Respiration And Breathing

Question 1

Respiration

Answer 1

~ The process that releases energy from food is respiration

Question 2

Equation For Respiration

Answer 2

~ Glucose+Oxygen ➡️ Carbon dioxide+Water+Energy

Question 3

Aerobic Respiration

Answer 3

~ Aerobic respiration needs oxygen to release energy from food

Question 4

Anaerobic Respiration

Answer 4

~ Anaerobic respiration does not use oxygen to release energy from food.

Question 5

How Does Oxygen Get To Our Cells?

Answer 5

~ Oxygen is carried by the haemoglobin in red blood cells to all other cells of the body.

Question 6

Examples Of Anaerobic Respiration

Answer 6

~ Yeast converts sugar to alcohol in “Fermentation” - this produces alcohol for drinks such as beers and wine!

Question 7

Nose

Answer 7

~ We are supposed to inhale through our nose because the hairs and mucus trap dirt particles and bacteria in the nose.
~ Air is warmed and moistened by the blood vessels. Warm, moist air helps oxygen to pass from the lungs into the bloodstream more easily.

Question 8

Trachea

Answer 8

~ The trachea, or windpipe, carries air to and from the lungs. It is made of C-shaped rings of rigid cartilage to prevent it from collapsing.

Question 9

Bronchus and Bronchioles

Answer 9

~We have two bronchi. Each bronchus carries air between the trachea and a lung. The two bronchi subdivide many times to form tiny tubes called bronchioles. Bronchioles carry air to and from the alveoli.

Question 10

Alveolus

Answer 10

~ Each lung contains millions of tiny air sacs called alveoli. The function of each alveolus is gas exchange.

Question 11

Diaphragm

Answer 11

~The diaphragm is a sheet of muscle that forms the base of the chest. Along with ribs and intercostal muscles the diaphragm causes air to move into or out of the lungs.
