Resporation And Breathing

Question 1

Ingredients for energy

Answer 1

We've learned in digestion that food is absorbed into our bloodstream and carried around to all the cells in our body!
• The process that releases energy from this food is
RESPIRATION

Question 2

Respiration is the release of energy from food.

Answer 2

The equation for respiration in words is:
• Glucose * Oxygen - * Carbon dioxide + Water + energy

Question 3

Airobic respiration

Answer 3

Airobic 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 haemogloblin in red cells to all other cells of the body

Question 6

Examples of anaerobic respiration

Answer 6

Yeast converts sugars to alcohol in fermentation this produces alcohol for drinks such as beers and wine

Question 7

Nose

Answer 7

We inhale through our nose because hairs and mucus trap dirt particles and bacteria in the nose air is warmed and moistened as it passes through the nose warm and 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 air-sacs or alveoli

Question 10

Alveolus

Answer 10

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