myocardium loses its ability to pump enough blood to meet the body’s metabolic needs and is generally accompanied by fluid accumulation in the body tissues‚ especially the lungs. The build–up of fluid affects the normal function of the heart‚ pulmonary circulation‚ blood pressure‚ the distribution of oxygen and nutrients‚ and electrolyte balance. Where oedema occurs in the body depends on the part of the heart that is affected by heart failure. Heart failure is almost always a chronic‚ long term condition
Premium Blood Heart
When your heart contracts and forces blood into the blood vessels‚ there is a certain path that the blood follows through our body. The blood moves through pulmonary circulation and then continues on through systemic circulation. Pulmonary and systemic are the two circuits in the two-circuit system of higher animals with closed circulatory systems. As the heart pumps‚ blood is pushed through our body through the entire circulatory system. Oxygenated blood is pumped away from the heart to the rest

Capillary From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search For other uses‚ see Capillary (disambiguation). [pic] [pic] Blood flows from the heart to arteries‚ which branch and narrow into arterioles‚ and then narrow further still into capillaries. After the tissue has been perfused‚ capillaries branch and widen to become venules and then widen more and connect to become veins‚ which return blood to the heart. Capillaries (pronounced /ˈkæpəˌlɛri/) are the smallest of a body

vessels entering or leaving it. Veins enter the atria‚ and arteries leave the ventricles” (Strech‚ Beryl; Whitehouse‚ Mary;‚ 2010) The pulmonary circulation is the circulation to and from the lungs. The pulmonary artery carries deoxygenated blood this leaves the right ventricle to go to the lungs and the blood is separated between the two lungs and the pulmonary blood then carries oxygenated blood and then enters the left atrium. The main artery which is located leaving the left ventricle is called

is located about 1.5 cm to the left of the midsagittal plane. Located above the heart are the great vessels: the superior and inferior vena cava‚ the pulmonary artery and vein‚ as well as the aorta. The aortic arch lies behind the heart. The esophagus and the spine lie further behind the heart. II. FUNCTIONS OF THE HEART The role of circulation is to: 1. Continuously deliver oxygen‚ nutrients‚ hormones‚ and antibodies to organs‚ tissues and cells throughout the body in response to varying

attached to the heart‚ and what does it do? The largest vessel that is attached to the heart is the aorta. This carries nutrient filled blood to the rest of the body. 3. What is pulmonary circulation? Pulmonary circulation is the circulation of blood from the heart to the lungs through the pulmonary artery and pulmonary veins. The heart pumps deoxygenated blood from the heart to the lungs and then the blood is sent back being oxygenated‚ where it is then pumped to the rest of the body. 4
