Respiratory System Activity 2

Question 1

This is the rebound of the lung tissues after having been stretched by inspiration

Answer 1

Elastic recoil

Question 2

This is the gaseous product that is normally expelled through the lungs

Answer 2

Carbon dioxide

Question 3

What are the folds of tissue located in the larynx that vibrate when air passes over them producing the sound waves associated with talking

Answer 3

Vocal cords

Question 4

The force around us which provides the force that moves air into lungs

Answer 4

Atmospheric pressure

Question 5

What is the dome shaped sheet of internal skeletal muscle that extends across the bottom of the thoracic cavity

Answer 5

Diaphragm

Question 6

The serous membrane that firmly covers the surface of each lung into the fissures between the lungs

Answer 6

Visceral pleura

Question 7

These projection line the trachea and help filter incoming air and entrap inhaled unwanted particles

Answer 7

Cilia

Question 8

This response in the lungs is part of the fight or flight response triggered by the sympathetic nervous system

Answer 8

Bronchodilation

Question 9

The passageway for food moving from the oral cavity to the oesophagus and for air passing between the nasal cavity and the larynx

Answer 9

Pharynx

Question 10

This is a tube like portion of the respiratory tract that connects the larynx with the bronchial parts of the lungs

Answer 10

Trachea

Question 11

This consists of branched airways leading from the trachea to the microscopic air sacs in the lungs

Answer 11

Bronchial tree

Question 12

This colourless gas is essential for respiration which binds with haemoglobin

Answer 12

Oxygen

Question 13

This is the movement of air into and out of the lungs via inhalation and exhalation

Answer 13

Pulmonary ventilation

Question 14

This is the volume of air that is inspired and then expired in a single breath or respiratory cycle and measures approximately 500ml

Answer 14

Tidal volume

Question 15

This is a double layered serous membrane found in the thoracic activity. The outer layer is called the parietal pleura and the inner layer is the visceral pleura. What do these both make up

Answer 15

Pleural membrane

Question 16

The potential space between the visceral and parietal pleurae

Answer 16

Pleural cavity

Question 17

The substance made from the combination of oxygen and haemoglobin

Answer 17

Oxyhaemoglobin

Question 18

This helps regulate the depth of breathing using stretch receptors and prevents over inflation of the lungs during the forceful breathing

Answer 18

Inflation reflex

Question 19

This is part of the respiratory tract between the pharynx and the trachea; it also contains the vocal chords

Answer 19

Larynx
