Question : Blood is commonly called red vascular connective tissue as its matrix is fluidy, mobile and fibre-free, and is red-coloured due to presence of haemoglobin in its RBCs. Blood is formed of two components: Plasma and Blood corpuscles. Its blood corpuscles are of three types Erythrocytes, Leucocytes and blood platelets. Leucocytes are of five types which are adapted to perform different functions. Answer the following questions related to blood: (i) List two structural peculiarities of its RBCs of human blood. (ii) Tabulate two differences between its five types of leucocytes. (iii) Define diapedesis .

Answer»

Solution :(i) RBCs of human BLOOD are denucleated and biconcave, and is bounded by an elastic PLASMA membrane while their cytoplasm CONTAINS large amount of HAEMOGLOBIN.

(III) Capability of leucocytes of blood to come out of blood capillaries by amoeboid movements is called diapedesis .

Question : Blood Corpuscles.

Answer»

Solution :Erythrocystes, Leucocytes and Platelets are collectively called formed elemets.
These elements constitute nearly 45 percents of the blood.
(a) Erythrocytes /Red blood cells (RBC) are the most abundant of all the cells in the blood.
A healthy adult man has an average 5 million to 5.5 million of RBCs `mm^(3)` of blood.
RBCs are devoid of nucleus in most of the mammals.
They are biconcave in shape.
They have a red coloured, iron containing complex protein called haemoglobin
A healthy indivdual has 12 - 16 gms of haemoglobin in every 100 ml of blood.
Function : These molecules play a significant role in transport of respiratory gases LIKE `O_(2)` and `CO_(2)`
RBCs are formed in the red bone marrow.
average life span is of 120 days
They are destroyed in spleen.
(b) Leucocytes are colourless due to the lack of haemoglobin.
They are relatively lesser in number which averages 6000-8000 `mm^(3)` of blood.
they are short lived.
they are nucleated.
On the basis of presence of granules in CYTOPLASM there are two types of WBCs : GRANULOCYTES and 2. Agranulocytes.

(c) Platelets : They are also called Thrombocytes.
They are cells fragments produced from megakaryocytes (special cells in the bone marrow).
Blood contains 1,500,00 - 3,500,00 platelets `Mm^(-3)`.
Platelets ralease a veriety of substances most of which are involved in the coagulation or clotting of blood.
A reduction in their number can lead to clotting DISORDERS which will lead to excessive loss of blood from the body.
