Two features of alveoli which make them an effective area for gas exchange
Moist thin walls, lots of tiny blood vessels called capillaries
Systole in the cardiac cycle
Systole occurs when the heart contracts to pump blood out.
Diastole in the cardiac cycle
Diastole occurs when the heart relaxes after contraction.
Equation for aerobic respiration
glucose + oxygen → carbon dioxide + water + energy
Equation for anaerobic respiration
glucose --> lactic acid + energy
Immediate effect of exercise timeframe
During exercise
3 immediate effects of exercise
EPOC, Blood pressure increases, heart rate increases
Short-Term effect of exercise timeframe
24-36 hrs
3 short-term effects of exercise
DOMS, Fatigue, Nausea
Long-term effects of exercise timeframe
Months and years
Long-term effects of exercise
Body shape change, improvements in fitness, hypertrophy
How the short-term effects of vigorous exercise can be limited by having a massage
reduces inflammation of the tender area and increases blood flow, so increasing oxygen delivery to the muscles and the removal of lactic acid
