Basic Structures & Functions of the Human Body

1. Basic Structures & Functions of the Human Body

The human body is made up of various structures which aid its biological functions in survival. Learn more in a comparison of the human body and cities, structures of the body, and interactions of human organs in the body.

Functions of the Nervous System

2. Functions of the Nervous System

The nervous system helps animals interact with their respective environments. Learn more about how the nervous system functions to collect input from the body's senses and external environment, processes and interprets sensory input, and responds appropriately to the sensory input.

The Structure and Function of Neurons

3. The Structure and Function of Neurons

The structure of neurons contains two main components, dendrites and axons, that polarize and depolarize cells. Those two components are responsible for the function of sending signals among cells. This lesson extrapolates on those elements, in addition to synapses, and it also explores polarization and depolarization processes.

The Central and Peripheral Nervous Systems

4. The Central and Peripheral Nervous Systems

The central nervous system is composed of the brain and spinal cord, while the peripheral nervous system is composed of the sensory and motor neurons of the body. Discover how sensory neurons, such as photoreceptors and thermoreceptors, collect sensory input and sent it to the brain, as well as how motor neurons transmit signals to responsive tissues to appropriately respond to a situation.

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.

Innate Immunity: Inflammation, Neutrophils & Natural Killer Cells

6. Innate Immunity: Inflammation, Neutrophils & Natural Killer Cells

The innate immune system builds a defense against dangerous pathogens and other foreign invaders of the body. Explore the innate immune system and discover the functions of various immune cells, like neutrophils, which are the first immune cells to respond to wounds.

Acquired Immunity: T Cells, B Cells and Antibodies

7. Acquired Immunity: T Cells, B Cells and Antibodies

People who have acquired immunity against an illness cannot be infected with it again. Discover how T cells, B cells, and antibodies work together to fight illnesses in this lesson.

Infectious Agents: Viruses, Viroids & Prions

8. Infectious Agents: Viruses, Viroids & Prions

Infectious agents are nonliving organisms that can cause illness when attached to a living host cell. In this lesson, explore the world of viruses, viroids, and prions and how they operate as infectious agents.

Overview of Human Reproduction

9. Overview of Human Reproduction

This lesson will provide a general overview of the process of human reproduction. We will cover the basics starting from the point of fertilization through the point of birth.

Human Development Stages From Infancy to Late Adulthood

10. Human Development Stages From Infancy to Late Adulthood

Human development is the process in which a person grows from an infant into an adult. Explore the different stages of growth like infancy, childhood, adolescence and early, middle and late adulthood.
