The circulatory system: basics 2
1. Read EVERYTHING!

2. answer the questions. 

3. Take notes and write down the blue words!

Slide 1 - Diapositive

Circulation
The human circulatory system:
 heart + blood vessels

The path taken through the body by the blood is called circulation.

Closed circulatory system: Most blood remains inside the blood vessels during transport

Slide 2 - Diapositive

Circulation
-Red blood indicates blood 
  with a lot of oxygen
-Blue blood indicates blood 
  with a lot of carbondioxide

(Not really blue in real life)


Slide 3 - Diapositive

The heart
-The heart is a double pump

-right side pumps oxygen poor
  blood into the pulmonary 
  circulation 

-left side pumps oxygen rich 
  blood into the systemic 
  circulation 
Right side
Left side

Slide 4 - Diapositive

2 different circulations:
Pulmonary circulation
Right side heart --> lungs --> left side heart


Systemic circulation
Left side heart --> rest of body --> right side heart

Humans have a double circulatory system: blood flows through the heart 2 times per circuit.

Left side
Right side

Slide 5 - Diapositive

Pulmonary circulation
Right side of the heart pumps blood to the lungs. (Oxygen poor)

Here the blood picks up Oxygen and drops of Carbon dioxide. 
--> blood goes to left side of the heart (Oxygen rich)


Right side
Left side

Slide 6 - Diapositive

Which one picks up Oxygen?
A
White blood cells
B
Red blood cells
C
Platelets

Slide 7 - Quiz

What is the pigment called that allows red blood cells to absorb Oxygen?
A
Haemoglobin
B
Thrombosis
C
Fibrinogen
D
Blood plasma

Slide 8 - Quiz

Systemic circulation
Left side of the heart pumps blood to every part of your body. (Oxygen rich)
 
Drops off: oxygen and nutrients to cells

 Picks up: Carbon dioxide and other waste products from cells

Blood goes back to right side of the heart (Oxygen poor)
 
Right side
Left side

Slide 9 - Diapositive

Which one is the shortest circulation?
A
Pulmonary
B
Systemic

Slide 10 - Quiz

Now you try!
Make exercise 8 and 9 in your paper or online book (you can reach this one from someday or magister)

If done: finish exercise 1, 2, 3, 4 and 6 from 3.1 Blood.
