Question

What animal is used most often as an example of human body systems?

Answer 1

The animal most often used as an example for human body systems is the rat, particularly the laboratory rat. Rats are commonly used in scientific research and education due to their biological and physiological similarities to humans. They serve as models in studies related to anatomy, organ systems, disease mechanisms, and drug testing, making them a popular choice for illustrating human body systems. Other animals like pigs and monkeys are also used in certain contexts, but rats are the most ubiquitous in basic biology and physiology education.
