About This Chapter
Anatomy and Physiology - Chapter Summary
In this chapter, professional instructors will lead you through explanations of human body systems' anatomical functions and structures. You'll be introduced to the relevant terminology associated with this topic and will learn about the different categories and characteristics of amino acids, multicellular organisms and how skin functions. You'll study the epithelial tissues that line organs and blood vessels, the reasons and methods for dividing up the human body and the roles that the female and male reproductive systems play. If you're curious about how the human circulatory system functions or you want a refresher on how the nervous system works, you'll find that info in this chapter. When you finish this chapter, you should be familiar with:
- The respiratory system
- Epithelial tissue
- Causes of major heart conditions
- How wounds heal
- The location of endocrine glands
- The sensory system
- How bone is formed
- The anatomy of the brain
This chapter offers short but engaging lessons on anatomy and physiology. Each lesson is followed by a self-assessment quiz. Use the quiz to test your knowledge of the subject matter and determine what topics you need to review. Go back and look at the main points of each video using the video tags. Follow along with the professional instructors that teach these lessons by utilizing the lesson transcripts. In many lessons, you can also click on links that lead to in-depth text lessons providing details on related terms and concepts.
1. Proteins III: Structure and Characteristics of the 20 Amino Acids
How do amino acids form the intricate polypeptide chains found in proteins? It's a matter of chemistry. Join glycine, a special amino acid, as she sizes up the other amino acids.
2. Multicellular Organisms, Tissues and Epithelium
In this lesson on multicellular organisms, you'll take a look at what it actually means to be multicellular and how cells are organized into tissues, organs, and organ systems. This lesson also covers one of the four main tissue types: epithelial tissue.
3. 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.
4. Planes of the Human Body: Definition, Anatomy & Diagram
Learn about the different ways in which your body can be divided or cut up for theoretical and practical purposes as we explore the sagittal plane, transverse plane and coronal plane.
5. 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.
6. 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.
7. Types of Heart Conditions and Diseases
Your heart muscle receives a rich blood supply from the coronary arteries. If the coronary arteries become blocked, it can result in coronary heart disease, angina, heart attack or congestive heart failure. Learn how these conditions get started.
8. Blood Coagulation and Wound Healing
When your blood vessels suffer damage, your body follows a sequence of events to promote blood clotting. In this lesson, you will learn about coagulation cascade and important clotting factors involved in wound healing.
9. Hormones: Definition, Function & Intro to the Endocrine System
This lesson introduces the endocrine system and provides a brief overview of each endocrine gland. It also provides the definition of hormones and describes their general function inside the body.
10. Gross Anatomy of the Human Brain: Major Anatomical Structures and Terminology
In this video, you'll find out how and why we divide our brain into major sections. It's not just random names and games. You'll learn about where these divisions occur, what we call them, and what they separate.
11. 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!
12. 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.
13. 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.
14. 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.
15. Oogenesis: How the Female Reproductive System Produces Eggs
Did you know that a human female already has all of the oocytes that she will make in her entire life before she is even born? In this lesson, you'll learn how the human body produces an ovum through the process of oogenesis. You'll also learn how polar bodies help to ensure that female gametes are of high quality even though they are not produced in high quantities.
