Question
Relaxed urinary bladder Compare the epithelium of the relaxed and distended urinary bladder. What difference do you notice? MAKE THE CONNECTION Why, when a surgeon is operating on the kidney, is the surgery performed from the side/posterior part of the abdomen and not through the anterior abdominal wall? 1. Kidney stones are usually located in the renal pelvis. What affect would this have on urine flow and contents? Why are they so painful? 2. What is the most common composition of kidney stone? 3. Imagine that you had two large cups of coffee before you left for work. Now you are on the highway, there is an accident ahead, and you have been sitting in traffic in your car for two hours. What is the condition of the rugae in your urinary bladder? After urine is produced and stored in the urinary bladder, it is not reabsorbed into the body. What prevents the reabsorption? 125Explanation / Answer
Ans 1...the anatomical postion of kidney is posterior.it is a retro peritonial organ that lies behind the peritoneum and close to the posterior abdomen wall that's why it's surgery is performed from posterior side
Ans 2.....renal stones in renal pelvis obstruct the flow of urine from kidney.it leads to decrease urine output
Renal stones obstruction causes back pressure in kidney which leads to hydronephrosis.moreover it irritates the nerves that's why are very painful
Most common composition of kidney stone is calcium oxalate.
Ans 3...Rugae are the mucosal folds seen when the bladder is empty.when bladder fills it expands and Rugae fills and disapperar.so in given condition in ques the urinary bladder must have distended in 2 hours and filled up thus the Rugae would have less prominence now.
The urinary bladder is lined by transitional epithelium also known as umbrella cells which is impermeable and doesnt allow passage of fluid from urinary bladder into body.
