Students Will Review:
This chapter helps students review the concepts in an introductory unit of a excretory system course. Topics covered include:
- The basics of the excretory system
- Examples of homeostasis
- Function and structure of blood, liver, bile, kidneys, and the intestines
- The components of the integumentary system
1. 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.
2. What Is Homeostasis? - Definition & Examples
Homeostasis can be defined as a property of an organism or system that helps it maintain its parameters within a normal range of values. It is key to life, and failures in homeostasis can lead to diseases like hypertension and diabetes.
3. Blood: Function & Components
You know your heart pumps blood through your blood vessels, but do you know why this is important? Learn why your blood must keep moving, as well as the things that make it up, like plasma, red blood cells, white blood cells and platelets.
4. Liver: Structure & Function
Your liver is a big organ with big jobs. It sits on the right-hand side of your body and helps out with many different tasks that keep you healthy, such as cleaning your blood, storing energy, and making bile and cholesterol.
5. What is Bile? - Definition, Function & Production
Learn about bile and its role in helping you to enjoy some of your favorite things in life. We will look at how it is produced, and then you can take the quiz to test your understanding.
6. 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.
7. Anatomy and Physiology of the Large Intestine
The large intestine is the made up of the cecum, colon, rectum and anal canal. In this lesson, you will learn about the anatomical features and basic functions of these large intestine segments.
8. Rectum, Functions of the Large Intestine & Water Absorption
The large intestine is the final processing area for digested food. In this lesson, you will learn how the large intestine removes water from undigested food and prepares for the elimination of feces through the anus.
9. The Integumentary System: The Epidermal Layer
Do you know what the largest organ in your body is? How about the layers of your skin? Or where skin cancer comes from? Learn the answers to these questions and more in this lesson on the integumentary system.
10. The Integumentary System: The Dermal Layer
Did you know that some people don't feel pain? Or that some always feel as if their skin is on fire? Learn about the causes of these diseases and the anatomy of the skin they affect in this lesson- the dermal layer of the skin.
11. The Integumentary System Accessory Structures: Glands
Ever wonder how pimples appear? Is it simply a blocked pore or maybe a hair follicle? Is bacteria involved? Learn about the glands that cause acne and the glands that help you cool off in this lesson on sebaceous and sweat glands of the integumentary system.
