Questions Related to respiratory system

The trachea is prevented from collapsing by

  1. Complete cartilaginous rings

  2. Incomplete cartilaginous rings

  3. Bony rings

  4. Chitinous rings

Correct Option: B
  • The trachea is a rigid tube that conducts air from your larynx to your bronchi.
  • The trachea's rigidity is maintained by a series of incomplete cartilaginous rings arranged along its length called C-shaped cartilage rings. Hence, The trachea is prevented from collapsing by Incomplete cartilaginous rings.
So, the correct answer is 'Incomplete cartilaginous rings'.

The short tube leading from the nose is

  1. Pharynx

  2. Bronchi

  3. Trachea

  4. Alveoli

Correct Option: A

  • The pharynx, or throat, is the passageway leading from the mouth and nose to the oesophagus and larynx. 
  • The pharynx permits the passage of swallowed solids and liquids into the oesophagus, and conducts air to and from the trachea, or windpipe, during respiration. 
  • The pharynx also connects on either side with the cavity of the middle ear by way of the Eustachian tube and provides for equalization of air pressure on the eardrum membrane, which separates the cavity of the middle ear from the external ear canal. Hence, The short tube leading from the nose is pharynx.
So, the correct answer is 'pharynx'

Air goes from pharynx to.

  1. Trachea

  2. Bronchus

  3. Bronchi

  4. Bronchiole

Correct Option: A

  • The nasal cavity and the mouth meet at the pharynx, or throat, at the back of the nose and mouth. 
  • From there, air quickly enters the second part of your respiratory system, the trachea or windpipe. 
  • The trachea is a tube that delivers air to the lungs, the third and most important part of your respiratory system. Hence, Air goes from the pharynx to. trachea.
So, the correct answer is 'trachea'.

Which of the following can be considered as odd one?

  1. Larynx

  2. Glucagon

  3. Testosterone 

  4. Prolactin

Correct Option: A
Larynx is the sound box while the rest three glucagon, testosterone and prolactin are hormones.
So, the correct answer is 'Larynx'.

Which of the following two diseases together are referred to as chronic obstructive lung disease (COLD) or chronic obstructive airways disease?

  1. Acute bronchitis and chronic bronchitis

  2. Chronic bronchitis and emphysema

  3. Tuberculosis and emphysema

  4. Tuberculosis and chronic bronchitis

Correct Option: B

  1. Chronic bronchitis is a disease caused by the inflammation of bronchitis which secretes mucous leads to coughing and breathing difficulty and commonly observed in smokers.
  2. Emphysema is a disease in which alveolar sacs get damage which results in the deficiency in the amount of oxygen required by the body and its common cause is also smoking.
When these two diseases found together in a patient it is referred to as chronic obstructive lung disease (COLD) or chronic obstructive airways disease.
So the correct option is 'Chronic bronchitis and emphysema'.

Which of the following disease affects alveoli of lungs?

  1. Pneumonia

  2. Emphysema

  3. Asthma

  4. $(1)$ and $(2)$

Correct Option: A

Inflammation of the lung covering causing severe chest pain is

  1. Emphysema

  2. Pleurisy

  3. Asphyxia

  4. Hypoxia

Correct Option: B

Pleurisy involves inflammation of the tissue layers (pleura) lining the lungs and inner chest wall. Pleurisy is often associated with the accumulation of fluid between the two layers of pleura, known as pleural effusion. Symptoms of pleurisy include pain in the chest, which is aggravated by breathing in, shortness of breath, and local tenderness. The diagnosis of pleurisy is made by the characteristic chest pain and physical findings on examination of the chest. The pleural accumulation of fluid (pleural effusion) can be seen by imaging studies.

Match the columns and find out the correct combination.

Column I Column II
(a) Asthma (i) Inflammation of nasal tract
(b) Bronchitis (ii) Spasm of tracheal muscle
(c) Rhimitis (iii) Fully blown out alveoli
(d) Emphysema (iv) Inflammation of bronchi
(v) Cough with blood stained sputum
  1. a-iv, b-ii, c-v, d-i

  2. a-v, b-iii, c-ii, d-i

  3. a-iii, b-i, c-v, d-iv

  4. a-ii, b-iv, c-i, d-iii

  5. a-iii, b-i, c-iv, d-ii

Correct Option: D

Inflammatory condition of lungs is called

  1. coryza

  2. pneumonia

  3. laryngitis

  4. nasopharymgits

Correct Option: B

Coryza is an inflammatory condition of the mucous membrane of the nose. Inflammatory condition of lungs is called pneumonia. Laryngitis is an inflammatory condition of larynx. Nasopharyngitis is the inflammatory condition of nose and pharynx.

Thus, the correct answer is option B.

Chemicals in cigarette smoke lead to the breakdown of the walls of the alveoli. What is the name given to this disease ?

  1. Bronchitis

  2. emphysema

  3. coronary heart disease

  4. lung cancer

Correct Option: A

Bronchitis is inflammation of the bronchi (large and medium-sized airways) in the lungs. Symptoms include coughing up mucus, wheezing, shortness of breath, and chest discomfort, such mainly occurs due to large consumption of smoke which leads to the breakdown of the walls of alveoli. 

So, 'the correct option is Bronchitis'.
