Circulatory system

unit 3

The heart pumps around 5-6 litres blood per minute through the body

1. True
2. False

How many chambers does the heart have?

1. 2
2. 4
3. 6
4. 8

This type of muscle makes your heart pump.

1. smooth muscles
2. voluntary muscles
3. involuntary muscles
4. cardiac muscles

Pictures of the heart look like this. But... how to look at it?

1. The right side on the picture is also the right side in the body
2. The right side on the picture is the left side in the body

When blood flows back to the heart, where does it go first?

1. into the valves
2. into the atria
3. into the ventricles
4. into the septum

Which valve is at the beginning of the left (big) bloodvessel?

1. Pulmonary valve
2. Bicuspid valve
3. Tricuspid valve
4. Aortic valve

Which valves are located between the atria and ventricles?

1. Tricuspid valve & bicuspid valve
2. Bicuspid valve & aortic valve
3. aortic valve & pulmonary valve
4. Pulmonary valve & tricuspid valve

The pathway of blood from the heart to the lungs, back to the heart is called the .... circulation.

Our blood circulation is a 'double circulatory system'. What does it mean?

Which part of the circulatory system prevents blood from flowing back?

1. Veins
2. Arteries
3. Valves
4. Atria

When is blood 'deoxygenated'?

1. When the concentration oxygen is low and the concentration carbon dioxide high
2. When the concentration of oxygen is high and the concentration of carbon dioxide high

Through which side of the heart flows oxygenated blood?

1. Right side
2. Left side

When blood goes to the heart, it flows into the ventricles first.

1. Correct
2. False

The systemic circulation makes sure your kidneys get oxygenated blood

1. True
2. False

Which type of bloodvessel has a thick and muscular wall?

1. Veins
2. Arteries
3. Capillaries
4. All of them

(1)____________ transports blood to the heart.
(2)____________ transports blood away from the heart

Give an explanation why arteries lay deep in the body while veins lay more on the surface

NOTE. LYMPHATIC SYSTEM

Lymphatic vessel

A bit similar to veins, how do they move the lymph, and where to?

Discuss in breakout rooms, 2 minutes

The rest of the tissue fluid flows into the lymphatic vessels

off to work

how does the body produce blood?

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

the components of blood

Made by: Thomas & Sem

V2TG

Chapter 3 par. 5

Red bloodcells (RBC)

- Red bloodcells transport oxygen

- RBC don't have a nucleus --> live up to 120 days

- RBC contain a protein called 'haemoglobin' 

iron deficiency = anemia (bloedarmoede)

White bloodcells

(WBC)

•  Are called 'lymphocytes' 
• WBC fight against Disease
• Can take on any shape 
• Lymphocytes produce anti-bodies

Blood clotting

• platelets (small cell fragments)
  
  
• important for clotting
  
  
• fibrinogen (soluble protein) --> fibrin (meshwork of threads)
  
  
• red blood cells get trapped

Bloodtypes

• RBC have antigens on the surface
• Antigens are 'markers' 
• Antigen A = bloodtype A
• Antigen B = bloodtype B
• Antigen A en B = bloodtype AB
• No antigens = bloodtype O

What will happen when u receive the wrong bloodtype?

Which antigens and anti-bodies has someone with bloodtype B?

1. Antigen A, antibodies B
2. Antigen B, antibodies A
3. No antigens, antibodies B
4. Antigen A, no anti-bodies

If u have bloodtype A, can u donate your blood to someone with bloodtype B?

1. Yes
2. No

Peter needs a bloodtransfusion. He has bloodtype AB. Which bloodtypes can he receive?

1. A
2. B
3. O
4. All of them

Which bloodtype is an universal donor?

1. O
2. AB
3. A
4. B
