Blood is a bodily fluid that transports nutrients, oxygen, waste products, and other substances around the body. It contains plasma, red blood cells, white blood cells, and platelets. Blood vessels, including arteries, capillaries, and veins, form the circulatory system to transport blood throughout the body, with arteries carrying oxygenated blood away from the heart and veins carrying deoxygenated blood back to the heart.

2. About blood…

3. DEFINITION
 Blood is a specialised bodily fluid that
delivers necessary substances such as
nutrients and oxygen to the cells and
transports metabolic waste products
away from those same cells.

4. Substances FOUND IN BLOOD…

5. 1) PLASMA
 It is the yellowish fluid in blood that
makes up the 55% of the total blood
volume. It consists of dissolved proteins,
glucose, clotting factors, mineral ions,
hormones, CO2. In the body, plasma
serves as a medium to transport
essential substances in blood.

6. 2) RED BLOOD CELL
 The red blood cell specialised for
oxygen transport, having high
concentrations of haemoglobin in the
cytoplasm.

7. 3) WHITE BLOOD CELL
 It is the primary rule involves the body’s
immune system, protecting the body
against invading micro-organisms and
foreign particles.

8. 4) PLATELETS
 It is a particle found in the bloodstream
that binds to fibrinogen at the site of a
wound to begin the blood clotting
process.

9. About blood vessels…

10. DEFINITION
 The blood vessels are the part of the
circulatory system that transports blood
throughout the body.

11. 3 major parts of the blood
vessels…

12. 1) ARTERIES
 Arteries are blood vessels that carry
blood away from the heart. This blood is
normally oxygenated, exceptions made
for the pulmonary arteries.

13. 2) CAPILLARIES
 Capillaries are the smallest of a body's
blood vessels. It enables the actual
exchange of water and chemicals
between the blood and the tissues.

14. 3) VEINS
 In the circulatory system, veins are
blood vessels that carry blood towards
the heart.
