Blood pressure
The force exerted by the blood on the walls of the arteries
3 of 20
Systolic BP
Maximum pressure in the arteries when the heart contracts
4 of 20
Diastolic BP
Maximum pressure in the arteries when the heart relaxes
5 of 20
What's our average BP?
120/80

Aerobic respiration
Using O2 + glucose to produce energy
7 of 20
Anaerobic respiration
When the demand of O2 is too high and the body cant supply enough O2 to make energy, the body has to use stored glycogen to produce energy. This produced lactic acid.

Stroke volume
Volume of blood pumped out of the heart every beat
9 of 20
Cardiac output (Q)
(Q=HRxSV)
Amount of blood pumped out of the heart every minute
10 of 20
Heart rate
Amount of heart beats per minute
11 of 20
Venous return
Volume of blood returning to the right atrium
12 of 20
Ejection fraction
Percentage of blood actually pumped out of the LV each beat
13 of 20
End systolic volume (ESV)
Amount of blood in the LV at the end of contraction
14 of 20
End diastolic volume (EDV)
Amount of blood in the LV at the end up filling

What is bradycardia?
RHR of below 80bpm
16 of 20
Cardiac hypertrophy
where the ventricle wall gets larger or thickens as a result of exercise. So the heart has a stronger pump, and can pump more O2 around the body.

Sedentary lifestyle
one with no or irregular physical activity and an excessive amount of daily sitting

Cholesterol 2 types
HDL - high density lipoproteins - good fats, fruit, veg, whole grain
LDL - low density lipoproteins - bad fats - causes build up in arteries, fatty fried foods.
