Ch 19: OAE - Integrated Science: Human Body Systems

About This Chapter

The OAE Integrated Science exam features questions on the workings of the human body. This chapter of our OAE study guide helps you review the biology of the human body. It also features questions that will help you practice for your upcoming exam.

OAE Integrated Science: Human Body Systems - Chapter Summary

Prepare to take the OAE Integrated Science exam. This chapter covers all of the many different interacting systems that allow your body to function efficiently on a daily basis. It will explain each system's parts and functions. By the end of the chapter, you will have strengthened your existing knowledge of:

  • The endocrine system
  • The circulatory system
  • The nervous and digestive systems
  • The integumary system
  • The immune system
  • The respiratory system
  • The skeletal system
  • The muscular system

The quizzes that accompany these fun and engaging lessons are modeled on the questions you will encounter during the OAE exam. These questions will help you become comfortable with the pace and timing of the OAE Integrated Science exam. In addition to being animated, the video lessons are narrated by our experienced instructors.

OAE Integrated Science: Human Body Systems Chapter Objectives

The OAE Integrated Science exam has four different domains: earth science, life science, physical science, and the nature of science. This chapter links to the life science domain. The life science domain is 25% of the test. The test itself is 150 multiple-choice questions and it is also computer based. The state of Ohio gives you a three-hour time limit.

The Human Circulatory System: Parts and Functions

1. 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.

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.

Endocrine System Function & Hormone Regulation

3. 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

4. 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.

Digestive System I: The Upper Gastrointestinal Tract

5. 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

6. 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

7. 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.

The Integumentary System: The Dermal Layer

8. 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.

The Integumentary System Accessory Structures: Hair

9. The Integumentary System Accessory Structures: Hair

Your skin does more than just cover your body; it has a number of structures like hair and sweat glands. Learn more about the hair that protects your body in this lesson.

The Integumentary System Accessory Structures: Nails

10. The Integumentary System Accessory Structures: Nails

Did you know that your skin, hair, and nails are all made out of the same protein? Learn more about the structure and function of your nails in this lesson.

The Integumentary System Accessory Structures: Glands

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.

What Is the Immune System? - Our Body's Defense Against Pathogens

12. What Is the Immune System? - Our Body's Defense Against Pathogens

In this lesson, you will be introduced to the immune system. You'll learn about the innate and adaptive immune system, Edward Jenner, haptens and immune tolerance.

Gross Anatomy of the Airway and Lungs: Conducting & Respiratory Zones

13. 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.

Gas Exchange in the Human Respiratory System

14. 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.
