About This Chapter
Basic Human Physiology - Chapter Summary
Take a close look at basic human physiology concepts by utilizing this chapter's engaging lessons. Explore various systems of the body, and review problems that can arise in those systems. Topics covered include digestion, the human respiratory system and gastrointestinal health. By the end of this chapter, you will be ready to:
- Define digestion, and describe how this process works
- Discuss common digestive problems and explain how to keep the gastrointestinal tract healthy
- Explain the gas exchange in the human respiratory system
- List common respiratory disturbances
- Share details about the human vascular and excretory systems
- Describe the skeletal, muscular, nervous and endocrine systems
Access these lessons in any order, and view few or as many of the lessons as you need based on your existing knowledge and study goals. You can also use the clickable timeline to skip to specific topics within each video lesson. Gauge your comprehension of the lessons you review by taking short self-assessment quizzes. Ensure you understand the entire chapter using the broader practice exam.
1. What is Digestion? - Definition & Process
This lesson will define the process of digestion. All parts of the gastrointestinal system will be discussed. Examples will be given when possible, and you'll have an opportunity to test your knowledge.
2. Gastrointestinal Health & Digestive Problems
In this lesson, you will learn about digestive health, your gastrointestinal tract and what you can do to keep it healthy. You will also learn about symptoms of common digestive problems.
3. 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.
4. Common Respiratory Disturbances
Have you ever wondered what conditions are related to respiratory function and how they are treated? Learn more about common respiratory disturbances and test your knowledge with a quiz.
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?
6. 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.
7. 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.
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.
9. 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!
