Question 1
1 / -0

The function of vitamin K is in

A
Regulation of calcium and phosphorus metabolism

B
Blood clotting

C
Respiration

D
Carbohydrate metabolism

Solution

Vitamin K plays an important role in blood clotting. It is required by the body for the synthesis of prothrombin by the liver. Prothrombin is a plasma protein which gets converted into thrombin during the clotting process and thus helps in clotting mechanism.
Thus, the correct answer is option B.
Question 2
1 / -0

Blood clot inside a blood vessel is known as

A
Thrombosis

B
Agglutinin

C
Clot

D
Thrombus

Solution

A blood clot that forms inside one of your veins or arteries is called a thrombus. A thrombus may also form in your heart. A thrombus that breaks loose and travels from one location in the body to another is called an embolus.
So, the correct option is 'Thrombus'.
Question 3
1 / -0

Thrombin occurs in vertebrates in

A
The blood and gives it red colour

B
The blood and is important for clotting

C
The liver and is important for bile secretion

D
The stomach and digests proteins

Solution

Thrombin is a substance formed in one of the steps of clotting process from prothrombin. Thrombin, in turn, converts fibrinogen into fibrin which ultimately forms a clot.
Thus, the correct answer is option B.
Question 4
1 / -0

In human, the prothrombin required for blood clotting is produced in

A
Liver

B
Stomach

C
Pancreas

D
Spleen

Solution

In human, the prothrombin required for blood clotting is produced in the liver in the presence of vitamin K. It gets converted into thrombin in the presence of thromboplastin and thus forms an essential step in the clotting process.
Therefore, the correct answer is option A.
Question 5
1 / -0

Which of the metallic ions is essential for blood clotting?

A
Na$$^+$$

B
Ca$$^{++}$$

C
K$$^+$$

D
Fe$$^{++}$$

Solution

Calcium ions along with vitamin K are essential for clotting process as all the reaction in the clotting process take place in the presence of calcium ions. It is very important for the conversion reaction of prothrombin into the thrombin.
Therefore, the correct answer is option B.
Question 6
1 / -0

Oxygen is transported in blood mainly by

A
Leucocytes

B
Erythrocytes

C
Thrombocytes

D
Blood plasma

Solution

Erythrocytes or RBCs act as oxygen carrier molecules which transport oxygen to the body cells. It contains haemoglobin which binds with oxygen to form oxyhaemoglobin and is thus transported in that form.
Therefore, the correct answer is option B.
Question 7
1 / -0

Heparin in blood is released from

A
Clumped platelets

B
Mast-cell granules

C
Non-granulocytes

D
Granulocytes

Solution

Mast-cell is a type of granulocyte. It contains basophil granules that secrete heparin and histamine in blood. They play important role in wound healing.
Therefore, the correct answer is option B.
Question 8
1 / -0

The colour of lymph is

A
Red

B
Pale yellow

C
Colourless

D
Milky

Solution

Lymph is colourless. Lymph is the fluid that circulates throughout the lymphatic system. The lymph is formed when the interstitial fluid (the fluid which lies in the interstices of all body tissues) is collected through lymph capillaries.
Question 9
1 / -0

How many different types of the blood vessels are seen in the body?

A
Three

B
Two

C
Four

D
Five

Solution

There are three different types of blood vessels in the body namely arteries, veins and capillaries. Arteries are the blood vessels which carry blood away from the heart while veins carry blood towards the heart. Capillaries are the smallest blood vessels which connect arteries and veins.
Therefore, the correct answer is option A.
Question 10
1 / -0

Blood clot inside a blood vessel is called as

A
Thrombosis

B
Agglutinin

C
Clot

D
Thrombus

Solution

The blood clot formed inside the blood vessel is called as a thrombus. When this thrombus breaks and travels to different parts of the body, then it is called embolus. Agglutinin is responsible for the agglutination.
Hence, the correct answer is 'Thrombus'
