Respiratory System

Question 1

How does the RS contribute to homeostasis?

Answer 1

By exchanging gases, Carbon Dioxide and oxygen

Question 2

What ways does the RS gas exchange?

Answer 2

Through blood, atmospheric air, and tissue cells

Question 3

What systems supply oxygen and eliminate CO2?

Answer 3

The Cardiovascular system and Respiratory system

Question 4

What system regulates the body’s pH?

Answer 4

Cardiovascular system

Question 5

What are the steps of respiration

Answer 5

Pulmonary ventilation
External respiration
Internal respiration

Question 6

Pulmonary ventilation

Answer 6

The inflow and outflow of air (gas exchange)

Question 7

External respiration

Answer 7

The exchange of gases between the pulmonary alveoli and the blood in pulmonary capillaries

Question 8

Pulmonary capillary gas exchange looks like…
Hint chemicals

Answer 8

Gains oxygen and looses carbon dioxide

Question 9

Internal respiration

Answer 9

Exchange of gases between blood in systemic capillaries and tissue cells.

Question 10

Internal respiration gas’s exchanges look like…

Answer 10

Blood looses oxygen and gains carbon dioxide

Question 11

What influences rate of airflow

Answer 11

Alveolar surface tension, compliance, and airway resistance

Question 12

Boyle’s Law

Answer 12

The inverse relation of volume and pressure

Question 13

2 different types of inhalation pressures

Answer 13

Intrapleural pressure
Alveolar pressure

Question 14

Intrapleural pressure

Answer 14

Decreasing pressure between the parietal pleural membrane and the visceral pleural membrane

Question 15

Alveolar pressure

Answer 15

Intrapulmonic pressure inside the lungs caused by space growing for lungs to expand

Question 16

How do lungs heal?

Answer 16

Lungs are self-healing

Question 17

Where does gas exchange take place?

Answer 17

In the Alveolus, Alveolar sacs

Question 18

The lungs have 2 types of epithelial tissues. What are they?

Answer 18

Dust cells and Septal cells

Question 19

Dust cells

Answer 19

Macrophages responsible for cleaning out dust in the lungs.

Question 20

Dust cell make up cell type and how does this help gas exchange?

Answer 20

Simple squamous covered by basement membrane. Gas can travel easily across

Question 21

Septal cells

Answer 21

Secretes lubricant inside the lungs calls surfactant

Question 22

Pulmonary circulation

Answer 22

Is where blood enters and exists the lungs

Question 23

Ventilation-perfusion coupling

Answer 23

Blood flow to each area of the lungs matches extent of airflow to the alveoli in the lungs
