The characteristics of the human heart the muscle that maintains the circulation of blood

Circulatory System Diagram The circulatory system is the most vital systems of your body that is required for the optimal distribution of oxygenated blood to all the body organs and tissues.

The characteristics of the human heart the muscle that maintains the circulation of blood

The SVC collects blood from the upper half of the body. The IVC collects blood from the lower half of the body. When the RA contracts, the blood goes through the tricuspid valve 4 and into the right ventricle RV 5. When the RV contracts, blood is pumped through the pulmonary valve 6into the pulmonary artery PA 7 and into the lungs where it picks up oxygen.

Why does it happen this way? Because blood returning from the body is relatively poor in oxygen. It needs to be full of oxygen before being returned to the body. So the right side of the heart pumps blood to the lungs first to pick up oxygen before going to the left side of the heart where it is returned to the body full of oxygen.

When the LA contracts, blood travels through the mitral valve 10 and into the left ventricle LV The LV is a very important chamber that pumps blood through the aortic valve 12 and into the aorta The aorta is the main artery of the body. It receives all the blood that the heart has pumped out and distributes it to the rest of the body.

The LV has a thicker muscle than any other heart chamber because it must pump blood to the rest of the body against much higher pressure in the general circulation blood pressure. Here is a recap of what we just discussed. Blood from the body flows:The coronary circulation consists of the coronary arteries, which branch off of the aorta and carry oxygen-rich blood to the heart muscle; and coronary veins, which carry deoxygenated blood to the coronary sinus, which empties into the right atrium.

Other problems with the heart and blood vessels include the following: Blood clots; Deep vein thrombosis; Thrombophlebitis; Peripheral vascular disease, resulting in intermittent pain in the legs when walking (claudication) Varicose veins; Aneurysms may develop in one of the major arteries from the heart or in the brain.

Aneurysms are an abnormal widening or ballooning of a part of an artery due to weakness . The human heart has four valves.

The ones on the right side of your heart are called the tricuspid valve and the pulmonary valve, while the ones on the left are the mitral valve and the aortic valve. As the heart beats, it pumps blood through a system of blood vessels, called the circulatory system.

The vessels are elastic tubes that carry blood to every part of the body. Jul 06,  · Massage can help not only to increase blood flow in the areas being massaged, but also to clear out any toxins that may be lingering from having had insufficient blood flow to that area.

You can also ask your massage therapist about essential oils such as rosemary that may help to improve blood 1M. Hormone Function: Constricts blood vessels in skin, kidneys and gut which increases blood supply to heart, brain and skeletal muscles and leads to increased heart rate & blood pressure; Stimulates smooth muscle contraction; Raises blood glucose levels which increases available energy.
