Verified step by step guidance

1. Step 1: Understand the function of blood vessels in the cardiovascular system. Blood vessels are responsible for transporting blood throughout the body, delivering oxygen and nutrients, and removing waste products.
2. Step 2: Identify the three main types of blood vessels based on their structure and function: arteries, veins, and capillaries.
3. Step 3: Recall that arteries carry blood away from the heart, veins carry blood toward the heart, and capillaries are small vessels where exchange of gases and nutrients occurs between blood and tissues.
4. Step 4: Recognize that lymph nodes and lymphatic vessels are part of the lymphatic system, not the cardiovascular system, so they are not classified as main blood vessels.
5. Step 5: Conclude that the correct set listing the three main types of blood vessels in the human cardiovascular system is: arteries, veins, and capillaries.
