Slide 1 - Slide

Blood transports many different substances throughout the body.
When do these substance go IN or OUT of the blood?

Slide 2 - Drag question

The heart 

Slide 3 - Slide

Location of the heart

Slide 4 - Slide

Pulmonary vein
Aorta
Pulmonary artery
Vena cava

Slide 5 - Drag question

When is blood 'deoxygenated' ?
A
when the concentration oxygen is low
B
when the concentration oxygen is high

Slide 6 - Quiz

Structure of the heart
The heart is a hollow muscle.

Coronary arteries (red arteries) supply Oxygen rich blood + nutrients to the heart

Coronary veins (blue veins) carry Carbon dioxide + waste products away from the heart. 

Slide 7 - Slide

semilunar valves
right ventricle
septum
left ventricle
heart valves
left atrium

Slide 8 - Drag question

Which artery brings blood to the heart itself?
A
Aorta
B
Coronary arteries
C
Coronary veins

Slide 9 - Quiz

The heart has four chambers:
- Left atrium
- Right atrium
- Left ventricle
- Right ventricle

Blood always enters the heart via the atria.

Septum: a wall separating the left and right side of the heart.

Slide 10 - Slide

Bloodflow
*Superior vena cava: Oxygen-poor blood from head + arms to right atrium

*Inferior vena cava: Oxygen-poor blood from torso + legs to right atrium

*Pulmonary veins: Oxygen-rich blood from lungs to left atrium 

*Aorta: Pumps Oxygen-rich blood to rest of the body



Slide 11 - Slide

Slide 12 - Slide

The heart pumps oxygen rich blood into the?
A
Superior vena cava
B
Pulmonary arteries
C
Aorta
D
Aorta and pulmonary arteries

Slide 13 - Quiz

When blood flows back to the heart where does it go first?
A
Into the valves
B
Into the atria
C
Into the ventricles
D
Into the septum

Slide 14 - Quiz

Heart valves
*Atria + ventricles separated by Left and right side valves.

*Semilunar valves keep blood from flowing back into ventricles.

As you can see, a valve only opens in one direction

Slide 15 - Slide

Which part of the circulatory system prevents blood from flowing back?
A
Veins
B
Arteries
C
Valves
D
Atria

Slide 16 - Quiz

Slide 17 - Link

The heart part 2

Slide 18 - Slide

cardiac cycle
- atria contract, blood flows into 
   ventricles (ventricles relaxed)

- ventricles contract, blood 
   flows into aorta and pulmonary 
   artery (atria relaxed)

- Heart relaxes, blood flows 
   into atria 

Slide 19 - Slide

Put the texts underneath the corresponding picture.
Cardiac pause - heart fills with blood
Atria contract
Cardiac pause - heart fills even more with blood
Ventricles contract
Blood flows into arteries

Slide 20 - Drag question

Pulmonary (lung) circulation:

Heart - lungs - heart
Systemic (body)

Heart - body - heart
