BIOS 256 DeVry Week 3 Discussion 1 Nutrients A nutrient is a substance in food that is used by the body to promote normal growth, maintenance, and repair. During metabolism, substances inside body cells are constantly built up or broken down. Let's start this week's discussion with the definition and comparison of glycogenesis, glycogenolysis, gluconeogenesis, and lipogenesis. Which is (are) likely to be occurring (1) shortly after a carbohydrate-rich meal and (2) just before waking up in the morning? BIOS 256 DeVry Week 3 Discussion 2 Cholesterol - The Good, The Bad and the not-so ugly? Which lipoproteins particles contain good and bad cholesterol and differentiate between LDLs and HDLs relative to their structures and major roles in the body? BIOS 256 DeVry Week 4 Discussion 1 Kidneys and Urine The production of urine by the kidneys is a critical function of the body. Let's begin this week with some gross anatomy of the kidneys, including tissue layers, major anatomical landmarks, and the primary filtration unit of the kidneys! BIOS 256 DeVry Week 4 Discussion 2 The Glomerulus What is Glomerular Filtration? How is the Glomerular Filtration Rate (GFR) determined? What interacting controls stabilize the GFR? This section lists options that can be used to view responses. BIOS 256 DeVry Week 5 Discussion 1 Fluid & Electrolyte Homeostasis Explain what is meant by the terms fluid balance, electrolyte balance, and acid-base balance, and discuss their importance for homeostasis. List the most frequent threats to acid-base balance, and explain how the body responds when the pH of body fluids varies outside normal limits. BIOS 256 DeVry Week 5 Discussion 2 Electrolytes and Aging Compare the mechanisms by which sodium, potassium, calcium, and chloride ion concentrations are regulated to maintain electrolyte balance. Compare the effects of aging on fluid, electrolyte, and acid-base balance. BIOS 256 DeVry Week 6 Discussion 1 Reproductive Systems
What are the major differences between the male and female reproductive systems? And here's a tougher question— what are the similarities? Which structures are homologous vs which structures are derived from the same embryonic tissues? BIOS 256 DeVry Week 6 Discussion 2 Meiosis Outline the processes of meiosis focusing on spermatogenesis and oogenesis. BIOS 256 DeVry Week 7 Discussion 1 Development Let's discuss the process of fertilization, cell differentiation, and the growth and development that follows during the embryonic period of development - each of you should focus on one aspect of this process and describe it in detail BIOS 256 DeVry Week 7 Discussion 2 Trimesters Outline the three major prenatal periods, describe the events associated with each, and explain how the three germ layers participate in the formation of extra-embryonic membranes.
