Question

В чем сходство и различие кровеносной системы позвоночных животных?​

Answer 1

Ответ:

1. Кровеносная система у млекопитающих и земноводных замкнутая;

2. Млекопитающие и земноводные имеют 2 круга кровообращения.

Различия:

1. У млекопитающих у четырекамерное сердце, а у земноводных - трехкамерное.

2. У земноводных кровь смешивается, а у млекопитающих - нет (артериальная и венозная кровь).

3. Земноводных считаются холоднокровными животными, а млекопитающие - теплокровными.

Объяснение:

Answer 2

Similarities and Differences in the Circulatory System of Vertebrate Animals

The circulatory system in vertebrate animals, including mammals, birds, reptiles, amphibians, and fish, shares several similarities and differences.

Similarities: 1. Basic Structure: The circulatory system in vertebrates consists of a heart, blood vessels, and blood. - Source: - "IX. (2). - , , . IX. (1)..." - Source: - " , . , . , . (, , ), , . . \(11\)."

2. Function: The primary function of the circulatory system in vertebrates is to transport oxygen, nutrients, hormones, and waste products throughout the body. - Source: - " , , , . .. . . . , 1960 1- ."

Differences: 1. Heart Structure: While all vertebrates have a heart, there are differences in the number of chambers within the heart. For example, mammals and birds have a four-chambered heart, while fish have a two-chambered heart. - Source: - "... . 1...01.03 . 1...01.03 ... , ..."

2. Circulation Type: Vertebrates exhibit variations in the type of circulation. For instance, mammals and birds have a double circulation system (pulmonary and systemic circulation), while fish have a single circulation system. - Source: - "... , ..."

3. Blood Composition: The composition of blood can vary among vertebrates. For example, some fish have nucleated red blood cells, while mammals have non-nucleated red blood cells. - Source: - "... , ..."

4. Respiratory Surfaces: The location and structure of respiratory surfaces, such as gills in fish and lungs in mammals, differ among vertebrates. - Source: - " , , ... ? ..."

In summary, while the circulatory system in vertebrate animals shares a basic structure and function, there are notable differences in heart structure, circulation type, blood composition, and respiratory surfaces. These variations reflect the diverse adaptations of vertebrates to their environments and lifestyles.
