System\n\nThe survival of the human bodydepends on a steady supply of foodand oxygen reaching all of its cells.Meanwhile,carbon dioxide andother waste materials produced by thecells must be removed.Thecirculatory system transports thesematerials throughout the body.  \nThe materials are carried in a fluidknown as blood,which travelsthrough a complex system of tubescalled blood vessels.There are threemain types of blood vessels—arteries,veins,and capillaries—and blood ispumped through them by a mass ofmuscles known as the heart.  \nBlood picks up a fresh supply ofoxygen in the lungs before it ispumped to every cell.The oxygen-poor blood then returns to the heartand is pumped to the lungs for moreoxygen.  \nBlood also picks up other importantsubstances,such as nutrients from thedigestive system and hormones fromthe glands,and carries them to partsof the body where they are needed.At the same time,the blood picksup waste products and carries them tothe kidneys,lungs,and skin,whichhelp expel them from the body.  \n◀ One of the heart'schambers pumpsblood containingcarbon dioxide tothe lungs,where itis exchanged foroxygen.The bloodthen flows back toanother of theheart's chambers,and it is pumpedthrough the body,delivering oxygen,nutrients,andchemicals to thecells.The blood alsocarries wasteproducts to theparts of the bodythat will get rid ofthem.  \nA view inside a capillary,showingthe main components of the blood(numbered in the inset).The redblood cells(1)transport oxygen andcarbon dioxide.The white blood cells  \n(2)are part of the body's defensesystem.The platelets (3)help theblood form a clot after an injury.Thecapillary walls (4)are made up ofasingle layer of cells.  \n# The Composition of Blood\n\nOur blood consists of several types ofcells carried around in a yellowliquid called blood plasma.Watermakes up about 90 percent ofplasma,which contains nutrients,proteins,hormones,and wasteproducts in addition to the blood cells.  \nThere are three types of blood cells:red blood cells(erythrocytes),whiteblood cells(leucocytes),and platelets(thrombocytes).Red and whiteblood cells are also known ascorpuscles.  \nRed blood cells look like flattened,doughnut-shaped discs.There are  \n5.5 million in every .4 cubic inch ofblood (about the size of a pinhead).They contain a compound calledhemoglobin,which is rich in iron.Hemoglobin picks up oxygen in thelungs,which turns the hemoglobinbright red.As the blood goes throughthe body,the hemoglobin deliversthe oxygen to the cells in exchangefor the waste product carbondioxide.  \nWhite blood cells are much biggerthan red blood cells.There are between  \n4,000 and 10,000 in every .4 cubic inchof blood.Unlike red blood cells,white blood cells have a nucleus.Mostwhite blood cells can move aroundin the bloodstream,which enablesthem to play an important part inthe body's defense system.","cbCaiiTN03Yein8r","https://ap.wps.com/l/cbCaiiTN03Yein8r","pdf",2802985,"English","# The Circulatory System\n## The Composition of Blood\n## Red Blood Cells\n## White Blood Cells\n## Blood
