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. Blood Vessels: Arteries, Capillaries & More
In this lesson, you will take a trip around the circulatory system and encounter the various blood vessels, including arteries, veins, and capillaries. Come along as we follow the path to every cell of your body.
5. Regulation of Blood Pressure: Short Term Regulation & Baroreceptors
Blood pressure in your blood vessels is closely monitored by baroreceptors; they send messages to the cardio regulatory center of your medulla oblongata to regulate your blood pressure minute-by-minute. In this lesson, you will learn how baroreceptors regulate your short-term blood pressure.
6. 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.
7. What Is Blood Plasma? - Function & Components
Blood plasma is the liquid component of blood that suspends blood cells and many other substances. Find out more about what it's made up of and how it functions with this lesson.
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. Blood Coagulation and Wound Healing
When your blood vessels suffer damage, your body follows a sequence of events to promote blood clotting. In this lesson, you will learn about coagulation cascade and important clotting factors involved in wound healing.
10. Different Kinds of Cardiovascular Disease: Definitions & Examples
So many problems can occur in the cardiovascular system of your body. Some of them mainly involve the heart and others the blood vessels, but one big one involves both at the same time!
11. Cardiovascular Disease Risk Factors & Preventative Strategies
This lesson will describe for you the numerous controllable and uncontrollable risk factors associated with cardiovascular disease as well as important preventative strategies to maximize your health.
12. Diagnosing and Treating Cardiovascular Disease
This lesson will describe the many different ways cardiovascular diseases can be diagnosed and treated. For example, you'll learn the differences between angioplasty and angiography.
13. Gas Exchange: Diffusion & Partial Pressure Gradients
If you've ever experienced shortness of breath on top of a mountain, this lesson is for you. Oxygen and carbon dioxide move into and out of our blood by diffusion. The rate of diffusion is determined by partial pressure gradients across the respiratory membrane in our lungs. Partial pressure is a function of both concentration and atmospheric pressure.
14. The Respiratory Surface and Gas Exchange Efficiency
The respiratory membrane includes millions of alveoli with a surface area as large as a tennis court. This large respiratory surface area, combined with other factors, makes for efficient gas exchange to meet our metabolic needs.
15. 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.
16. Amphibian, Bird & Mammal Respiratory Systems
While something as basic as breathing may sound universal, the fact is that amphibians, birds, and mammals all do it differently. In fact, even humans can't always control their breathing.
17. Respiratory Pigments: Animals & Explanation
A respiratory pigment is a molecule which increases the oxygen carrying capacity of blood. Learn more about the most common respiratory pigment in mammals, hemoglobin, as well as how it works. Also, discover the different types of respiratory pigments used by other organisms.
18. Carbon Dioxide Transport in the Blood
While carbon dioxide is a metabolic waste product, it plays some important physiological roles as well. This lesson describes how carbon dioxide is transported in our blood, how carbon dioxide is converted into a pH buffer, and how carbon dioxide helps with oxygen transport.
