20
Q

artires

A

speed : high
width : medium
pressure :slow

21
Q

capilories

A

speed :medium
width :narrrow
pressure :medium

22
Q

viens

A

speed : low
width : wide
pressure : low

23
Q

systolic pressure

A

when blood is forced into the artiresby the contractins of the left ventrical

24
Q

diastolic pressure

A

when the artries relax and because the left ventrical relaxes

25
Q

HDL (good)

A

high intensity lipoprotine is mainly made up of pritine and small amounts of fat this can help reduce cholestoral building up

26
Q

LDL (BAD)

A

low density liportice sticks to the lining of the artries

27
