Answer 0

Covers the internal surfaces of the thoracic wall and is separated by the endothoracic fascia

Question 1

What are the four parts of the parietal pleura?

Answer 1

Costal part, mediastinal part, diaphargmatic part, cervical pleura

Question 2

What is the mediastinal part of the parietal pleura?

Answer 2

Covers the lateral aspects of the mediastinum

Question 3

What is the diaphragmatic part of the parietal pleura?

Answer 3

Covers the superior surface of the diaphragm on each side of the mediastinum

Question 4

What is the cervical pleura of the parietal pleura?

Answer 4

Forms a cup shaped dome over the apex of the lung

Question 5

What is the potential space between the parietal and visceral pleura?

Answer 5

Pleural cavity

Question 6

What can be found in the pleural cavity?

Answer 6

Parietal fluid which lubricates the pleural surface and allows the layers to slide over one another during respiration

Question 7

What innervates the lungs and visceral pleura?

Answer 7

Parasympathetic fibers from the vagus nerve (CN X) and sympathetic fibers from the sympathetic trunks

Question 8

What innervates the costal and peripheral parietal pleura?

Answer 8

Intercostal nerves

Question 9

What innervates the central and diaphragmatic parietal pleura?

Answer 9

Phrenic nerve

Question 10

What are the three surfaces of the lungs?

Answer 10

Costal, mediastinal, and diaphragmatic

Question 11

What are the three borders of the lungs?

Answer 11

Anterior, inferior, and posterior borders

Question 12

What encloses the root of the lungs?

Answer 12

Parietal sleeve

Question 13

What structures form the root of the lung?

Answer 13

Main bronchus, pulmonary vessels, bronchial vessels, lymphatic vessels, and nerves

Question 14

What supports the walls of the trachea and bronchi?

Answer 14

C shaped hyaline cartilages

Question 15

What does the respiratory bronchiole give rise to?

Answer 15

2 to 11 alveolar ducts

Question 16

What does each alveolar duct give rise to?

Answer 16

5 to 6 alveolar sacs

Question 17

What is the basic structural unit of gas exchange of lung?

Answer 17

Pulmonary alveolus

Question 18

Where do the right and left pulmonary arteries arise from?

Answer 18

The pulmonary trunk at the level of the sternal angle

Question 19

What type of blood do the pulmonary arteries carry?

Answer 19

Poorly oxygenated (venous) blood

Question 20

Where do pulmonary arteries carry blood?

Answer 20

Away to the lungs for oxygenation

Question 21

What type of blood do pulmonary veins carry?

Answer 21

Well oxygenated (arterial) blood

Question 22

Where do pulmonary veins carry blood?

Answer 22

From the lungs to the left atrium of the heart

Question 23

What do the bronchial arteries supply?

Answer 23

The root of the lungs, supporting tissues of lung, and visceral pleura

Question 24

Where do the left bronchial arteries arise from?

Answer 24

Thoracic aorta

Question 25

What is ventilation?

Answer 25

Movement of air into and out of the lungs (inhalation and exhalation)

Question 26

What is respiration?

Answer 26

The process of exchanging gases, mainly oxygen and carbon dioxide

Question 27

What is external respiration?

Answer 27

The exchange of oxygen and carbon dioxide between the blood and fresh air between alveoli of lungs and capillaries of the pulmonary circulatory system
