TExES Science 7-12: Human Organ Systems - Chapter Summary
Get ready for success on the TExES Science 7-12 test by reviewing what you know about human organ systems. Our expert instructors crafted these text and video lessons to cover the systems that involve:
- Connective tissue and epithelium
- Bones and muscles
- The features of animal body plans
- Circulation, gas exchange and respiration
- Digestion and excretion
- Parts of the nervous system
- Neurons and homeostasis
- The brain
- Immune responses
- Viruses and vaccines
Lessons are available in video and transcript form, allowing you to pick how you want to review the physical processes associated with each organ system. You can complete the quizzes at the end of each lesson to further examine the anatomy and physiology of these systems.
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.
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!
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.
4. Animal Body Plans: Classifications and Features
The Animal Kingdom is diverse and complex. How do we make sense of it all? Scientists use body plans to classify and organize the animals of Earth, making it much easier to differentiate between them.
5. 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.
6. 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.
7. The Digestive System: Functions & Physiological Processes
In this lesson, we explore the functions and processes of the digestive system, where the food we eat is broken down and turned into the energy we use to do virtually everything else. A short quiz follows.
8. 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.
9. The Human Nervous System: Parts & Functions
Your nervous system allows you to experience the world around you and react to it. It's a complex system that's split into two main parts, the central nervous system and the peripheral nervous system. Read on to learn the parts and functions of the system.
10. The Structure and Function of Neurons
In this video lesson, you'll learn about neurons, which are specialized cells in the nervous system. Check out how far neurons can send signals throughout the body and how depolarization is much like 'the wave' at a football game.
11. Homeostasis and Temperature Regulation in Humans
Do you wonder how your body is able to maintain a consistent temperature? Have you ever questioned why you get goosebumps when you're cold? This lesson will introduce you to homeostasis and answer your questions about body temperature regulation and reactions, like goosebumps.
12. The Human Brain: Structure & Functions
The human brain can be divided into three sections. In this lesson, we'll examine the hindbrain, midbrain, and forebrain, as well as the major structures in each. We'll also cover the functions of major brain structures.
13. The Human Immune System: Inflammation & Antibodies
A body as efficient as ours deserves an equally efficient immune system to protect it. Luckily for us, the efficiency of the immune system is its greatest strength, as this lesson demonstrates.
14. Pathogens, Viruses, Antibiotics & Vaccines
Pathogens, including viruses, are the cause of much of the sickness in the world today. Luckily, in the last few decades we have developed a range of tools to use against them, especially antibiotics and vaccines.
