Anatomy & Physiology

Front 1

The exchange of oxygen and carbon dioxide between the lungs and the blood is termed:

Back 1

External Respiration

Front 2

The epithelium lining the upper respiratory tract is:

Back 2

Pseudostratified ciliated columnar

Front 3

The common passageway for food and air:

Back 3

Pharynx

Front 4

The laryngeal cartilage which must be depressed to view the glottis when passing an endotracheal tube is the:

Back 4

Epiglottis

Front 5

Damage to these paired cartilages may result in a condition called "Roaring" in horses:

Back 5

Arytenoid

Front 6

Which of the following is included as part of the lower respiratory system:

Back 6

Alveoli

Front 7

Where the exchange of oxygen and carbon dioxide takes place, (between the blood and the air):

Back 7

Alveoli

Front 8

The serous membrane that lines the thoracic cavity is called:

Back 8

Parietal pleura

Front 9

Where the base of the lungs lie in the thoracic cavity:

Back 9

Cranial to the diaphragm

Front 10

The amount of air inspired and expired in one normal, relaxed breath is called:

Back 10

Tidal volume

Front 11

The respiratory center is located in what part of the brain:

Back 11

Medulla oblongata

Front 12

Cats have a very sensitive larynx which typically slams shut when trying to pass an endotracheal tube. This condition is called:

Back 12

Laryngeal spasm

Front 13

The common name for the nares is:

Back 13

Nostrils

Front 14

With respect to atmospheric pressure, the pressure in the lungs is:

Back 14

Negative

Front 15

Proceeding caudally, the trachea immediately divides into the:

Back 15

Bronchi

Front 16

Air in the thoracic cavity is referred to as:

Back 16

Pneumothorax

Front 17

This part of the respiratory tract is surrounded by smooth muscle, but no cartilage:

Back 17

Bronchioles

Front 18

Labored breathing:

Back 18

Dyspnea

Front 19

An abnormal buildup of carbon dioxide in the blood stream causes the:

Back 19

Blood pH to go lower and the blood to become more acid

Front 20

Progressing caudally, what part of the respiratory tract follows the pharynx:

Back 20

Larynx

Front 21

If the tidal volume of a dog is considered to be 5 cc's per lb. of body weight. What is the total tidal volume for a 36 lb dog?

Back 21

180 cc's

Front 22
