The image shows the circulation of blood in fishes and humans. How is the circulations of blood in fish different from that in humans
Answers
Answer:
In a closed circulatory system, blood is contained inside blood vessels and circulates unidirectionally from the heart around the systemic circulatory route, then returns to the heart again. Fish have a single circuit for blood flow and a two-chambered heart that has only a single atrium and a single ventricle.
Explanation:
Answer:
Fish have two chambers what is known as single circulation, whereas humans have double circulation because their hearts have four chambers.
Explanation:
The blood circulation in fishes :
Venous circulation refers to the process through which the heart of a fish gets blood from veins and sends it to the gills for oxygenation. Due to their two chambered hearts, fish only have one circulation.
The blood circulation in humans :
The human circulatory system circulates blood twice, once for oxygenated blood and again for deoxygenated blood (double circulation).Two ventricles and two arcuate chambers make up the four chambers of the human heart.
There are so many differences. That are :
- Warm-blooded creatures include humans. However, fish are cold-blooded creatures.
- Systemic and pulmonary circulation are both present in the human body. Fish only have one type of circulation, called systemic circulation.
- Human lungs experience gaseous exchange. Within the fishes' gills, there is gas exchange.
- Humans have double circulation because their hearts have four chambers, but fish have two chambers and what is known as single circulation.
