Respiratory Anatomy

Front 1

Respiratory system function

Back 1

1. Exchange of gases between the atmosphere and the blood
2. Homeostatic regulation of the body pH
3. Protection from in held pathogens and irritating substances
3. Vocalization what is the

Front 2

What is the ideal pH for blood

Back 2

7.4

Front 3

Acidosis

Back 3

Blood at or below a pH of 3.5

Front 4

Alkalosis

Back 4

Blood at or above a pH of 7.45

Front 5

How does the respiratory system control the blood pH?

Back 5

It controls the acidity of the blood by regulating the elimination of CO2 and H2O

Front 6

Hyperventilation

Back 6

Occurs when there is a significant increase in CO2 or a decrease be low pH 7.35

More CO2 is exhaled and eliminated, reduces H2CO3 and H+ concentrations

Increase pH back to normal

Front 7

Hypoventilation

Back 7

Occurs when there is a significant DECREASE in CO2 or a INCREASE in pH

Less CO2 is exhaled , increases CO2 increases H2CO3 and H+ concentrations

Decreases pH back to normal

Front 8

Pulmonary ventilation

Back 8

When the air must move in and out of the lungs so that gases and the air sacs of the lungs are continuously replaced

Front 9

Nasopharynx

Back 9

Prevents food from entering the nasal cavity

Front 10

Tonsils

Back 10

Destroy entering pathogens and protect against infection

Front 11

Nasal conchae

Back 11

Moistens and helps warm the air. While foreseeing and held air to flow in a steady regular pattern around the largest possible surface of the cilia and climate controlling tissue

Front 12

Conducting system

Back 12

Function is to filter warm and moisten the air and conduct it into the lungs

Front 13

Tubal Tonsil

Back 13

Provides the middle ear some protection against infection that may spread from the pharynx

Front 14

Vocal folds (true vocal cords)

Back 14

Act in sound production

Front 15

Vestibular folds (false vocal cords)

Back 15

Keep food and drink out of the airway breathing and speech
