Digestive System

Regulatory Mechanisms

Regulatory mechanisms are crucial for maintaining homeostasis, including temperature regulation, pH balance, and glucose levels, with the human body maintaining a constant temperature of around 37°C.

Ecology

Ecology examines the interactions among organisms and their environment, covering ecosystems, food chains, biogeochemical cycles, and biodiversity—key to addressing environmental challenges.
