________ connected to the left side of the heart, carry blood full of oxygen to the rest of the body.
Some disorders of the heart and blood vessels What are the heart and blood vessels? The heart is a muscular pump that pushes blood through blood vessels around the body. The heart beats continuously, pumping the equivalent of more than 14,000 litres of blood every day. Blood vessels form the living system of tubes that carry blood both to and from the heart. What do the heart and blood vessels do? The heart's main function is to pump blood around the body. Blood carries nutrients and waste products and is vital to life. One of the essential nutrients found in blood is oxygen. The right side of the heart receives blood lacking oxygen (deoxygenated blood) from the body. After passing through the right atrium and right ventricle this blood is pumped to the lungs. Here blood picks up oxygen and loses another gas called carbon dioxide. Q: _____ connected to the left side of the heart, carry blood full of oxygen to the rest of the body. A: Arteries connected to the left side of the heart, carry blood full of oxygen to the rest of the body. Blood carries oxygen and many other substances around your body. Oxygen from your blood reacts with sugar in your cells to make energy. The waste product of this process, carbon dioxide, is carried away from your cells in your blood. Your heart is a single organ, but it acts as a double pump. The first pump carries oxygen-poor blood to your lungs, where it unloads carbon dioxide and picks up oxygen. It then delivers oxygen-rich blood back to your heart. The second pump delivers oxygen-rich blood to every part of your body. Blood needing more oxygen is sent back to the heart to begin the cycle again. In one day your heart transports all your blood around your body about 1000 times. Your right ventricle pumps blood to your lungs and your left ventricle pumps blood all around your body. The muscular walls of the left ventricle are thicker than those of the right ventricle, making it a much more powerful pump. For this reason, it is easiest to feel your heart beating on the left side of your chest. Pacemaker The sequence of each heartbeat is as follows: 1  The sinoatrial node (SA node) in the right atrium is like a tiny in-built 'timer'. 2  The electrical impulse gets to the atrioventricular node (AV node) at the lower right atrium. 3  The AV bundle splits into two - a right and a left branch. 4  The heart then rests for a short time (diastole). Without oxygen and these nutrients, the cells will die. The heart helps to provide oxygen and nutrients to the body's tissues and organs by ensuring a rich supply of blood. Not only do blood vessels carry oxygen and nutrients, they also transport carbon dioxide and waste products away from our cells. The blood supply to the heart. 1  The right coronary artery mainly supplies the muscle of the right ventricle. 2  The left coronary artery quickly splits into two and supplies the rest of the heart muscle. 3  The main coronary arteries divide into many smaller branches to supply all the heart muscle. The major blood vessels that enter the heart are the superior vena cava, the inferior vena cava, and the pulmonary veins. The pulmonary artery and the aorta exit the heart and carry oxygen-rich blood to the rest of the body. On the inside, the heart is a four-chambered, hollow organ. It is divided into the left and right side by a muscular wall called the septum. The most important function of the cardiovascular system (the heart and blood vessels together) is to keep blood flowing through capillaries. This allows capillary exchange to take place. Capillary exchange is the process of nutrients passing into the body's cells and waste products passing out. These are the first arteries to branch off the large artery (aorta) which takes blood to the body from the left ventricle. 1  The right coronary artery mainly supplies the muscle of the right ventricle. 2  The left coronary artery quickly splits into two and supplies the rest of the heart muscle.
