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

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 

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

Which one is the biggest part of blood?

1. Red blood cells
2. White blood cells
3. Plasma
4. Platelets

What is the name of part S

1. Red blood cell
2. White blood cell
3. Blood plasma
4. Platelet

Which blood cells produce antibodies?

1. Phagocytes
2. Lymphocytes
3. Red blood cells
4. Platelets

Were do the red blood cells develop?

1. In the bone marrow
2. In your lungs, when it takes oxygon
3. In your heart
4. In your blood capillaries

What type of cell is specialised to transport oxygen?

1. red blood cell
2. white blood cell
3. bone cell
4. nerve cell

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

1. red blood cell
2. white blood cell
3. bone cell
4. nerve cell

Which mineral is needed for making our red blood cells?

1. calcium
2. iron
3. sodium
