Q

Gaseous Exchange

A

The process where oxygen from the air in the alveoli moves into the blood in the capillaries and carbon dioxide moves from the blood into the air in the alveoli.

17
Q

cardiac output

A

The volume of blood ejected from the heart in one minute
Cardiac Output =
Stroke Volume X Heart Rate

18
Q

Cardio-Respiratory System

A

When the cardiovascular system and the respiratory system work together.

19
Q

diastole

A

The phase of a heart beat when the chambers relax and fill with blood.

20
Q

heamoglobin

A

The protein found in red blood cells that transports oxygen (as oxyhaemoglobin) and carbon dioxide around the body.

21
Q

heart rate

A

The number of times your heart beats in one minute.

22
Q

antagonist

A

The muscle or group of muscles that relax to allow a movement to take place. The antagonist works in pairs with the agonist.

23
Q

agonist

A

Muscle or group responsible for the movement.

24
Q

adduction

A

Movement of a bone or limb towards

the midline of the body.

25
Q

abduction

A

Movement of a bone or limb away from the midline of the body.

26
Q

extension

A

Increase in the angle of bones at a joint.

27
Q

flexion

A

Decrease in the angle of the bones at a joint

28
Q

synovial membrane

A

produces synovial fluid

29
Q

synovial fluid

A

provides lubrication

30
Q

joint capsule

A

encloses/supports bursae (sacks of fluid) – reduce friction

31
Q

cartilage

A

prevents friction/bones rubbing together

32
Q

ligaments

A

attach bone to bone

33
Q

synovial joint

A

An area of the body where two or more bones meet (articulate) to allow a range of movements. The ends of the bones are covered in articular cartilage and are enclosed in a capsule filled with fluid.

34
Q

skeletal system

A

Skeletal system provides a framework of bones for movement, in conjunction with the muscular system.

35
Q

rotation

A

movement around an axis

36
Q

plantar flexion

A

Pointing the toes at the ankle/increasing the ankle angle

37
Q

dorsi flexion

A

Toes up at the ankle/decreasing the ankle angle.

38
Q

isotonic contraction

A

Muscle contraction that results in limb movement

39
Q

concentric contracion

A

Shortening of the muscle

40
Q

eccentric contraction

A

Lengthening of the muscle.

41
Q

hypertrophy

A

The enlargement of an organ or tissue caused by an increase in the size of its cell.

42
Q

articulating bones

A

Bones that meet at a joint to enable movement.
