PLTW HBS Final Exam Review 2026 (HBS-101) – 110 Questions & Answers on Anatomy, Physiology, Genetics, Body Systems – Project Lead The Way

This document provides a comprehensive set of approximately 110 exam-style questions and verified answers designed for the PLTW Human Body Systems (HBS) course. It covers a wide range of foundational topics including anatomy (skeletal structure, muscles, organs), physiology (respiratory, circulatory, digestive, and endocrine systems), genetics (DNA, RFLP, enzymes), neuroscience (brain regions, neurons, reflex arcs), and homeostasis. The structured Q&A format supports active recall and reinforces understanding of key biological concepts. The content is aligned with PLTW curriculum standards and commonly supported by textbooks such as Principles of Anatomy and Physiology by Tortora & Derrickson, which is frequently used alongside HBS coursework. As seen throughout the document (pages 1–13), it integrates definitions, applied questions, and system-based knowledge, helping students connect theory to practical understanding of the human body. This resource is ideal for high school students enrolled in PLTW Human Body Systems (HBS), pre-health and biomedical science programs, and introductory anatomy and physiology courses. It is also useful for students preparing for final exams, health science certifications, or pursuing future studies in nursing, medicine, physical therapy, or biomedical fields. Additionally, it supports learners interested in forensic science, kinesiology, and general biology who require a strong foundation in human body systems.
