Circulatory System I: Types of Circulatory Systems

1. Circulatory System I: Types of Circulatory Systems

Circulatory systems are essential for survival in animals of all kinds. Explore the different types of circulatory systems, such as open and closed systems, discover how blood flow can be manipulated, and learn how these systems deliver nutrients and remove waste from cells.

Circulatory System II: The Human Vascular System

2. Circulatory System II: The Human Vascular System

The human vascular system carries blood through vessels known as arteries, veins, and capillaries. Explore the human circulatory system, learn how blood moves through the body, and discover the roles of angiogenesis and the lymphatic system.

Circulatory System III: The Heart

3. Circulatory System III: The Heart

The heart lies at the center of a vertebrate's circulatory system. Learn how to define the heart, explore two-, three-, and four-chambered hearts, and discover how the human heart functions.

Blood Vessels: Arteries, Capillaries & More

4. Blood Vessels: Arteries, Capillaries & More

Blood vessels enable blood to flow through the body. Learn about blood vessels, including arteries, arterioles, capillaries, veins, and venules. Understand the functions of blood vessels and explore how blood backflow is prevented.

Regulation of Blood Pressure: Short Term Regulation & Baroreceptors

5. Regulation of Blood Pressure: Short Term Regulation & Baroreceptors

Learn how baroreceptors monitor and regulate the body's blood pressure. Explore the cardiac cycle, diastole, systole, mean arterial pressure, sympathetic and parasympathetic nervous systems, baroreceptor reflex, and orthostatic hypotension.

Functions of the Lymphatic System

6. Functions of the Lymphatic System

A healthy lymphatic system is necessary for a properly functioning cardiovascular system. Learn about the lymphatic system (lymphatic capillaries, lymph nodes, lymph, lymphatic vessels, & lymphatic drainage), the functions of each structure within the lymphatic system, and how edema occurs if the lymphatic system fails to return leaked fluids to the blood.

What Is Blood Plasma? - Function & Components

7. What Is Blood Plasma? - Function & Components

Making up more than half of the composition of blood, blood plasma is primarily made of water and plays an important role in transporting nutrients, electrolytes, and other substances. Learn more about the function and components of blood plasma.

Functions of Red Blood Cells, White Blood Cells & Platelets

8. Functions of Red Blood Cells, White Blood Cells & Platelets

The blood is a connective tissue and it is made up of red blood cells, white blood cells, and platelets and these cells each have a specific function that helps the blood transport minerals, protect the body from germs, and heal wounds. Learn about the functions of red blood cells, white blood cells, and platelets.

Blood Coagulation and Wound Healing

9. Blood Coagulation and Wound Healing

After suffering a wound, the body does everything it can to promote blood clotting and, ultimately, wound healing. The general term hemostasis refers to the stoppage of bleeding, and it just one of the many factors, others being platelets and thromboxane A2, that are essential for proper wound healing. This lesson details the process of blood coagulation, from the clotting factors to the coagulation cascade.

Different Kinds of Cardiovascular Disease: Definitions & Examples

10. Different Kinds of Cardiovascular Disease: Definitions & Examples

With so many working parts, the human heart can be affected by many different kinds of cardiovascular disease. Explore the definition of cardiovascular disease and examples such as valvular heart disease, septal defects, hypertension, deep vein thrombosis, and coronary heart disease.

Cardiovascular Disease Risk Factors & Preventative Strategies

11. Cardiovascular Disease Risk Factors & Preventative Strategies

Cardiovascular disease can be caused by many different risk factors. Explore how drinking, smoking, poor nutrition, diabetes, high blood pressure, and a lack of exercise contribute to this disease, discover the uncontrollable risk factors that play a part, and review the preventative strategies that keep the heart healthy.

Diagnosing and Treating Cardiovascular Disease

12. Diagnosing and Treating Cardiovascular Disease

Understanding the symptoms of cardiovascular disease can help patients recognize when it is time to seek help and clinicians in diagnosing the problem. Learn about the different types of diagnostic techniques, including radiograph or X-ray, CT scan, MRI, angiography, ultrasound, and ECG, and some of the available treatment options, such as heart medications and angioplasty.

Gas Exchange: Diffusion & Partial Pressure Gradients

13. Gas Exchange: Diffusion & Partial Pressure Gradients

Using diffusion and partial pressure, gas exchange, the process of moving oxygen from the air into the blood across a respiratory membrane, is necessary for normal function. Explore the way gas exchange happens, partial pressure gradients, the composition of alveolar air, Dalton's law, and Henry's law.

The Respiratory Surface and Gas Exchange Efficiency

14. The Respiratory Surface and Gas Exchange Efficiency

Gas exchange efficiency occurs due to a thin respiratory surface or membrane that contains many alveoli cells. Learn about the respiratory surface and factors that make gas exchange efficient, as well as how gases are lipid-soluble.

Gross Anatomy of the Airway and Lungs: Conducting & Respiratory Zones

15. Gross Anatomy of the Airway and Lungs: Conducting & Respiratory Zones

The respiratory system ensures the body has sufficient oxygen while removing carbon dioxide. Learn about the gross anatomy of the airway and lungs, including the upper and lower respiratory system, and explore the conducting and respiratory zones by reviewing air movement and gas exchange in the respiratory zones.

Amphibian, Bird & Mammal Respiratory Systems

16. Amphibian, Bird & Mammal Respiratory Systems

The respiratory systems in different animals function differently, each using complex modes of maintaining oxygen levels. Learn how respiration occurs in amphibians, birds, mammals, and humans.

Respiratory Pigments: Animals & Explanation

17. Respiratory Pigments: Animals & Explanation

Respiratory pigments are molecules that increase the carrying capacity of oxygen in blood. Explore hemoglobin, the most common respiratory pigment, and organisms that do not use hemoglobin.

Carbon Dioxide Transport in the Blood

18. Carbon Dioxide Transport in the Blood

Carbon dioxide is transported in the blood in two different forms, bicarbonate and carbaminohemoglobin. In this lesson, dive into carbon dioxide transportation in the blood, in the lungs, and in metabolizing tissues.
