A hormone produced by the adrenal glands in response to fear or stress. It increases the heart rate and boosts the delivery of blood to the brain and muscles as part of the ‘fight or flight’ response

Question 2

Aorta

Answer 2

The main artery that takes oxygenated blood away from the heart to the body

Answer 3

A type of blood vessel that carries blood at high pressure away from the heart to the tissues

Question 4

Atria

Answer 4

The two upper chambers of the heart that receive blood from the veins and pump blood into the ventricles

Question 5

Blood

Answer 5

A tissue containing red blood cells, white blood cells, platelets and plasma

Question 6

Haemoglobin

Answer 6

The red protein found in red blood cells transports oxygen in the blood

Question 7

Answer 7

An organ that pumps blood around the body in a double circulatory system

Question 8

Answer 8

The artery that supplies the liver with oxygenated blood

Question 9

Answer 9

The vein that carries blood away from the liver

Question 10

Cells in the blood that transport oxygen. They have a biconcave shape, no nucleus, and contain haemoglobin

Question 17

Root hair cells

Answer 17

Specialised cells responsible for the absorption of water and mineral ions from the soil in plants

Question 18

Translocation

Answer 18

The movement of sugars through the phloem tissue from sources to sinks

Question 19

Answer 19

Water loss from plant leaves and shoots via diffusion and evaporation

Question 20

Vena cava

Answer 20

The main vein that takes deoxygenated blood back to the heart from the body

Question 21

Ventricles

Answer 21

The two lower chambers of the heart that receive blood from the atria and expel blood into the arteries
