Blood & White Blood Cell Quiz

1. What is the lifespan of red blood cells (RBC)?

60 hours

10 weeks

120

45

120 days

Answer C is incorrect because it was not specific enough

Explanation

Answer C is incorrect because it was not specific enough

2. Our Student Vice President, Aaron, has just donated blood. Shortly thereafter, his bone marrow is gearing up to replace the loss. Which of the formed elements will be produced in the greatest amount? (Hint: Asking for end product)

Basophils

Erythrocytes

Lymphocytes

Proerythroblast

Myleoblast

Asking for end product so answer D is incorrect

Explanation

Asking for end product so answer D is incorrect

3. What is the major component(s) of plasma proteins?

Globulins

Albumin

Fibrogen

Immunoglobins

Salt, eggs, and a pinch of sugar

Albumin is the major component of plasma proteins. It is a protein found in the blood and is responsible for maintaining the osmotic pressure of the blood, transporting hormones, fatty acids, and drugs, and regulating the pH balance of the blood. Globulins, fibrogen, and immunoglobins are also components of plasma proteins, but albumin is the most abundant and plays a crucial role in various physiological processes.

4. The Blood cell that can attack a specific antigen is a(n)

Monocyte

Lymphocyte

Eosinophil

Neutrophil

Basophil

Lymphocytes are a type of white blood cell that play a crucial role in the immune system. They are responsible for recognizing and attacking specific antigens, such as bacteria, viruses, and other foreign substances. Lymphocytes are able to do this through the presence of specialized receptors on their surface that can bind to specific antigens. Once bound, lymphocytes can initiate an immune response to eliminate the antigen. Therefore, lymphocytes are the blood cells that can attack a specific antigen.

5. Of the following which are granular white blood cells (WBC) - meaning lobed nuclues and cytoplasmic granules are apparent? (May have more than one correct asnwer

Neutrophils

Basophils

Monocytes

Macrophages

T-cells

Neutrophils and Basophils are granular white blood cells (WBC) because they have a lobed nucleus and cytoplasmic granules that are visible. Monocytes, Macrophages, and T-cells do not have lobed nuclei or visible cytoplasmic granules, so they are not granular WBCs.

6. What enzyme do platelets produce and what does the enzyme convert and what is the end product.

Thrombin; T -cells; fibrogen

Gamma; Globulins; blood clot

Thromboplastin; prothrombin; blood clot

The answer is C

Serotonin; Heparin; mesenchyme

Platelets produce the enzyme thromboplastin. Thromboplastin converts prothrombin into thrombin. Thrombin then plays a crucial role in the formation of blood clots. Therefore, the end product of this process is a blood clot.

Platelets produce the enzyme thromboplastin. Thromboplastin converts prothrombin into thrombin. Thrombin then plays a crucial role in the formation of blood clots. Therefore, the end product of this process is a blood clot.

7. RBCs are the most abundent cell in the blood and round in shape

False

True

RBC are biconcave in shape

Explanation

RBC are biconcave in shape

8. ___________ account for 1-6% of WBC, releases histmines and is a major response in allergic reactions.

Basophil

Monocytes

T-Cell

Platelets

Eosinophil

Eosinophils account for 1-6% of white blood cells (WBC) and are known to release histamines, which are involved in allergic reactions. This makes eosinophils a major player in the immune response to allergies.

Eosinophils account for 1-6% of white blood cells (WBC) and are known to release histamines, which are involved in allergic reactions. This makes eosinophils a major player in the immune response to allergies.

9. Where are alpha globulins made? And why is it important?

Liver; Regulator of the immune Systems

Spleen: Initiates allergic reactions

Bone: Responds to Bacterial infections

Liver; Clotting

Liver; Sanity

Alpha globulins are made in the liver. This is important because alpha globulins play a crucial role in the process of blood clotting. They are involved in the coagulation cascade, which helps to stop bleeding by forming blood clots. Without alpha globulins, the body would have difficulty in clotting blood, leading to excessive bleeding and potential life-threatening situations. The liver's production of alpha globulins ensures that the clotting process can occur effectively when needed.
