You'll embark on a fascinating journey to understand how your body works, from the smallest cells to the complex interactions of organ systems.

The bulk of the course will focus on the different organ systems and how they contribute to overall body function. Here are the systems you'll likely study:

 * Nervous System : This includes the structure and function of neurons, nerve impulse transmission, the central nervous system (brain and spinal cord), the peripheral nervous system, sensory systems (vision, hearing, taste, smell, touch), motor control, and possibly topics like consciousness, learning, and memory.

Cardiovascular System: This section covers the heart, blood vessels, blood composition and function, blood pressure regulation, blood flow, and the circulatory system's role in transporting oxygen, nutrients, and waste products.

 * Respiratory System: You'll study the mechanics of breathing, gas exchange between the lungs and blood, transport of oxygen and carbon dioxide in the blood, and the regulation of respiration.

 * Digestive System: This includes the breakdown and absorption of food, the structure and function of the organs of the digestive tract (mouth, esophagus, stomach, intestines), the roles of digestive enzymes, and the liver and pancreas.
