Here the question is all about the blood and its components.
00:04
So what is blood? blood is the kind of body fluid which is the part of circulatory system and blood is necessary to deliver the necessary substances or the essential substances for example nutrients and oxygen to the cells and it transports the metabolic west products away from those cells.
00:34
We go through the components of blood or the composition of blood then the blood components are mainly the different kinds of blood cells which are suspended in the blood plasma yes now if we talk about the blood cells so the blood cells are of three types red blood cells or red blood corpusels wbc, there is white blood cells and the platelets.
01:10
Rbcs are also known as the erythrocytes.
01:16
Wbcs are also known as leukosides and platelates are also known as thrombocytes.
01:25
Again, if we focus on the wbcs or the white blood cells, then white blood cells are of two different types.
01:32
It may be the granulocytes and it can be the agranulocytes.
01:44
Again, this granulocytes can be differentiated into three.
01:48
It may be the neutrophils, eocinophils and the basophils.
01:57
While the agranulocytes are of two major types, the first is lymphocytes and the second is monocytes.
02:09
And if it enters into the tissues then it can be called as the macrophages now such lymphocytes are of three different types so here i am writing about the lymphocytes of three types the first is b lymphocytes also called as b cells then the second is t lymphocytes which are also known as t cells and the third is nk cells or the natural cells.
02:48
Here the b -limphosites which will participate in the processes of humoral immunity then t -lymphocytes participate in the processes of cellular immunity and the nk cells are the natural killer lymphocytes they show the natural cytotoxicity against cancer cells and virus -infected cells so here we have the question saying the types of lymphocytes so there are three major types of lymphocytes so there's the b -limphosites t -limphosites and the natural killer cells or natural killer lymphocytes and here we have the first option saying the t cells so t cells are the types of lymphocytes that is the correct over here and this is our answer here as we can see from this chart that the types of blood cells so here the answer will be the t lymphocytes the second option given here is the neutrophils so neutrophils are the types of granulocytes and ultimately it is the type of wbc...
