Question 2

What does the circulatory system include.

Answer 2

The circulatory system includes the heart, blood and blood vessels

Question 3

Answer 3

Red blood cells in blood carry oxygen to the cells.

Question 4

What happens when the body uses oxygen?

Answer 4

When oxygen is used by cells carbon dioxide is waste

Question 5

What happens to the waste carbon dioxide?

Answer 5

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

Question 6

Question 9

What are the three types of blood vessels?

Answer 9

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

Question 10

What are arteries?

Answer 10

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

Question 11

What are veins?

Answer 11

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

Question 12

What are capillaries?

Answer 12

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

Question 13

What is the role of the heart?

Answer 13

The role of the heart is to pump blood

Question 14

How many chambers does the heart have?

Answer 14

The heart has four chambers

Question 15

Answer 15

The upper chambers are the right and left atrium

Question 16

What are the lower chambers?

Answer 16

The lower chambers are called the right and left ventricles

Question 17

What is the order of blood flow through the heart?

Answer 17

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

Question 18

What makes up the respiratory system?

Answer 18

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

alveoli

Question 22

What happens in the alveoli?

Answer 22

Gas exchange happens in the alveoli

Question 23

What is gas exchange?

Answer 23

Gas exchange is the exchange of oxygen and carbon dioxide

Question 24

How does waste carbon dioxide leave the body?

Answer 24

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

Question 25

What is inhale?
