Cornell BIOG 1440: Introductory Biology: Comparative Physiology

BIOG 1440 is one of Cornell's introductory majors biology courses, focused on comparative physiology — how animals and plants solve the problems of survival across organ systems, from gas exchange and circulation to osmoregulation and neural signaling. It satisfies part of the intro biology requirement for life-science and pre-health students.

What makes it hard

It's not pure memorization: prelims emphasize applying physiological principles to novel scenarios — predict what happens to this system under that condition — which rewards understanding mechanisms over recalling facts. The breadth across organ systems is large, and students who study by re-reading rather than explaining how each system works hit a wall on the application questions.

What you'll cover

• Principles of physiology and homeostasis
• Gas exchange and respiration
• Circulation
• Osmoregulation and excretion
• Neural and hormonal signaling
• Comparative organ systems

The BIOG 1440 study guide

How to study for Cornell BIOG 1440, step by step.

1
Learn mechanisms, not just labels
BIOG 1440 prelims ask you to apply physiology to novel scenarios, so memorizing structures isn't enough. For each system, learn what it does, how, and what happens if a step is disrupted.
2
Self-quiz with prediction questions
Practice predicting how a system responds to a change — more salt, less oxygen, a blocked vessel — rather than rereading notes. Prediction is exactly the format the application questions take.
3
Compare systems across organisms deliberately
The comparative angle means contrasting how different animals solve the same problem. Build comparison tables so the parallels and contrasts the exams probe are explicit, not blurred.
4
Use spaced review for the breadth
The organ-system breadth is large and earlier systems resurface in integrative questions. A short weekly pass over earlier material keeps the volume from compounding into a finals-week mountain.

How Fennie helps with BIOG 1440

Fennie's Daily Plans pace BIOG 1440's organ-system breadth with spaced review so earlier systems stay sharp for the integrative questions. Generate flashcards per system and chat through prediction-style questions — how a physiology responds when conditions change — which is exactly the application format the prelims reward over memorization.

FAQ

Is BIOG 1440 at Cornell hard?

It's demanding less for volume than for its application focus: prelims ask you to predict how physiological systems respond to novel conditions, not just recall facts. Students who learn mechanisms and practice prediction do well; rereading-only studiers hit a wall.

How do I study for BIOG 1440 exams?

Learn how each system works and what happens when a step is disrupted, then self-quiz with prediction questions in that format. Build comparison tables across organisms, since the comparative angle is a frequent exam target.

Is BIOG 1440 good for pre-med?

It's a common part of the intro biology requirement for pre-health students, and its physiology foundations connect well to later coursework and the MCAT's biological systems content. Confirm your specific sequence on your degree audit.

CS 1110 — Introduction to Computing: A Design and Development Perspective

CS 1110 is Cornell's Python-based first programming course — variables and types, functions, conditionals and loops, objects and classes, recursion, and testing — taken by intended CS majors and a large non-major population alike. It leads into CS 2110 for those continuing in the major.

CS 2110 — Object-Oriented Programming and Data Structures

CS 2110 is Cornell's second programming course, taught in Java (cross-listed as ENGRD 2110) — object-oriented design, data structures (lists, trees, hash tables, graphs), recursion, and an introduction to algorithmic analysis. It's the gateway most CS and engineering students name as the major's first real workload jump.

CS 2800 — Discrete Structures

CS 2800 is Cornell's discrete mathematics course for CS majors — logic and proof, induction, sets, functions and relations, combinatorics, graph theory, basic probability, and finite-state machines. It's the bridge from coding to the mathematical reasoning the upper-level theory courses assume.

CS 3110 — Data Structures and Functional Programming

CS 3110 is Cornell's famous functional-programming and data-structures course, taught in OCaml — immutability, recursion, higher-order functions, modules and functors, formal specification and verification, and reasoning about correctness and complexity. It's a required CS core course and a notorious pace step-up after CS 2110.
