What similarity is observed in the structure of respiratory system and alimentary canal with respect to their function
Answers
Answer:
Explanation:
The pharynx is a five-inch long tube that starts near our nose and ends at our windpipe. The pharynx is generally considered a part of the throat in both vertebrate and invertebrate animals. In humans, it is a hollow structure (or muscular cavity) lined with moist tissue. This is typical of all structures within our alimentary and digestive tracts. Having a moist lining with a mucus rich barrier allows us both to breathe and for our food to travel safely through our canal without damaging our sensitive tissues. The muscular pharynx effectively forms the entry for the esophagus, or our “food canal,” and the trachea, also known as our “windpipe.” For this reason, the pharynx is considered a part of both our respiratory and digestive systems.
In phrynx, windpipe and oesophagus are attached. They are separated by epiglottis. Epiglottis is a slab like structure which covers the windpipe when we engulf food.
