The pharynx is part of both the digestive and respiratory systems.
The pharynx is part of both the digestive and respiratory systems.
The pharynx, also known as the throat, is a tube used by both the digestive and respiratory systems.
the respiratory system provides O2 to cells in the digestive system which lets them liveI don't know, just Google it!
The digestive system breaks food into various nutrients.
Pharynx
The respiratory system brings in oxygen from the air, which is used by cells in the process of producing energy in the form of adenosine triphosphate (ATP). The circulatory system then transports this oxygen through the blood to the cells where it can be used in cellular respiration to generate energy.
The respiratory system provides oxygen so the body can "burn" (oxidize) the food that is brought into the body through the digestive system. The circulatory system brings nourishment to all cells of the body. The circulatory system exchanges critical gases with the respiratory system; unneeded carbon dioxide is exchanged for much needed oxygen.
The pharynx (and the glottis flap) in the throat are used by both systems, i.e. to swallow food and to breathe.
Yes, but they're not identical. The mucus lining the respiratory system is used as a dirt (well, dust) trap. The mucus lining the digestive system acts as a barrier to the digestive juices (so that you don't try to digest yourself [see 'ulcers' as example of failure]).
Both forms have a single Body_orificeand body cavity that are used for digestion and Respiration_(physiology), so yes, cnidarians do have a respiratory system.
