What is Blood??Blood is a liquid connective tissue that maintains

the life process by continuous circulation.Blood carries oxygen from the lungs to the rest of

the body. It also carries waste to be eliminated from the

body.Blood cells originate in Bone marrows. Bone marrow is the soft and spongy material in

the centre of the bone.

Blood contains three type of cells 1) Erythrocytes (RBC), 2) Leucocytes (WBC) and 3) Platelets suspended in a straw coloured fluid called the

Plasma.

The primary function of RBC is to transport oxygen and carbon dioxide. They are characterized by the presence of haemoglobin (Hgb), an iron containing protein.

The WBC fight against bacterial, viral, fungal and parasitic infections.

The Platelets are responsible for blood clotting.

Austrian Biologist and Physician distinguished the main blood groups in 1900.

Importance of blood donationAlmost in all serious health issues blood is donated by

people like you and me to save lives. Blood that is donated last a little more than 40 days, Then

it must be disposed of. That means we need to constantly replenish the blood so

it is there when someone needs it.

Not everyone can save a life. But you have an opportunity to, Don’t waste it!

Who can donate the blood?

Donor should be between 18-55 years of age with a weight of 50 kg or above with pulse rate, body temperature and blood pressure should be normal.

Both men and women can donate.

How much blood can be taken?Our body has 5.5 litre of blood of which only 350 ml -

450 ml of blood is taken depending upon weight of donor.

Majority of healthy adults can tolerate withdrawal of one unit of blood.

The withdrawn blood volume is restored within 24 hours and the haemoglobin and cell components are restored in 2 months.

Therefore it is safe to donate blood every three months.
