2. BLOOD
Blood is a body fluid in humans and
other animals that delivers necessary
substances such
as nutrients and oxygen to the cells and
transports metabolic waste products
away from those same cells

3. Functions
• Blood performs many important functions
within the body, including:
• Supply of oxygen to tissues (bound
to hemoglobin, which is carried in red cells)
• Supply of nutrients.
• Removal of waste such as carbon
dioxide, urea, and lactic acid

4. Functions
circulation of white blood cells, and detection
of foreign material by antibodies
• The response to a broken blood vessel, the
conversion of blood from a liquid to a
semisolid gel to stop bleeding
• Messenger functions, including the transport
of hormones and the signaling
of tissue damage
• Regulation of core body temperature
• Hydraulic functions

5. Cells
One micro liter of blood contains:
• 4.7 to 6.1 million (male)
• 4.2 to 5.4 million (female)

6. Blood
Blood contains red cells, white cells, and
platelets

8. Red cells
Red cells carry oxygen from the lungs to your
body’s tissue and take carbon dioxide back to
your lungs to be exhaled.

9. Platelets
Platelets are small, colorless cell fragments in
the blood whose main function is to interact
with clotting proteins to stop or prevent
bleeding.

10. Plasma
Plasma is a fluid, composed of about
92% water,
7% vital proteins and other clotting factors,
1% mineral salts, sugars, fats, hormones and
vitamins.
