carry blood away from the heart. All arteries carry oxygenated blood except for the pulmonary arteries. Their thick, muscular walls allow them to carry blood flowing at high pressure
1 of 29
veins
carry blood towards the heart. all veins carry deoxygenated blood, except for the pulmonary vein. they carry blood at a low pressure, so they have thinner walls and less muscle than arteries
2 of 29
capillaries
carry blood through the body to exchange
3 of 29
What is the trachea supported by?
cartilage - 15 to 20 rings
4 of 29
what is the function of alveoli?
to perform gas exchange and so oxygen can get into the bloodstream
5 of 29
tidal volume
the amount you breathe in and out in one normal breath
6 of 29
respiratory rate
how many breaths you take per minute
7 of 29
minute volume
the volume of air you breathe in in one minute
8 of 29
vital capacity
the maximum volume of air you can breathe out after breathing in as much as you can
9 of 29
residual volume
the amount of air left in your lungs after you've breathed out as hard as you can
10 of 29
aerobic respiration eq.
glucose + oxygen → (energy) carbon dioxide + water
11 of 29
anaerobic respiration eq.
glucose → (energy) lactic acid
12 of 29
functions of the circulatory system
transport, controlling the temperature and the clotting of wounds
13 of 29
what is an average blood pressure
120/80
14 of 29
what is the systolic blood pressure
when your heart rests
15 of 29
what is the diastolic blood pressure
when your heart beats
16 of 29
why are arteries thicker?
because they hold a high pressure of blood
17 of 29
why are veins thinner than arteries?
they hold a lower pressure of blood
18 of 29
what valve is on the left-side of the heart?
tricuspid valve
19 of 29
what valve is on the right-side of the heart?
bicuspid valve
20 of 29
what divides the two sides of the heart?
the septum
21 of 29
what is the function of the valve
to stop the backflow of blood
22 of 29
how do you work out the maximum heart rate?
220 - age
23 of 29
stroke volume
the amount of blood pumped out of the left ventricle per beat
24 of 29

what are the long term effects of exercise on the muscular and the skeletal system?
muscle hypertrophy, increased bone density, stronger ligaments & tendons
28 of 29
what are the long term effects of exercise on the cardiac and respiratory system?
Bigger/stronger heart, larger lung capacity, lower blood pressure, more capillaries in the muscles, more red blood cells
