BIOXI17: BREATHING AND EXCHANGE OF GASES
338843
Assertion : Mammals can eat while breathing Reason : Mammals have negative pressure breathing
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
In mammals it is the secondary palate that permits breathing while eating. Clearly, breathing while eating is necessary to maintain the high rate of metabolism of mammals. Mammals possess negative pressure breathing (air is sucked into the lungs) Breathing in humans is dependent on regular contractions of the thoracic muscles and the diaphragm.

Assertion : Trachea and bronchioles are supported by elastic cartilage Reason : This support of incomplete cartilages prevents collapse of wind pipe during respiration.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Trachea is the tube that conducts air, it has noncollapsible walls, due to presence of cartilaginous C-shaped rings, it is mainly hyaline cartilage. Trachea enters into lungs after branching into bronchus, it further divides into bronchioles. Branchioles do not have cartilaginous rings. Bronchi walls are supported by cartilaginous rings.

The lungs of human comprises
1 Bronchi
2 Bronchioles
3 Alveoli
4 All of these
Explanation:

Lining of trachea is made of
1 Simple squamous epithelium
2 Simple cuboidal epithelium
3 Pseudo stratified epithelium
4 Stratified cuboidal epithelium
Explanation:
The trachea is lined with ciliated pseudostratified columnar epithelium, a type of epithelium with goblet cells that produce mucins, the main component of mucus, to moisten and protect the airways from foreign particles. This type of epithelium can easily sense foreign particles and ciliary movement remove the particles.
