Question

Сравните анатомическое строение сердца лягушки и ящерицы. Пожалуйста!!!

Answer 1

У лягушки трехквмкрное( 2 предсердия, 1 желудочек) один крук кровообращения, четырехкамерное(2 желудочка, 2 предсердия) и 2 круга кровообращения-малый и большой.

Answer 2

Лягушка это земноводное поэтому у неё сердце трёхкамерное и кровь смешивается, а ящерица это пресмыкающееся и у неё сердце трёхкамерное с неполной перегородкой, кровь частично смешивается

Answer 3

Comparative Anatomy of Frog and Lizard Hearts

The anatomical structure of the heart in frogs and lizards differs in several key aspects. Let's compare the two:

Frog Heart Anatomy: - Frogs have a three-chambered heart consisting of two atria and one ventricle. - The right atrium receives deoxygenated blood from the body and transfers it to the ventricle. - The left atrium receives oxygenated blood from the lungs and transfers it to the ventricle. - The ventricle pumps blood out of the heart, sending deoxygenated blood to the lungs and oxygenated blood to the body. - The frog heart has a partially divided ventricle, which helps to separate oxygenated and deoxygenated blood to some extent. - The blood flow in the frog heart is not completely separated, resulting in some mixing of oxygenated and deoxygenated blood.

Lizard Heart Anatomy: - Lizards have a three-chambered heart similar to frogs, but with some variations. - The right atrium receives deoxygenated blood from the body and transfers it to the ventricle. - The left atrium receives oxygenated blood from the lungs and transfers it to the ventricle. - The ventricle pumps blood out of the heart, sending deoxygenated blood to the lungs and oxygenated blood to the body. - Unlike frogs, some lizards have a completely divided ventricle, which helps to separate oxygenated and deoxygenated blood more effectively. - The blood flow in the lizard heart is better separated compared to frogs, reducing the mixing of oxygenated and deoxygenated blood.
