This document outlines the content to be covered in a senior biology class at Colegio Las Cumbres. It includes three main topics over three trimesters: nutrition in humans covering respiration, gas exchange, and transport; human physiology covering blood, pathogens, the endocrine system, and blood glucose control; and homeostasis covering temperature regulation, excretion, and kidney function. Specific sub-topics are listed under each main content area, such as the structures involved in respiration, breathing, and gas exchange as well as aerobic and anaerobic respiration equations.
