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.
Sep 18, 2019 · What Is a Heart Attack? When a coronary artery becomes blocked (usually by a blood clot), an area of heart tissue loses its blood supply. This reduction of blood can quickly damage and/or kill heart tissue, so quick treatments in an emergency department and/or catheterization suite are necessary to reduce the loss of heart tissue.
This image shows the four chambers of the heart and the direction that blood flows through the heart. Oxygen-poor blood, shown in blue-purple, flows into the heart and is pumped out to the lungs. Then oxygen-rich blood, shown in red, is pumped out to the rest of the body, with the help of the heart valves.

Arteries carry blood away from the heart. The pulmonary artery takes blood from the heart to the lungs. The aorta carries blood from the heart to the body. The large aorta branches into smaller and smaller arteries in order to supply the organs, muscles, and brain with oxygen and nutrient-rich blood.
When a person suffers from a heart attack (ischemic event), the disruption of plaque in the wall of a coronary artery may result in obstruction of flow, causing part of their heart to experience an extreme lack of oxygen. However, one of the most dangerous aspects of a heart attack is the so-called reperfusion period, when blood circulation is ...
Mar 17, 2016 · The heart is an organ which is made from muscle. Organs are a collection of tissues that are specialised for their purpose. Muscle is a type of tissue. The heart is made up of a collection of different tissues such as nervous tissue, connective tissue and cardiac muscle (muscle specialised for the heart) and blood (which is classified as a tissue as it is a collection of cells!).
The aortic valve’s, where the Blood leaves the heart, then it's channeled to the rest of the bod. The arteries, arterioles, and capillaries too bring the oxygenated Blood to the cells. The tissues and the cells trade off waste and CO 2 , which is carried through the venules and the veins
A VSD is a hole in the heart in the region that connects the left ventricle and the right ventricle. At birth, this hole allows large amounts of blood to flow between the two chambers, increase the volume of blood traveling to the lungs and increasing lung pressures, damaging the small blood vessels in the lungs.
