UCLA LS 7C: Physiology and Human Biology
LS 7C is the final course in UCLA's Life Sciences core, covering the organization of cells into tissues and organs and the physiology of the major organ systems, with an introduction to human genetics and genomics. It completes the 7-series and is the bridge to upper-division physiology and pre-health coursework.

What makes it hard
The volume of integrated systems detail is the difficulty: each organ system layers structure, function, and regulation, and the systems interconnect in ways exams probe with whole-body scenarios. The flipped format front-loads the work, and the pre-med-heavy cohort keeps the curve competitive on a ten-week clock.
What you'll cover
- • Tissue and organ organization
- • Cardiovascular and respiratory physiology
- • Renal and digestive systems
- • Endocrine and nervous system regulation
- • Homeostasis and feedback
- • Human genetics and genomics
The LS 7C study guide
How to study for UCLA LS 7C, step by step.
- 1
Never skip the pre-class videos
LS 7C's flipped format front-loads the work: unprepared students get nothing from the in-class sessions. Watch the videos and finish pre-class assignments before every meeting.
- 2
Map each organ system as structure, function, regulation
The volume is unmanageable as raw notes. Reduce each system to a one-page diagram covering what it does, how it's controlled, and how feedback keeps it stable, then study from the maps.
- 3
Practice whole-body integration scenarios
Exams favor questions where one system perturbs another: drop blood pressure, predict the renal and cardiovascular response. For each system, rehearse how it responds to disturbances in the others.
- 4
Study from the learning objectives
Exam questions map to the published objectives. Convert each into a question you can answer from memory to build the exam blueprint directly.

FAQ
Is LS 7C hard at UCLA?
The difficulty is volume and integration rather than conceptual depth: each organ system carries dense detail, and exams probe how the systems interact. Students who map each system and practice integration scenarios fare better than pure memorizers on the competitive curve.
How should I study for LS 7C exams?
Reduce each organ system to a structure-function-regulation map, study from the learning objectives, and rehearse whole-body scenarios where one system disturbs another. The exams favor integration questions over isolated recall.
Does LS 7C complete the Life Sciences core?
Yes. LS 7A, 7B, and 7C together form UCLA's Life Sciences core sequence, after which students move into upper-division coursework for their specific major. LS 7C's physiology foundation is especially relevant for pre-health tracks.
More UCLA courses
LS 7A: Cell and Molecular Biology
LS 7A is the first course in UCLA's Life Sciences core, covering cell structure, energy and metabolism, the central dogma, and cell signaling. It's the gateway for every life-science major and the pre-med masses, taught flipped-classroom style with pre-class videos and in-class active learning.
LS 7B: Genetics, Evolution, and Ecology
LS 7B is the second course in UCLA's Life Sciences core, covering Mendelian and population genetics, the mechanisms of evolution by natural selection, and population, behavioral, and community ecology. Like the rest of the 7-series it's taught flipped-classroom, with pre-class videos feeding in-class active learning.
