A comprehensive introduction to key biological concepts tested on the MCAT, focusing on cellular processes, genetics, and the integration of biological systems.
The human body is made up of many organ systems that must communicate and coordinate for healthy function.
The nervous system uses electrical signals, while the endocrine system uses hormones to regulate body processes.
These systems work together to deliver oxygen and nutrients to tissues and remove waste.
Protects the body from pathogens using a complex network of cells and molecules.
Understanding system integration is vital for diagnosing diseases and developing treatments that target multiple systems.
Adrenaline released during stress affects both the heart and lungs.
Diabetes impacts both endocrine and circulatory systems.
