What Is an Organ System? - Definition & Pictures

1. What Is an Organ System? - Definition & Pictures

The internal organs of a human body can be grouped according to their functions; an organ system is the collective term for these similar organs. Explore the different organ systems inside the human body--such as the nervous system and endocrine system--and their functions.
Animal Tissues: Types, Structure & Function

2. Animal Tissues: Types, Structure & Function

The bodies of organisms in the animal kingdom are made up of different types of tissues. Learn about the different types of tissues, such as the epithelial tissue, muscle tissue, nervous tissue, and connective tissue, and understand their structure and functions.
Using Feedback Systems to Regulate Growth, Reproduction & Dynamic Homeostasis

3. Using Feedback Systems to Regulate Growth, Reproduction & Dynamic Homeostasis

A feedback system is a mechanism where a given action is triggered by another activity or process often assisting growth and reproduction. Discover the impact of feedback systems in biological homeostasis through feedback mechanisms, negative feedback, positive feedback, and alterations.
Homeostasis and Adaptation to Stress

4. Homeostasis and Adaptation to Stress

When it comes to mental health, homeostasis is the ability to maintain a stable psychological state despite varying stressors. Explore examples of how stress affects human beings, learn how people adapt to it, and discover how solution-focused coping can help.
Homeostasis and Temperature Regulation in Humans

5. Homeostasis and Temperature Regulation in Humans

Humans, as well as other mammals and birds, need a stable body temperature. Learn how temperature is regulated in humans by exploring homeostasis, thermoregulation, and hypothalamus, and also understand the difference between endotherms and ectotherms.
Energy Balance: How the Body Uses Energy

6. Energy Balance: How the Body Uses Energy

Energy balance is the important relationship between the energy the body takes in and the energy the body puts out. In this lesson, explore how the body uses energy, planned physical activity vs. non-exercise activity thermogenesis, and the thermic effect of food.
