for carrying oxygen, leukocytes are involved in the immune response, and thrombocytes are involved in blood clotting. Therefore, the correct answer is plasma as it is the proteinaceous solution that allows for the circulation of these formed elements and the transportation of various substances in the body.

3.

For blood clotting
- A.
  
  Erythrocytes
- B.
  
  Leukocytes
- C.
  
  Thrombocytes
- D.
  
  Plasma
Correct Answer
C. Thrombocytes

Explanation
Thrombocytes, also known as platelets, are responsible for blood clotting. When a blood vessel is damaged, platelets are activated and form a plug at the site of injury, preventing excessive bleeding. They also release chemicals that attract other platelets and help in the formation of a stable clot. Therefore, thrombocytes play a crucial role in the process of blood clotting.

Defensive role
- A.
  
  Erythrocytes
- B.
  
  Leukocytes
- C.
  
  Thrombocytes
- D.
  
  Plasma
Correct Answer
B. Leukocytes

Explanation
Leukocytes, also known as white blood cells, play a defensive role in the body's immune system. They are responsible for fighting off infections and foreign substances. Unlike erythrocytes (red blood cells) which carry oxygen and carbon dioxide, and thrombocytes (platelets) which aid in blood clotting, leukocytes are involved in the body's defense against pathogens and other harmful agents. They can identify and destroy bacteria, viruses, and other foreign invaders, helping to keep the body healthy and free from infection.

Earliest site during fetal development.
- A.
  
  Yolk Sac
- B.
  
  Liver and Spleen
- C.
  
  A & B
- D.
  
  None
Correct Answer
A. Yolk Sac

Explanation
During fetal development, the yolk sac is the earliest site where important processes occur. It plays a crucial role in providing nutrients to the developing embryo before the placenta is fully formed. The yolk sac also aids in the formation of the circulatory system and the production of blood cells. Therefore, the correct answer is the yolk sac.

6.

All are site of Hemopoeisi except;
- A.
  
  Yolk Sac
- B.
  
  Spinal Coloumn
- C.
  
  Liver and Spleen
- D.
  
  Fetal Bone Marrow
Correct Answer
B. Spinal Coloumn

Explanation
The spinal column is not a site of hematopoiesis. Hematopoiesis is the process of blood cell formation, which primarily occurs in specific sites such as the yolk sac, liver, spleen, and fetal bone marrow. The yolk sac is one of the first sites of hematopoiesis in the developing embryo. The liver and spleen are also important sites of hematopoiesis during fetal development. Fetal bone marrow is responsible for producing red blood cells, white blood cells, and platelets. However, the spinal column is not involved in hematopoiesis.

7.

In the fetal bone marrow: at 8 months AOG starts to develop WBC's and platelets at 9 months RBC.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
5 months- WBC 7 months- RBC

8.

Matures into RBC within 24-48 hours.
- A.
  
  Polychromatic erythroblasts
- B.
  
  Orthochromic erythroblasts
- C.
  
  Reticulocytes
- D.
  
  None
Correct Answer
C. Reticulocytes

Explanation
Reticulocytes are immature red blood cells that have recently been released from the bone marrow. They still contain remnants of ribosomes, giving them a reticulated appearance under a microscope. Within 24-48 hours, reticulocytes mature into fully developed red blood cells (RBCs). Therefore, the statement "Matures into RBC within 24-48 hours" accurately describes the transformation process of reticulocytes.
