Answer 1

1.Intrapulmonary pressure refers to the pressure which occurs in the pleural cavity

Pressure within alveoli can lead to collapse

The pressure in the intrapleural region is less than the external or atmospheric temperature

Difference between atmospheric pressure and respiratory pressure occurs in pulmonary ventilation

Ans:Pressure within pleural cavity

2.Fibrinogen is related to clotting factors any issues in it can later the clotting mechanism

Fever with pain occurs in case of infection

Paleness occurs when there is problems or lack of certain blood cells

Swelling occurs as a result of inflammatory process

Ans:loss of blood clotting

3.The cluster if lymphoid organs is termed to be lymph nodes.

Lymphoid follicles are present in the tissue

Lymphatics includes the entire lymph system

Lacteals present in small intestine

Ans:lymph nodes

4.Adaptive immunity has a typical characteristic of storing information and acting as a memory reservoir and can attack the same antigen when it comes in the consecutive attack

It does not need several days to be activated as it is first activated

It responds one after the other when infection occurs

It does not use antibodies to kill cells

Ans: its memory cells that provide quicker ,lather and more efficient immune response upon second and subsequent exposure to antigen
