Ch 7: ScienceSaurus Student Handbook Grades 6-8: Human Biology

About This Chapter

The Human Biology chapter of this ScienceSaurus Student Handbook Grades 6-8 Companion Course helps students learn the essential lessons associated with human biology. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Human Biology textbook chapter.

How It Works:

  • Identify the lessons in the ScienceSaurus Human Biology chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the human biology topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Bones, muscles and joints
  • Upper and lower gastrointestinal tracts
  • Lung function and structure and air exchange
  • Veins, arteries and the heart
  • Nerves and senses
  • Mechanisms of the immune and endocrine systems
  • Male and female reproductive anatomy
  • Process of fertilization; zygote and embryo development

The Skeletal System: Function and Terms

1. The Skeletal System: Function and Terms

You'll learn about the two major divisions of our skeleton, the axial and appendicular skeleton, in this video lesson. In addition, you will find out how bone is formed, thanks to tiny little cells called osteoblasts and osteoclasts, and what the major parts of a long bone are.

Major Muscle Groups of the Human Body

2. Major Muscle Groups of the Human Body

This lesson introduces the major skeletal muscle groups of the human body. It includes illustrations, examples, and descriptions for each major group. A brief quiz and summation of key points are also included.

Joints: Structure and Functions

3. Joints: Structure and Functions

Find out what part of your body is affected when you tear your meniscus, how synovial fluid is made, what the synovial membrane helps to comprise, what a joint is, and why a joint capsule is important.

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.

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

6. 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.

The Human Circulatory System: Parts and Functions

7. 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.

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.

Sensory Organs: Functions & Explanation

9. Sensory Organs: Functions & Explanation

This lesson is about what senses are, and sensory organs that are involved in each one of the senses. Learn how stimuli trigger the senses and how stimuli reaches the brain in each case.

Endocrine System Function & Hormone Regulation

10. 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!

Immune System: Function & Responses

11. Immune System: Function & Responses

The immune system is the body's defense against invaders that could do it harm. This lesson covers the different parts and their functions in protecting the body against infections.

Male Reproductive System: External Anatomy

12. Male Reproductive System: External Anatomy

Learn about the structure and function of the external reproductive structures of the male. This includes study of the scrotal sac, the parts of the penis and the erectile tissues.

Female Reproductive System: Internal Anatomy

13. Female Reproductive System: Internal Anatomy

Ever wonder where a female produces her eggs or how they get from the ovary to the uterus? Find out in this lesson about the internal reproductive anatomy of females.

Fertilization and Zygote Formation: Definition and Processes

14. Fertilization and Zygote Formation: Definition and Processes

Follow the male's sperm and the female's egg on their way to meet each other in this lesson that takes you through the process of fertilization in humans. Learn about the obstacles the sperm must get through before it can fertilize the egg.

Fertilization: Oocyte Activation & Cell Cleavage

15. Fertilization: Oocyte Activation & Cell Cleavage

When is the exact moment of fertilization? Learn the answer in this lesson. We'll look at what happens after the sperm penetrates the outer layers of the oocyte during the process of fertilization.
