  1. Circulatory System: Facts, Function & Diseases The circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, oxygen and other gases, and hormones to and from cells. Without the circulatory system, the body would not be able to fight disease or maintain a stable internal environment – such as proper temperature and pH – known as homeostasis. Description of the circulatory system While many view the circulatory system as simply a highway for blood – it is also known as the cardiovascular system – it is made up of three independent system that work together: the heart (cardiovascular), lungs (pulmonary) and arteries, veins, coronary and portal vessels (systemic).

  2. The heart, blood, and blood vessels make up the cardiovascular component of the circulatory system. In includes the pulmonary circulation, a “loop’’ through the lungs where blood is oxygenated. It also incorporates the systemic circulation, which runs through the rest of the body to provide oxygenated blood.

  3. [Top 10 Amazing Facts About Your Heart] The pulmonary circulatory system sends oxygen-depleted blood away from the heart through the pulmonary artery to the lungs and returns oxygenated blood to the heart through the pulmonary vein.

  4. If all the blood vessels in your body were laid end to end, they would extend for 60,000 miles ( more than 96,500 kilometers). That’s enough to circle the Earth more than twice. Capillaries are so small that red blood cells have to travel through them in a single file line. You can feel your pulse on any part of your body where an artery is compressed by a bone.
