Pericardium
The function of the heart is to pump blood around the body. It consists of 4 chambers, two upper called atria and two lower called ventricles. the right side of the heart receives deoxygenated blood from around the body and pumps this to the lungs via the pulmonary arteries. After oxygenation within the lungs the blood is then returned to the heart via the pulmonary veins into the left atrium.
The oxygenated blood is then pumped from the left side of the heart to the rest of the body.
Within the heart itself there are several layers. The pericardium is a covering of fibrous tissue covering the large blood vessels which enter and leave the heart. The epicardium is just within the pericardium and secrets a lubricating fluid, or serum which prevents

    The blood flows through our heart in a series of different steps and factors. Oxygen flows into the heart through the right atrium where at this time the tricuspid valve is closed, allowing the blood to fill the right atrium. Next, the muscle walls of the right atrium contract and push the blood through the tricuspid valve into the right ventricle. Once this occurs the right ventricle contracts and pushes the blood through the pulmonic valve into the pulmonary artery. The oxygen rich blood is then returned from the lungs to the left sides of the heart and into the left atrium. The contract of the muscle of the left atrium pushes the blood out into the left ventricle. Finally once the left ventricle fills with blood the muscle walls contract pushing blood into the aorta and throughout the body (Thibodeau, 2008).…

    A deoxygenated red blood cell coming from the body would enter the heart from the vena cava into the right atrium. It would then go into the right ventricle through the tricuspid valve. From the right ventricle, it would be pumped to the lungs through the pulmonary artery. The red blood cell would be oxygenated in the lungs and would return to the left atrium through the pulmonary vein. From the pulmonary vein, it would go through the bicuspid valves into the left ventricle and the left ventricle would pump it through the aorta to the rest of the body.…

    Blood enters the heart 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, and into the left ventricle that pushes blood to the body through the aortic valve. Once blood leaves the heart it is in the aorta where it flows to various parts of the body” (Whitlock, J. 2017).…

    The blood then travel to the lungs where it will receive the oxygen to continue the process of circulation. Later, it drains out of the lungs via the pulmonary veins and then travels into the left atrium. While the blood is forced out through the aortic semilunar valve and into the aorta. The aorta and its branches carry blood to all the tissues of the body system. Reference, Essential of Human Anatomy and Physiology, 2012, by Elaine N.

    The function of the heart is to pump blood throughout the body. The heart pumps blood containing oxygen from the lungs to body. It passes blood without oxygen back to the lungs for more oxygen. The heart has four chambers; the two upper chambers are called atriums, and the two lower chambers are called ventricles. The left atrium is located above the left ventricle, and they are separate by a valve called the mitral valve. The…

    The heart lies in the thoratic cavity, organs associated with the heart are inferiorly, the hearts apex rested on the tendon of the diaphragm, superiorly, the great blood vessels, posteriorly the oesophagus, trachea and the left and right bronchus, laterally, the lungs and anteriorly the sternum and ribs. (Waugh& Grant 2014). The heart provides a constant blood circulation action and the blood vessels provide a network for the blood flow. The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body, ( www.le.ac.uk) the right side of the heart pumps blood to the lungs (pulmonary circulation) and the left side receives oxygenated blood and supplies it to the rest of the body (systemic circulation). There are three types of blood vessel, arteries, capilleries and veins. Blood is pumped from the heart through the arteries at high pressure which could damage the tissue so it needs to go through the capillaires which are smaller low pressure blood vessels that are responsilbe for providing oxygen to the tissues, they also absord excess carbon dioxide and then deliver the blood into the veins which then supply the blood back to the heart. The heart generates its own electrical impulses, it does not rely on any other external mechanisn to make it beat. A normal heart rate is 60-80 times per minute, factors which can decrease or…

    The path blood take from the right femoral vein to lower lobe of the right lung via the pulmonary artery is as follows; we start in the right femoral vein which is located in the thigh and travel to the right external iliac vein. Blood from the femoral vein emptiness in the inferior vena cava but first must travel through the external iliac. The iliac vein joins with the inferior vena cava. The inferior vena cava takes deoxygenated blood form the lower limbs of the body to the right atrium (Thibodeau, Patton, 2008.). Following the inferior vena cava we travel in to the right atrium of the heart. The purpose of right atrium of the heart is to receive deoxygenated blood from the body through the inferior vena cava and pump it into the right ventricle (MedicineNet.com, 2012). Once we are ready to leave the right atrium we go into the right AV valve (AV is atrioventricular or cuspid, (Thibodeau, Patton, 2008.).The AV valve stops blood from flowing backwards and every time the heart beats the valve opens and closes. The AV valve allows blood to flow into the right ventricle. But before blood goes into the right ventricle it has to travel through the tricuspid valve. The tricuspid valve along with AV and SL are all structures that prevent blood from flowing backwards (Thibodeau, Patton, 2008.). So we now know that the right ventricle receives deoxygenated blood from the right atrium, but what we don’t already know is that the right ventricle sends the... [continues]…
