Bonjour!
Blood : It is a red-coloured sticky, alkaline, slightly saltish in taste, heavier than water, fluid connective tissue.
Components of Blood : It is composed of a watery fluid, called plasma and floating cells called corpuscles.
(1) Plasma : It is slightly alkaline non-living intercellular substance which constitutes about 55% of the blood.
Major constituent of plasma is water that forms about 90% of it. The remaining 10% of plasma is made up of proteins, salts, hormones and other materials meant for transportation in the body such as digested food, gases, excretory products etc.
(2) Corpuscles : These are wandering and non-dividing cells that form about 45% of the blood.
These are of three types:
(i) RBCs i.e., Red Blood Corpuscles or Erythrocytes.
(ii) WBCs i.e., White Blood Corpuscles or Leucocytes.
(iii) Blood Platelets or Thrombocytes.
(i) Erythrocytes or RBCs : These are the most abundant corpuscles. They have a red-coloured respiratory pigment called haemoglobin that helps in the transportation of oxygen.
(ii) Leucocytes or WBCs : These cells protect the body against diseases by engulfing bacteria and other foreign particles (phagocytosis) and are hence called ‘soldiers of the body’. They also provide resistance
against diseases by producing antibodies.
(iii) Thrombocytes or Blood platelets : They help in the clotting of blood.
Hope this helps...:)

Blood is a fluid connective tissue as its name suggests connective tissue involves many components such as plasma,erythrocytes,platelets,white blood cells..et
RBC- Erythrocytes main function is to carry oxygen and it can be done with the presence of Haemoglobin in blood as it has special carrying capacity of transferring gases
WBC- leucocytes are variable in number and they are phagocytic in nature and are mainly produced in spleen,thymus gland and in some lymph nodes
