1

What is the circulatory system?

The circulatory system is the system that moves blood throughout the body

2

What does the circulatory system include.

The circulatory system includes the heart, blood and blood vessels

3

What carries oxygen to the cells?

Red blood cells in blood carry oxygen to the cells.

4

What happens when the body uses oxygen?

When oxygen is used by cells carbon dioxide is waste

5

What happens to the waste carbon dioxide?

The red blood cells also carry the carbon dioxide so it can leave the body

6

Is blood a solid, liquid or gas?

Blood is liquid

7

How does blood moves?

blood is pumped through a network of tubes

8

What are blood vessels?

Blood vessels are the tubes that blood flows through

9

What are the three types of blood vessels?

The three types of blood vessels are arteries, veins and capillaries

10

What are arteries?

Arteries are thick-walled blood vessels that move oxygen rich blood to the cells of the body

11

What are veins?

Veins are thinner-walled blood vessels that bring blood back to the heart and lungs so it can be enriched with more oxygen

12

What are capillaries?

Capillaries are very thin blood vessels that link arteries with veins, they are the site of oxygen diffusing from capillaries into cells and carbon dioxide diffusion from cells into capillaries

13

What is the role of the heart?

The role of the heart is to pump blood

14

How many chambers does the heart have?

The heart has four chambers

15

What are the upper chambers?

The upper chambers are the right and left atrium

16

What are the lower chambers?

The lower chambers are called the right and left ventricles

17

What is the order of blood flow through the heart?

De-oxygenated blood goes from veins into the right atrium-- to right ventricle – to lungs to get oxygen via the pulmonary artery – from lungs back to the heart via the pulmonary vein and into the left atrium – left ventricle sends oxygen rich blood to the whole body through arteries

18

What makes up the respiratory system?

The respiratory system is the lungs and a series of passages that bring oxygen to the body

19

The passages that lead from the nose down the throat and into two air tubes are called the....

bronchi

20

The bronchi branch into two tubes called the

Bronchioles

21

The bronchioles branch into grape like structures called the...

alveoli

22

What happens in the alveoli?

Gas exchange happens in the alveoli

23

What is gas exchange?

Gas exchange is the exchange of oxygen and carbon dioxide

24

How does waste carbon dioxide leave the body?

Via the blood to the lungs and out the mouth when you exhale. This is how carbon dioxide leaves the body

25

What is inhale?

inhale is to breath in

26

What is exhale?

Exhale is to breath out
