Breathing and Respiration Y8

Question 1

Plasma

Answer 1

Liquid part of the blood

Question 2

Haemoglobin

Answer 2

Substance found in red blood cells that carries oxygen

Question 3

Platelets

Answer 3

Tiny fragments of cells in the blood which help the blood to clot

Question 4

Respiration

Answer 4

A process in a cell in which energy is released from glucose so it can be used by the cell

Question 5

Aerobic Respiration

Answer 5

A type of respiration which needs oxygen

Question 6

Anaerobic Respiration

Answer 6

A type of respiration that does not need oxygen

Question 7

Mitochondria

Answer 7

Part of the cell in which respiration occurs

Question 8

Gas exchange

Answer 8

Exchange of oxygen and carbon dioxide, e.g. in the lungs

Question 9

Breathing

Answer 9

The movement of muscles that make the lungs expand and contract

Question 10

Ventilation

Answer 10

Movement of air in and out of the lungs

Question 11

Inhalation

Answer 11

Breathing In

Question 12

Exhalation

Answer 12

Breathing Out

Question 13

Cilia

Answer 13

Small hair-like structures found on cells lining the air passages

Question 14

Alveoli

Answer 14

Tiny pockets in the lung where gases are exchanged

Question 15

Capillary

Answer 15

A tiny thin-walled blood vessel that e.g. delivers oxygen and nutrients to cell

Question 16

Diffusion

Answer 16

When particles move from a high to low concentration e.g. oxygen diffuses from the alveoli into the blood in the lungs

Question 17

Tissue Fluid

Answer 17

Liquid that surrounds cells. Forms when plasma leaks out of the capillaries, carrying oxygen and glucose to cells

Question 18

Vein

Answer 18

Blood vessel that carries blood from the capillaries to the heart

Question 19

Carbon Monoxide

Answer 19

Poisonous gas found in cigarette smoke that prevents blood from carrying oxygen

Question 20

Emphysema

Answer 20

Disease of the lungs where alveoli are damaged

Question 21

Nicotine

Answer 21

Addictive drug found in cigarette smoke

Question 22

Tar

Answer 22

Substance found in cigarette smoke that can cause cancer

Question 23

Correlation

Answer 23

A relationship between 2 variables

Question 24

Stomata

Answer 24

Tiny holes in a leaf through which gases enter and leave by diffusion

Question 25

Lactic Acid

Answer 25

Substance produced by muscle cells when they respire anaerobically
