2
Q
Arguments for doping in sport
A
- reduces the health risk - medical facilities to make sure its done safe
- reduces risk of long term injury

A
White blood cells
red blood cells
plasma
platelets
5
Q
Expiration
A
BREATHING OUT
- intercostal and diaphragm muscles relax as the ribs drop down
- space inside the lungs decrease and air pressure increases
- occurs until air pressure exceeds the pressure outside the body and the air is exhaled or expired
6
Q
Inspiration
A
BREATHING IN
- intercostal muscles of the diaphragm contract downwards
- ribs move upwards and outwards
- increased space within the lungs/thoracic cavity
- causes pressure in the lungs to decrease
- gasses always move from an area of higher pressure to lower pressure
- results in air quickly moving into the lungs
7
Q
Thermoregulation
A
Process of maintaining an internal temperature within a tolerable range.
8
Q
Vasoconstriction
A
narrowing of blood vessels
9
Q
Vasodilation
A
widening of blood vessels
10
Q
Blood flow through the heart
A
superior/inferior vena cava right atrium tricuspid valve right ventricle pulmonary artery lungs pulmonary vein left atrium bicuspid valve left ventricle aorta
11
Q
gaseous exchange lungs
A
- oxygen travels down the airways to the bronchs, bronchiole and bronchioles then to the alveoli
- alveoli are air sacks surrounded by capillaries
- the deoxygenated blood goes to the capillaries and diffusion occurs
- capillaries gains oxygen and the alveoli gains carbon dioxide
- then the oxygenated blood is carried by the from the capillaries to heart via the veins
