- heart works. The heart is one of the most important organs in the human body, continuously pumping blood around our body through blood vessels. Your heart is located in your chest and is well protected by your rib cage. The study of the human heart and its various disorders is known as cardiology.

- The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, as well as assists in the removal of metabolic wastes. In humans, the heart is located between the lungs, in the middle compartment of the chest.

Heart The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, as well as assists in the removal of metabolic wastes. The heart is located in the middle compartment of the chest. In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria; and lower left and right ventricles. Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart.

- After this, the heart muscle relaxes before the next heartbeat. This way, blood can fill up the heart again. The heart's right side and left side have separate functions. The right side collects oxygen-poor blood from the body then pumps it to the lungs where it can pick up oxygen and release carbon dioxide.

The Human Heart If the heart ever ceases to pump blood the body begins to shut down and after a very short period of time will die. The heart is essentially a muscle(a little larger than the fist). Like any other muscle in the human body, it contracts and expands. Unlike skeletal muscles, however, the heart works on the All -or-Nothing Law. That is, each time the heart contracts it does so with all its force. In skeletal muscles, the principle of gradation is present. The pumping of the heart is called the Cardiac Cycle, which occurs about 72 times per minute. This means that each cycle lasts about eight-tenths of a second. During this cycle the entire heart actually rests for about four-tenths of a second. Make-up of the Heart.

Circulatory System Organs and Their Functions The heart is the central organ of the circulatory system, and pumps blood into the blood vessels which carry it to all the body parts. All these events occur with each heartbeat. The average heart rate in a normal person is 72 beats per minute, so one can imagine the speed at which blood flows through the body.

Circulatory System Organs and Their Functions Circulatory System Organs. The human circulatory system comprises the heart, blood and blood vessels which help in transferring essential nutrients and blood throughout the body. This Buzzle article will give you in depth information about this essential mechanism, and the various circulatory system organs.

Heart, How It Works Heart, How It Works. The normal heart is a strong, muscular pump a little larger than a fist. It pumps blood continuously through the circulatory system. Each day the average heart beats (expands and contracts) 100,000 times and pumps about 2,000 gallons of blood. In a 70-year lifetime, an average human heart beats more than 2.5 billion times. The circulatory system is the network of elastic tubes that carries blood throughout the body.

Heart The heart is a muscular organ that pumps blood throughout the body, with a rhythm determined by a group of pacemaking cells in the sinoatrial node. These generate a current that causes contraction of the heart, traveling through the atrioventricular node and along the conduction system of the heart.

Heart The heart functions as a pump in the circulatory system to provide a continuous flow of blood throughout the body. This circulation consists of the systemic circulation to and from the body and the pulmonary circulation to and from the lungs.

- The human circulatory system is really a two-part system whose purpose is to bring oxygen-bearing blood to all the tissues of the body. When the heart contracts it pushes the blood out into two major loops or cycles.

The Cardiovascular System: Mechanics and Dynamics The heart is a specialized organ, and the only one in the body made of cardiac muscle. Heart cells are called cardiomyocytes and make up muscle fibers that conduct electrical …impulses. The function of the heart, which is to keep blood flowing throughout the body, is controlled by involuntary areas of the brain.

Human Heart: Anatomy, Function & Facts The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes. The tissues of the body need a constant supply of nutrition in order to be active, said Dr. Lawrence Phillips, a cardiologist at NYU Langone Medical Center in New York.

- | About the Heart. Your heart is a marvel of nature that pumps life-giving, oxygen-rich blood throughout the body for use by every cell. Upon use by the body, the heart returns the oxygen-depleted blood to the lungs, where it receives more oxygen, to again be pumped throughout the body.

Cardiac Cell Functions The heart functions as the motor of the circulatory system, which consists of the heart, blood vessels and blood.

The Heart as a Pump The function of the heart as a pump is to supply the body with constant blood flow. As cardiac output is dependant on both heart rate and stroke volume, either can be manipulated to effect change in blood supply.

- Heart perform these functions by collecting blood from a lack of oxygen throughout the body and pumps it to the lungs, where the blood picks up oxygen and dispose of carbon dioxide; heart then collects oxygen-rich blood from the lungs and pumps it to tissues throughout the body.

Basic anatomy and function of the heart Heart Anatomy. The heart is a muscular organ that pumps blood to all the tissues in your body through a network of blood vessels. The right side of the heart pumps blood through the lungs where it picks up oxygen. The left side of the heart receives the blood containing oxygen and pumps the blood to the rest of your body.

Heart Anatomy The heart and circulatory system make up your cardiovascular system. Your heart works as a pump that pushes blood to the organs, tissues, and cells of your body. Blood delivers oxygen and nutrients to every cell and removes the carbon dioxide and waste products made by those cells.

- The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it into the various arteries (which provide oxygen and nutrients to body tissues by transporting the blood throughout the body).

Heart The heart is the body's engine room, responsible for pumping life-sustaining blood via a 60,000-mile-long (97,000-kilometer-long) network of vessels. The organ works ceaselessly, beating 100,000 times a day, 40 million times a year—in total clocking up three billion heartbeats over an average lifetime.
