GFR is influenced by the hydrostatic pressure and colloid osmotic pressure on either side of the capillary membrane of the glomerulus. This important process provides a mechanism for the body to get rid of metabolic wastes and toxins, which can be deadly if allowed to accumulate in the body. The bladder is a muscular chamber that expands as urine fills it. After the urine enters the bladder from the ureters, small folds in the bladder mucosa act like valves preventing backward flow of the urine. PhD Lecture-1 Introduction 31/3/2015 1.

Body Fluids and Fluid Compartments. Blood at high pressure travels into these tubules by the tuft of blood capillaries called glomerulus. Urine characteristics change depending on water intake, exercise, environmental temperature, and nutrient intake. • There are two distinct areas of muscle: the internal sphincter, at the bladder neck and • the external, or distal, sphincter. At about 200 ml of urine, the detrusor muscle begins to contract and the internal urethral sphincter muscle begins to relax. They can excrete urine with an osmolarity as low as 50 mOsm/L, when there is excess water in the body and ECF osmolarity low. Yanal A Shafagoj. Nephronic tubules drain in collecting duct. Regulation.
