Describe The Functions Of The Heart

Inside the heart the four chambers were clearly defined and hollow. The wall on the left side of the heart was much thicker and firmer than the wall on the right side. The wall on the right side was very thin. The valves appeared stringy, stretchy and very long.

The heart is located between lungs and it is protected by the rib cage, it is thought to be the same size as a closed fist. The heart is protected a membrane called pericardium, this membrane contains a film of fluid which helps prevent fiction. Each side of the heart consist of an atrium and a ventricle. The right side of the

Oxygen and nutrients the body requires for function are pumped around this complex network of blood vessels by the heart. At roughly the size of a human fist, the heart is a four-chambered muscle and performs two functions of circulation simultaneously and continuously. Systemic and pulmonary circulation. The heart is made up from three separate layers of cardiac tissue; the outer layer called the pericardium, which is a double sac-like outer covering with serous fluid inside to keep the middle layer, the myocardium from adhering to the outer layer. This middle layer of the heart is the heart muscle which is thicker on the left side, to aid with the pressure needed to sustain systemic circulation. The inner layer of the heart is the endocardium. It’s lining is smooth to help prevent the blood which circulates around the inside of the heart from clotting. The heart is the human body’s in-built pacemaker, and the electrical signals sent through the it cause the heart to contract and relax. This process is triggered by the autonomic nervous system and the contraction and relaxing cycle is

Most heart diagrams show the left atrium and ventricle on the right side of the diagram. Imagine the heart in the body of a person facing you. The left side of their heart is on their left, but since you are facing them, it is on your right.

The heart is a hollow muscular organ. The heart's job is to pump blood through the entire body. This job is important because blood carries oxygen and nutrients from the foods you eat to all the cells of the body. It also carries waste products away from your cells.

Atria: The heart is divided into four chambers that are connected by heart valves, the upper two heart chambers are called atria.

The left side of the heart delivers blood to the rest of the body, whereas the right side of the heart delivers blood to the lungs.

from the ventricles into the atria. On the right side of the heart is the

The heart is about the size of a fist, snuggled in the mediastinum of the body. There’s a fluid-filled cavity called the pericardial cavity. The pericardial cavity is lined with serous membrane called the pericardium, which lubricated the heart and prevent friction. The wall of the heart is made of three layers: epicardium, myocardium, and endocardium. The four chambers of the heart are: the right atrium, left atrium, right ventricle, and left ventricle. The right side of the heart provides pulmonary circulation to the neighboring lungs whereas the left side of the heart pumps blood out to the extremities of the body in the systemic circulatory loop. A system of one way valves prevents blood from flowing backwards back into the

Cardiac muscle (heart muscle) - found in the walls of the heart. It has similarities

* The heart is enclosed by a sac known as the pericardium. There are three layers of tissues that form the heart wall. The outer layer of the heart wall is the epicardium, the middle layer is the myocardium, and the inner layer is the endocardium. The internal

The right side of the heart collects oxygen-poor blood from the body and pumps it to the lungs. The left side of the heart collects oxygen-rich blood from the lungs and pumps it to the body. More specifically, the right atrium collects oxygen-poor blood from the body through two large veins called the superior

There are three layers that are important to the function of the heart these include Fibrous pericardium, parietal pericardium and visceral pericardium. Fibrous pericardium is the outer sac that protects and covers the heart. It keeps the heart in the chest cavity. It also protects the heart from infections and the chance of them spreading into other organs. The particle pericardium insulates the heart. The visceral pericardium is the inner layer that provides pericardial fluid. This is helpful with providing lubrication of the membrane and all the other layers.

The heart is the most important cardiac muscle in the body. The heart is located right under the rib cage, right between your lungs and to the left of the breast bone. The heart is made up of four chambers, there are two upper chambers called atria, and two lower chambers called ventricles. The right side of your heart receives oxygen poor blood and the left side of your heart receives oxygen rich blood. Your blood flows through your heart and lungs in four different stages, each stage is beneficial to your health. The first stage starts off in the right atrium. The right atrium receives oxygen-poor blood and pumps it to the right ventricle through the tricuspid valve. Next, the right atrium then contracts and blood is pumped into the right

The heart is located in the chest between the lungs behind the sternum and above the diaphragm. It is surrounded by the pericardium. Its size is about that of a fist, and its weight is about 250-300 g. Its center is located about 1.5 cm to the left of the midsagittal plane. Located above the heart are the great vessels: the superior and inferior vena cava, the pulmonary artery and vein, as well as the aorta. The aortic arch lies behind the heart. The esophagus and the spine lie further behind the heart.
