Details Of Immunity

Antibodies in our body are complex:

1. lipoproteins

2. steroids

3. prostaglandins

4. glycoproteins

Lysozyme that is present in perspiration, saliva, and tears destroys:

1.	certain fungi	2.	certain types of bacteria
3.	all viruses	4.	most virus-infected cells

To which type of barriers under innate immunity, do the saliva in the mouth and the tears from the eyes, belong?

1. Cytokine barriers

2. Cellular barriers

3. Physiological barriers

4. Physical barriers

A person likely to develop tetanus is immunised by administering:

1. dead germs

2. preformed antibodies

3. wide spectrum antibiotics

4. weakened germs

In which one of the following options the two examples are correctly matched with their particular type of immunity?

	Examples	Type of immunity
(a)	Polymorphonuclear leukocytes and monocytes	Cellular barriers
(b)	Anti-tetanus and anti-snake bite injection	Active immunity
(c)	Saliva in mouth and tears in eyes	Physical barriers
(d)	Mucus coating of the epithelium lining the urinogenital tract and HCl in the stomach	Physiological barriers

1. (a)
2. (b)
3. (c)
4. (d)

The cell-mediated immunity inside the human body is carried out by:
1. B-lymphocytes
2. Thrombocytes
3. Erythrocytes
4. T-lymphocytes

Grafted kidney may be rejected in a patient due to?

1.	Humanol immune response
2.	Cell-mediated immune response
3.	Passive immune response
4.	Innate immune response

Transplantation of tissues/organs fails often due to non-acceptance by the patient's body. Which type of immune-response is responsible for such rejections?

1.	Cell-mediated immune response
2.	Hormonal immune response
3.	Physiological immune response
4.	Autoimmune response

Which of the following immune responses is responsible for the rejection of kidney graft?

1.	Cell-mediated immune response
2.	Auto-immune response
3.	Humoral immune response
4.	Inflammatory immune response

Select the incorrect statement with respect to acquired immunity.

1.	Acquired immunity is non-specific type of defense present at the time of birth.
2.	Primary response is produced when our body encounters a pathogen for the first time.
3.	Anamnestic response is elicited on subsequent encounters with the same pathogen.
4.	Anamnestic response is due to memory of first encounter.

Identify the statement that is NOT correct.

1.	Antigen binding site is located at C-terminal region of antibody molecules.
2.	Constant region of heavy and light chains are located at C-terminus of antibody molecules.
3.	Each antibody has two light and two heavy chain.
4.	The heavy and light chains are held together by disulfide bonds.
