Human Anatomy and Histology

Final Exam

Course Introduction

Human Anatomy and Histology explores the structure and organization of the human body from both macroscopic and microscopic perspectives. The course covers the major organ systems, their anatomical features, and physiological significance, with a detailed examination of tissues at the cellular level. Through lectures, laboratory sessions, and hands-on activities, students gain an integrated understanding of how organs and tissues function together to maintain homeostasis, laying a strong foundation for further study in health and biomedical sciences.
