EHS 2110: HUMAN ANATOMY, PHYSIOLOGY AND MICROBIOLOGY

INTRODUCTION

 Human Anatomy, Physiology and Microbiology course is aimed to equip students with the relevant biomedical knowledge to enable them to understand factors related to environmental health. Environmental Health practitioners should be knowledgeable of the causative agents of human (and animal originated) communicable diseases and their effects on public health in order to commission control measures.

 

COURSE AIM

HUMAN ANATOMY, PHYSIOLOGY AND MICROBIOLOGY is meant to demonstrate relevant biomedical knowledge related to environmental health in the control of communicable and non-communicable diseases.

COURSE OBJECTIVES

At the end of this course, students should be able to:

1.      Outline functions of all organs of the human body

2.      State the immune response, immune disorders and their consequences.

3.      Describe the life cycle of selected parasites of medical importance, the pathogenesis of the diseases they cause and parasites using the appropriate microscopic techniques.

4.      Describe the structure of bacteria and its growth

5.      State the basic mechanisms of microbial pathogenicity and host resistance

COURSE COMPETENCIES

 

1.      Explain functions of all organs of the human body
