Weekly Quiz Competition

Question 1
1 / -0

Which statement is true about WBC?

A
Non-nucleated

B
Deficiency causes leukaemia

C
Can squeeze through blood capillaries

D
None of the above

Solution

WBC's are amoeboid in shape due to which they can easily squeeze through the walls of the capillaries at the site of injury by the process known as diapedesis and engulf the damaged cells by phagocytosis. They are nucleated cells and excess of WBCs causes cancer known as leukaemia.
So, the correct answer is option C.
Question 2
1 / -0

Which clotting factor makes anti-heparin?

A
Albumin

B
Fibrin

C
Fibrinogen

D
Thromboplastin

Solution

Basophils and mast cells release heparin that prevents clotting and promotes blood flow. Thromboplastin is released by platelets at injured tissue that makes anti-heparin and initiates the clot formation. Fibrinogen is a soluble blood protein that becomes insoluble and forms fibrin strands during last steps of clotting. Albumins serve to maintain the osmotic concentration of blood. Thus, the correct answer is D.
Question 3
1 / -0

Prothrombin, albumin and fibrinogen are synthesised by

A
Pancreas

B
Bone marrow

C
Spleen

D
Liver

Solution

Prothrombin is a component of blood which helps in blood coagulation. It is mainly synthesized by the liver. Prothrombin of blood plasma is converted to thrombin in the presence of thromboplastin and calcium ion during blood clotting. Albumin is a globular protein, produced by the liver. It occurs in blood plasma and is the most abundant blood protein in mammals. Albumin functions primarily as a carrier protein for steroids, fatty acids, and thyroid hormones in the blood and plays a major role in stabilizing extracellular fluid volume by contributing to oncotic pressure.
Fibrinogens are large, soluble and complex glycoproteins in vertebrates, that helps in the formation of blood clots. It is synthesized in the liver by the hepatocytes. The fibrinogen molecule is converted by thrombin into fibrin during blood clot formation
So, the correct answer is 'Liver'
Question 4
1 / -0

In a rabbit, the RBCs are formed from

A
Myeloblast

B
Agranulocyte

C
Thymocyte

D
Lymphoblast

Solution

The RBCs in rabbit are formed from the myeliod lineage of hemocytoblasts or stem cells more specifically the myeloblast found in the stroma of the bone marrow. Hence the correct option is A.
Question 5
1 / -0

Spleen and thymus are hematopoietic for:

A
RBC

B
WBC

C
Platelets

D
All of the above

Solution

The spleen and thymus are lymphoid organs of the body. The lymphoid system of the body is a part of the circulatory system and immune system and it is involved in the production of cells and also in the destruction of cells
In the spleen and thymus, 20-30% of WBCs are formed while RBCs and platelets are formed in the bone marrow.
Hence, the correct option is B.
Question 6
1 / -0

Platelets are a source of

A
Fibrinogen

B
Calcium

C
Thromoboplastin

D
Heamoglobin

Solution

Platelets are a source of thromboplastin. Thromboplastin is a plasma protein aiding blood coagulation through catalyzing the conversion of prothrombin to thrombin. It is a complex enzyme that is found in the brain, lung, and other tissues and especially in blood platelets and that functions in the conversion of prothrombin to thrombin in the clotting of blood, called as thrombokinase.
Question 7
1 / -0

Which clotting factor has been rejected now?

A
VIII

B
VII

C
VI

D
V

Solution

Clotting factor VIII is the antihemophilic factor while factor VII serves as an accelerator of serum prothrombin conversion. Clotting factor V is proaccelerin. Clotting factor VI was once considered to have clotting function but is now rejected. Thus, the correct answer is C.
Question 8
1 / -0

Which is unrelated to blood coagulation?

A
Fibrinogen

B
Fibrin

C
Bilirubin

D
Calcium

Solution

One of the initial steps in blood coagulation is the release of thromboplastin that interacts with other clotting factors and calcium ions. Fibrinogen is a soluble blood protein that becomes insoluble and forms fibrin strands during last steps of clotting. Bilirubin is the breakdown product of hemoglobin. Thus, the correct answer is C.
Question 9
1 / -0

Blood clotting requires

A
Na$$^+$$ and K$$^+$$

B
Na$$^+$$ and prothrombin

C
Ca$$^{2+}$$ and thromboplastin

D
None of the above

Solution

$$Ca^{++}$$ and thromboplastin are needed for blood clotting. Coagulation (thrombogenesis) is the process by which blood forms clots. The process of clotting starts by the release of thromboplastin by the platelets and resquires calcium ions.
Question 10
1 / -0

Which of the following is an anticoagulant and checks blood coagulation in blood vessels?

A
Prothrombin

B
Globulin

C
Thromoboplastin

D
Heparin

Solution

Heparin is a natural anticoagulant produced in the liver and helps in checking the clotting of blood inside blood vessels.
