Learning Objectives

The course allows the student to acquire the knowledge about the vital functions of man and the cellular mechanisms of the major biological systems. It analyzes the integrated functioning of the different organs and systems of control by which the living organism obtains and maintains the homeostasis inside.


Course Structure

During the course of the lessons there will be written tests and oral interviews in the appeals indicated in the exam calendar. About it, the student will receive a pdf of some topics covered in class.
