What is the major component(s) of plasma proteins?
- A.
Globulins
- B.
Albumin
- C.
Fibrogen
- D.
Immunoglobins
- E.
Salt, eggs, and a pinch of sugar
Correct Answer
B. AlbuminExplanation
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.Rate this question:

Where are alpha globulins made? And why is it important?
- A.
Liver; Regulator of the immune Systems
- B.
Spleen: Initiates allergic reactions
- C.
Bone: Responds to Bacterial infections
- D.
Liver; Clotting
- E.
Liver; Sanity
Correct Answer
D. Liver; ClottingExplanation
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.Rate this question:

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
- A.
Neutrophils
- B.
Basophils
- C.
Monocytes
- D.
Macrophages
- E.
T-cells
Correct Answer(s)
A. Neutrophils
B. BasophilsExplanation
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.Rate this question:

___________ account for 1-6% of WBC, releases histmines and is a major response in allergic reactions.
- A.
Basophil
- B.
Monocytes
- C.
T-Cell
- D.
Platelets
- E.
Eosinophil
Correct Answer
E. EosinophilExplanation
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.Rate this question:

The Blood cell that can attack a specific antigen is a(n)
- A.
Monocyte
- B.
Lymphocyte
- C.
Eosinophil
- D.
Neutrophil
- E.
Basophil
Correct Answer
B. LymphocyteExplanation
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.Rate this question:

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)
- A.
Basophils
- B.
Erythrocytes
- C.
Lymphocytes
- D.
Proerythroblast
- E.
Myleoblast
Correct Answer
B. ErythrocytesExplanation
Asking for end product so answer D is incorrectRate this question:
-
- 9.
Order the WBC from most common to least common.
- 10.
What enzyme do platelets produce and what does the enzyme convert and what is the end product.
- A.
Thrombin; T -cells; fibrogen
- B.
Gamma; Globulins; blood clot
- C.
Thromboplastin; prothrombin; blood clot
- D.
The answer is C
- E.
Serotonin; Heparin; mesenchyme
Correct Answer
C. Thromboplastin; prothrombin; blood clotExplanation
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.Rate this question:
