Q

Describe the process of the blood with the 4 main blood vessels starting with the heart.

A

Oxygenated blood is pumped from the heart through the Aorta to parts of the body.
Deoxygenated blood returns to the heart through the Vena Cava.
The deoxygenated blood is pumped by the heart to the lungs through the Pulmonary Artery.
The lungs re-oxygenate the blood which returns to the heart through the Pulmonary Vein.
The cycle repeats.

23
Q

How do you calculate cardiac output?

A

stroke volume x heart rate

24
Q

During exercise, what happens to the heart?

A

The heart rate and the stroke volume will increase

25
Q

What benefits does the heart get from regular exercise?

A

The heart gets larger, the cardiac muscle gets thicker and stronger, the stroke volume increases which results in a lower resting heart rate.

26
Q

What is an antagonistic pair?

A

Two muscles that work together by contracting and relaxing.

27
Q

Name two pairs of antagonistic pairs.

A

biceps and triceps

hamstrings and quadriceps

28
Q

What are the 4 main functions of the skeleton?

A

Shape, movement, protection and production

29
Q

What are the two types of synovial joints?

A

Ball and socket

Hinge joint

30
Q

What are the two types of hinge joint?

A

Knee and elbow

31
Q

What are the two types of ball and socket joint?

A

Shoulder and hip

32
Q

What are the two ranges of movement in a hinge joint?

A

Flexion and extension

33
Q

What are the 5 ranges of movement in a ball and socket joint?

A

Adduction, abduction, rotation, flexion and extension.

34
Q

What is flexion?

A

The term given when the angle at the joint decreases

35
Q

What is extension?

A

The term given when the angle at the joint increases.

36
Q

What is abduction?

A

The movement of the limb away from the midline of the body.

37
Q

What is adduction?

A

The movement of a limb towards the midline of the body.

38
Q

What is rotation?

A

When the bone at a joint moves around its own axis.

39
Q

What are the 2 long term effects of exercise on the skeletal system?

A

Increased bone density and increased strength of ligaments and tendons.

40
Q

What does the term ‘voluntary’ muscle mean?

A

A muscle that works on demand.

41
Q

Can you name the 11 voluntary muscles in your body?

A

Deltoid, trapezius, latissimus dorsi, pectorals, biceps, triceps, abdominals, quadriceps, hamstrings, gluteals and gastrocnemius.

42
Q

Which muscle contracts to allow flexion of the arm at the elbow?

A

Bicep

43
Q

Which muscle contracts to allow flexion of the leg at the knee?

A

Hamstring

44
Q

Which muscle contracts to allow extension of the leg at the hip?

A

Gleuteus maximus

45
Q

A

The amount of oxygen consumed during recovery above that which would have ordinarily been consumed in the same time at rest.

50
Q

What are the long term effects of exercise on the respiratory system?

What is the definition of ‘tidal volume’?

A

During normal breathing, the total amount breathed in and out in one cycle.

52
Q

What is the definition of ‘vital capacity’?

A

The maximum you can forcibly breathe in and out.
