Structure and function of the respiratory system
Nose
Provides a warm, moist place for air to enter the body.
146
Structure and function of the respiratory system
Nasal cavity
Situated in the nose and contains hair that filters/cleans foreign obkects. Warms incoming air.
147
Structure and function of the respiratory system
Pharynx
Throat. Connects the nasal cavity and mouth to the larynx. Pathway for food and air.
148
Structure and function of the respiratory system
Larynx
Responsible for ensuring food/air go in propper channels. Contains vocal cords that vibrate to produce sound
149
Structure and function of the respiratory system
Trachea
Windpipe. Is flexible and mobile. Cilia (tinny hairs) lining the trachea expel dust and other foregin particals. The trachea divides into two bronchi.
150
Structure and function of the respiratory system
Bronchi
Each bronchus leads into the left and right lung, inside the lung, bronchi divide further into bronchioles.
151

154
Lung function
Inspiration
Breathing in. The diaphragm contracts and flattens lifting ribs outwards and upwards increasing the volume of the chest cavity. Air flows into the lungs in response to a derease in air in the lungs (High pressure to low pressure)
155
Lung function
Expiration
Breathing out. The diaphragm relaxes and moves upwards. This decreases the volume of the chest cavity which increases air pressure in the lungs. Air moves out to the atmosphere where the air pressure is lowered.
156
Exchange of gases
Internal
Blood being pumped from the heart to the rest of the body is oxygenated. Gaseous exchange occurs. The oxygen from the blood capillaries diffuse to the body tissue celss due to pressure differentials and picks up the Co2. It is a 2 way diffusion process.
157
Exchange of gases
External
This 2 way diffusion process happens when oxygen from the air and Co2 from the blood exchange. When the lungs fill with oxygen, the pressure/concentration of O2 is higher in the alveoli than in the blood. This causes the O2 to diffuse and move across into the blood. At the smae time, blood returning from the body to the lungs in hight in Co2. The Co2 diffuses witht he alveoli because of the pressure differential and is breathed out when we exhale.
158
Circulatory systerm
The main role of the circulatory system is to ensure blood flows around the body from the heart to the cells, and then returning to the heart. This process is called circulation.
159
Main components of circulation
Blood
Blood is a complex fluid circulated around the body by the puming action of the heart nourishing every part of the body
160
Main components of circulation
Heart
Muscular pump that contracts rhythmically, provides force to keep blood circulating. Heart lies in the chest cavity above the diaphragm protected by ribs and sternum.
161
Main components of circulation
Blood vessels
Arteries (red - away from heart, rich in oxygen)
Veins (blue, towards the heart, poor oxygen)
Capillaries (smallest blood vessels, echange oxygen and nutrience for waste)
162
Three main functions of blood
- Transpiration of oxygen and nutrients and removal of Co2 and waste
- Protection for the body via immune system and clot to prevent blood loss
- Regulation of body temerature and fluid content of the body tissue.
163
Plasma
Liquid, 90% of water, and is 55% of volume of blood
164
Red blood cells
Formed in bone marrow, carries O2 and Co2 around the body. Flat/disc like shaped. Contains haemoglobin and iron.
165
White blood cells
Formed in bone marrow and lymph nodes. Protect against diseases and flow to areas of infection and disease.
166
Platelets
Tiny structure made from bone marrow cells and help produce clotting substances to prevent blood loss.
167
Movement of blood in and out of the heart
1. Deoxygenated blood enters the right atrium through the superior and inferior vana cava and enters through the right vetricle via a valve.
2. Deoxygenated blood is pumped through the pulmonary artery to the lungs.
3. Gas exchange occurs. It is then pumped through the pulmonary vein to the left atrium.
4. The oxygenated blood is pumped through a valve in the left atrium and pumpes the blood all the way up to the aorta and around the body.
168
Arteries / function
Carry oxygen rich blood away from the heart.
Think strong elastic wall
Smooth muscle to withstand blood pressure
169
Veins / function

T: Type of training (What is it)
T: Time of training (how long)

Heart rate
What?
Heart rate is the number of times the heart beasts per minute
234
Immediate physiological responses to training
Heart rate
How it changes
HR increases according to the amount of intensity/effort during exercise
235
Immediate physiological responses to training
Heart rate
Why it changes during and after exercise
During - to get more oxygen to working muscles.
After - Decreases to return to pre-exercise levels
236
Immediate physiological responses to training
Ventilation Rate
What
Ventilation rate is the breathing rate (air in and out of lungs)
237
Immediate physiological responses to training
Ventilation Rate
How it changes
Rate and depth of breathing increases even before exercise in anticipation and continues to intensify as exercise starts.
238
Immediate physiological responses to training
Ventilation Rate
Why it changes
During - body requires and increase in O2 consumption to get more oxygen to working muscles.
After - Decreases to return to pre exercise levels.
239
Immediate physiological responses to training
Stroke Volume
What
Stroke volume is the amount of blood pumped out of the left ventricle during a contraction (per beat). it is measured in mL/beat.
240
Immediate physiologial responses to training
Stroke Volume
How it changes
SV increases during exercise. This in turn increases the amount of oxygen available at working muscles.
241
Immediate physiological responses to training
Stoke Volume
Why it changes during and after exercise
During - This occurs as a result of more blood returning to the heart. This provides a more forceful contraction.
After - Returns to pre exercise levels. SV should be better/higher in athletes.
242
Immediate physiological responses to training
Cardiac output
What
Cardiac ouput is the amount of blood pumped out of the heart per minute.
243
Immediate physiological responses to training
Cardiac output
How it changes
Cardiac ouput increases as ecercise demands increase
(Cardiac output = HR x SV)
244
Immediate physiological responses to training
Cardiac output
Why it changes during and after exercise
During - There is a sharp increase in cardiac output as exercise commences, and this continues to increase as workload increases in order to meet the exercising muscles demands per more oxgyen.
After - Return to pre exercise levels.
245
Immediate physiological responses to training
Lactate levels
What
Lactate is produced by the breakdown of carbohydrates and is cleared from the body by the muscles
246
Immediate physiological responses to training
Lactate levels
How it changes
Under resting conditions its clearance rate is in balance, resulting in constant levels of 1-2mmol/L.
247
Immediate physiological responses to training
Lactate levels
Why it changes during and after exercise
During - Lactate levels will increase as the body produces lactic acid to create energy for the muscles. The amount will vary depending on the intensity of exercise. High intensity exercise will create higher lactate levels.
After - It is cleared from the body and the muscles, so it is minimal in the body.

Linear motion occurs when a body and all parts connect to it travel the same distance in the same direction at the same speed.
E.g., a swimmer pushing off the wall
251
Motion - velocity and speed
Speed and velocity describes the rate at which a body moves from one location to another.

Velocity = displacement / time taken
Displacement is the movement of a body from one location to another in a particular direction. start to finish points.
