Q

What happens during inspiration?

A

lungs create a vacuum
intercostal muscles contract pulling ribs out and up
diaphragm contracts and flattens increasing chest size
so lung size can increase
lungs can expand more in exercise with sternocleidomastoid and pectorals

A

force of blood passing through arteries

25

blood pressure while the heart is relaxing

26
Q

What is a heart rate?

A

number of times your heart beats in 1 minute

70-72bpm

28
Q

what does a lower resting heart rate mean?

A

high levels of cardio-vascular endurance/ aerobic fitness

29

.protect body, stopping it from bleeding
.clump together to form scabs
.prevents infection

33
Q

What do white blood cells do?

A

produce antibodies
.destroy harmful microorganisms
.prevent infection
.made in bone marrow

34
Q

What does plasma do?

A

.transports everything
.blood cells. CO2, hormones, waste

35
Q

functions of the blood?

A

.transport nutrients and waste
.deliver oxygen to working muscles
.remove heat
.get rid of LA
.defend body against infection
.regulate blood pressure

36
Q

What is vasoconstriction?

A

a response to being too cold.
narrowing of blood vessels at the skin surface to reduce heat loss

37
Q

What is vasodilation?

A

a response to being too hot.
widening of blood vessels at the skin surface to increase heat loss

38
Q

What is vascular shunt?

A

During exercise, blood is redistributed so more goes to working muscles.
This redirection of blood flow is called vascular shunt.
