The Dichotomy Of Deoxygenated Blood
Your heart is basically 2 very strong pumps. The pump on the right hand side receives second hand blood that has already sent its oxygen around the whole and delivers this blood to the lungs to pick up 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 right ventricle, across the the pulmonary valve

    It then continues as the right external iliac which comes together to the inferior vena cava, also known as the posterior vena cava. It is a vein that carries deoxygenated blood from the lower body to the heart. From there, the inferior vena cava leads to the right atrium of the heart. The right atrium is only one of the four hollow chambers of the heart. It receives blood from the superior vena cava and the inferior vena cava. The blood that comes through these veins is low in oxygen (“Right Atrium”, n.d.). After passing through the right atrium, we pass through the right atrioventricular (AV) valve, also called the tricuspid valve, and then we shall go through the right ventricle, lower right-hand chamber of the heart that pumps blood from the right atrium into the pulmonary arteries then to the lungs, to the pulmonary valve, or the pulmonary semilunar valve. The valves of the pulmonary semilunar valve opens when the right ventricle contracts. When the muscles…

    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).…

    We have now arrived to the right atrium of the heart. As you can see looking out of your windows, the right atrium of the heart receives de-oxygenated blood from the body via the superior vena cava and the inferior vena cava. So everything is connected in terms of blood flow so that the blood will return to the right atrium of the heart. You can also see the contractions that the atrium is making. This is due to the sinoatrial node that sends impulses to the cardiac muscle tissue which causes it to contract in a wave-like…

    The myocardium, commonly referred to as the heart, acts as a pump for transporting blood around the body via a collective system, known as the cardiovascular system. This system has various components; blood vessels; mainly arteries, veins and capillaries. The cardiovascular system has four main functions within the body. Firstly to transport dissolved oxygen, hormones, nutrients, salts, enzymes and urea to cells located around various places within the body, whilst at the same time eliminating any waste products such as carbon dioxide and water. Secondly, to protect the body from infection and blood loss. Thirdly, to distribute heat around the body to enable a healthy temperature of 37oc and finally to aid the body to maintain fluid balance. This ‘human pump’ can be regarded as two pumps. The fist sized organ contains two muscular chambers; the upper chamber; the atrium and the lower; the ventricle. The right side of the heart pumps deoxygenated blood from the veins to the lungs for oxygenation, whilst the left side pumps oxygenated blood from the lungs to the body. It is important to note that the two sides are separated by a septum. The blood flows through the heart twice within one cycle, this is known as ‘double circulation’.…

    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 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]…

    Once the red blood cell returns to the heart, it enters through the vana cava (vein) returning the deoxygenated blood from the upper part and the lower parts of the body to the heart. This large veins lead into the right atrium where the pumping heart forces the red blood cells through the tricuspid valve into the right ventricle. The valve stops blood from flowing backwards into the right atrium once it’s in the right ventricle they are then pumped through the pulmonary valve into the pulmonary artery and on to the lungs. The arteries carry blood away from the heart (always oxygenated apart from the pulmonary artery which goes from the heart to the lungs), they have thick, elasticated, muscular walls which allows them to expand (creating pulse) and to deal with the high blood pressure. Once the blood is delivered to the lungs via the capillaries (found in the muscles and lungs, microscopic – one cell thick blood vessels which are also very narrow to create very low blood pressure- adapted to maximise diffusion of gases) within the alveoli, an exchange of gases takes place between the gases inside the alveoli and the blood.Blood arriving in the alveoli has a higher carbon dioxide…
