This set of Human Anatomy test focuses on “Splanchnology – Pleurae, Lungs, Trachea and Bronchi”.
1. Where does the arterial blood come from those supplies to visceral pleura?
a) Bronchial veins
b) Intercostal nerves
c) Bronchial arteries
d) The costodiaphragmatic recesses
View Answer
Explanation: Bronchial arteries supply lungs with nutrition and oxygenated blood. There are usually two bronchial arteries that run to the left lung and one to right lung.
2. What is the dry form of inflammation without a significant collection of fluid in the pleural cavity called?
a) Intercostal nerves
b) Pleura
c) Pleurisy
d) Pneumothorax
View Answer
Explanation: Pleurisy is also called as pleuritis. It is the inflammation of membranes that surround lungs and lines the chest cavity.
3. What are the innervations to the costal and peripheral parts of the diaphragmatic pleura?
a) Hydropneumothorax
b) Intercostal nerves
c) Bronchial arteries
d) Empyema thoracis
View Answer
Explanation: Intercostal nerves arise from somatic nervous system. This enables them to control the contraction of muscles as well as provide specific sensory information regarding the skin and parietal pleura.
4. What does the pulmonary ligament contain?
a) The inner surface of the thoracic wall
b) Interpleural space/ Pleural cavity
c) A thin layer of areolar tissue with a few lymphatics
d) The pulmonary veins to expand during the increased venous return, such as during exercise
View Answer
Explanation: Pulmonary ligament serves to hold the lower part of lungs in position. It contains a thin layer of areolar tissue with a few lymphatics.
5. What part of the parietal pleura covers the superior surface of the diaphragm?
a) Mediastinal pleura
b) Diaphragmatic pleura
c) Intercostal nerves
d) Pneumothorax
View Answer
Explanation: Diaphragmatic pleura is a layer of parietal peritoneum overlaying the thoracic surface of the diaphragm and the lung.
6. The respiratory system is made up of trachea, the lungs and the _________
a) Diaphragm
b) Pancreas
c) Esophagus
d) Liver
View Answer
Explanation: Diaphragm is a dome shaped sheet of muscles and tendon that serves as the main muscles of respiration and plays vital role in breathing process. It separates the thorax, or chest from the abdomen.
7. Two lungs are of the same size.
a) True
b) False
View Answer
Explanation: The two are not of the same size. The left lung is approximately 10%smaller than right one. This is due to the position of the heart.
8. ___________ delivers deoxygenated blood to the lungs.
a) Pulmonary vein
b) Aorta
c) Left ventricle
d) Pulmonary artery
View Answer
Explanation: Pulmonary artery carries deoxygenated blood from right ventricle to the lungs. The blood passes through capillaries adjacent to alveoli and becomes oxygenated as a part of respiration process.
9. The inner layer that surrounds the lung itself is called ________
a) Parietal Pleura
b) Lobar bronchi
c) Pleuracardium
d) Visceral Pleura
View Answer
Explanation: Visceral Pleura is a delicate membrane that covers the surface of each lung and dips into fissures between the lobes. It also separates the pleural cavity from the mediastinum.
10. Gas exchange in lungs occurs in __________
a) Alveolar sacs
b) Segmental Bronchi
c) Bronchioles
d) Alveolar sinus
View Answer
Explanation: Alveoli are tiny sacs in our lungs. It allows oxygen and carbon dioxide to move between the lungs and bloodstream.
11. How many secondary bronchi are there in the right lung?
a) 2
b) 3
c) 4
d) 1
View Answer
Explanation: There are 3 secondary bronchi in right lung. It delivers oxygen to three lobes of the right lung. The lobes are superior middle and inferior lobe.
12. Which of the following supports epiglottis?
a) Cricoid cartilage
b) Thyroid
c) Ribs
d) Lungs
View Answer
Explanation: Cricoid cartilage is located slightly below the thyroid cartilage. This cartilage consists of strong connective tissue consisting the dorsal part of larynx.
13. Point where bronchial enters lung is ___________
a) Manus briosternal
b) Hilus
c) Bronchi
d) Carina
View Answer
Explanation: It is also known as hilum. They consist of major bronchi and pulmonary arteries and veins. It is found in medial aspect of each lung.
14. Place where trachea bifurcates into right and left bronchus is ____________
a) Trachea
b) Bronchi
c) Hilus
d) Carina
View Answer
Explanation: Carina is a ridge of cartilage in the trachea that occurs between the divisions of the two main bronchi. It occurs at the lower end of the trachea.
