How Blood Travels Throughout the Body

1. How Blood Travels Throughout the Body

This lesson is going to cover the different blood vessels that carry blood throughout the body. The route and changes in blood pressure will also be discussed. A short quiz will follow.

What is a Lymph? - Definition & Anatomy

2. What is a Lymph? - Definition & Anatomy

In this lesson, you will learn about lymph, a fluid that forms in your body's tissues. You will explore how lymph is produced, how it moves through your body, and why it is important to your overall health. A post-lesson quiz will test your knowledge.

Double Circulation: Definition & Advantage

3. Double Circulation: Definition & Advantage

Humans and many other organisms use a double circulatory system. This means that we have two separate circuits for blood in our body. Learn how these circuits differ and the function of each one.

Regulation of Heart Rate and Stroke Volume

4. Regulation of Heart Rate and Stroke Volume

The amount of blood being pumped through your body changes constantly due to the demands of daily life. In this lesson, you will learn how your body adjusts the heart rate and stroke volume to increase or decrease blood flow.

What Is Hypertension (HTN)? - Definition, Symptoms & Causes

5. What Is Hypertension (HTN)? - Definition, Symptoms & Causes

It is likely that high blood pressure, or hypertension, has affected you or someone close to you. In this lesson, we will define hypertension and get a better understanding of its causes and symptoms.

Coronary Artery Disease Terminology

6. Coronary Artery Disease Terminology

Coronary Artery disease is the primary cause of heart attacks and strokes, which affect millions of people each year. In this lesson, learn about how coronary artery disease develops over time and what might happen after you have a heart attack.
