Document Summary
Cardiovascular system: bringing nutrients into body (ex: from intestine to liver, removal of waste products (ex: co2 removal by lungs/ ammonia to liver -> urea -> kidneys, bringing fuel to cells (ex: Glucose from liver to brain: bringing o2 from lungs to. Cells: circulation of hormones (ex: adrenaline from. *hormones = chemical messenger made in 1 organ -> ending up in another organ by traveling by. Cardiovascular system: circulation of immune cells & antibodies made by other organs transported by blood to injury, regulation of. Electrolytes na+/k+/cl: regulation of ph (lungs / kidneys) Ex: ph 7. 4 highly regulated in arterial blood: thermoregulation (ex: exercise. J) h2o balance (exercise = dehydration / overhydration) > total amount of water decrease from sweat &t /ther(cid:373)oregulatio(cid:374) increase during exercise) Cardiovascular system helps lose heat from skin- sweat glands obtain water from capillaries. * when cold -> blood moves away from skin -> vasoconstriction to keep heat.
