Question

what is the role of epiglottis and diaphragm in respiration

Answer 1

Epiglottis is a flap like structure which marks the opening of the wind pipe. It prevents food from entering the wing pipe.
Diaphragm adjusts it's shape (expand and contract) for inhalation and exhalation.

Answer 2

Answer:

• Epiglottis allows air to pass through the larynx and the respiratory system.
• The diaphragm in the respiratory system is the dome-shaped sheet of muscle that separates the chest from the abdomen.

Explanation:

• The epiglottis is a flap-like structure found in the throat. This is the covering that lies above the trachea and regulates the flow of air and food towards their respective channels while also preventing food from entering the respiratory system.
• The epiglottis is a protective membrane that surrounds our windpipe. It prevents food and liquid from entering the airway.
• When air is taken in and out, this flap opens. This permits air to pass via the tracheal system.
• In the abdomen, the diaphragm is a membrane structure.
• During inspiration, this structure flattens down, which serves to expand the thoracic cage's capacity. This permits the inhalation of air.
• The diaphragm takes on a dome-shaped form during expiration.
• This helps to pump CO2 out of the lungs by reducing the capacity of the thoracic cage.
