About This Chapter
Who's It For?
Anyone who needs help learning or mastering circulatory and respiratory systems material will benefit from the lessons in this chapter. There is no faster or easier way to learn about the circulatory and respiratory systems. Among those who would benefit are:
- Students who have fallen behind in understanding the structure of the circulatory and respiratory systems
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning human physiology (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about the circulatory and respiratory systems
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How it works:
- Find videos in our course that cover what you need to learn or review.
- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing The Circulatory and Respiratory Systems chapter exam.
Why it works:
- Study Efficiently: Skip what you know, review what you don't.
- Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
- Be Ready on Test Day: Use the circulatory and respiratory systems exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any circulatory and respiratory systems question. They're here to help!
- Study With Flexibility: Watch videos on any web-ready device.
Students Will Review
This chapter helps students review the concepts in a circulatory and respiratory systems unit of a standard biology course. Topics covered include:
- The types of circulatory systems and how they function
- The vascular system in humans
- The structure of the human heart and how it functions
- Red blood cells and hemoglobin
- Anatomy of the respiratory system and the gas exchange process
1. Circulatory System I: Types of Circulatory Systems
From cnidarians to humans, all animals need a circulatory system to absorb nutrients and get rid of waste. Find out why different kinds of animals have different systems, and see what a closed circulatory system and indoor plumbing have in common.
2. 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?
3. Circulatory System III: The Heart
What purpose does the heart serve? And how do different types of hearts function? In this lesson, you'll learn about two, three and four-chambered hearts.
4. Circulatory System IV: Red Blood Cells
Why don't mature red blood cells have nuclei or mitochondria, and how do these guys squeeze through capillaries? While learning about the brief but glorious lives of red blood cells, you'll also see which characteristics help them transport oxygen and carbon dioxide to other cells.
5. Circulatory System V: Hemoglobin
Did you ever wonder how red blood cells can store enough oxygen to supply the entire human body? Join us in this lesson on hemoglobin to learn why red blood cells are so good at transporting oxygen and carbon dioxide. This lesson will make you see red (as well as blue and purple-maroon)!
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. 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.
8. Bundle of His: Definition, Function & Anatomy
The average person's heart beats 60-100 times per minute, pumping out an impressive 5 liters of blood. Sound simple? Well, the heart's function is anything but simple. The following lesson provides an overview of the intrinsic conduction of the heart with a special focus on the Bundle of His.
