It is placed in the center of your chest cavity. The Four Chambers: - Atrium (Left and Right) -Ventricle (Left and Right) The Heart pumps oxygen-poor blood to the lungs and oxygen-rich blood to the body. Every Living thing has a heart (ex. Mammals, Insects, all living things) The sound the heart creates (e.g. the lub-dub sound) a pumping sound. This is the sound of a beating heart. This is caused by the closing of the valves. Flap like structures called valves make sure that the blood does not travel backwards weighs ten ounces = one sneaker tilted slightly on the left side of your body URL:http://www.mynews.in/News/Health_Tip:_At_the_Heart_of_a_Stent_N33158.html Date Accessed: 9/24/10 Image Name: Heart [Online Image] Blood : Blood The entire human body contains about 5L of blood. Blood is a connective tissue that is made up of two types of cells, cell parts and plasma. Blood is created by 55% Plasma, White Blood Cells and Platelets <1% and Red Blood Cells 45%. * Red Blood Cells: -Red Blood Cells contains a protein called "hemoglobin". Hemoglobin produces the red color, and clings to the oxygen you inhale. the shape of the red blood cell corresponds to carrying nutrients and oxygen in an out of the bloodstream * White Blood Cells: - There is one white blood cell for about every 5000 red blood cells a drop of blood contains about 5 million red blood cells White Blood Cells fight pathogens, Bacteria.

Veins -Direct blood straight back to the heart -Valves keep the blood from flowing backwards Capillaries -The smallest blood vessel in the body, extremely narrow, -Blood vessels must go in a single line in order to pass through .

It killed about 925,000 people every year, involving more than 150,000 people under the age of 65. - However now a days medicine helps some patients avoid lethal heart diseases.

Anemia: Anemia is a condition in which the blood lacks the normal amount of red blood cells, hemoglobin, or both. Hemorrhagic: Hemorrhage is the medical term for bleeding, usually excessive bleeding. There are two main types of hemorrhagic strokes: intracerebral hemorrhage and subarachnoid hemorrhage. MLA (Modern Language Association) style: Baldini, Mario, and William Dameshek. "Blood." Encyclopedia Americana. 2010. Grolier Online. 23 Sept. 2010 <http://ea.grolier.com/article?id=0050970-00>. – Both Anemia and Hemorrhagic Polycythemia: Proportion of blood volume that is occupied by red blood cells increases. It is the opposite of anemia, in which there are too few red blood cells. Causes lung disorders. MLA (Modern Language Association) style: Beutler, Ernest. "Polycythemia." Encyclopedia Americana. 2010. Grolier Online. 23 Sept. 2010 <http://ea.grolier.com/article?id=0317750-00>. Leukemia: Leukemia is a group of cancer starting from the bone marrow an the lymphatic tissue. Leukemic cells displace the normal red and white blood cells causing anemia, blood clotting, hemorrhaging and severe infections.
