• artery is a blood vessel that carries blood at a high pressure away from the heart
• aorta is the main artery that takes oxygenated blood away from the heart to the body
• in the circulatory series oxgynated blood is pumped through the pulmonary vein from the lungs and into the left atrium. Carried to the left ventricle and out of the aorta to the rest of the body. Deoxgynated blood is pumped back in through the vena cava from the body and into the right atrium, down into the right ventricle and out the pulmonary artery to the lungs.
• a pacemaker controls the natural resting heart rate of the body and is located in the right atrium
• solutions to coronary heart disease are stents and statins
• coronary heart disease is a condition where the coronary arteries become blocked with fatty material
• the organ system is a group of organs that work together to form organisms
• a cell is the basic building block of all living organisms
• capillary is a very thing blood vessel that is used for exchange of substances
• a tissue is a group of cells with a similar structure and function
• a vein is a blood vessel that carried blood at a low pressure back to the heart
• the vena cava is the main vein that takes deoxygenated blood back to the heart from the body
• the heart is an organ that pumps blood around the body in a double circulatory system
• plasmid are loops of DNA found in the cytoplasm of prokaryotic cells
• blood is a tissue containing red blood cells, white blood cells, plateletes and plasma
• statins are a class of drugs that are used to reduce blood cholesterol levels which slows down the rate of fatty material deposit
• pulmonary vein is the main vein that takes oxygenated blood back to the heart from the lungs
• organs are collection of tissues performing specific functions
• the pulmonary artery is the main artery that takes deoxygenated blood away from the heart to the lungs
• a stent is a tube that can be surgically impanted into blood vessels to keep them open
