cardiovascular system. The heart has four main parts: the left ventricle,the right ventricle, the left atrium, and the right atrium. A wall of muscle called the septum separates them. Oxygen-rich blood from the lungs goes to the left atrium by the pulmonary vein. The left atrium then pumps this blood to the left ventricle. The right atrium collects deoxygenated blood from the body and then pumps this deoxygenated blood to the right ventricle. The left vertical…

picking up waste. The elements of the system include; The Heart The heart acts as a muscular pump which is divided into 4 different chambers, the heart's main function is to pump the blood around the body. It pumps deoxygenated blood through the veins, to the lungs for oxygenation which can then be pumped into the various arteries. The transported blood therefore transports oxygen, hormones and nutrients to body tissues. The four chambers in the heart are known as the right atrium, left…

The Cardiovascular System is composed of the heart and the blood vessels. The main function of the cardiovascular system is to pump blood around the body. The cardiovascular System is divided into two parts, the systematic circuit and the pulmonary circuit. The systematic circuit contains oxygenated blood and the pulmonary blood contains deoxygenated blood. In order to prevent oxygenated and deoxygenated blood from mixing there is a structure called an interventricular septum. The septum…

The blood is moved through the pulmonary capillaries and alveoli where it exchanges the CO2 with fresh O2 and then moves out of the lungs via pulmonary veins and moves out of the other chambers of the heart and to the body and once again completes the cycle. It stands to reason that due to the short distance of a trip through the pulmonary system pressure in the lungs would be less than arterial pressure…

right ventricle, the tricuspid valve opens and allows the blood to flow from high to low pressure. The valve then closes to ensure blood only flows in one direction (Tandy 2017). After oxygenation, the blood enters the left atrium via the pulmonary veins and fills it until the pressure inside the atrium is greater than that of the left ventricle. This then causes the mitral valve to open and then close again after the pressure in the ventricle becomes greater. The blood returns to the vena cava…

Total Hip Replacement Hip arthroplasty is using a prosthesis to replace hip joint is one of the most common surgical procedures today (Walker, 2007). A good surgical team will increase the success rate of the total hip replacement. However, proper nursing interventions during pre-operative and post-operative phase of the surgery is very important for the patient. Nurses spend more time with patients compared to the other health care personnel. Therefore, a good nursing care will better…

Deep vein thrombosis condition is one of the world renown vein incompetence that will lead to a fatal condition if mistreatment or underdiagnosed. Generally, DVT is part of the venous thromboembolism that can lead to a fatal condition which can cause sudden death. Currently, the awareness of this condition had been raised purposely on the early diagnosis of this condition. A lot of studies on this topic had been done previously by researchers in their effort to contribute to this condition to be…

The heart muscle itself has its own set of arteries, capillaries, and veins, as does every other organ in the body. They are called the coronary arteries and veins since they encircle the heart. Coronary arteries are supplied with oxygenated blood from the aorta to the myocardium to keep contracting. The left coronary artery feeds most of the left ventricle, the septum and much of the conduction system. The right coronary artery feeds the right side of the heart, including the sinoatrial (SA)…

story questions then temperature, blood pressure, pulse and hemoglobin are checked to ensure donor’s blood is safe to use.), donating (where the donor is asked to sit on a chair. His or her blood is cleaned with alcohol and a needle is inserted into a vein in his or her arm. The needle is removed after fifteen minutes when nearly a pint of blood of blood has been collected.) and refreshment (where the donor spends a few minutes enjoying refreshments to replace the fluids that he or she lost…

Vascular smooth muscle cells (VSMC) and extracellular matrix (ECM): Blood vessels, include arteries that transport blood from the heart to the systemic circulation, and veins that transport blood back again into the heart. A remarkable change in blood vessel structure and function happened, with the emergence of a high-pressure, pulsatile circulatory system in vertebrates. Blood vessels then evolved from simple tubes for channeling blood or other body fluids from a low-pressure heart. According…
