Hemodynamics

The heart plays a crucial role when it comes to blood circulation inthe body. The organ is essential in ensuring that different bodyorgans have access to oxygenated blood while that rich in carbondioxide is eliminated out of the body through expiration. Patientswho develop a disease that affects pumping of the heart exposedifferent body organs to significant risks. The heart pumps blood toorgans in need of oxygen to support various metabolic functions suchas generation of energy. If the heart pump is blocked, it will resultin a shortage of oxygen to the respective organs (Hall, 2015). Theeffect of the same is that normal functioning is hampered. Further,the heart is critical in facilitating the removal of carbon dioxidethrough the lungs. If it is blocked, the effect is an accumulation ofdeoxygenated blood in the circulatory system. The veins transport thedeoxygenated blood from body organs to the heart through the rightarticle that passes on to the right ventricle and pumped to the lungsfor expiration (Hall, 2015). If the heart pump is blocked, suchactivities are hindered.

The aortic pump is significant in circulation since it transportsoxygenated blood from the heart to the brain and the rest of the bodyorgans. A disease affecting the pump results curtails the delivery ofoxygenated to the respective organs. It could result in hypoxia, alife-threatening disease to the particular patient. The calf musclepump drives deoxygenated blood from the lower leg to the heart. Ablockage of the calf muscle pump results in hindrance of the smoothflow of blood to the heart (Hall, 2015). Deoxygenated bloodaccumulates leading to a possible toxicity in circulation. Overall,diseases that affect organs involved in pumping blood to and from theheart expose the patient to significant health risks because of thepossible accumulation of carbon dioxide that is toxic to the cells.

HEMODYNAMICS 1

When a section of the aorta bulges, an aortic aneurysm is formed.While some aneurysms may burst causing death, most of them remainintact. In case the aortic aneurysm bursts, one may experience fastpulse, nausea, vomiting, and dizziness. Most of them are small andoften remain that way, while others may enlarge over time. It ispossible for aneurysms to develop anywhere along the aorta. Forinstance, the thoracic aortic aneurysm forms in the upper part of theaorta. For the thoracic aortic aneurysm, it usually grows slowly andwith subtle symptoms. This makes it hard to detect. Some of thesymptoms of thoracic aortic aneurysm include back pain, shortness ofbreath, coughing, pain in the chest, and hoarseness. Within thethoracic aorta, the aneurysms may develop in different parts such asin the ascending section where the aorta enters the heart. Some ofthe risk factors associated with thoracic aortic aneurysm includegenetic factors, age, high blood pressure, trauma, and tobacco use(Mayo Clinic, 2016).

Aneurysms may also develop in the aortic arch as well as in thedescending part of the thoracic aorta. When they develop on thebottom part of the aorta, the condition is referred to as theabdominal aortic aneurysm. Some of the symptoms that characterizethis condition include back pain, deep and constant pain in theabdomen as well as a pulsating sensation near the navel. Also, it ispossible for the aneurysms to occur between the lower and the upperpart of the aorta, which in this case the condition is referred to asthe thoracoabdominal aneurysm. Some of the risk factors associatedwith abdominal aortic aneurysm include being male, white, smoking,age, high blood pressure, family history, and atherosclerosis (MayoClinic, 2016).
