Leonardo has often been described as the archetype of the Renaissance Man‚ a man of "unquenchable curiosity" and "feverishly inventive imagination". He is widely considered to be one of the greatest painters

Therefore‚ a very rapid heart will often have

From there it going into the tricuspid valve and goes into the right ventricle which travels to the pulmonic valve and then into the pulmonary artery. After it leaves the pulmonary artery it travels to the pulmonary veins and then becomes oxygenated. Once

Marfan’s Syndrome Marfan syndrome is an inherited connective-tissue disorder transmitted as an autosomal dominant trait. It is distributed worldwide‚ has a high prevalence rate and has pleiotropic manifestations‚ meaning one gene influences multiple traits that do not seem to be related. Mutations of the FBN1 gene on the 15th chromosome (more specifically chromosome 15q21.1) cause Marfan syndrome. The FBN1 gene is coded to make a glycoprotein called fibrillin-1

happens when we start running and needing more blood? The heart still goes at a constant rate but only faster.The normal rate for an adult is 72 beats per minute. Then for the blood from flowing backward‚ there are tricuspid‚ bicuspid‚ aortic‚ and pulmonary valves. The blood goes from the atriums to the ventricles this is never changed or swapped around. Blue blood first enters the heart from either the inferior vena cava or the superior vena cava. The blood doesn’t come randomly from either one

Energy Metabolism Respiration and the Respiratory System- The respiratory system is in charge of getting the oxygen needed for respiration to the blood flow where it is passed by the blood cells around the body to reach each living cell. The lungs have a huge blood supply and a huge surface area so they are very effective at getting oxygen out of the air. They are also in charge of getting rid of the carbon dioxide excess and some of the excess water as water vapour. It is the lungs job to
