Answer 7

Lobes. The right has 3 and the left has 2

Question 8

Name some functions of the respiratory system?

Answer 8

1) filter, warm and humidity air
2) transport air from outside the body to the lungs
3) gas exchange between lungs and blood to enable oxygenation of body tissues
4) to expel waste products of cell metabolism such as C02

Question 9

What is the function of the nose and nasal cavity?

Answer 9

1) Warms, cleanses and humidifies
2) detects smell
3) amplifies voice

Question 10

What is the function of the pharynx?

Answer 10

Passageway for air, fluids and food

Question 11

What if the function of the larynx (voice box)?

Answer 11

1) sound production

2) keeps food and drink out of trachea

Question 12

What is the function of the bronchi?

Answer 12

Conducts air

Question 13

What is the function of the alveoli?

Answer 13

gas exchange occur

Question 14

Gas exchange occurs across the respiratory membrane, which is made up of what alveolar cells?

Answer 14

Squamous

Question 15

There are 2 types of alveoli, what type of cells are they made up of?

Answer 15

Type 1- squamous Epithelial cells

Type 2- round cuboidal Epithelial cells

Question 16

Oxygen diffuses from the alveoli to the pulmonary Venule. Co2 diffuses from the pulmonary arteriole to the ?

Answer 16

Alveoli

Question 17

What is internal respiration?

Answer 17

Oxygen is unloaded by the tissue capillaries and taken up by the tissue cells

Question 18

What is cell respiration?

Answer 18

The use of O2 and Co2 to produce energy in a process called aerobic respiration.

Glucose + O2 > Co2 + water + ATP

Question 19

Cilia and mucus are found in?

Answer 19

Trachea

Question 20

What 2 key processes are involved in the mechanism of breathing?

Answer 20

1) external respiration

2) internal respiration

Question 21

What is inspiration?

Answer 21

A process during normal, quiet breathing

Question 22

What are the main muscles involved in normal, quiet breathing in an adult?

Answer 22

Intercostal muscles and diaphragm

Question 23

Describe what occurs in enable inspiration?

Answer 23

The lung pressure is reduced when the diaphragm moves downwards and the thoracic cage moves upwards and outwards which increases the capacity of the lungs

Question 24

Where is the respiratory centre located?

Answer 24

In the brain stem

Question 25

The main stimulus of breathing is the increase in levels of Co2 in the blood. When level of Co2 in the bloody increases which is detected by?

Answer 25

The chemoreceptors
