About This Chapter
ASVAB: The Human Respiratory & Circulatory Systems - Chapter Summary
Across these lessons covering two of the major body systems, you'll see information on the functions of red blood cells, white blood cells and platelets. You will get the proper preparation to also correctly answer ASVAB questions on any of these topics:
- The lymphatic system and its functions
- The structure of hemoglobin
- Different kinds of circulatory systems
- The heart and the human vascular system
- Respiratory system gas exchange
You can use the video tags when rewatching any video lesson to easily pick and choose the points you want to reexamine the most. The chapter's practice quizzes that go with each lesson allow you to get an accurate picture of your comprehension.
Objectives of the ASVAB: The Human Respiratory & Circulatory Systems Chapter
The ASVAB assesses your knowledge across several domains to see how it measures up with qualifications for joining the military. The Human Respiratory & Circulatory Systems chapter prepares you for questions you may see among the General Science subtest items. All of the questions you'll be asked on this subtest make up about 11% of the exam. The quiz questions in this chapter have the same format, being multiple-choice, as all of the ASVAB items.
1. 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.
2. 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.
3. 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.
4. 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?
5. 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.
6. 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.
7. 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)!
8. Functions of Red Blood Cells, White Blood Cells & Platelets
Blood is a connective tissue vital to our body's survival. In this lesson, we will explore the three functions of blood by delving into red blood cells, white blood cells and platelets - the three individual components that make up blood as a whole.
9. Functions of the Lymphatic System
In this lesson, you will learn about the lymphatic system and the vital role it plays in keeping the cardiovascular system working. You'll discover how the lymphatic system (with its lymphatic vessels and capillaries) quietly works in the background to return leaked fluids back to the blood.
