Answer 1

1. ANSWER: Mast cells.

Reason: Mast cells secretes inflammatory mediators like the histamine and also anticoagulant like the heparin.

2. ANSWER: True.

Reason: Neutrophil has segmented nuclei. It has about 4to 5 segments. Hence they are also called as polymorphonuclear neutrophils.

3. ANSWER: Albumin.

Reason: The lipids aee transported by the lipoproteins. But also it is transported by albumin in the blood.

4. ANSWER: Neutrophil.

Reason: Neutrophils are the abundant white blood cells in the blood. It constitutes about 60 to 70% of total WBC.

5. ANSWER: Is formed by the walls of of an alveolus, sandwiched basement membranes, and the walls of pulmonary capillaries.

Reason: Respiratory membrane is membrane that separates the air within the alveoli from the pulmonary capillaries. It is made up of pulmonary capillaries wall, basement membrane and Alveolar wall.

6. ANSWER: True.

Reason: Secondary bronchi also called lobar bronchi arises from the primary bronchi supplies the lobes of the lungs.
