Digestion of food continues int he small intestine, where food is completely broken down into a form that be used by the body. nutrients are absorbed through the walls and circulated through the blood stream
  168. The large intestine
    is also called the colon, parts of food that cannot be absorbed by the body are passed as waste products from the small intestine into the large intestine, where the water is absorbed, and whatever remains is passed as stool.

  171. Renal system, and what it consists of
    urinary stystem, filters and excretes wastes from the blood. contains two kidneys, two ureters, which carry the wastes from the kidneys to bladder, one urinarry bladder, which stores the piss, and one urethtra which cariers urine from the bladder and outside the body.
  172. Kidneys
    filter waste from the bloodstream and help control blood pressure regulation
  173. Female reproductive system
    two ovaries, two fallopian tues, the uterus, the vagina and external genitals.
  174. The process of the heart contracting with electrical impulses
    the electric impulse orignates ate the sinoatrial(SA) node and travles the the atrio ventricular(av) node, which is locatd between the ventricles, and finally throught the bodle of his to the purkinjke fibers to the ventricles.

    diaphragm is 60-70 and intercostal picks up the reaminag 30-40
