About This Chapter
Human Body Overview - Chapter Summary
These lessons provide information that allows for a thorough human body overview. Learn about the human muscular and skeletal systems. Examine the nervous system of the human body and analyze the lymphatic system and its functions.
Review data on respiratory zones while looking at the gross anatomy of the lungs and airways. See an examination of the lower gastrointestinal tract of the digestive system, and find out about additional lesson subject matter, such as:
- Layers, structure and function of human skin
- Structure and function of the joints of the body
- Parts and functions of the human circulatory system
- Blood flow and the individual parts in looking at the anatomy of the heart
- Upper gastrointestinal tract of the digestive system
- Urinary system's gross anatomy
- Organs, functions and anatomy of the male reproductive system
- Internal anatomy of the female reproductive system
- Female reproductive system's external anatomy
Each lesson in this chapter has a companion quiz for assessing your proficiency in the information covered. The chapter consists of video lessons that include transcripts. The lessons end with a quiz that can actually be taken at any point throughout your studies.
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. 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.
3. Skeletal System and Muscular System
Do you know how many bones are in the human body? Check out this video lesson to uncover the answer, as well as understand the role and importance of the skeletal and muscular systems.
4. 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.
5. The Human Circulatory System: Parts and Functions
In this lesson, you will take a ride on the transportation system of the body called the circulatory system and its two parts: the pulmonary circuit and the systemic circuit. Take a look inside and see how every inch of your body receives the oxygen and nutrients it needs.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. Male Reproductive System: Functions, Organs & Anatomy
Ever wonder what the inside of a male looks like? Find out in this lesson that explores the inner workings of the male reproductive system and the pathway that sperm takes.
13. Female Reproductive System: Internal Anatomy
Ever wonder where a female produces her eggs or how they get from the ovary to the uterus? Find out in this lesson about the internal reproductive anatomy of females.
14. External Anatomy of the Female Reproductive System
We all know that men and women are different. But just how different are they? Learn a little more about the differences between men and women in this lesson on female external reproductive anatomy.
