invasive treatment in which our doctor uses heat to remove varicose veins. The heat cauterizes and closes the varicose veins in the legs so that they gradually dry up and disappear. Varicose veins are the result of poor blood circulation usually from the legs back to the heart. This condition is called venous insufficiency and occurs when the valves in the veins become weak and do not help push the blood along. The blood pools in the veins causing them to become swollen and look bulging and twisted. They

Capillaries exchange fluids‚ gasses‚ heat‚ nutrients and wastes to the tissues through diffusion. Capillary walls contain small pores that are selectively permeable allowing only certain molecules to pass in and out. This exchange is controlled by blood pressure through hydrostatic pressure and osmotic pressure. Osmotic pressure is produced by high levels and salts and proteins in the blood. As blood enters the capillary by the arteriole end the blood pressure is higher than the osmotic pressure

Arthropod (crayfish) Dissection Megan Williamson period: 3 4/29/13 Objectives: The purpose of this lab was to study and observe the organs in a crayfish and be able to name them. Introduction: Crayfish belong to the kingdom animilia‚ phylum arthropod and class crustaceans. The body is divided into three parts‚ the body‚ the head‚ thorax‚ and abdomen. The head and thorax are apart of a segment called cephalothoraxes‚ which is covered by the carapace made of chitin

Topic 1: I believe using abbreviations can truly help communications between health care professionals‚ because it makes it easier to convey what you are trying to say. For example‚ instead of saying or writing down “cardiopulmonary resuscitation” you could say “CPR”. This also helps speed up the process when a transcriptionist copies down a report; they don’t necessarily have to write out the full meaning and the physician who reads the report will still have a full understanding of what it

increase in the pressure within the portal vein or one of its branches. Typical portal vein pressure is 5 to 10 millimeters of mercury (abbreviated mmHg). When the pressure exceeds 5 mmHg above inferior vena cava pressure‚ it is characterized as portal hypertension. The portal vein carries nutrient rich blood from the digestive system to the liver. Normally‚ the veins come from the stomach‚ intestine‚ spleen‚ and pancreas. They merge into the portal vein‚ which then branches into smaller vessels and
