Physiology-insights into human physiology

Example

The regulation of blood glucose levels by insulin and glucagon.

Scenario

In a scenario where a person consumes a meal high in sugar, physiology explains how the pancreas releases insulin to lower blood sugar levels, and how it later releases glucagon to increase it when levels drop, ensuring the body’s glucose levels remain stable.

Example

The cardiovascular system’s interaction with the respiratory system.

Scenario

During exercise, physiology examines how the heart increases its output to pump more oxygenated blood throughout the body, and how the respiratory rate increases to supply the needed oxygen, illustrating the collaboration between these systems to meet the body's increased demands.

Example

The fight-or-flight response triggered by the sympathetic nervous system.

Scenario

In a dangerous situation, such as encountering a predator, physiology explores how the body responds by increasing heart rate, dilating pupils, and redirecting blood flow to muscles, preparing the individual for immediate action.
