61
What is a Synovial Joint?
Synovial joints (or freely movable joints) are the most common types of joint and are usually found in the limbs. They are characterised by a fluid filled space between cartilage pads at the end of bones.
62
What is a Synovial Membrane?
Secrete synovial fluid.
63
What is a Synovial Fluid?
Lubricates the joint and is in the joint cavity.
64

Prevents friction between two (or more) bones.
65
What is a Joint Capsule?
Tough fibrous tissue that surrounds the joint and is supported by ligaments.
66
What is Cartilage?
Covers the end of the bones, providing a smooth, friction free surface. Cartilage acts as a shock absorber.
67
What is a Bursa Sack?
A sack of fluid that sits between your muscles/tendons and your bone to prevent friction.
68
Draw a diagram of a synovial joint.
``` (See Figure 3) Should contain: Synovial FLuid Synocial Membrane Joint cap Ligament Bursa sac Cartilage ```
69
Define Antagonistic Pairs
Muscles work in pairs. As one shortens, the other lengthens.
70
What are the 2 types of contractions?
Isotonic | Isometric
71
What is an isotonic contraction?
A Contraction when the muscles/limbs are moving, this means one muscle is lengthening and one is shortening.
72
What is a concentric contraction?
The muscles shorten.
73
What is an eccentric contraction?
The muscles lengthen.
74
What is an isometric contraction?
A Contraction where the muscles/limbs are not moving.
75
What happens in the nasal cavity?
Air is warmed, filtered and moistened.
76
Describe the pathway of air.
Air... Enters through the nasal cavity (or mouth) Passes through the trachea Beaches into one of the two bronchi Passes through one of many bronchioles Enters one of the 600 million alveoli where gas exchange occurs
77
What happens in the alveoli during inhalation?
There is a high concentration of oxygen in the alveoli, there is a low concentration of oxygen in the capillaries and thus oxygen diffuses into the blood.
78
What happens in the alveoli during exhalation?
There is a low concentration of carbon dioxide in the alveoli, there is a high concentration of carbon dioxide in the capillaries and thus oxygen diffuses out of the blood.
79
How does blood carry oxygen.
Oxygen connects to haemoglobin in the red blood cells forming oxyhemoglobin.
80
How are alveoli specialised to be good at their jobs? | 5
- Large Surface area - Thin Membrane (1 Cell thick) - Short Diffusion Pathway - Layer of Moisture - Rich Blood Supply
81
What happens to your lungs when you inhale?
The lung cavity increases so that air rushes in due to pressure difference.
82
How does your lung cavity increase at rest? | Inhalation
Intercostal muscles contract, this expands the ribcage. | Diaphragm contracts, pulling downwards to expand the chest volume.
83
How does your lung cavity decrease at rest? | Exhalation
Intercostal muscles relax, this causes the ribcage to drop inwards and downwards. Diaphragm relaxes, moving upwards, decreasing the chest volume.
84
What helps your lung cavity increase during sport? | Inhalation
Pectorals assist the intercostal muscles | Sternocleidomastoid pulls the sternum down to increase chest cavity.
85
What helps your lung cavity decrease during sport? | Exhalation
Abdominals pull down the ribcage with speed to get the largest quantity of carbon dioxide out.
86
Why is it important to breath harder when exercising?
Because you need more oxygen getting to your muscles which are working harder and you need less carbon dioxide in your lungs (taking up air pressure).
87
Define Tidal Volume
The volume of air breathed in or out during normal breathing and at rest.
88
Define Expiratory Reserve Volume
The additional air that can be forcibly exhaled after the exhalation of a normal tidal volume.
89
What does ERV stand for?
Expiratory Reserve Volume
90
What does IRV stand for?
Inspiratory Reserve Volume
91
Define Inspiratory Reserve Volume
The additional air that can be forcibly inhaled after the inspiration of a normal tidal volume.
92
Residual Volume
The amount of air that remains after a maximum expiration.
93
What happens to the different lung volumes during exercise?
Tidal Volume - Increases ERV - Stays the same IRV - Stays the same Residual Volume - Stays the same
94
What is the function of an artery?
Takes blood away from the heart.
95
What is the function of an vein?
Takes blood to the heart.
96
What is the function of an capillary?
Takes blood deep into the organs and muscles.
97
What kind of blood do arteries carry (and what is the exception)?
Oxygenated | except the pulmonary artery
98
What kind of blood do veins carry (and what is the exception)?
Deoxygenated | except the pulmonary vein
99
How are arteries specialised to complete their function?
-a thick outer wall -a thick layer of elastic muscle -a narrow lumen This allows them to deal with high pressure. (See Figure 4)
100
How are veins specialised to complete their function?
-a large lumen to deal with the high quantity of blood -have valves to prevent backlog due to low pressure (See Figure 4)
101
How are capillaries specialised to complete their function?
-only one cell thick for easy diffusion -very narrow so it can go deep into the muscle (only one red blood cell fits) (See Figure 4)
102
Define Vasoconstriction
The muscular walls construct to stem the flow of blood through the artery (Gets tighter and smaller)
103
Define Vasodilation
The muscular walls dilate to allow blood to flow more freely through the artery (Gets wider and bigger)
104
Define Hypothermia
When the body temperature drops too far (too cold)
105
Define Hyperthermia
When the body temperature increases too much (too hot)
106
Define Thermoregulation
The maintenance of a constant internal body temperature
107
Name the four heart chambers
Right Atrium - Left Atrium | Right Ventricle - Left Ventricle
108
Name the upper chambers of the heart
Atria | Right Atrium - Left Atrium
109
Name the lower chambers of the heart
Ventricles | Right Ventricle - Left Ventricle
110
Describe the transportation of blood starting with deoxygenated blood entering the Heart
Deoxygenated blood enters the Heart through the Vena Cava and into the Right Atrium It then goes through the Tricuspid valve to the Right Ventricle It is then pumped through the pulmonary valve and pulmonary artery to the lungs Blood returns to the Heart through the pulmonary vein and enters the left atrium. It is pumped into the left Ventricle by the Mitral Valve It is the pumped out to the body through Aortic valve and the Aorta
111
Name the 4 valves
Tricuspid Valve Pulmonary Valve Mitral Valve Aortic Valve
112
Name the 4 largest blood vessels in and out of the heart
Vena Cava Pulmonary Artery Pulmonary Vein Aorta
113
Define Systole
Heart ventricles contract and pump blood to the arteries
114
Define Diastole
Heart ventricles relax and the heart fills with blood
115
What type of blood does the right side of the heart pump?
Deoxygenated
116
What type of blood does the left side of the heart pump?
Oxygenated
117
Define Stroke Volume
Volume of Blood pumped out of the Heart with each beat (ml)
118
Define Heart Rate
The amount of times your Heart beats per min (bpm)
119
Define Cardiac Output
This is the volume of blood pumped by the Heart per minute (ml/min)
120
What is the equation for Cardiac Output?
Stroke Volume X Heart Rate = Cardiac Output
