Answer 1

${ \huge \bf { \mid{ \overline{ \underline{Answer}}} \mid}}$

The incorrect Statement in the Above question is :-

Neural signals from pneumotoxic centre in pons region of brain can increase the Respiratory rate.

$\huge{\bold{\underline{Explanation:-}}}$

Checking Each and Every Option.

Statement - 1

Cigarette smoking may lead to inflammation of bronchi.

• This disease is commonly referred as Emphysema. It's caused due to Excessive Cigarette smoking .

• It is a Chronic Disorder .

• The walls of Alveoli loose their Elasticity, due to which Surface area for Exchange of gases is reduced.

• This condition is called Inflammation of Bronchi.

Therefore, The Statement - 1 is Correct.

Statement - 2

Neural signals from pneumotoxic centre in pons region of brain can increase the Respiratory rate.

• Pneumotoxic centre is Present in the Pons region of Hind brain.

• Pneumotoxic centre Moderates the Function of Respiratory Rhythm Centre(Located in Medulla region of Hind brain).

• The Neural signals from Pneumotoxic centre can Reduce the Duration (or) Timing of Inspiration(Inhalation) and thus reduces the Respiratory rate.

Therefore, The Statement - 2 is wrong.

Statement - 3

Workers in grinding and stone - breaking industries may suffer from Lung fibrosis.

• It's a occupational Respiratory disorder.

• It's a disease of Lungs due to inhalation of Dust (or) Mineral dust , which is commonly called as lung fibrosis.

• Silicosis & Asbestosis are the lung fibrosis caused by inhalation of silica & Asbestos dust.

Therefore, The Statement - 3 is correct.

So, Option - (b) is the wrong statement According to Human respiration.

Answer 2

Answer:

b)Neural signals from pneumotaxic centre in pons region of brain can increase the respiratory rate.✔ that's the wrong in case of human respiratory.
