There are many various conditions and diseases affecting the endocrine system. Here we will discuss several and describe the endocrine gland‚ hormone‚ target tissue‚ symptoms‚ causes‚ and treatment options. The human chorionic gonadotropin (hCG) test is done to check for the hormone hCG in blood or urine (Staff‚ 2012). The hCG hormone is made during pregnancy by the placenta or can be abnormally made by certain tumors. The hCG test can be performed to test if a woman is pregnant or not‚ as part

Metabolism “Metabolism is the set of chemical reactions that happen in living organisms to maintain life. These processes allow organisms to grow and reproduce‚ maintain their structures‚ and respond to their environments” (Metabolism). Metabolism breaks down the food that we eat‚ transforming it into energy for our bodies. Metabolism is broken down into two categories Anabolism and Catabolism‚ which help aid in the chemical reaction process. Specific proteins in the body control the chemical

I. INTRODUCTION Hydatidiform Mole (H-mole or Gestational trophoblastic disease) is abnormal proliferation and then degeneration of the trophoblastic villi (Garg & Giuntoli‚ 2007). As the cells degenerate‚ they become filled with fluid and appear as clear fluid-filled‚ grape-sized vesicles. The embryo fails to develop beyond a primitive start. Abnormal trophoblast cells must be identified because they are associated with choriocarcinoma‚ a rapidly metastasizing malignancy. (Pillitteri‚ 2010)
