2. Chocolate can actually help the circulatorysystem. According
to the Northwest HealthSciences University, chocolate contains
cocoawhich has antioxidants that help protect thecardiovascular
system. The antioxidants helplower blood pressure and help reduce
deathsrelated to cardiovascular disease. A 4-5 gramserving per day
is enough to gain the benefitsfrom the antioxidants found in
cocoa.
3. The main blood vessels areArteries, Veins and
Capillaries
4. Arteries~ Carries blood AWAY form the heart Two main
arteries are pulmonaryarteries and systemic arteries
5. Pulmonary arteriescarry blood from Arteries~the heart to
thelungs where theblood picks upoxygen. Systemic arteriesdeliver
blood tothe rest of thebody. Aorta is the mainsystemic arteryand
the largestartery of thebody. It supplyblood to the head
6. Veins~ Carries blood TO the heart Four main veins are
pulmonary, systemic,superficial, and deep veins.
7. Pulmonary veinstransportsoxygenated bloodfrom the lungs
tothe heart.Veins~ Systemic veinsreturndeoxygenated bloodfrom the
rest ofthe body to theheart. Superficial veins arelocated close to
thesurface of the skinand are not locatednear acorrespondingartery
Deep veins are
8. Capillaries~ Important exchanges of thecirculatory system
occurs here The capillaries are a single cell indiameter to aid
fast and easydiffusion of gases, sugars and othernutrients to
surrounding tissues.
9. Blood is about twice as thick as water, thanks to all the
cells and other bits that float in it.
10. Function of Blood Carries oxygen to cells Carries waste
products like lactic acidaway from cells White Blood Cells fight
againstdiseases in the body
11. Function of Blood Maintaining a good circulation, the
bloodflow keeps the body temperature at around37oC. Blood transport
nutrients from thedigestive system to the cells in our body
Substances like platelets and fibrin in theblood help to clot
wounds
12. Red Blood Cells~ They transport oxygen from the lungsto all
of the living tissues of the bodyand carry away carbon dioxide.
Hemoglobin is the gas that transportproteins and make up 95% of
eachred cell
13. They seek out,identify, and bind White Blood Cells~to alien
proteinon bacteria, viruses, and fungi sothat they can beremoved
They also have thefunction of gettingrid of dead ordying blood
cellsas well as foreignmatter such asdust
14. Platelets~ Platelets work with blood clottingchemicals at
the site of wounds Platelets also fight diseases byreleasing
proteins and kill invadingbacterias
15. Plasma~ As the heart pumps blood to cellsthroughout the
body, plasma bringsnourishment to them and removes thewaste
products of metabolism Metabolism=The chemical and
physicalprocesses continuously going on in thecells of living
organisms. These are theprocesses by which energy and matterare
made available for use by the cellsof an organism. Heat is a
byproduct ofmetabolism.
