Part 1

Question 1

White blood cell roll

Answer 1

Fight off infection and kill bacteria

Question 2

Red blood cells job

Answer 2

Carry oxygen to living tissues and carries out co2

Question 3

Plasma

• made up of _____ + _____
• what’s its role
• what causes plasma levels to drop

Answer 3

Protein and salt
Transport blood around the body
Lack of water

Question 4

What does the right side of the heart do?

Answer 4

Pumps deoxygenated blood into the lungs

Question 5

What does the left side of the heart do?

Answer 5

Pimps oxygenated blood through the body

Question 6

Describe the process of the heart

• pulmonary
• aortic
• midral
• tricuspid

Answer 6

Pulmonary -controls blood flow from right ventricle into the pulmonary arterys

Question 7

Explain myocardial infarction

Answer 7

Blockage from coronary artery = loss of blood to myocardium = dead of tissue

Question 8

Valves job…

Answer 8

To prevent venous pooling

Question 9

Electrical activity of the heart

Answer 9

Look at spreadsheet long process

Question 10

Systole and diastole

Answer 10

Systole- ventricular contraction working phase

Diastole-reaction phase 70%

Question 11

Sympathetic and parasympathetic nerves roles

Answer 11

Sympathetic- causes heart rate to increase

Parasympathetic - causes heart rate to decrease

Question 12

What nerves make up the ventricles and separately the atria

Answer 12

Ventricles- sympathetic

Atria- both : sympathetic and parasympathetic

Question 13

Normal heart rate
Bradycardia
Tachycardia

Answer 13

Normal heart rate 50-100
Bradycardia below 60
Tachycardia 100+

Question 14

Blood pressure

Answer 14

A measure of the forced blood against the arterial walls

Question 15

Blood pressure
Systolic
Diastolic

Answer 15

Systolic - a measure of the aorta during the systole

Diastolic- a measure of the aorta during diastole

Question 16

Normal blood pressure

High blood pressure

Answer 16

Normal blood pressure 120/80

High blood pressure S= 140 or D= 90

Question 17

Measuring the work of the heart

B.E.S.T.C

Answer 17

Stroke volume
Ejection fraction 
Cardiac output
Blood pressure 
Total peripheral resistance

Question 18

Stroke volume

Answer 18

The volume of blood being ejected from the left ventricle during systole

Question 19

Ejection fraction is…

Answer 19

How much blood in the ventricle was actually pumped out

Question 20

Cardiac output equation

Answer 20

Heart rate X stroke volume = cardio output

Question 21

Blood pressure equation

Answer 21

Cardiac output X total peripheral resistance = blood pressure

Question 22

2 ways blood pressure medication can help

Answer 22

Lower heart rate

Decrease the resistance in the vascularise

Question 23

Total pertinence resistance means

Answer 23

A measurement of how easily blood flows from arteliroes into the capillaries

Question 24

Vo2 Mac define

Answer 24

The highest amount of oxygen that the body can use to generate aerobicly

Question 25

Improve vo2 max - 3 points

Answer 25

Improving cardiac output Improve the ability of skeletal muscle to utilise oxygen Improve oxygen carrying capacity in the bloody

Question 26

During exercise4 points

Answer 26

Increase in cardiac output Increase in stroke volume Increase in heart rate Increase in demand by working muscles

Question 27

During workout 4 points

Answer 27

Levelling on the heart rate - steady state Increase in systolic blood pressure Decrease / no change in diastolic blood pressure Decrease in total peripheral resistance

Question 28

The heart effects of cv training

Answer 28

Increase in weight and volume of the heart Increase size in left ventricle and left wall Improved stroke volume Reduced heart rate

Question 29

What do playlets do?

Answer 29

Clot blood
