1. What Is an Organ System? - Definition & Pictures
In this lesson, you will learn what an organ system is, and you will review each organ system in the human body. This will aid in your study of human anatomy and physiology. At the end of the lesson, a quiz will test your knowledge.

2. Animal Tissues: Types, Structure & Function
Ever use tissues? Well, your body certainly does! Actually, four different kinds! They are the epithelial tissue, muscle tissue, nervous tissue, and connective tissue. This lesson goes over the basics of these tissues.

3. Using Feedback Systems to Regulate Growth, Reproduction & Dynamic Homeostasis
In order to maintain specific internal conditions, organisms use feedback mechanisms. Feedback is essential to the regulation of internal environments, which allows for proper biological functioning.

4. Homeostasis and Adaptation to Stress
Homeostasis can seem complicated, but really it's just a balancing act. This lesson will look at how stress can affect us and the important part it plays in maintaining homeostasis.

5. Homeostasis and Temperature Regulation in Humans
Do you wonder how your body is able to maintain a consistent temperature? Have you ever questioned why you get goosebumps when you're cold? This lesson will introduce you to homeostasis and answer your questions about body temperature regulation and reactions, like goosebumps.

6. Energy Balance: How the Body Uses Energy
Energy balance is the relationship between the energy you take in and the energy you use. Learn how you take in energy from the foods you eat and how your body uses that energy for your basal metabolism, physical activity and food digestion.
