List of Circulatory System Parts & their Functions

CIRCULATORY SYSTEM PARTS – Here is a list of the different parts of the body that are part of the cardiovascular system and their functions.

The human body is composed of several systems that have specific and unique functions. One of these is the circulatory system which serves several important functions such as the following:

  • providing oxygen to muscles, tissues, and organs of the body
  • bringing hormones to tissues, muscles, and organs
  • providing nutrients to the organs, muscles, and tissues
  • removing waste from cells and organs

There are three (3) circulatory system parts and each of them performs a specific function. They are the heart, the blood vessels, and the blood.

Circulatory System Parts & their Functions

  • Heart – The heart is the organ that is tasked to pump blood through the veins and arteries. Based on the article, the circulatory system is also called the cardiovascular system with “cardio” referring to the heart and the “vascular” to the blood vessels.
  • Blood Vessels – These are composed of the veins, the arteries, and the capillaries which all play a role in the transport of the blood.
    • Arteries – They are thin, muscular tubes that bring the oxygenated blood away from the heart to each part of the body.
    • Veins – They are blood vessels that bring back the oxygen-depleted blood to the heart.
    • Capillaries – Based on the article, these are the small blood vessels that connect the small arteries or arterioles and the veinsor venules.
  • Blood – It is made up of red and white blood cells, plasma, and platelets and they are necessary for the proper functioning of the tissues throughout the body.

How does the circulatory system works? The heart pumps low-oxygen blood to the lungs and the blood cells pick it up from the lungs. The pulmonary veins bring back the oxygenated blood to the heart and the heart pumps it out throughout the body through the arteries. It drops oxygen, nutrients, and hormones while it travels.
