systemic route blood is moved through the body providing it with oxygen and nutrients while blood with no oxygen is sent back to the heart. When the pulmonary enters the left to part of the heart called the atrium oxygen goes through the pulmonary veins. After it leaves the left atrium and goes to the ventricle through a valve that is called the martial

12-7-15 Anatomy Cardiovascular System The Cardiovasuclar system is one of the most important systems in your body and it is also one of the largest systems in your body. This system consists of the heart‚ and a system of vessels called arteries‚ veins and capillaries. They are responsible for transporting‚ nutrients hormones‚ oxygen and waste throughout the body. All of these play an important part in this system and the system would fall apart if one wasn’t there. This system is is powered by

through the Superior Vena Cava which is the large vein at the top of the heart‚ and the Inferior Vena Cava‚ which is the large vein at the bottom of the heart. Blood flows into the right atrium‚ passes through the tricuspid valve‚ and makes its way into the right ventricle. It then moves through the pulmonic valve‚ into the pulmonary artery to the lungs.” After picking up oxygen in the lungs‚ the blood moves out of the lungs into the pulmonary vein‚ into the left atrium‚ through the mitral valve‚

Low Molecular Weight Heparin Paper Low molecular weight heparin is typically used for patients who need to be treated for deep vein thrombosis. Deep vein thrombosis (DVT) is a blood clot (thrombus) in a deep vein usually in the legs. These clots are dangerous because they can break loose‚ travel through the bloodstream to the lungs‚ and block blood flow in the lungs (pulmonary embolism). There are many reasons why clots form in a patient. Mainly

developing maternal blood supplies the oxygen‚ blood‚ and nutrients to the fetus and takes away the waste. The exchange of maternal blood and fetal blood to the fetus happens through the placental membrane and the umbilical cord vessels. The umbilical vein goes into the body through the umbilical ring‚ and half of the blood running though it goes to the liver and the rest goes to the ductus venous. It joins with the inferior vena cava. Blood goes to the fetal right atrium from the inferior vena cava

atherosclerosis‚ and arteriovenous malformation. Some that are less common‚ but do occur would include drugs‚ infection‚ and trauma. Dissecting aneurysms occur when blood enters a vessel wall through a rupture in the intima‚ which is the inner lining of vein or artery. The damage in dissecting aneurysms varies greatly depending on the damage it has already caused. These are the weakest aneurysms‚ because they don’t leave the premises of the parent vessel. There are cases were dissecting aneurysms cause

more oxygen. The pump on the left hand side receives oxygenated blood and then pumps it into the arteries to deliver its oxygen around the body. The deoxygenated blood enters the top right chamber of the heart‚ named the right atrium‚ through two veins. Blood from the upper portion of the body‚ like the head and arms‚ flows in through the superior vena cava. Blood from the lower body‚ which are the legs‚ comes in by the inferior vena cava. The blood that is in need of oxygen is forced to leave the
