How does the structure of a frog's ventricular wall compare to it's atrial wall?

The short Answer: The ventricles have thicker walls than the atrium simply because this is the part of the heart that does most of the pumping action by contracting. It has to be strong and fairly thick to cope with the pressure.
(Ventricles have thicker walls than the atrium, which creates a higher blood pressure. The left ventricle has thicker walls because it needs to pump blood to the whole body. The wall of the left ventricle is 8-15 mm
The right atrium's wall is approximately 2mm in thickness, due to the combined influence of the low pressure of this chamber and the ease of pumping to low pressure areas)

∙ 11y agoventricle wall is thicker than atria wall as ventricle need to exert higher pressure than atria.
ventricle needs to exert higher pressure because :
(i) have to pump oxygenated blood to reach all over the body
(ii) distance travel by blood is further
on the contrary, atria has thinner wall because it only "send" blood to ventricle ( shorter distance compared to ventricle )

∙ 13y agothey are more thickned then auricle as they face more pressure while pumping blood away from then and to the distantg organ.

The walls of the ventricles are thicker than the walls of the atria. Also, the walls of the left ventricle are thicker than the walls of the right ventricle.

∙ 13y agoTh atrial walls are thin and elastic, they only need to push the blood a short distance. Whereas the ventricular walls are thick and muscly, for they need to push the blood further.

Compare and contrast systems in frogs and worms?
Frogs have a heart that has 3 chambers, and worms do not. Worms exchange gas from their blood through their skin, but frogs are not able to do this. Frogs have the same type of respiratory system as humans.
Frogs accessory structures in the nose?
Frogs have no proper nose. However, they do have nostrils which are an accessory structure for respiration since frog rely on buccal pumping (breathing with the cheeks) for respiration.
Where does a frog's glottis lead?
It leads to the frogs lungs.to the lungsThe glottis is tube-like structure in the frog's throat that leads to the larynx and then the trachea. It eventually leads to the lungs.

Why frogs are considered an ideal specimen in the study of general zoology?
err... maybe because the structure of the organs of a frog is most likely the structure & position of organs in a human's body... and frogs are easy to get or buy... and many species are not endangered! :) hopin' this can help!
