Pulmonary System Pathology Trivia Quiz

2.

Which of these is not part of the pulmonary system?

Lungs
Liver
Diaphragm
Pharynx

Correct Answer

A. Liver

Explanation

The pulmonary system is responsible for the exchange of gases in the body, particularly oxygen and carbon dioxide. The lungs are the main organ involved in this process, as they facilitate the intake of oxygen and release of carbon dioxide. The diaphragm is a muscle located below the lungs that aids in the process of breathing by contracting and relaxing. The pharynx is a part of the respiratory system that connects the nose and mouth to the larynx and esophagus. However, the liver is not part of the pulmonary system. It is primarily involved in detoxification, metabolism, and synthesis of various substances in the body.

Which of these lacks cartilaginous support?

Trachea
Bronchioles
Larynx
Nose

Correct Answer

A. Bronchioles

Explanation

The bronchioles lack cartilaginous support. Unlike the trachea and larynx, which have rings of cartilage to maintain their shape and prevent collapse, the bronchioles are small airways in the lungs that do not have cartilage. Instead, they are surrounded by smooth muscle, allowing them to constrict and dilate to regulate airflow. The nose also contains cartilage, particularly in the nasal septum, which helps maintain its structure. Therefore, the correct answer is bronchioles.

Which of these is not a symptom of asthma?

Shortness of breath
Coughing
Sneezing
Tightness of breath

Correct Answer

A. Sneezing

Explanation

Sneezing is not a symptom of asthma. Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to symptoms such as shortness of breath, coughing, and tightness of breath. However, sneezing is not typically associated with asthma. Sneezing is more commonly linked to allergies or colds, which can sometimes trigger asthma symptoms in individuals with the condition.

What is the total residual which can not be measured by spirometry?

2.5 liters
1.5 liters
3 liters
4.5 liters

Correct Answer

A. 1.5 liters

Explanation

Spirometry is a pulmonary function test that measures the volume of air a person can inhale and exhale. However, spirometry cannot measure the residual volume, which is the amount of air remaining in the lungs after a maximal exhale. The correct answer, 1.5 liters, represents the total residual volume that cannot be measured by spirometry.

Which of these does not trigger asthmatic attacks?

Cold air
Physical activity
Optimum exercise
Air borne substances

Correct Answer

A. Optimum exercise

Explanation

Optimum exercise does not trigger asthmatic attacks because it refers to a level of physical activity that is well-suited to an individual's fitness level and does not exceed their capacity. In contrast, cold air, physical activity, and airborne substances can all be triggers for asthmatic attacks. Cold air can cause airway constriction, physical activity can lead to increased breathing and potential exposure to allergens, and airborne substances such as pollen or dust can irritate the airways and trigger an asthma attack.

What physical law is obeyed by the pulmonary system?

Charles' law
Boyle's law
Achimedes law
Law of floatation

Correct Answer

A. Boyle's law

Explanation

Boyle's law states that the pressure and volume of a gas are inversely proportional at a constant temperature. In the pulmonary system, the lungs expand and contract to regulate the pressure and volume of air. When the volume of the lungs increases, the pressure decreases, allowing air to be drawn into the lungs. When the volume decreases, the pressure increases, allowing air to be expelled from the lungs. Therefore, the pulmonary system obeys Boyle's law to regulate the exchange of air in the lungs.

What is the total lung capacity in humans?

35 liters
6 liters
10 liters
15 liters

Correct Answer

A. 6 liters

Explanation

The correct answer is 6 liters. The total lung capacity in humans refers to the maximum amount of air that the lungs can hold. It is the sum of the vital capacity and the residual volume. The vital capacity is the maximum amount of air that can be exhaled after a maximum inhalation, which is typically around 4-5 liters. The residual volume is the amount of air that remains in the lungs after a maximum exhalation, which is around 1-2 liters. Therefore, the total lung capacity is approximately 6 liters.

9.

Which of these acts as an air conduit?

Bronchi
Trachea
Lungs
Diaphragm

Correct Answer

A. Trachea

Explanation

The trachea acts as an air conduit. It is a tube-like structure that connects the larynx to the bronchi in the lungs. It allows air to pass in and out of the lungs, facilitating respiration. The trachea is lined with ciliated epithelial cells and is supported by C-shaped cartilage rings, which help keep it open and prevent collapse.

10.

Which of these is not a type of asthma?

Occupational asthma
Allergy-induced asthma
Hereditary asthma
Exercise-induced asthma

Correct Answer

A. Hereditary asthma

Explanation

Hereditary asthma is not a type of asthma. Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, resulting in symptoms such as wheezing, coughing, and shortness of breath. Occupational asthma is triggered by exposure to certain substances in the workplace, allergy-induced asthma is caused by allergens such as pollen or pet dander, and exercise-induced asthma is brought on by physical exertion. However, hereditary asthma refers to a genetic predisposition to developing asthma, rather than a distinct type of asthma itself.
