Respiratory System Flashcards
Is a form of respiration in which gas exchange occurs across the skin or outer integument of an organism rather than gills or lungs
Skin System
Aquatic animals uses gills to gets oxygen from the water.
Gills System
A respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide.
Gills
Gas exchange in some animals like insect takes place in their trachea, which are several air tubes that form a network in their bodies.
Tracheal System
Are respiratory openings found on the thorax and abdomen of insects.
Spiracles
Is the network of organs and tissues that allow you to breathe.
Lung System
Function of Respiratory System
Supplies the body with oxygen and disposes of carbon dioxide
Filters inspired air
Produces sound
Contains receptors for smell
Rids the body of some excess water and heat
Helps regulate blood pH
Types of Respiration
External Respiration
Internal Respiration
Cellular Respiration
An exchange of gases between the lungs and the blood.
External Respiration
An exchange of gases between the blood and tissue cells
Internal Respiration
The cells utilize the oxygen for their specific activities.
Cellular Respiration
Mechanics of Ventilation
Ventilation or Breathing
Pulmonary Ventilation
Is the movement of air through the conducting passages between the atmosphere and the lungs.
Ventilation or Breathing
Is the process of air flowing into the lungs and out of the lungs. Air flows because of pressure differences between the atmosphere and the gases inside the lungs.
Pulmonary Ventilation
Pulmonary Ventilation 3 different pressures
Atmospheric pressure
Interalveolar (intrapulmonary) pressure
Intrapleural pressure
The pressure of the air outside the body.
Atmospheric pressure
The pressure inside the alveoli of the lungs
Interalveolar pressure
