Trivia: What is NOT part of the circulatory system?
Capillaries
Arteries
Veins
Thyroid
The correct answer is Thyroid
So why is this answer correct? : The circulatory system pumps blood from the heart to the rest of the body. Blood first travels from the lungs to the heart, which then sends the oxygenated blood through the rest of the body through many different types of blood vessels, such as arteries and veins. This keeps the body’s muscles, tissues, and organs healthy and functioning.
