Cardiovascular System

Question 1

What are the three parts of the cardiovascular system

Answer 1

• heart
• blood
• blood vessels

Question 2

What is the role of the Heart?

Answer 2

Pump blood around the body

Question 3

What is the role of the blood?

Answer 3

• Carry oxygen and nutrients around the body

- take away waste products

Question 4

What is the role of the blood vessels?

Answer 4

To transport the blood around the body

Question 5

Equation for pulse pressure =

Answer 5

Systolic - diastolic

Question 6

Equation for cardiac output =

Answer 6

Stroke volume X Heart rate

Question 7

Two types of blood pressure:

Answer 7

• systolic

- diastolic

Question 8

Define Systolic

Answer 8

Maximum pressure in the arteries

Question 9

Define diastolic

Answer 9

Pressure during the relaxation phase, between heartbeats

Question 10

Which blood pressure changes when exercising?

Answer 10

Systolic

Question 11

Short term effects of exercise on the cardiovascular system:

Answer 11

• increased blood pressure

- increase heart rate

Question 12

What does it mean by increased heart rate

Answer 12

When exercising heart rate increased to supply more oxygen to the working muscles

Question 13

What does it mean by increased blood pressure

Answer 13

When exercising more blood is being pumped around the body meaning there is more pressure in the blood vessels

Question 14

Long term effects of regular exercise on the cardiovascular system

Answer 14

• decreased resting heart rate
• heart recovery rate
• increased stroke volume
• increased cardiac output
• decrees blood pressure

Question 15

How does your resting heart rate decrease

Answer 15

Cardiac Hypertrophy

The heart gets stronger and beats more blood per pump, meaning it can beat less.

Question 16

Stroke volume =

Answer 16

The amount of of blood pumped by the heart per beat

Question 17

Definition of cardiac output:

Answer 17

The amount of blood ejected by the heart each minute

Question 18

How does your blood pressure decrease

Answer 18

• blood vessels are more flexible

- increased number of capillaries

Question 19

What causes Coronary Heart Disease

Answer 19

• hereditary
• narrow arteries
• high blood pressure
• smoking

Question 20

What is cholesterol

Answer 20

A fatty substance carried in blood by lipo proteins

Question 21

What is high density cholesterol

Answer 21

‘Good cholesterol’

- contains more protein than fat

Question 22

What types of food contain high density cholesterol

Answer 22

• fruit, vegetables, while grain

Question 23

What is low density cholesterol

Answer 23

Builds up a plaque which restricts flow through arteries

This increased blood pressure

Question 24

What is a recreational drugs

Answer 24

Not a performing enhancing drug

Question 25

Give two example of recreational drugs

Answer 25

Smoking

Alcohol

Question 26

What does smoking do

Answer 26

• Nicotine releases adrenaline

- Increased heart rate and - Increased blood pressure
