Human Physiology Instruction.
Human physiology is the integrated science of how the body actually works — every organ system as a set of controlled variables, feedback loops, and cellular mechanisms. It is one of the most important pre-medical courses.
Vinai Sharma teaches physiology as an integrated system — organ by organ, with homeostasis as the through-line — so that structure, biochemistry, and pathophysiology finally make sense together.

Section 01
Course Overview
Physiology is unified by homeostasis — the idea that every system in the body maintains a controlled variable through feedback loops.
The course covers every major organ system in humans — nervous, endocrine, cardiovascular, respiratory, renal, digestive, musculoskeletal, and reproductive — with the depth pre-medical, nursing, and MCAT preparation actually require.
Every system is taught with the same structure: organ layout, cellular physiology, integrated function, and pathophysiology — so students see physiology as one coherent science rather than eight separate memorization units.

Problem-Solving Fluency
Breaking multi-step problems into manageable, repeatable moves.
Precise Notation & Language
Writing arguments cleanly enough that another mathematician or scientist can follow them.
Quantitative Reasoning
Choosing the right structure and estimating whether an answer is plausible.
Independent Study Habits
Reading a textbook, working through examples, and self-checking without a teacher present.
Exam Readiness
Sustained accuracy under timed conditions, on both school exams and standardized tests.

Why Human Physiology Matters
Why this course is one of the highest-leverage academic investments a family can make.
Pre-Medical Foundation
Every medical school assumes a strong physiology background.
Nursing & Allied Health
Physiology is the core science of nursing and allied-health training.
MCAT Content
Physiology appears throughout the Bio/Biochem and Psych/Soc sections of the MCAT.
Clinical Reasoning
Understanding disease requires understanding normal physiology first.
TEAS & HESI Preparation
Physiology is a major content area on both nursing entrance exams.
Sports & Exercise Science
Exercise physiology, cardiology, and sports medicine all build on this foundation.
Section 07
Connections to Other STEM Subjects
How Human Physiology connects to the rest of the Vinai Sharma curriculum — the courses it prepares students for, and the exams it supports.
Biology
Physiology extends the general-biology body-systems unit to full mechanistic depth.
Biochemistry
Every organ system has a characteristic metabolic profile.
Cell Biology
Every physiological function is a cellular function — the two courses reinforce each other.
MCAT
Physiology is one of the largest content areas on the exam.
TEAS & HESI
Physiology is a major section on nursing entrance exams.
Pharmacology
Drug action makes sense only against a physiological baseline.
