The Heart Research Paper
The heart is one of many vital organs of the human body. To be more precise, the heart is a muscle about the size of a fist, that never rests (unless the person is dead) from working for the body. The purpose of the heart is to circulate oxygen carrying blood to parts throughout the human body, feeding the cells and keeping the person alive.
The heart circulates blood by “pumping” the blood throughout the body, noticeable by the beating. The process goes as follows; oxygen and nutrient deprived blood enters the right chamber of the heart, where the blood would then be pumped away to be refilled with oxygen. The new, oxygen and nutrient filled blood would then enter the opposite chamber on the other side of the heart where the blood would be

The heart is also divided into two halves, with two chambers in each of them. The top, smaller chambers are called atriums, and the larger chambers below the atriums in the heart are called ventricles. In the heart, the chambers are used to separate the starved blood from the full blood. The oxygen deprived blood enters the right atrium via veins , and would then go to the right ventricle to be pumped to the lungs, where the full blood is then pumped into the left atrium, and would then go into the left ventricle, where the blood is then pumped back out throughout the …show more content…
The left atrium is one of two atria of the heart, and functions as receiving refilled/oxygenated blood, entering the heart from the lungs through the left coronary artery, which branches from the aorta. The left atrium pumps blood into the left ventricle, which would in turn pump the new, refilled blood back out into the body.
The right ventricle is one of the four main chambers in the heart, made of muscle, and is located below the right atrium. The right ventricle is also one of two ventricles in the heart, and functions as pumping the deoxygenated blood coming from the right atrium away to the lungs. In a normal heart, the right ventricle’s wall is less thick than that of the left ventricle. This is because the right ventricle pumps blood to the lungs only, whereas the left ventricle has to pump blood throughout the entire body constantly. This means the right ventricle has less work and pressure than the left
Northern Pintail: Skeletal System
1436 Words | 6 PagesThe Pintails heart is like a mammals consisting of four chambers, two ventricles and two atria. The left ventricle pumps blood to all major organs in the body and throughout the rest, only excluding the lungs. This causes the left ventricle to be larger and more muscular. The lungs are fed blood from the right ventricle, which is the only the only function of that ventricle. The oxygenated blood coming from the lungs is fully separated from the oxygenated blood coming from other parts of the body.
Hypoplastic Left Heart Syndrome Case Study
543 Words | 3 PagesHypoplastic Left Heart Syndrome has many factors, stages and severities of the disease which could predict an outcome differently for each individual case. However if left untreated HLHS can be fatal. The left side of the heart is unable to supply blood to the rest of the body therefore the right side of the heart has to work harder to compensate for it. The right ventricle can support this circulation but will eventually cause right sided heart failure. Babies have two routes that can help support and carry blood between the left and right ventricles.
List The Structures And Functions Of The Respiratory System
730 Words | 3 PagesExplain the pathway of blood starting with leaving the left ventricle and ending with entering the left ventricle including the valves. Tricuspid has a three-leaved appearance, it is located between the right atrium and the right ventricle. It closes when the atrium is filling, and it opens when it empties blood into the right ventricle. The pulmonary semilunar valve is located between the right ventricle and the pulmonary arteries. It opens when the right ventricle empties blood going to the lungs.
Persuasive Essay On Open Heart Surgery
1887 Words | 8 Pages“An average heart has four chambers; two upper, called the atria and two lower, called the ventricles. The right side of the heart receives blood that is returning from the body. This oxygen-lacking blood arrives in the right atrium, where it is pumped into the right ventricle. The right ventricle sends the blood to the lungs, where it is picks up plenty of oxygen. This oxygen-rich blood then enters the left atrium and is pumped into the left ventricle, which pumps blood through the aorta to all the organs and tissues of the body” (Blaser).
Lewis Washkansky Case Summary
386 Words | 2 PagesThen a doctor puts antiseptic over your skin, and makes a cut going down your chest to expose the diseased heart. Tubes are placed in your chest to keep the blood pumping through your body. When the old heart is taken out, the new heart is sown in place. Once the new heart is in, it will begin to beat, and a doctor will monitor it until he/ she is sure the heart is functioning properly.
Mitral Valve Research Paper
1071 Words | 5 PagesDeoxygenated blood is fed into the right atrium, pulled down into the right ventricle and then pumped to the heart along the pulmonary artery to the lungs. Once passed through the lungs, the now newly oxygenated blood is fed into the left atrium via the pulmonary vein and drawn down into the left ventricle. In order for the maximum volume of newly oxygenated blood to be then pumped out of the heart, via the aorta, to the rest of the body, the valve must open wide enough to allow the blood to make it into the ventricle, and close firmly enough to ensure that there is no backflow. If this does not happen, the maximum volume of oxygenated blood does not reach the rest of the body, and the system becomes inefficient as the cardiovascular system has to then work harder and faster to get the same volume of oxygenated blood to the surrounding body. This takes more energy, which could otherwise be better used.
Case Study Cardiogenic Shock
1075 Words | 5 PagesBecause of this inability to contract effectively, the rest of the vital organs receive inadequate amount of blood resulting to inadequate tissue perfusion. There are two types of left-sided HF; systolic and diastolic failure. Systolic failure happens when the left ventricle doesn’t have the enough energy to pump normally the blood to the general circulation. As for diastolic failure, the left ventricle loses the ability to fill itself with blood during resting period resulting to inadequate amount of blood to be pumped out to the circulation (Weinrauch, 2008). The diastolic dysfunction will eventually lead to right-sided heart failure.
Bileaflet Valve Research Paper
1165 Words | 5 PagesBecause of this the blood goes in through three different streams and then later meets up, which causes stress for the heart. A lot of stress on an already weak heart can cause major damage and possibly kill the patient. The heart can only withstand a certain amount of velocity of blood or else it will deteriorate the tissue causing the heart to start losing its function. The tissue of the left ventricle is very thick which allows it to take the pressure of the blood and to push blood to the rest of the body, but the right ventricle is not made to withstand high pressure or high velocity, meaning that problems would
Cardiovascular System: Heart Valve Disease
223 Words | 1 PagesWhen the ventricles are full, the tricuspid and mitral valves shut which prevents blood from flowing back into the atria while the ventricles contract. As the ventricles begin to contract, the pulmonic and aortic valves are forced open and blood is pumped out of the ventricles.
Anatomical Structure Of The RV
143 Words | 1 PagesScientists believed that the right ventricle had little to no role in cardiac mechanical function. However, as scientists did more research they found that the right ventricle played an important role in cardiac function. The scientists conducting this research wanted to better understand the structure and function of the RV. They studied the anatomical structure of the RV and discovered that RV has a more elaborate anatomical structure than that of the LV. The RV fibers are composed of several layers of muscle, giving the RV its shape.
2 Ventricles Research Paper
170 Words | 1 PagesA septum in the heart is located between the left and right ventricle chambers. The septum is a muscular wall that separates the deoxygenated blood in the right ventricle from the oxygenated blood in the left ventricle. A damaged septum is commonly called a ‘Ventricular Septal Defect’ and describes a condition where there is a hole between the 2 ventricles, the oxygenated blood from the left, flows into the right ventricle instead of being pumped to the body. The main cause of a damaged septum between the 2 ventricles, is being born with one. As a result of a damaged septum, the heart has to pump a lot harder for the oxygenated blood to reach all over the body.
Heart Rate Relationship
485 Words | 2 PagesThe right ventricles only function is to pump blood into pulmonary circulation for the lungs, while the left ventricle pumps blood throughout the whole of the of the body. Describe the structure and function of the different valves within the heart: Tricuspid valve: This is found in-between the right atrium and the right ventricle. Pulmonary valve: This is found in-between the right ventricle and the pulmonary artery. Mitral valve: This is found in-between the left atrium and the left ventricle.

Mammalian Heart Dissection Lab Report
1584 Words | 7 PagesThe objective of this experiment is check how heart chambers, vessels and valves of the heart help the heart to achieve its function of pumping blood all over the body. In addition, this experiment would help us understand the double circulation of blood and reasons why it is vital for mammalian organisms. Due to the complexity of mammalian organisms, the exchanges of substances such as oxygen, nutrients and hormones cannot rely on diffusion itself (Kent, 2013). The transportation
