The Blood Vessels - Chapter Summary and Learning Objectives

Human beings have a highly sophisticated system of blood vessels that carry blood to and from the heart, as well as all around the body. In this series of video lessons, you'll learn more about specific sub-sets of blood vessels that carry out particular functions. These lessons are taught by an experienced life science instructor, and at the end of the chapter, you should be able to:

  • Describe blood vessels in general, their structure and function
  • Identify blood vessels between the heart and lungs
  • Identify blood vessels that carry blood leaving the heart
  • Identify blood vessels that carry blood to the heart
  • Identify blood vessels related to the thoracic and abdominal aorta

Video Objective
Blood Vessels: Arteries, Capillaries, and More Define the major types of blood vessels; describe their components and each component's function.
Major Blood Vessels Between the Heart and Lungs: Pulmonary Trunk, Arteries, and Veins Identify and describe the function of the major blood vessels that run between the heart and lungs.
Major Blood Vessels That Carry Blood Away From the Heart Identify and describe the function of the major blood vessels that run from the heart, including the ascending aorta, coronary arteries, the aortic arch, and baroreceptors.
Major Blood Vessels: Descending Aorta - Thoracic and Abdominal Aorta Identify and describe the function of the major blood vessels of the descending aorta.
Major Blood Vessels Leading to the Heart: Superior Vena Cava, Inferior Vena Cava, and Coronary Sinus Identify and describe the function of the major blood vessels carrying blood to the heart.

Major Blood Vessels Between the Heart and Lungs: Pulmonary Trunk, Arteries & Veins

2. Major Blood Vessels Between the Heart and Lungs: Pulmonary Trunk, Arteries & Veins

In this lesson you will learn about the main blood vessels that travel between the heart and lungs. You will also discover that these arteries and veins follow a somewhat unusual pattern.

Major Blood Vessels That Carry Blood Away From the Heart

3. Major Blood Vessels That Carry Blood Away From the Heart

Do you know which arteries are typically blocked during a heart attack? In this lesson, you will learn about the major blood vessels that feed the heart, brain and upper body. Then, find out what causes the pain known as angina.

Major Blood Vessels: Descending Aorta - Thoracic and Abdominal Aorta

4. Major Blood Vessels: Descending Aorta - Thoracic and Abdominal Aorta

The aorta is the largest artery of your body, and it is a strong and sturdy vessel. In this lesson, you will learn about its downward path through the chest and abdomen and discover the organs and structures supplied by its branches.

Major Blood Vessels Leading to the Heart: Superior Vena Cava, Inferior Vena Cava & Coronary Sinus

5. Major Blood Vessels Leading to the Heart: Superior Vena Cava, Inferior Vena Cava & Coronary Sinus

In this lesson, you will learn about the main blood vessel that returns blood to the heart called the Venae Cavae. You'll also learn about its two sections: the Superior and Inferior Vena Cava. You will then discover the special drainage system for the heart called the Coronary Sinus.
