Differences between rat, mouse and human organs

The main differences between rats, mice and human organs are as follows:

1. heart rate: the heart rate of mice can reach 600 bpm, the heart rate of rats drops to about 300 bpm, and the heart rate of people is about 70 bpm.

2. Genome: From the genome point of view, the genome of mice is 2.6 billion pairs, that of rats is 2.75 billion pairs, and that of humans is 2.9 billion pairs.

3. Chromosomes: Mice have 20 pairs of chromosomes, rats and humans have 2 1 and 23 pairs of chromosomes respectively.

4. Size: The size of rats and mice is very different from that of humans, ranging from a few centimeters to dozens of centimeters, while the average height of humans is about 1.5 meters.

5. Anatomical structure: The anatomical structure of rats and mice is also very different from that of humans. For example, mice have smaller and simpler brains and simpler respiratory systems.

6. Physiological function: There are some differences between rats and mice and humans. For example, mice have faster metabolism and can digest food and produce energy faster. The reproductive cycle of mice is also much shorter than that of people.

Generally speaking, although there are similarities between rats and mice and humans, there are obvious differences in heart rate, genome, chromosome, size, anatomical structure and physiological function.
