About This Chapter
Human Nervous, Circulatory & Respiratory Systems - Chapter Summary
Our instructors have created the lessons in this chapter to provide you with a sufficient overview of the characteristics and roles of the human circulatory, nervous and respiratory systems. By the end of the chapter, you will have examined:
- Parts and functions of the nervous system
- Synapses and transmission
- Nervous system's physiological processes
- Components and purpose of the circulatory system
- Anatomy of the airway and lungs
- Physiology and responsibilities of the respiratory system
- Explanation and equation for respiration
We strive to keep the studying process enjoyable and effective. Our instructors have created these video and text lessons to keep you engaged and adequately illustrate the material being reviewed. For the video lessons, a clickable timeline is available for easy navigation. After each lesson, take a self-assessment quiz to apply what you've learned. After completing all of the lessons, take the chapter exam to see how well you understand the information.
1. 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.
2. Functions of the Nervous System
In this lesson, we'll watch Timmy as he plays in his backyard. Watch what happens when he tries to catch a butterfly, hears a mean dog bark, and scrapes his knee. All of Timmy's reactions are tied to his nervous system. For a full explanation of what goes on in the human nervous system, check out the video!
3. Synapse: Definition & Transmission
Neurons are cells in the nervous system that are necessary to communicate with other bodily cells and systems. This communication is done through connection points known as synapses.
4. Physiological Processes of the Nervous System
Your nervous system is like your body's personal computer, constantly collecting, sorting, and responding to all the information around you. Read on to learn more about how this happens and then test your knowledge with a quiz!
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. 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.
7. Respiratory System: Function & Physiology
The human respiratory system is a crucial facet of a vital, healthy body. In this lesson, we will explore its function and physiology. At the end of the lesson, you can test your knowledge with a brief quiz.
8. What is Respiration? - Definition, Process & Equation
Respiration is a metabolic process common to all living things. Here, you will learn the definition, location, processes, and formula for cellular respiration. At the end, you can test your knowledge with a short quiz.
