Question

decrease in number of white blood cells in blood lead to low immunity. give reason

Answer 1

Heyaa.!!

Here's your answer...

_____________________________________________

WBC or the White Blood Corpuscles(cells)...is responsible
for protection of the body against infections and foreign
particles(antigens).

✳Thus,they are meant to be the cells of the immune
system.

✳WBC are also known as 'soldiers of the body'..

So..decreasing in their number leads to low immunity
as the body won't be able to fight infectious diseases.

Heya user

Here's your answer:-

WBC :-White blood cells will fight against the disease causing agents and antigens..
These only help in keeping the body healthy.

There are different types in it :-

Granuloycytes and Agranulocytes.

Again they are classified:-

Granulocytes:-
Basophills,Easinophills,Neutrophils.

Agranulocytes :-
Lymphocytes and monocytes.

Decrease in WBC leads to weak immune system.
There is a chance of getting attacked by diseases easily.

Have a great day ahead ^_^
