Ch 18: MTEL Biology: The Circulatory, Respiratory, Digestive, Excretory & Musculoskeleton Systems

About This Chapter

We can show you how to recognize important points about the circulatory, respiratory, digestive, excretory and musculoskeleton systems. Our video lessons and self-assessment quizzes provide multiple approaches so you can correctly answer questions on these topics on the MTEL Biology Exam.

MTEL Biology: The Circulatory, Respiratory, Digestive, Excretory and Musculoskeleton Systems - Chapter Summary

Use the lessons in this chapter to learn the essential points about the circulatory, respiratory, digestive, excretory and musculoskeleton systems as you prepare for the MTEL Biology Exam. The videos cover all the topics you need to know, including:

  • Autonomic breathing
  • Stimuli
  • Characteristics of the skeletal and muscular systems
  • Circulatory system
  • Gas exchange and human respiration
  • Upper digestive tract
  • Lower digestive tract
  • The make up of the excretory system

Our knowledgeable instructors go over each topic thoroughly, highlighting the most important concepts and terms. Since you have an array of approaches, learning becomes easier and more enjoyable.

MTEL Biology: The Circulatory, Respiratory, Digestive, Excretory and Musculoskeleton Systems Chapter Objectives

The MTEL Biology Exam is a standardized test that evaluates your mastery of all of biology. Your score is used to determine whether you are qualified to teach the subject. The topics in this Circulatory, Respiratory, Digestive, Excretory and Musculoskeleton Systems chapter are reflected on the Human Anatomy and Physiology section of the test. There will be 17-19 multiple-choice items in this subarea. The self-assessment quizzes available with each lesson will let you evaluate your own mastery of the material, and they'll allow you to experience the types of questions you'll find on the test.

There are 100 multiple-choice items and 2 open-response items on the test. With the multiple-choice items, you will read a passage or question and then select the correct answer from several possibilities. With the open-response items, you will compose an organized, articulate, and logical essay showing your ability to integrate several aspects of biology into a cohesive narrative.

Autonomic Breathing: How Ventilation is Regulated

1. Autonomic Breathing: How Ventilation is Regulated

Did you know that our nervous system controls our breathing? This lesson describes the basic elements of the homeostatic system responsible for balancing oxygen supply with metabolic demand.

Skeletal System and Muscular System

2. 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.

Circulatory System I: Types of Circulatory Systems

3. Circulatory System I: Types of Circulatory Systems

From cnidarians to humans, all animals need a circulatory system to absorb nutrients and get rid of waste. Find out why different kinds of animals have different systems, and see what a closed circulatory system and indoor plumbing have in common.

Circulatory System II: The Human Vascular System

4. Circulatory System II: The Human Vascular System

In this lesson, learn all about the operation of the human vascular system. What are the different types of blood vessels? How does blood flow through the human body? How does the system adapt to your body changing?

Circulatory System III: The Heart

5. Circulatory System III: The Heart

What purpose does the heart serve? And how do different types of hearts function? In this lesson, you'll learn about two, three and four-chambered hearts.

Circulatory System IV: Red Blood Cells

6. Circulatory System IV: Red Blood Cells

Why don't mature red blood cells have nuclei or mitochondria, and how do these guys squeeze through capillaries? While learning about the brief but glorious lives of red blood cells, you'll also see which characteristics help them transport oxygen and carbon dioxide to other cells.

Circulatory System V: Hemoglobin

7. Circulatory System V: Hemoglobin

Did you ever wonder how red blood cells can store enough oxygen to supply the entire human body? Join us in this lesson on hemoglobin to learn why red blood cells are so good at transporting oxygen and carbon dioxide. This lesson will make you see red (as well as blue and purple-maroon)!

Gas Exchange in the Human Respiratory System

8. 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

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.

Digestive System II: The Lower Gastrointestinal Tract

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.

Excretory System

11. 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.
