Circulatory system - Amphibians, Blood Vessels, Heart | Britannica
2024年9月12日 · Circulatory system - Amphibians, Blood Vessels, Heart: Modern amphibians are characterized by the flexibility of their gaseous exchange mechanisms. Amphibian skin is moistened by mucous secretions and is well supplied with blood vessels. It is used for respiration to varying degrees.
Beyond the Mammalian Heart: Fish and Amphibians as a Model …
2015年12月23日 · In this review we present the major findings from recent research on the underlying mechanisms of fish and amphibian heart regeneration. We also discuss the tools and techniques that have been developed to answer these important questions.
The vertebrate heart: an evolutionary perspective - PMC
2017年9月14日 · The amphibian heart. Amphibians (Class Amphibia, Superclass Tetrapoda) evolved significantly during the Carboniferous period around 350 Mya (Bridgewater, 2012) and show many similarities in heart structure with lungfish.
12.12: Amphibian Structure and Function - Biology LibreTexts
Amphibians have a relatively complex circulatory system with a three-chambered heart. Their nervous system is also rather complex, allowing them to interact with each other and their environment. Amphibians have sense organs to smell and taste chemicals. Other sense organs include eyes and ears.
Heart | Structure, Function, Diagram, Anatomy, & Facts | Britannica
3 天之前 · In animals with lungs—amphibians, reptiles, birds, and mammals—the heart shows various stages of evolution from a single to a double pump that circulates blood (1) to the lungs and (2) to the body as a whole. In humans and other mammals and in birds, the heart is a four-chambered double pump that is the centre of the circulatory system.
The Amphibian Heart - PubMed
Amphibians have 3 heart chambers: 2 atria and 1 ventricle. Their heart anatomy, histology, and physiology are reviewed. The basic morphology of the heart is similar in all amphibians with some differences due to their lifestyle.
Amphibian heart diseases are only occasionally reported and include genetic, congenital, infectious and neoplastic causes. At present, more than 8200 amphibian species are described,1 including the 3 orders Anura (frogs and toads), Caudata (salamanders and newts), and Gymnophiona (caecilians).
