3. Blood
• Blood is considered as River of
life, Fluid of life, growth & health
• Average human has 5 litres of
blood i.e, 8% of total body weight
• It is a transporting fluid
• It carries vital substances to all

• - Oxygen-poor blood is purple red.
• Red colour comes from the several million
red cells, present in it
• pH must remain between 7.35–7.45
• Temp 38˚ c or 100.4˚ F

5. Properties Of Blood
• Blood is 5 times more viscous than
water.
• Blood is a specialized type of
connective tissue in which living
blood cells, (formed elements), are
suspended in a non living fluid matrix
called plasma.
• Cellular Part (Formed Elements)
• Non cellular part (Plasma)
