Major Organs Of The Circulatory System

2) The primary functions of the circulatory system is to supply blood to all of its tissues, transport nutrients to its cells, and transport gas. The circulatory system also makes sure that thermoregulation, keeping internal environment within temperature range, takes place to maintain homeostasis. Lastly, the circulatory system keeps the body from harm by fixing any damages done to the body and providing protection against unwanted organisms.

3) The circulatory system itself has three major organs included, but within this system, there is an open circulatory system and a closed circulatory system, also called the cardiovascular system, that also contain their own major organs. The cardiovascular system includes the single circulation system and the double circulation system. In the circulatory system, the major organs include a circulatory fluid, a vasculature or system of vessels, and a pump such as a heart. In the open circulatory system, the major organs include hemolymph (circulatory fluid), the heart, and an incomplete vasculature. In the cardiovascular system, the major organs include ventricle, atrium, artery, capillaries, arterioles, capillary bed, venules, and the veins.
Since the muscle tissue is responsible for movement, the heart can be thought of as a muscle because if the hearts stops working, then there is no movement and the body of the organism stops working and if the heart is working, then there is movement and the body of the organism is working. Another major organ of the circulatory system, the arteries, is made up of the connective tissue. The connective tissue is responsible for holding organs together and the arteries do exactly that by supporting other
