1) Eddie, an overweight 40-year-old, decides it’s time for his first physical in ten years. He has no history of heart issues, but his father died of a myocardial infarction at age 41 and his mother is diabetic. What tests would the MD order to get a read on his heart? The doctor would also tell him to take a daily over the counter anticoagulant. What should he buy at the drug store?
2) Explain why mature red blood cells cannot undergo mitosis.

Explain why Jay was infertile. Ectopic pregnancy Jean, a 23-year-old optician, was rushed into hospital with severe lower abdominal pain and low blood pressure. Examination and tests revealed that Jean had raised serum levels of human chorionic gonadotropin, blood in her peritoneal cavity, and an ectopic pregnancy. The embryo had implanted into the anterior wall of her rectum and had eroded a branch of the superior rectal artery causing an intra-abdominal bleed

Bobby, a 72-year-old retired male went to his doctor, complaining of leg pain that started in his lower back, ran across the side of his thigh and over the front of his knee. Next, he developed pain that radiated from his back to his front at the chest through the level of his nipples and also at the umbilicus.
A physical and laboratory tests showed hard nodule on his prostate and an elevation in several of the blood tests. His PSA (prostate specific antigen), an enzyme secreted by normal prostate tissue was very high. Alkaline phosphatase was also elevated, an indication of bone involvement.
A bone scan was ordered to visualize the bone involvement.
Usually prostate cancer's growth is initially influenced by the presence of testosterone. If testosterone is removed by castration, the cancer will often shrink for some period of time before the remaining fraction of testosterone-independent cancer cells grow.
Bobby was not interested in castration and asked if there was another form of treatment. He was treated was a single shot of a drug which is slowly released into the body over a three month time period. Within that time the patient noticed marked relief in his pain.
Why would the scan show bone abnormalities? What would cause it?
