Whereas humans have lungs with _____(a)_____ for gas exchange, sharks have _____(b)_____ with  _____(c)_____.(a) alveoli (b) capillaries (c) lamellas(a) alveoli (b) gills (c) lamellas(a) tracheas (b) gills (c) lamellas(a) capillaries (b) lungs (c) lamellas

Question 6SavedContinuing from the previous question, compare shark lamellas and alveoli in humans.

Gas exchange between the inspired air and the blood occurs at the ______ of the lungs.Multiple choice question.alveolirespiratory bronchiolestracheaprimary bronchi

Gas exchange between air in the alveoli and blood in pulmonary capillaries is called Blank______.Multiple choice question.cellular respirationinternal respirationexternal respiration

Determine whether this comparison is true.Human respiratory systems take in air through the nostrils and mouth and expel it back out the same way. Sharks are the same except for them it is water moving in and out. TrueFalseI'm not sure

Sharks exchange oxygen and carbon dioxide with sea water across the surfaces of millions of tiny lamellas in their gills.Explain why they need so many lamellas.
