Ch 21: AP Biology - The Circulatory, Respiratory, Digestive, Excretory, and Musculoskeletal Systems: Tutoring Solution

About This Chapter

The Circulatory, Respiratory, Digestive, Excretory and Musculoskeletal Systems chapter of this AP Biology Tutoring Solution is a flexible and affordable path to learning about these systems. These simple and fun video lessons are each about five minutes long and they teach all of the information involving the circulatory, respiratory, digestive, excretory and musculoskeletal systems required in a typical AP biology course.

How it works:

  • Begin your assignment or other AP biology work.
  • Identify the circulatory, respiratory, digestive, excretory and musculoskeletal systems concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our AP biology tutoring solution will benefit any student who is trying to learn about the circulatory, respiratory, digestive, excretory and musculoskeletal systems and earn better grades. This resource can help students including those who:

  • Struggle with understanding multicellular organisms, tissue, epithelium or any other circulatory, respiratory, digestive, excretory and musculoskeletal systems topic
  • Have limited time for studying
  • Want a cost effective way to supplement their science learning
  • Prefer learning science visually
  • Find themselves failing or close to failing their circulatory, respiratory, digestive, excretory and musculoskeletal systems unit
  • Cope with ADD or ADHD
  • Want to get ahead in AP biology
  • Don't have access to their science teacher outside of class

Why it works:

  • Engaging Tutors: We make learning about circulatory, respiratory, digestive, excretory, and musculoskeletal systems simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live biology tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn circulatory, respiratory, digestive, excretory, and musculoskeletal systems on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning Objectives

  • Become familiar with the different types of connective tissue.
  • Take a look at the different types of circulatory systems.
  • Understand the role of hemoglobin and red blood cells.
  • Explain how gas is exchanged in the human respiratory system.
  • Describe the different functions of the upper and lower gastrointestinal tracts.
  • Learn the functions of the excretory system.

Multicellular Organisms, Tissues and Epithelium

1. 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.

Types of Connective Tissue

2. Types of Connective Tissue

In this lesson, you'll learn about the various types of connective tissues in the body. These tissues include bone, fat, cartilage and blood. They form the framework of the body, support organs and much, much more!

Skeletal System and Muscular System

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.

Circulatory System I: Types of Circulatory Systems

4. 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

5. 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

6. 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

7. 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

8. 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

9. 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

10. 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

11. 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

12. 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.

Gastrovascular Cavity: Definition & Explanation

13. Gastrovascular Cavity: Definition & Explanation

Primitive animals have body plans that are very different from ours. Animals such as jellyfish, corals and flatworms have a much simpler way to handle the digestion of food, as well as the circulation of nutrients around the body. Learn about the structure and function of the gastrovascular cavity in these organisms.

Ingestion: Definition & Process

14. Ingestion: Definition & Process

In this lesson, we're going to explore what ingestion means, as well as the various forms that organisms use to consume substances into their bodies or cells. When you are through, test your knowledge with a quiz.

Mastication: Definition & Muscles

15. Mastication: Definition & Muscles

Mastication is the medical term for chewing. Every time you eat, you undergo the mastication process. Learn more about what chewing actually does to your food and which muscles are involved in the process - it's the first step in digestion, so why wouldn't you want to know more about it!

Animals with Open Circulatory Systems

16. Animals with Open Circulatory Systems

What do insects, lobsters, and clams have in common? The answer is that these animals possess an open circulatory system. This lesson describes open circulatory systems and the animal groups that possess them.
