MCAT Biology
A comprehensive introduction to key biological concepts tested on the MCAT, focusing on cellular processes, genetics, and the integration of biological systems.
Human Body Systems Integration
How Systems Work Together for Survival
The human body is made up of many organ systems that must communicate and coordinate for healthy function.
Nervous and Endocrine Systems
The nervous system uses electrical signals, while the endocrine system uses hormones to regulate body processes.
Circulatory and Respiratory Systems
These systems work together to deliver oxygen and nutrients to tissues and remove waste.
Immune System
Protects the body from pathogens using a complex network of cells and molecules.
Medical Connections
Understanding system integration is vital for diagnosing diseases and developing treatments that target multiple systems.
Examples
Adrenaline released during stress affects both the heart and lungs.
Diabetes impacts both endocrine and circulatory systems.
In a Nutshell
Body systems must work together to maintain health and respond to challenges.
