Introduction:: The purpose of the urinary system is to eliminate cellular waste from the body, regulate blood volume and blood pressure, maintain our body water balance, control levels of electrolytes and metabolites, and regulate blood pH. Since all the fluids of the body are interrelated (blood, lymph, interstitial fluid, etc.), it is essential for our urinary system to regulate the overall fluid levels in our bodies.
For this post, you will:
Choose a component or process of the urinary system that helps to regulate the amount of water that is excreted in the urine. Some examples are:
renal vessels and nerves
intrarenal blood pressures
glomerular pressure
glomerular filtration
reabsorption in the proximal tubule
reabsorption in the loop of Henle
reabsorption in the (late) distal convoluted tubule
vasa recta (rather than peritubular capillaries
cortical vs. juxtamedullary nephron
collecting duct
aquaporins
juxtaglomerular complex
role of hormones (e.g., ADH, Aldosterone, renin/angiotensin II
Describe how your choice can be used in either retention or loss of water in urine. Choose only retention or loss, not both.
Use a reputable media article or scientific journal paper to describe a water imbalance (too much or too little water retention) that affects health.
Describe the treatment and management of your selected water imbalance.
