This is my presentation from my Anatomy & Physiology II (Bio 172) class at SUNY - Onondaga Community College. This lecture on Thursday, March 22, 2012 was during Unit 3 of the course. I discuss the life cycle of an erythrocyte (RBC), including how it is degraded after about 120 days and also begin explaining different blood types. You can contact me through YouTube or by email (jroufaiel@gmail.com) with questions.
