Unit 3 The circulatory system

Slide 1 - Tekstslide

3.1 Blood
Blood transports everything your body need 
              (heat, nutrients, oxygen, waste products)
Blood contains:
- blood plasma (Proteins- fibrinogen for clotting blood,
         water,                    carbon dioxide
         oxygen                  waste products

Slide 2 - Tekstslide

Red blood cells
small round discs, 
no nucleus
red pigment: haemoglobin absorb and release oxygen

Slide 3 - Tekstslide

white blood cells
do not have a fixed shape
do have a nucleus
destroy pathogens


Slide 4 - Tekstslide

fragments of cells that have broken up
- Clotting when the blood is outside the vessels
Trombosis- clottering of blood in the vessel

Slide 5 - Tekstslide

Slide 6 - Video

3.2 Blood circulation

Slide 7 - Tekstslide

Slide 8 - Tekstslide

Pulmonary circulation
(absorb 02 / release CO2)
Pulmonary circulation
Right side heart
Left side heart

Slide 9 - Tekstslide

systemic circulation
Release O2 to every living cell (respiration)
absorb CO2

Left side heart
- every organ
right side heart

Slide 10 - Tekstslide

Resperatory system and Circulatory system

Slide 11 - Tekstslide

3.4 Blood vessels (later 3.3)
3 types of blood vessels
arterie, capillarie, vein

Slide 12 - Tekstslide

From heart to organs
(red) transport O2
walls are: 
    - thick, firm, elastic
High blood pressure 

Slide 13 - Tekstslide

Release O2 into organs
Absorb Co2 into bloodstream

- one cell layer tick walls
- white bloodcells can go between the cells into the tissue

Slide 14 - Tekstslide

Slide 15 - Video

Transport CO2 from organs to the heart
- low bloodpressure
       thinner, less elastic
Includes valves
- The blood can flow in 1 direction

Slide 16 - Tekstslide

3.3 The heart

Slide 17 - Tekstslide

the heart is part of the systemic circulation.
It needs O2 (respiration) the coronary arteries provide O2 to the heart. 
The coronary veins brings CO2 back to the heart

Slide 18 - Tekstslide

the heart 

Slide 19 - Tekstslide

coronary artery, capillaries, coronary vein

Slide 20 - Tekstslide

pulmonary circulation /septum,  / systemic circulation

Slide 21 - Tekstslide


Slide 22 - Tekstslide

Slide 23 - Tekstslide

Cardiac cycle - 70 times a minute= heart rate 

Slide 24 - Tekstslide
