Foundations
Topics 1.1 to 1.10
Build the internal environment, its borders, signals, electrical language, and movement.
Subject 01 · Semmelweis
Physiology I
Blocks 1 to 5, followed in the university sequence and connected through one physiological storyline.
The narrative map
The internal environment becomes a living system.
Foundations explain the rules. Circulation moves blood. Respiration exchanges gases. The kidneys regulate the environment. Blood completes the system through production, hemostasis, coagulation, and identity.

The university map stays visible.
Circulation
Topics 2.1 to 2.12
Set blood in motion, generate pressure, and distribute flow according to need.
Respiration
Topics 3.1 to 3.5
Bring the atmosphere to the blood and carry carbon dioxide back out.
Renal physiology
Topics 4.1 to 4.5
Filter the internal environment, recover what matters, and regulate volume, osmolality, and pH.
Blood
Topics 5.1 to 5.4
Understand how blood is produced, protected from loss, and defined by biological identity.
