Answer 1

Question 1:

(D) plasma cells.

Plasma cells are the B cells which produce and secrete single antibody type.

Question 2:

(E) helper T lymphocytes.

The majority of the interleukins are synthesized by helper T lymphocytes as well as macrophages ,monocytes and endothelial cells.

Question 3:

(A ,D) cytotoxic T- lymphocytes and Natural killer cells.

Granzymes are serine proteases released by cytoplasmic granules within cytotoxic T- cells and natural killer cells.

Question 4:

(C) vaccines have been proven to cause autism (it is false)

Question 5:

(B) cilia are not required for the mucociliary escalator. (It is false)

The epithelial cells also have small hairs or cilia,the second part of the mucociliary escalator.

Question 6:

Nasopharynx, oropharynx and Laryngopharynx.

Question 7:

False

It is false because the vocal cords are the part of larynx.

The vocal cords are composed of mucus membrane that stretch horizontal across the middle laryngeal cavity.

Question 8:

False.

The respiratory zone corresponds to the lung parenchyma and includes the respiratory bronchioles, alveolar ducts and alveoli.

Question 9:

Lobar ,segmental , terminal bronchioles.

Question 10:

False.

Type 1 alveolar cells comprise the major gas exchange surface of the alveolus and are integral to the maintenance of the permeability barrier function of the alveolar membrane.

Question 11:

False.

It is false because the right lung has three lobes and left lung has two lobes.

Question 12:

(A) Mediastinum.

The thoracic cavity contains the lungs and the heart which are located in the mediastinum.
