Create an India
where no one suffers or dies for want of
blood |
Blood:consists of plasma, blood cells
and platelets It is primarily a medium for the
carriage of oxygen, nutrient materials, hormones and anti-infective agents
(i.e. antibodies) to the tissues and for the removal of CO2 and
other waste products from the tissue and t he elimination from their
body.
The almost ubiquitous
distribution of blood in the body and it's unique chemical characteristics
make it the most efficient transport system.
Plasma: plasma protein, exert an osmotic pressure, which
influence the exchange of fluids between blood and tissues.
Platelets: along with plasma contains all the factors required
for clotting. Thus loss of blood from injury is reduced by inherent
properties of Blood itself.The average life of platelets is 8-days whether
we donate it or not. This will die in 8-days. |
Bloodcells: There are two types of blood cell
namely:
- Red Blood Cells(RBC)
- White Blood Cells (WBC)
Red Blood cells :
RBC are
non-nucleated bi-concave discs. The colour of blood is due to the presence
of RBC. RBC consists of an elastic framework in which haemoglobin is
deposited.
The body
produces between 20,00,000 and 1,00,00,000 new RBC each second. As RBC
carries oxygen, the concentration of O2 is lower when their
supply falls below normal. However, the defficienct stimulates the red
bone marrow to produce excess supply of new RBC. The additional cell amake
up for blood loss
The
average life span of RBC is 120 days. After that time,RBS starts losing
it's ability to transport O2. Thus you do not loose blood after
donation as on the normal course your RBC are destroyed after every 120
days. Your body will replenish the RBC count.
