Anatomy Unit 9 Mid Flashcard Questions

Front

The process of continuously moving air in and out of the lungs.

Back

pulmonary ventilation

Front

The process by which gas exchange occurs between the alveoli in the lungs and the pulmonary blood.

Back

external respiration

Front

The process by which air flows INTO the lungs. It is also called inhalation.

Back

inspiration

Front

The process by which air is expelled from the lungs. It is also called exhalation.

Back

expiration

Front

Stretch receptors in the bronchioles and alveoli which trigger a reflex to prevent over-inflation of the alveoli is called the

Back

Hering-Breuer reflex

Front

Sensory cells in the brain that monitor the changes in pH of the cerebrospinal fluid (acid or base). A decrease in pH (more acidic) indicated high levels of CO2 in the body. It then send impulses through cranial nerves telling the body to inhale.

Back

central chemoreceptors

Front

A receptor located in the aortic artery (aorta) is sensitive to changes in blood "oxygen" levels. It uses cranial nerves to regulate breathing.

Back

peripheral chemoreceptors

Front

A receptor located in muscles and joints. As muscles are used, they send a message to the brain to increase respiration like when you work out.

Back

mechanoreceptor

Front

This measures the amount of air inhaled in a normal breath. (for 6 breaths)

Back

Tidal Volume (TV)

Front

You inhale as much as possible (maximum), and then exhale as much as possible. The total amount of air you took in and exhaled is called the:

Back

Vital Capacity (VC)
