The heart works like a pump and beats 100,000 times a day. The heart has two sides, separated by an inner wall called the septum. The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body.
The left side of your heart
The left ventricle of your heart is larger and thicker than the right ventricle. This is because it has to pump the blood further around the body, and against higher pressure, compared with the right ventricle.The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body.
The heart is an amazing organ. It pumps oxygen and nutrient-rich blood throughout your body to sustain life. This fist-sized powerhouse beats (expands and contracts) 100,000 times per day, pumping five or six quarts of blood each minute, or about 2,000 gallons per day.
The upper chambers are called the left and right atria, and the lower chambers are called the left and right ventricles. A wall of muscle called the septum separates the left and right atria and the left and right ventricles. The left ventricle is the largest and strongest chamber in your heart.
Right and left sides of the heart
The right hand side of the heart (shown on the left of pictures and diagrams) pumps blood needing oxygen to the lungs. The oxygen-rich blood enters the left side of the heart which then pumps it around the body to where it is needed.SA node (sinoatrial node) – known as the heart's natural pacemaker. The impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node. The electrical activity spreads through the walls of the atria and causes them to contract. This forces blood into the ventricles.
Heart failure is a chronic long-term condition that gets worse with time. There are four stages of heart failure (Stage A, B, C and D). The stages range from "high risk of developing heart failure" to "advanced heart failure," and provide treatment plans.
Right-sided heart failure is a very serious condition that usually causes severe symptoms, and can cause premature death.
As blood begins to back up behind the failing left ventricle and into the lungs, it will become harder for the right ventricle to pump returning blood through the lungs. Like the left ventricle, the right ventricle will weaken with time and start to fail.
HYPERTENSION. Chronic hypertension is the most common cause of diastolic dysfunction and failure. It leads to left ventricular hypertrophy and increased connective tissue content, both of which decrease cardiac compliance.
Living with Half a Heart. The syndrome is a rare inherited disorder in which the left half of the heart is undersized and cannot perform its function of pumping blood to the body. Without surgery, it is fatal.
Left-sided heart failure symptoms include: Awakening at night with shortness of breath. Shortness of breath during exercise or when lying flat. Chronic coughing or wheezing. Difficulty concentrating.
The right ventricle, or right chamber, moves “used” blood from your heart back to your lungs to be resupplied with oxygen. So when you have right-side heart failure, the right chamber has lost its ability to pump. That means your heart can't fill with enough blood, and the blood backs up into the veins.
Dextrocardia is a rare heart condition in which your heart points toward the right side of your chest instead of the left side. If you have isolated dextrocardia, your heart is located on the right side of your chest, but it has no other defects. Dextrocardia can also occur in a condition called situs inversus.
Deoxygenated blood leaves the heart, goes to the lungs, and then re-enters the heart; Deoxygenated blood leaves through the right ventricle through the pulmonary artery. From the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle. The left ventricle pumps the oxygen-rich blood to the body.
The right side of your heart gets blood from your body and pumps it into your lungs. Oxygen-poor blood flows in through the large veins to the right atrium. Then the blood moves into the right ventricle, which contracts and sends blood out of your heart to pick up oxygen from your lungs.
The largest artery is the aorta, the main high-pressure pipeline connected to the heart's left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries' smaller branches are called arterioles and capillaries.
Blood passes from the right atrium through the tricuspid valve and into the right ventricle. When the right ventricle contracts, the muscular force pushes blood through the pulmonary semilunar valve into the pulmonary artery. The blood then travels to the lungs, where it receives oxygen.
What does your heart do? The purpose of your heart is to pump blood to the organs and tissues of your body that need the oxygen and nutrients it carries. This blood which is in need of oxygen (so-called deoxygenated blood) is sent to your lungs to pick up oxygen and get rid of carbon dioxide.
Blood from right atrium enters right ventricle and pulmonary arteries carry deoxygenated blood from right ventricle to lungs for oxygenation. Two pulmonary veins come from each lung and pass O2-rich blood to left atrium. Blood enters left ventricle from the left atrium.
As deoxygenated blood flows into the right atrium, it passes through the tricuspid valve and into the right ventricle, which pumps the blood up through the pulmonary valve and through the pulmonary artery to the lungs.
Once blood travels through the pulmonic valve, it enters your lungs. Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood. At the same time, carbon dioxide, a waste product of metabolism, passes from the blood into the air sacs.
It pumps oxygen and nutrient-rich blood throughout your body to sustain life. This fist-sized powerhouse beats (expands and contracts) 100,000 times per day, pumping five or six quarts of blood each minute, or about 2,000 gallons per day.
The heart pumps about 1 million barrels of blood during an average lifetime—that's enough to fill more than 3 super tankers.
It pumps about 55-80 ml (1/3 cup) of blood with each beat for adults and around 25-85 ml per beat for children. An adult heart pumps about 6,000-7,500 liters (1,500-2,000 gallons) of blood daily. The average adult body contains about five quarts of blood which continually circulates throughout the body.

- Exercise daily.
The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart.
If your heart beats less than 60 times a minute, it is slower than normal. A slow heart rate can be normal and healthy. Or it could be a sign of a problem with the heart's electrical system. Sometimes, the heart beats so slowly that it doesn't pump enough blood to meet the body's needs.
When your heart is beating too fast, it may not pump blood effectively to the rest of your body. This can deprive your organs and tissues of oxygen and can cause the following tachycardia-related signs and symptoms: Shortness of breath. Lightheadedness.
