Answer 1

1.heart
2.blood vessels
3. Blood

Question 2

What are the 3.blood vessles

Answer 2

1. Ateries
2. Veins
3. Capillaries

Question 3

What are the 3 main purposes of the cardiovascular system

Answer 3

1.To deliver oxygen to working muscles
2. To remove waste products E.G.carbon dioxide and lactic acid
3. Return blood to Lungs for oxygenation 

Question 4

Define atrium

Answer 4

Upper chambers that collect blood from the veins

Question 5

Define ventricles

Answer 5

Lower chambers that pump oxygenated blood through the arteries

Question 6

Whats the role of the pulmonary artery

Answer 6

To take blood away from the heart to the lungs

Question 7

Whats the role of pulmonary veins

Answer 7

To take blood to the working muscles

Question 8

Define heart rate

Answer 8

How many times your heart beats per minute ( bpm)

Question 9

Define stroke volume

Answer 9

The amount of blood pumped out of the heart her beat

Question 10

Define cardiac output

Answer 10

How much blood leave the heart per minute

Question 11

Whats the equation of cardiac output

Answer 11

Heart rate x stroke volume. Q = HR x SV

Question 12

Define systole

Answer 12

When the heart contracts and pumps blood out

Question 13

Define Diastole

Answer 13

Heart relaxes and Chambers filled with blood

Question 14

Define cardiac cycle

Answer 14

One cycle of diastole and systole

Question 15

Define recovery rate

Answer 15

How long it takes for your heart rate to get back to you resting heartbeat

Question 16

Define anticipatory rise

Answer 16

Before exercising your body releases adrenaline which increases your heart rate

Question 17

What is the first stage of the cardiac cycle 

Answer 17

Deoxygenated blood enters through the right atrium

Question 18

Whats the second stage of the cardiac cycle

Answer 18

The heart contracts and blood passes through a valve into the right ventricle

Question 19

What’s the third stage of the cardiac cycle

Answer 19

The pulmonary artery transport the deoxygenated blood to the lungs

Question 20

What’s the fourth stage of the cardiac cycle

Answer 20

Gassiest exchange takes place resulting in oxygenated blood

Question 21

What’s the fifth stage of the cardiac cycle

Answer 21

The pulmonary vein transport the oxygenated blood back to the heart were enters the left atrium

Question 22

What’s the six stage of the cardiac cycle

Answer 22

Blood passes to a valve into the left ventricle

Question 23

What’s the last stage of the cardiac cycle

Answer 23

Oxygenated blood is ejected from the heart and is transferred to the body and muscles via the aorta

Question 24

What is the role of a vein

Answer 24

To carry blood back to the heart

Question 25

What is the role of an artery

Answer 25

To carry blood away from the heart

Question 26

What is the role of the capillaries

Answer 26

To give muscles and organs oxygenated blood

Question 27

Define vasoconstriction

Answer 27

Where blood vessels get smaller through lumen and stop the blood and redirect it somewhere else

Question 28

Define vasodilation

Answer 28

When the lumen in blood vessels widen which allow more blood to flow through the muscles being used

Question 29

Define vascular shunt

Answer 29

The distribution of blood to where muscles and organs have an increased demand by vasoconstriction and vasodilation

Question 30

Define gaseous exchange

Answer 30

The process where the deoxygenated blood gets oxygenated in the lungs
