Q

Describe how the heart pumps blood around the body

A

Oxygenated blood enters the left atrium through the pulmonary veins. The left atrium contracts, pushing blood through the bicuspid valve into the left ventricle. The left ventricle then contracts forcing the blood through the semi lunar valve into the aorta to the muscles.
When the de oxygenated blood returns, it enters through the vena cava into the right atrium. This process then follows the same for the left side until it exits out through the pulmonary artery.

Q

What are the adaptions of the arteries which make it good at its job?

A

They have thick muscular walls to allow them to carry blood flowing at high pressure away from the heart.

Q

How veins adapted to be good at their job?

A

They carry blood at low pressure towards the heart so they have thinner walls.

Q

What happens to your blood vessels when you exercise?

A
  • Your arteries widen to stop blood pressure from getting to high
  • Blood vessels in the muscles widen(vasodilation)
  • Blood vessels in inactive organs narrow to divert blood towards the active muscles (vasodilation)
  • Blood is shunted closer to the skin to cool down.

A

Closing a joint e.g bending your leg

38
Q

What is extension?

A

Opening a joint e.g straightening your leg

39
Q

A

Moving a limb away from the centre of your body

41
Q

What is Rotation?

A

Clockwise or anti clockwise movement

42
Q

Q

What is the tibialis anterior?

A

The muscle at the front of the calf which moves the ankle

48
Q

What are deltoids?

A

Muscle at the shoulder

49
Q

What is an agonist?

A

The muscle that contracts to produce a movement

50
Q

What is the antagonist?

A

The muscle that relaxes during a movement

51
Q

What are slow twitch muscles best suited for?

A

Low intensity aerobic work as they can be used for a ling time without fatiguing

52
Q

What are fast twitch muscles best suited for?

A

high intensity anaerobic exercise which require greater force for a short amount of time as they fatigue quickly

53
Q

When does your body use aerobic respiration?

A

When your body is keeping up with the oxygen demand of the cells

54
Q

What are the short term affects of exercise

A
  • Increases body temperature
  • lactic acid build up
  • muscle fatigue
  • increased oxygen debt
  • Breathing rate and depth increases
  • Heart rate increases
  • stoke volume increases
  • increased cardiac output
55
Q

Long term effects of exercise

A
  • Muscles increase in size and increased strength
  • increased muscular endurance
  • `Denser bones-increased strength
  • heart gets bigger and stronger
  • Increased resting stroke volume and maximum cardiac output
  • Larger lung capacity
  • Lower blood pressure
  • more red blood cells and capillaries in the muscles
56
Q

What is the function of cartilage?

A

acts as a cushion between bones to prevent rubbing.

57
Q

What is the name of the fluid filled bag in a synovial joint which helps to reduce friction?

A

bursae

Q

How do you calculate cardiac output?

A

A

Muscles attached to the skeleton and are under your control. They help to move the body.

Q

What are involuntary muscles?

Q

Where is the Gluteus maximus located and give an example of when it is used.

A

Your arse

Extension of the leg at the hip, e.g. pushing the body forward when running.

65
Q

Where are the deltoids located and give an example of when they are used.

A

They wrap around your shoulder.

Flexion, extension, abduction or circumduction at the shoulder. E.g. during front crawl when swimming.

66
Q

Where are the latissimus dorsi located and give an example of when it is used.

A

They stretch from the back of your ribcage round to the side where it meets your external objiques.
Extension, adduction or rotation at the shoulder, e.g. during butterfly when swimming.

67
Q

Where are the External obliques located and give an example of when it is used.

A

Stretching from under your arm down the side of your rib cage, along side your latissimus dorsi on our back.
Rotation or flexion at the waist, e.g. preparing to throw a discus.

What do tendons do?

A

connect a muscle to a bone

70
