Lesson 5: Blood composition &

Blood types

Stand up! Sprint 2

All tasks divided? 

Are their any problems?

What do you have ready for the team?

What are you going to do for the team?

What is the function of blood?  

• Transports things from one part of your body to the other (oxygen, nutrients)
  
  
• -Helps protect your body from disease (immune system)

Blood composition

-5 liters in your body

-Plasma: water with chemicals 

(antibodies, hormones, sugars, vitamins)

-Blood cells 

(white, red and platelets)

Red  cells

-Carry oxygen

-No nucleus

-Filled with haemoglobin 

(binds oxygen)

Which are red blood cells?

Blood clotting

• platelets (small cell fragments)
  
  
• important for clotting
  
  
• fibrinogen (soluble protein) --> fibrin (meshwork of threads)
  
  
• red blood cells get trapped

White cells -> Fight diseases

Phagocytes

-cell eaters 

engulf or swallow pathogens

White cells -> fight diseases

Lymphocytes

- make antibodies that attack pathogens

1. they stick together

2. they dissolve them

3. they destroy the toxins they make

antibodies stay in your blood and 

make you immune to the disease
