BIOL 203 - Anatomy & Physiology II
4 Credit: (3 lecture, 2 lab, 0 clinical) 5 Contact Hours: [BIOL 202 ]
This continuation of BIOL202 covers the digestive system, the endocrine system, the respiratory system, blood, the cardiovascular system, the lymphatic system, the urinary system, water and electrolyte balance, the reproductive system and human genetics. Laboratory exercises are performed throughout the semester and related clinical applications and pathophysiology are discussed when appropriate. Homeostatic mechanisms pertinent to current lecture topics are emphasized and the course offers the opportunity to observe a human cadaver.
OFFERED: every semester
