- Have limited time for studying
- Want a cost effective way to supplement their science learning
- Prefer learning science visually
- Find themselves failing or close to failing their nervous, immune and endocrine systems unit
- Cope with ADD or ADHD
- Want to get ahead in GED science
- Don't have access to their science teacher outside of class
Why it works:
- Engaging Tutors: We make learning the nervous, immune and endocrine systems simple and fun.
- Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
- Consistent High Quality: Unlike a live GED science tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn the nervous, immune and endocrine systems on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Learn how temperature and homeostasis are regulated in humans.
- Explain how hormones control glucose levels.
- Describe the structure and function of neurons.
- Understand the functions of the sympathetic and parasympathetic nervous systems.
- Take a look at the different brain structures and their functions.
- Identify the parts that comprise the brain stem.
- Differentiate between innate and acquired immunity.
- Understand how antibiotic resistance can develop.
1. 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.
2. Homeostasis of Glucose Levels: Hormonal Control and Diabetes
In this lesson, we'll look at how the body uses hormones to maintain homeostasis of blood glucose levels, what happens in people who have diabetes, and how diabetics can manage their disease.
3. Functions of the Nervous System
In this lesson, we'll watch Timmy as he plays in his backyard. Watch what happens when he tries to catch a butterfly, hears a mean dog bark, and scrapes his knee. All of Timmy's reactions are tied to his nervous system. For a full explanation of what goes on in the human nervous system, check out the video!
4. The Structure and Function of Neurons
In this video lesson, you'll learn about neurons, which are specialized cells in the nervous system. Check out how far neurons can send signals throughout the body and how depolarization is much like 'the wave' at a football game.
5. The Central and Peripheral Nervous Systems
Did you know that hammerhead sharks and platypuses share a special type of sensory neuron that humans and most other animals don't have? In this lesson, you'll find out what that sensory neuron and a whole lot of others can do. You'll also learn how the nervous system is organized and the differences between the central and peripheral nervous systems.
6. The Sympathetic and Parasympathetic Nervous Systems
In this lesson, you'll learn about two subdivisions of the autonomic nervous system - the sympathetic and parasympathetic nervous systems. Watch as a hiker, Phil, runs away from a terrifying bear and see how these systems react to the impending danger!
7. Brain Structures and Functions Part I
The brain's complexity can often be difficult to understand because it serves so many important functions. In this lesson, you'll get a little help from Nrr, the alien biologist, who will guide you through understanding the structure and functions of the human brain.
8. The Cerebral Cortex: Brain Structures and Functions Part II
Check out this video lesson to learn about the four lobes of the human brain - the frontal, parietal, occipital and temporal. You'll learn about the functions and processes of each region.
9. Innate Immunity: Inflammation, Neutrophils & Natural Killer Cells
You might already know how your body handles known infectious agents but how about unknown? Watch this video to explore your innate immune system - your body's defense against new bacteria and viruses.
10. Acquired Immunity: T Cells, B Cells and Antibodies
Have you ever wondered why some people don't ever seem to get sick? These people likely have an acquired immunity. Learn more about the immune system and how exposure to an illness one time can help your body to prevent that illness from ever occurring again.
11. Antibiotics and Vaccines
Do you know why children must get regularly vaccinated? Have you ever wondered how an antibiotic works and why they are so widely prescribed? If so, this lesson will help you to understand how changes in medicine have almost eliminated several deadly diseases and added decades to the average person's lifespan.
12. Flu Viruses, HIV and Immune System Evasion
Why is it that our immune systems can protect us from some viruses but not others? We've eradicated smallpox by using vaccines, so why do influenza and HIV remain such dangerous health risks? In this lesson about viruses, we'll explore these questions and learn how influenza and HIV continue to evade the human immune system.
13. Pathogens: Antibiotic Resistance and Virulence
Find out more about how the overuse of antibiotics could lead to some serious problems with epidemics or untreatable diseases in the future. You can also discover some of the things that make pathogens harmful and why pathogens don't cause disease in every species they infect.
14. Anatomy of the Spinal Cord: Function & Explanation
The spinal cord partners up with the brain to send information around the body as electrical signals. It tells the body what the brain wants and the brain what the body is feeling. This lesson explains how its structure helps accomplish this.
15. Dendrites: Definition & Function
Dendrites are the segments of the neuron that receive stimulation in order for the cell to become active. They conduct electrical messages to the neuron cell body for the cell to function. This lesson discusses dendrites, their function, and their importance in neuron activity.
16. What is Spina Bifida? - Definition, Types, Causes & Symptoms
Babies are sometimes born with what we call birth defects, abnormalities that can range from mild to debilitating. One of the most common is spina bifida, and it affects the spine. Learn more about spina bifida and its types, causes and symptoms.
17. Core Body Temperature: Definition & Measurement
Core body temperature refers to the temperature of the internal environment of the body. This includes organs such as the heart and liver, and the blood. Learn more about core body temperature, and take a short quiz at the end.
18. Types of Eye Diseases
This lesson gives a description of the eye and examines its anatomy. Also, this lesson will discuss diseases affecting vision as well as the parts of the eye the diseases impact.
