Generally, what types of molecules and in which direction (from blood to tubules or tubules to blood) do molecules move during each of the three processes involved in urine formation:
✓ glomerular filtration
✓ tubular reabsorption
✓ tubular secretion
Which of the following pathways best describe the structures which urine has to flow through before being excreted out of the body? (Hint: some structures may be omitted, so just make sure the general order is correct)
1-Collecting duct -> bladder -> ureter
2-Collecting duct -> ureter -> bladder -> urethra
3-Collecting duct -> urethra -> bladder -> ureter
4-Major calyx -> minor calyx -> renal pelvis -> urethra
Identify the two distinct regions of the kidney and the components of each.explain?

- Urine is not about eliminating water accumulating directly in the urinary bladder. It is instead a very sophisticated process that involves the collaboration of two systems during various phases. Discuss in great detail the urine formation steps.arrow_forwardIngestion of carbonated soft drinks, coffee, and tea instead of water has caused us to be chronically dehydrated. Discuss the impact of this dehydration on overall health and how concentrated urine, indicated by its yellow color, signals the need for more water consumption, while clear and colorless urine indicates that water intake is sufficient.arrow_forwardDescribe how each of the following works to regulate reabsorption and secretion, so as to affect urine volume and composition: renin-angiotensin system, aldosterone and antidiuretic hormone.arrow_forward
- The presence of either protein or glucose in a urinalysis is abnormal, but these two molecules end up in the urine for different reasons. For each of these molecules, briefly describe where in the urine production process (i.e., glomerular filtration, tubular reabsorption or tubular secretion) the problem occurs, and why it might happen.arrow_forwardWhat types of substances tend to be secreted? What types of substances tend to be reabsorbed? Why do we use the term “reabsorption” instead of “absorption” in the kidney? Filtrate is formed by hydrostatic pressure forcing fluid to leave the glomerulus. The filtrate is then collected by the glomerular capsule. List all of the structures, starting with the glomerular capsule, that fluid passes through until it eventually leaves the body. After you have listed the structures, indicate where the fluid is called filtrate, where it’s called tubular fluid, and where it is called urine. glomerular capsule→arrow_forward
