The Heart Arteries, Veins, and Capillaries The Circulatory System Arteries- these blood vessels transport blood away from the heart to the rest of the body. Veins-these blood vessels transport blood back to the heart. Capillaries- tiny blood vessels that are instrumental in getting oxygen into tissues and organs of the body. http://revisionworld.co.uk/a2-level-level-revision/biology/physiology-transport/human-circulatory-system The heart pumps blood to the entire body, making sure oxygen and nutrients get everywhere they’re needed http://www.google.com/imgres?q=circulatory+system&hl=en&biw=1920&bih=880&gbv=2&tbm=isch&tbnid=sMo9EL35r4yerM:&imgrefurl=http://www.naturalhealthschool.com/8_1.html&docid=8oQbkUcjARCuJM&imgurl=http://www.naturalhealthschool.com/img/heart.gif&w=588&h=560&ei=xtWWT-yNAdT1ggftrs0p&zoom=1&iact=hc&vpx=614&vpy=548&dur=5456&hovh=219&hovw=230&tx=142&ty=108&sig=116537900337485880858&page=1&tbnh=131&tbnw=138&start=0&ndsp=68&ved=1t:429,r:47,s:0,i:237 Josh Easley 4/23/12
Red Blood Cells The Blood Nutrients in the Blood The blood is made up of two distinct components: Plasma: It’s 90% water, and 55% of the blood volume. Plasma is the vehicle for many vitamins and minerals, as well as antibodies of the immune system, in the bloodstream. If plasma were missing, blood would stop flowing. Cellular Components: It is 45% of the blood volume and contains red blood cells, white blood cells, and platelets. Platelets aid in blood clots in the event of a wound. http://www.google.com/imgres?q=red+blood+cells&num=10&hl=en&gbv=2&biw=1920&bih=880&tbm=isch&tbnid=UP_fxmIQfl-SdM:&imgrefurl=http://www.fi.edu/learn/heart/blood/red.html&docid=QbwyVeKXFtSGqM&imgurl=http://www.fi.edu/learn/heart/blood/images/red-blood-cells.jpg&w=400&h=270&ei=nNyWT7LPF8KBgAf_x8HhDQ&zoom=1&iact=rc&dur=294&sig=116537900337485880858&sqi=2&page=1&tbnh=104&tbnw=144&start=0&ndsp=55&ved=1t:429,r:0,s:0,i:133&tx=79&ty=57 http://www.google.com/imgres?q=bloodstream&num=10&hl=en&gbv=2&biw=1920&bih=880&tbm=isch&tbnid=gXV6NXGOhSsO5M:&imgrefurl=http://visualparadox.com/wallpapers/bloodstream-wide.htm&docid=pfdQo49mmoThtM&imgurl=http://visualparadox.com/images/linking-not-allowed/bloodstream-wide.jpg&w=1440&h=900&ei=x-GWT9nFGsmr2AXyq6jtDQ&zoom=1&iact=hc&vpx=580&vpy=186&dur=522&hovh=87&hovw=139&tx=166&ty=95&sig=116537900337485880858&sqi=2&page=1&tbnh=87&tbnw=139&start=0&ndsp=60&ved=1t:429,r:4,s:0,i:89 The red blood cells have a compound called hemoglobin, which is necessary for the red blood cells to perform their function: carrying oxygen to the body’s tissues and carbon dioxide away to be excreted. Hemoglobin also gives the red blood cells, and blood, its red color. • Oxygen • Carbon Dioxide • Vitamins • Minerals • Water • Glucose (Sugar) http://www.google.com/imgres?q=blood+components&num=10&hl=en&gbv=2&biw=1920&bih=880&tbm=isch&tbnid=ZFlOr5DxubACtM:&imgrefurl=http://www.jonbarron.org/heart-health/anatomy-blood-water-immune-system&docid=v_IFyBQuC8mk3M&imgurl=http://www.jonbarron.org/sites/default/files/images/blood_components.gif&w=389&h=303&ei=tN-WT42zHYau2AXA6szeDQ&zoom=1&iact=rc&dur=230&sig=116537900337485880858&sqi=2&page=1&tbnh=103&tbnw=132&start=0&ndsp=58&ved=1t:429,r:1,s:0,i:135&tx=44&ty=41
