Q

How does blood regulate body’s temperature?

A

Absorbing heat produced by working muscles, if we didn’t have this we would quite literally fry from the inside out, then releasing it through skin (sweat) and lungs (breathing)

Q

What are white blood cells know as?

A

Fighters

22
Q

What do white blood cells do?

A

Move to sites of infection where they fight and destroy bacteria and other foreign invaders- protect the body against infection

23
Q

What does Arteries do?

A

Carry blood AWAY from the heart

24
Q

What are arteries made of?

A

Thick elastic walls, made of smoot msucle fibres

25
Q

Why is blood pushed through arteries in surges?

A

Because of the pressure cause by the beating of the heart

26
Q

What do capillaries do?

A

Form networks throughout the body’s tissue

27
Q

What are capillaries made of? Why?

A

Thin walls, to allow oxygen and nutrients to pass thought and carbon dioxide and other wasted to be passed out

28
Q

What do veins do?

A

Carry blood TO the heart

29
Q

What are veins made of?

A

Thin and elastic walls

30
Q

Why is there less pressure in the veins compared to the arteries?

A

Because the veins are further away from the heart so therefore not under the influence of the pumping of the heart

31
Q

What does the heart do?

A

A pump that pushes blood around the body

32
Q

What is the heart made of?

A

The cardiac muscles

33
Q

How many chambers are there in the heart

A

4

34
Q

Name the 4 chambers of the heart

A

Right Atrium, Right Ventricle, Left Atrium and Left Ventricle

35
Q

What does systole mean

A

Contraction phase of atrium and ventricles- pushes blood out

36
Q

What does diastole mean?

A

Relaxation phase of atrium and ventricles- fills with blood

37
Q

What is deoxygenated blood?

A

Blood that returns to the heart with very little oxygen and lots of waste products from respiration

38
Q

How does deoxygenated blood get to heart?

A

Through the veins

39
Q

What happens to deoxygenated blood after it comes back to the heart?

A

The heart pumps the deoxygenated blood through the pulmonary artery to the lungs so it can be oxygenated

40
Q

What is oxygenated blood?

A

Blood that is returned to the heart from the lungs fully oxygenated and ready to be pumped through out the whole body

41
Q

How does oxygenated blood return to the heart?

A

The pulmonary veins

42
Q

What happens to the oxygenated blood after it reaches the heart?

A

Leaves the heart through the aorta and is pumped to the rest of the body

43
Q

What does the superior vena cava do?

A

Receives deoxygenated blood from the upper body.and into the right atrium

44
Q

What does the right atrium do?

A

Receives deoxygenated blood form the inferior and superior vena cava passing it to the right ventricle

45
Q

What does the right ventricle do?

A

Receives deoxygenated blood from the right atrium and pumps through the pulmonary artery

46
Q

What does the pulmonary artery do?

A

Receives deoxygenated blood from the right ventricle and delivers it to the the lungs

47
Q

What does the aorta do?

A

Receives oxygenated blood from the left ventricle then pumps it to the rest of the body

48
Q

What does the pulmonary veins do?

A

Receives oxygenated blood from the lungs and passes it through to the left atrium

49
Q

What does the left atrium do?

A

Receives oxygenated blood from the pulmonary veins and into the left ventricle

50
Q

What does the left ventricles do?

A

Receives oxygenated blood from the left atrium and pumps it through to the aorta

51
Q

What does the Inferior Vena Cava do?

A

Receives deoxygenated blood from the lower body and pumps it into the right atrium
