Ch 5: Human Body Organs & Systems

About This Chapter

Watch our video lessons and read texts about human anatomy at the organ and organ system levels. Whether you're learning or just brushing up for review, the lessons will take you through all the essential concepts in a simple and succinct way.

Human Body Organs & Systems - Chapter Summary

In this chapter's lessons our knowledgeable instructors will review basic things like what constitutes an organ system and the essential components of each major organ system in the human body. Whether you're preparing for an important exam necessary for your chosen career, or you just need some extra help to get through a human anatomy class, you can benefit from our study guide.

Our expert instructors have created the videos to be brief but thorough. They also strive to make them enjoyable for you because they love their job! So get ready for a trip through the human body with our subject matter experts as your guide. Upon completion of this chapter, you should be able to demonstrate understanding of:

  • Parts and functions of the human circulatory system
  • How and where gas exchange occurs in the human respiratory system
  • The digestive processes and key players of the upper and lower gastrointestinal system
  • How waste is formed and excreted by the human body
  • The function and regulation of the endocrine and nervous systems
  • The fundamental components of the lymphatic system
  • How the muscular and skeletal systems enable mobility in humans

We believe in simplifying the learning process as much as possible. We accomplish this by providing short video lessons as well as self-assessment quizzes for you to identify any weak areas you need to review more. You can either re-watch videos or review the lesson transcript included with each. The videos are easy to navigate and you can skip past any subjects you don't want to review, rather than having to watch entire videos. So let's get started!

What Is an Organ System? - Definition & Pictures

1. What Is an Organ System? - Definition & Pictures

In this lesson, you will learn what an organ system is, and you will review each organ system in the human body. This will aid in your study of human anatomy and physiology. At the end of the lesson, a quiz will test your knowledge.

The Human Circulatory System: Parts and Functions

2. 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.

Gas Exchange in the Human Respiratory System

3. Gas Exchange in the Human Respiratory System

Did you know that the average human lung has a respiratory surface area that is roughly the same size as half of a tennis court? Believe it or not, that's how much surface area an active, healthy human needs to ensure that the body gets plenty of oxygen.

Digestive System I: The Upper Gastrointestinal Tract

4. 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.

Digestive System II: The Lower Gastrointestinal Tract

5. 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.

Excretory System

6. 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.

Endocrine System Function & Hormone Regulation

7. Endocrine System Function & Hormone Regulation

Our hormones play a big part in how we feel and behave throughout the day. Hormones also affect important bodily functions. What other functions do our hormones regulate? Find out in this lesson on the endocrine system!

Nervous System Overview: Central & Peripheral

8. 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.

The Lymphatic System: Definition and Fundamental Components

9. The Lymphatic System: Definition and Fundamental Components

This lesson will cover something known as the lymphatic system. You'll learn about bone marrow, lymph, the thymus, lymph nodes, spleen, and much more as we explore this critical component of your immune system.

Skeletal System and Muscular System

10. 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.
