-Also functions in digestive system
-Divided into three portions

Answer 12

Pharynx

Question 13

Superior portion of the pharynx located behind the nasal cavity

Answer 13

Nasopharynx

Question 14

Middle portion of the pharynx located behind the mouth

Answer 14

Oropharynx

Question 15

Answer 15

Laryngopharynx

Question 16

A hollow, fibro-muscular and cartilaginous structure connecting to the pharynx to the trachea.
-Anterior to the esophagus
-Lined with epithelial tissue that is slightly different above and below the vocal cords
-Thyroid cartilage is the largest cartilage of the ___ and sits below the hyoid bone

Answer 16

Larynx

Question 17

The Larynx contains the ___ ___, which are fibrous bands that function in voice and sound production.
-Epiglottis and Glottis

Answer 17

Vocal cords

Question 18

The structure that closes during swallowing to prevent food from entering the respiratory tract

Answer 18

Epiglottis

Question 19

The space between the vocal cords

Answer 19

Glottis

Question 20

Fibrocartilaginous, muscular tube that functions in transporting O2 into and out of the lungs.
-Posterior section is made of muscle tissue
-Anterior portion is C-shaped rings of cartilage
-Lined with epithelial tissue

Answer 20

Trachea

Question 21

Fibromuscular, cartilaginous tubes leading from the trachea into the lungs.
-Lined with epithelial tissue
-Primary lead into smaller secondary ___
-Secondary branch into bronchioles
-Bronchioles eventually lead to alveoli within the lungs

Answer 21

Bronchi

Question 22

Small air sacs at the end of the bronchial tree that function in gas exchange between O2 and CO2
-Surrounded by a network of blood capillaries that lead back to the pulmonary artery
-Respiratory membrane on the ___ is very thin so that blood cells can pass through the capillaries

Answer 22

Alveoli

Question 23

What is the Alveolar process?

Answer 23

1. Inhalation occurs
2. O2 makes it’s way to the alveoli
3. O2 enters the blood stream
4. Exhalation occurs
5. CO2 leaves the red blood cells and enter the alveoli
   6.CO2 is exhaled

Question 24

Spongy organs in the thoracic cavity that function in inhalation and exhalation on a gross scale and gas exchange between CO2 and O2 on a microscopic scale
-Right is larger than left and has three lobes
-Left is samller and has two lobes (to account for the heart)
-Lobes are divided by grooves called fissures
-Sections may be referred to as bronchopulmonary segments

Answer 24

Lungs

Question 25

1.Superior, narrow portion
2.Broad, inferior portion
3. Where the pulmonary artery, pulmonary veins, and bronchi enter the lungs
4. The membrane surrounding each lung
5. Adheres directly to the lung
6. Adheres to the thoracic wall. diaphragm, ect

Answer 25

1. Apex
2. Base
3. Hilum
4. Pleura
5. Visceral pleura
6. Parietal pleura
