Canine physiology

Canine physiology refers to how a dog's body functions. It includes systems like the cardiovascular system, which pumps blood; the respiratory system, which supplies oxygen; the digestive system, which processes food; and the nervous system, which controls movement and sensation. Dogs have a keen sense of smell and hearing, and their bodies are designed for activity and survival. Their immune system fights infections, while their muscles and bones support movement. Overall, a dog's physiology is a complex, integrated system that maintains health and responds to environmental needs.
