Q

Properties of the semi lunar valves

A

Stop the backflow of blood into heart. There is a semilunar valve where the water leaves are left electrical and another where the pulmonary artery leaves the right ventricle.

Q

What are the four main functions of the cardiovascular system?

A

Deliver oxygen and nutrients to the body, remove the waste product such as carbon dioxide and lactic acid, protection against diseases and infection and to maintain body temperature

Q

The average blood pressure for an adult is 120/80mmHg. Which number is the systolic value and which number is the diastolic value?

A

First is systolic second is diastolic

17
Q

What are the two things? Blood pressure is determined by?

A

Cardiac output and resistance to the blood flow

18
Q

What causes resistance to blood flow?

A

The diameter of the blood vessels and the thickness of the blood

19
Q

What happens to the resistance of blood flow blood pressure? The person has a condition called atherosclerosis (plaque in the arteries?)

A

The resistance to blood flow will increase and so will the blood pressure

20
Q

What is heart rate?

A

The number of times the heart beats (or the ventricles pump blood out) in one minute

21
Q

What is the average resting heart rate?

A

70bmp

22
Q

What is stroke volume?

A

The amount of blood pumped out of the ventricles each time they contract

23
Q

What is the average resting stroke volume?

A

70ml

24
Q

What is cardiac output?

A

The amount of blood pumped from the heart every minute

25
Q

How can you calculate cardiac output?

A

Heart rate x stroke volume

26
Q

How to find out maximum heart rate

A

220-age

27
Q

what happens to stroke volume during exercise?

A

It increases

28
Q

What happens to cardiac output during exercise?

A

It increases

29
Q

Blood pressure during exercise what…

A

Increases

30
Q

What is the passage of air to the lungs?

A

Enters the body and is warmed as it travels through the mouth and nose. Then enters the trachea. The trachae divides into two bronchi. One bronchus enters each lung. Each Bronchus branches out into smaller tubes called bronchioles. Air travels through these bronchioles. At the end of the Bronchioles the air enters one of the many millions of alveoli where Gaseous exchange takes place
