10 Interesting Facts about Cardiovascular System

One of these following facts about Cardiovascular System should give you much information about cardiovascular. Cardiovascular system or can be called circulatory system is an organ system that permits blood to circulate and transport nutrients. It is divided into two, cardiovascular system that distributes blood and the lymphatic system that circulates lymph. There are two separate systems. The lymph takes a lot longer than that a blood. Blood is a fluid consisting plasma, red blood cells, white blood cells, and platelets. Below are some facts about Cardiovascular System.

Facts about Cardiovascular System 1: Structure

The Cardiovascular sytem of humans are closed. It means that the blood never leaves the network of blood vesselslyers and enter interstitial fluid. It carries oxygen and nutrients to the largest cells. The other component of of circulatory system is not  closed.

Facts about Cardiovascular System 2: Human Cardiovascular Componen

The component of human Cardiovascular system are heart, blood, and blood vessels. It includes pulmonary circulation, a loop through the lungs where blood is oxygenated. A loop provides oxygenated loop. Blood consists of plasma, red blood cells, white blood cells, and platelets.

Facts about Cardiovascular System 3: Circulation System

Circulation system is the portion which cardiovascular transports oxygenated blood away from the heart through the aorta. The circulation brings blood to all parts of body except lungs. This system is distance-wise much longer than pulmonary circulation.

Facts about Cardiovascular System 4: Coronary Circulation

Coronary circulatory system serves blood supply to the myocardium. It arises from the aorta by two coronary arteries, the left and the right. After nourishing the myocardium blood returns through the coronary veins into the coronary sinus.

Facts about Cardiovascular System 5: Pulmonary Circulation

Pulmonary circulatory system is the part of cardiovascular system. Her oxygen-depleted blood is pumped away from the heart. Through the pulmonary artery the blood is pumped into the lungs and returned, oxygenated to the heart via pulmonary vein.

Facts about Cardiovascular System 6: Oxygen Transportation

About 98 % of the oxygen of healthy human brething air pressure is chemically combined with hemoglobin molecules. The hemoglobin is the primary transporter oxygen in mammals and many other species.

Facts about Cardiovascular System 7: Vertebrates Cardiovascular System

Vertebrates Cardiovascular system of all vertebrates are closed just as in humans. The system of fish, amphibians, reptiles, and birds  commit the evolution in circulatory system. Its stages are heart-vessels of systemic circulation-vessels of the pulmonary circulation.

Facts about Cardiovascular System 8: Open Circulatory System

Open circulatory system is a system which hemocoel bathes the organs directly with oxygen and nutrients. There is no distinction between blood and interstitial fluid. It combines fluid called hemolymph.

Facts about Cardiovascular System 9: Absence of Circulatory System

Some animals commit the absence in circulatory systems. Their body cavity has no lining. Muscular pharynx leads to an extensively branched digestive ystem that facilitates direct diffusion of nutrients to all cells.

Facts about Cardiovascular System 10: Discovery

In the 16th century, Ebers Papyrus, an ancient Egyptian medical papyrus found a new perceptions in circulatory system. It acknowledges the connection of the heart to the arteries. He thought that air came in through the mouth and into the lungs and heart. Then, the air brought to every member through the arteries. This concept is not fully correct, it represents one of the earliest accounts of scientific thought.

Those are the facts about cardiovascular system. There are many interesting facts. Hope those points give much informations that give benefit for all people.
