Live HS
Human Physiology and Dignity with Lab, Part One

This challenging, college-preparatory course focuses on human physiology in the context of human dignity as taught by the Catholic Church. Fundamentals of Catholic bioethics are taught with physiology and incorporated into case studies and labs. This course is excellent preparation for anyone interested in further pursuing education in biology, medicine, or allied health.

Total classes: 29

Prerequisite: Required: High school biology. Strongly recommended: High school chemistry.

Suggested grade level: 11th to 12th grade 

Suggested credit: One full semester Honors Biology with Lab 


Students will learn about human physiology and Catholic bioethics in the context of health and disease. We will meet for 75 minutes per class, twice per week; of the 150 minutes each week, 30 minutes are for lab. An additional required 50 minutes (approximately) of weekly video lectures based on the readings are also required. The course has two one-week breaks scheduled. Class time is spent discussing the readings and video content, not lecturing, during which student participation is expected. Students will complete weekly quizzes and 2 exams. Classes during exam week are preparatory reviews. Students need to be in a distraction-free environment during all live classes and are strongly encouraged, though not required, to be on camera during discussions. Students will be required to be on camera during exams, which the instructor will monitor.
