The trachea is part of the windpipe providing a passageway for inhaled air from mouth and nostrils to lungs. It constitutes an essential component of a frog's respiratory system and connects the glottis to the lung alveoli.
Much like humans, frogs have a respiratory system that is designed for efficient transport of oxygen from the mouth to lungs. The trachea is an essential component of that system serving the role of connecting the and glottis to lung alveoli. The alveoli are the site of exchange of oxygen and carbon dioxide between blood and air in lungs. Unlike humans, frogs are capable of breathing through their skin and are not as dependent on the respiratory tract for survival as humans.Learn More
The frog heart has three chambers, two atria that take blood from the body and one ventricle to pump it out, according to the University of Wisconsin-La Crosse's Zoo Lab.
