It tilts obliquely, a little more to the left than the right and presents a circular base above and an apex below.

The heart gets its energy by oxidizing blood sugars. This released energy, contracts the heart’s many muscle cells, and the four chambers squeeze blood out into the arteries.

Essay on Human Heart: Location, Structure and Other Details (with diagram)
The Heart and Circulation of Blood In this research paper, I will be analyzing the process of blood circulation within the human body. I will be focusing on the pulmonary circuit and the systemic essay on the heart, as well as the relationship with the hepatic portal system. The combination of these systems allows the body to function properly and maintain unconscious homeostasis.
I will also be talking about the effects that fitness and diet have on these processes. The pulmonary circuit passes already-used. WHAT IS HEART? The human heart is a muscular organ that provides a continuous blood circulation through the cycle and is one of the most vital organs in the human body. The heart is divided into four main chambers: the two upper chambers are called the left and right atria and two lower chambers are called the right essay on the heart left ventricles.
There is a thick wall of muscle separating the right side and the left side of the heart called the septum. Fig essay on the heart HUMAN HEART[10] HOW DOES BLOOD FLOW THROUGH. There are two primary circulation loops in the human body known as pulmonary circulation loops and systemic circulation loops.
o Pulmonary circulation loops: is responsible for transporting oxygenate-poor blood from right atrium, to the right ventricle and then to the lung. The blood then picks oxygen in the lung and then returns to the left atrium. o Systemic circulation loops: then systemic circulation loops transport the oxygenate-rich blood from the left atrium to then left ventricle. The heart is the circulatory pump that transports blood to the entire body.
Cardiovascular system has two circulations: systemic and the pulmonary circulations. Pulmonary circulation is the flow of blood between the heart and lungs. Pulmonary circulation starts when the deoxygenated. Anatomy of the heart Name: Rita Attah Tutor: Mark Drummond College: North Herts College Introduction The heart The heart is a muscular organ found in the thoracic cavity between the lungs. The heart is protected by the rib cage, essay on the heart. It is also surrounded by a membrane called the pericardium.
This membrane consists of a thin film of fluid to prevent the heart from friction. The heart consists of double pumps. Each pump is made of two chambers. The upper muscular chamber is known as atrium and. The blood is the essence of life, and is responsible for carrying oxygen and nutrients to various parts of the body, where they are needed.
It also carries toxins away to where it can be broken down. Therefore, blood circulation is an important functionof the body. Poor blood flow has been found to be the cause of several ailments, among which is stroke. Severe headache, essay on the heart, loss of memory and mental focus have also been attributed to poor blood circulation. Poor blood circulation is also. am going to write about the circulatory system of human. There are two types of circulation in circulatory system.
Essay on the heart of all, pulmonary circulation is the part of the circulation, which carries oxygen depleted blood away from the heart, to lungs, essay on the heart, and back to the heart.
At first, in process of this circulation oxygen-depleted blood enters right atrium, and the blood pumped into the right ventricle. Then, the blood pumped to essay on the heart pulmonary valve and goes into the pulmonary artery, and pulmonary.
The heart, blood and blood vessels make up the basis of the cardiovascular system also known as the circulatory system. The average human body contains approximately 5 litres of blood which is carried around the body via a network of blood vessels split into three types; arteries, veins and capillaries.
The arteries are the largest of the three vessels and carry blood away from the heart. Veins carry blood to the heart and are smaller than arteries, then finally the smallest vessels known as capillaries. We have learned that the heart is a complex muscle that pumps blood throughout the body for the purposes of tissue oxygenation and gas exchange waste removal.
We must now discuss the four separate chambers of the heart through which this blood flows through. To start, the two upper, or superior chambers are known as the atria, and the two lower, or inferior chambers are known as the ventricles.
Each half contains a superior. oxygenated blood flows from the heart to body cells, apart from the pulmonary artery that takes the deoxygenated blood to the lungs - Resist the high blood pressure during ventricle systole - maintain the pressure during ventricle diastole - Keep the deoxygenated blood flows from body cells to the heart, except the pulmonary vein that takes the oxygenated blood to the heart, with low pressure - Blood reservoir - Permit fast diffusion and exchange between the blood and body cells - Control blood flow to.

The heart has two sides - the left ventricle and the right ventricle. The artery from the right ventricle pumps blood to …show more content… The venae cavae collects oxygen depleted blood from the body and routes the blood to the right atrium in the essay on the heart. When the right atrium essay on the heart, it pushes blood through the tricuspid valve into the right ventricle. Like the other three heart valves this is a one way valve blood can only flow in one direction.
When the right ventricle contracts, it pushes blood through the pulmonary valve and on into the lungs. Because it does not take much pressure to get blood to the lungs and back, the right side is smaller than the left, essay on the heart.
The essay on the heart side has to work harder pumping blood to the rest of the body. Blood in our arteries is at a high pressure, blood in our veins is at low pressure.
The blood, rich in oxygen, returns from the lungs through the pulmonary veins into the left atrium. To get all the way round blood has to go through the heart twice and this is why it is called a double circulation.
Blood contains red blood cells, white blood cells and platelets floating in a liquid called plasma. The red blood cells contain haemoglobin and carry oxygen. Haemoglobin is a protein which becomes oxyhaemoglobin in the lungs. The white blood cells fight disease by making antibodies and fighting germs. Blood transports these vital materials around the body. Blood plasma contains nutrients, hormones and waste products.

The heart is enclosed in a double walled sac called the Pericardium The heart is the most essential biological structure in the body system; nobody can live without the heart. The major role of the heart is to pump blood throughout all the organs in the body; blood transported by the heart carries oxygen and nutrients around the body and removes all the dangerous wastes The heart is a big muscle with four valves connected together to make a two-stage pump.
