Blood circulation
par 2
Slide 1 - Tekstslide
The heart
-The heart is a double pump
-left side pumps oxygen rich
blood into the systemic
circulation
-right side pumps oxygen poor
blood into the pulmonary
circulation
Slide 2 - Tekstslide
Slide 3 - Video
Circulation
-Red blood indicates blood
with a lot of oxygen
-Blue blood indicates blood
with a lot of carbondioxide
-(notice the way the blue blood
goes: from your body
towards the heart)
Slide 4 - Tekstslide
Circulation
Pulmonary circulation
From the heart to the lungs
Systemic circulation
From the heart to every part of your body
Slide 5 - Tekstslide
Pulmonary circulation
To the lungs to pick up oxygen and drop of carbondioxide
Slide 6 - Tekstslide
Systemic circulation
To every part of your body to drop of oxygen and nutrients and pick up carbondioxide and other waste products
Slide 7 - Tekstslide
Coronary circulation
Blood circulation of the heart
-Arteries: towards the heart
muscle
-Veins: away from the heart
muscle
Slide 8 - Tekstslide
b2: circulation
-Systemic circulation:
-brings oxygen and nutrients to body cells.
-Takes away waste products from body cells.
-Oxygen-rich blood is bright red, flows through left side.
Slide 9 - Tekstslide
b2: circulation
Humans have a double circulatory system: blood flows through heart 2 per lap/circuit.
Slide 10 - Tekstslide
b2: circulation
-Pulmonary circulation:
-Takes in oxygen from the lungs.
-Releases CO2 to lungs to breathe out.
-Oxygen-poor blood is dark red, flows through the right side of the heart.
Slide 11 - Tekstslide
A double circulatory system is more efficient for taking in oxygen. Explain why only birds and mammals have this system.
Slide 12 - Open vraag
Humans do have a so called 'double circulatory system'. What does that mean?
