VCCS Course Description
Presents an integrated approach to human anatomy and physiology, microbiology and pathology.
Includes chemistry and physics as related to health sciences. Lecture 3 hours per week.
Recitation and laboratory are 3 hours each per week. Total 6 hours per week. Part I of II. Part II

General Course Purpose
NAS 161-162 is a college transfer-level course designed to meet the needs of students pursuing
programs in various health technology fields. The course consists of formal lectures,
demonstrations and laboratory activities, which examine the microscopic and gross anatomy of
the systems of the human body and their physiology. Microbiology and pathology are integrated
and emphasis throughout is on integrated operation of the body systems. This course is a
requirement of many of the health technology curricula and may be completed prior to entry into
the curriculum of choice.
