2.5 the components of blood

Made by: Thomas & Sem

V2TG

Chapter 3 par. 5

what we already know about blood transport

oxygen transport from lungs to cells

carbon dioxide from cells to lungs

nutrients from intestine to cells

waste from cells to kidneys

do the assignment

on the worksheet

The different blood parts

• Plasma 55%
• Red blood cells 45%
• Platelets & white blood cells <1 %

Blood composition

-5 liters in your body

-Plasma: water with chemicals 

-Blood cells 

all the hidden pictures you have to print and hang in the classroom before hand!

assignment: information hunt

- there is information on sheets in the classroom

- you wille see questions projected on the board

- one of you will go find information 

- the other one writes down the answers

- half way through the questions you switch

how does the body produce blood?

• the bone marrow of flat bones produces bloodcells (red bone marrow)
• PLATELETS, RED AND WHITE BLOOD CELLS

Anemia (bloed armoede)

-lower amount of red blood cells

-less oxygen can be transported

-treatment -> blood transfusion

Leukemia

-blood cancer

-high number of abnormal blood cells

Red blood cells

-Carry oxygen

-No nucleus

-Filled with haemoglobin 

(binds oxygen)

Which are red blood cells?

structure haemoglobin

White blood cells

• good health
• protection
• immunity cells
• phagocytes ('eat')
• lymphocytes (antibodies)

White blood cells -> fight 

diseases

Lymphocytes

- make antibodies that attack pathogens

1. they stick together

2. they dissolve them

3. they destroy the toxins they make

your lymphocytes can make memory cells,

when the same disease enters your body they

immediately make antibodies => immunity

questions (15 minutes)

1. Which substance is the biggest part of blood?

2. Which blood cells produce antibodies? 

3.Were do the red blood cells develop?

4.What type of cell is specialised to transport oxygen?

5.What type of cell is specialised to protect our body against germs?

6.Which mineral is needed for making our red blood cells?

7.Which two types of white bloodcells do we have?

8. How do our specialized cells for protecting against germs work?

9.Which type of bloodcells are abnormal in leukemia?

10. What's wrong with your blood when you have anemia?

answers

1. plasma

2. lymphocytes

3. red bone marrow

4. red blood cells

5. white blood cells

6. iron

7. lymphocytes and fagocytes

8. they make antibodies that stick to germs (lymphocytes) and fagocytes 'eat' germs and destroy them.

9. white blood cells => more

10. too little red blood cells
