1. Human Skin: Layers, Function & Structure
This lesson will cover the three main layers of your skin, which includes the epidermis, dermis, and subcutis. In addition, we'll learn about other skin cells and tissue, such as adipose tissue, keratinocytes, melanocytes, and Merkel's cells.
2. Types of Connective Tissue
In this lesson, you'll learn about the various types of connective tissues in the body. These tissues include bone, fat, cartilage and blood. They form the framework of the body, support organs and much, much more!
3. The Skeletal System: Function and Terms
You'll learn about the two major divisions of our skeleton, the axial and appendicular skeleton, in this video lesson. In addition, you will find out how bone is formed, thanks to tiny little cells called osteoblasts and osteoclasts, and what the major parts of a long bone are.
4. Joints: Structure and Functions
Find out what part of your body is affected when you tear your meniscus, how synovial fluid is made, what the synovial membrane helps to comprise, what a joint is, and why a joint capsule is important.
5. What Is the Muscular System? - Function & How Muscles Work in Groups
Ever feel overwhelmed when you look at all those muscles in your textbooks? Well, if you do, then maybe learning a little about their anatomy and organization and how they work together will help you sort through it all. In this lesson, learn about the muscle itself and how it works with others to help the muscular system function.
6. Nervous System Overview: Central & Peripheral
What happens in your nervous system when you react to stimuli? Did you know that the brain is sometimes uninvolved with reflexes? Find out the answer to these questions, and more, in this lesson on the human nervous system.
7. Anatomy of the Heart: Blood Flow and Parts
In this lesson, you will take a look inside the heart and identify the chambers and one-way valves that make up this vital organ. You will also follow along as we trace the flow of blood through the heart chambers.
8. The Cardiac Cycle: Phases, Explanation & Terms
In this lesson, you will learn what happens during each heartbeat, or cardiac cycle. You will also learn that the heartbeat involves periods of relaxation and contraction, known as diastole and systole, respectively.
9. Functions of the Lymphatic System
In this lesson, you will learn about the lymphatic system and the vital role it plays in keeping the cardiovascular system working. You'll discover how the lymphatic system (with its lymphatic vessels and capillaries) quietly works in the background to return leaked fluids back to the blood.
10. Gross Anatomy of the Airway and Lungs: Conducting & Respiratory Zones
The respiratory system includes the lungs as well as other organs that help to get oxygen into the blood and carbon dioxide out of the blood. The conducting zone of the respiratory system carries oxygen into the lungs and carbon dioxide out of the lungs. The respiratory zone is where oxygen and carbon dioxide move into and out of the blood.
11. Digestive System I: The Upper Gastrointestinal Tract
Did you know that there are digestive enzymes in your saliva? It's true. As soon as you put a piece of food in your mouth, the digestive process begins. Join us with this first of two lessons about the human digestive system, where we'll follow food through the upper gastrointestinal tract from the mouth through the stomach.
12. Digestive System II: The Lower Gastrointestinal Tract
The lower gastrointestinal tract is the part of the digestive system that is responsible for the last part of food digestion and the expulsion of waste from the body. In this lesson, we'll look at each part of the system and what functions each serves in the process of digestion.
13. Excretory System
Each year in the U.S., close to 400,000 people with kidney failure undergo dialysis treatment in order to remove waste, remove excess fluid and restore electrolyte balance. Kidneys, the workhorses of the excretory system, perform these same functions more effectively than any machine. In this lesson, we'll talk about how the excretory system removes toxic substances from the body.
14. Gross Anatomy of the Urinary System
Our body must detoxify and cleanse itself to thrive. That is why we depend so heavily on our liver and urinary system. In this lesson, we'll explore how toxins are filtered by our organs and how urine is formed and expelled with the nephron, bladder, ureters, and urethra.
15. Kidneys: Structure & Function
Your kidneys don't get a lot of attention, but they are important to your health. Learn about your kidneys and the jobs they do, like filtering wastes out of your blood, balancing fluids, adjusting your blood pressure and helping to make blood cells.
