Pe has a lot of biology in it but it's a lot more simple, so for you to revise muscles (muscular system), bones (skeletal ststem) , heart (cardio system), lungs (gaseous exchange) will help you a lot. Also learning sports to give an example help as they always ask for that.

Learn how you would prevent injury - you could write: do a warm up by jogging at the start before a game, or a static stretch before a game. (These key words are very important, you just need to memorise these)

For your question: when picking up something for example your muscle contracts and becomes small. Muscular endurance is how long the strength lasts for.

Strength is how much weigh you can lift.

Cardiovascular endurance is how good your heart, lungs and blood vessels send oxygen to your body cells. E.g. A long distance runner has a lot of cardio vascular endurance as they can run longer.

To find the maximum heart rate your body can handle : 220 - age

Bones give either: structure, protection or to store minerals a in the bones calcium.

Gaseous exchange is the process of oxygen exchanging into carbon dioxide (and vice versa). This happens in the lungs and blood vessels which send oxygen to your body ( muscles / tissues)
