What is the circulatory system?

Answer 1

The circulatory system is an organ system that moves nutrients, gases, and wastes to and from cells to help fight diseases and help stabilize body temperature and pH to maintain homeostasis. This system may be seen strictly as a blood distribution network, but some consider the circulatory system as composed of the cardiovascular system, which distributes blood, and the lymphatic system, which distributes lymph. While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. The most primitive animal phyla lack circulatory system. The lymphatic system, on the other hand, is an open system.

The main components of the human circulatory system are the heart, the blood, and the blood vessels. The circulatory system includes: the pulmonary circulation, a "loop" through the lungs where blood is oxygenated; and the systemic circulation, a "loop" through the rest of the body to provide oxygenated blood. An average adult contains five to six quarts (roughly 4.7 to 5.7 litres) of blood, which consists of plasma, red blood cells, white blood cells, and platelets. Also, the digestive system works with the circulatory system to provide the nutrients the system needs to keep the heart pumping.

Two types of fluids move through the circulatory system: blood and lymph. The blood, heart, and blood vessels form the cardiovascular system. The lymph, lymph nodes, and lymph vessels form the lymphatic system. The cardiovascular system and the lymphatic system collectively make up the circulatory system.

This system may be seen strictly as a blood distribution network, but some consider the circulatory system as composed of the cardiovascular system, which distributes blood, and the lymphatic system, which distributes lymph.

The circulatory system comprises of the heart, the lungs and the blood vessels. The main objective of the circulatory system is transporting oxygenated (rich saturation of oxygen) blood around the body. The de-oxygenated blood enters through the vena cava and into the right atrium of the heart. It then goes to the right ventricle, directly below the atrium. The next destination is the lung through the pulmonary vein, where diffusion occurs in the alveoli. Carbon Dioxide and wastes are transferred for oxygen. The blood then travels to the left atrium by the pulmonary artery and then to the left ventricle. The blood leaves the heart by the aorta to the other parts of the body.
