Mouth

Alveoli

Bronchioles

Epiglottis

Bronchi

Nasal cavity

Trachea

Which is NOT a process of respiration?

• external respiration

• transport of O2 and CO2

• internal respiration

• filtration and secretion

• pulmonary ventilation

Pulmonary ventilation is also known as

• external respiration

• internal respiration

• breathing

• diffusion

Where does external respiration occur?

• tissue cells

• mouth & nose

• lungs

• heart

What happens during external respiration?

• O2 diffuses out from the lungs into the blood; CO2 diffuses into the lungs from the blood

• O2 diffuses into the lungs from the blood; CO2 diffuses out of the lungs into the blood

• O2 diffuses out from the tissues into the blood; CO2 diffuses into the tissues from the blood

• O2 diffuses into the tissues from the blood; CO2 diffuses into the tissues from the blood

What happens during internal respiration?

• O2 diffuses out from the lungs into the blood; CO2 diffuses into the lungs from the blood

• O2 diffuses into the lungs from the blood; CO2 diffuses out of the lungs into the blood

• O2 diffuses out from the tissues into the blood; CO2 diffuses into the tissues from the blood

• O2 diffuses into the tissues from the blood; CO2 diffuses into the blood from the tissues

Categorize the following parts of the respiratory system correctly

Groups:

(a) Pharynx

,

(b) Larynx

,

(c) Trachea

• the throat

• the voice box

• passes air to the trachea

• supported by rings of cartilage

• the windpipe

• splits into the esophags and larynx

Organize these options into the right categories

Groups:

(a) Alveoli

,

(b) Bronchi

,

(c) Bronchioles

• each lead to a lung

• covered in capillaries

• thin-walled air sacs

• two branches at the bottom of the trachea

• Small branches within the lungs

Organize these options into the right categories

Groups:

(a) Nasal cavity

,

(b) Nose

,

(c) Epiglottis

,

(d) Diaphragm

• relaxes to cause expiration

• dome-shaped muscle wall beneath the lungs

• hollow area behind the nose

• opens during breathing

• full of hair and mucus to trap microbes and dust

• closes during eating

• contracts to cause inspiration

• door at the top of the larynx

Alveoli have enormous __ to increase the rate of diffusion of CO2 and oxygen.
