Respiration

Question 1

The equation for respiration in words is

Answer 1

Glucose+oxygen-> Carbon dioxide+water+energy

Question 2

Respiration

Answer 2

Getting energy from food

Question 3

Aerobic respiration

Answer 3

Needs oxygen to release energy

Question 4

Anaerobic respiration

Answer 4

Does not need oxygen to release energy from food

Question 5

Nose

Answer 5

We are supposed to
inhale through our nose.
The reasons for doing
this are:
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 6

Trachea

Answer 6

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 7

Bronchus and bronchioles

Answer 7

We have two bronchi. Each bronchus carries air between the trachea and a lung. The two
bronchi form tiny cubed called bronchioles. Bronchioles carry air to and
from the air-sacs, or alveoli.

Question 8

Alvaeolus

Answer 8

Each lung contains millions of tiny air-sacs called alveoli.
The function of each alveolus is oxygen goes to the blood cells via the alvaeolus And carbon and water go to the alvaeoulus too
The gases pass in each direction by a process called diffusion.
As an adaptation for diffusion each alveolus has a very thin
lining, is moist and is surrounded by many tiny blood vessels
called capillaries.
