Anatomy Respiratory system

Question 1

Conductive zone

Answer 1

Brings inhaled air to the respiratory zone where gas exchange occurs

Question 2

External respiration

Answer 2

Exchange of gas between the lungs and blood

Question 3

Internal respiration

Answer 3

Exchange of gas between the blood tissues

Question 4

Gas exchange

Answer 4

The loading of oxygen into pulmonary blood and the removal of carbon dioxide

Question 5

Thermoregulation

Answer 5

A job of the respiratory system, is the regulation of body temperature

Question 6

Parietal pleura

Answer 6

Lines the chest cavity

Question 7

Visceral pleura

Answer 7

Covers the surface of the lungs

Question 8

Mediastinum

Answer 8

Central space in the thoracic (chest) cavity that lies between the two lungs

Question 9

Hilum

Answer 9

Central area on the medial side of each lung where important structures enter and exit the lung — kind of like the lung’s “gateway”

Question 10

Alveoli

Answer 10

Tiny air sacs where oxygen goes in and carbon dioxide comes out

Question 11

Respiratory membrane

Answer 11

Thin wall where oxygen enters the blood and carbon dioxide leaves — it’s where breathing becomes life

Question 12

Boyles law

Answer 12

When temperature is constant, the pressure of a gas increases as its volume decreases, and vice versa

Question 13

Inspiration

Answer 13

Inspiration = breathing in — lungs expand, air rushes in

Question 14

Negative-pressure breathing

Answer 14

Pulling air into the lungs by lowering lung pressure — like creating a vacuum

Question 15

Expiration

Answer 15

Expiration = breathing out — lungs shrink, pressure rises, and air is pushed out
