Urinary Tract System includes positions in body, sections of the kidney, and nephrons ins the kidney.
The kidney functions to eliminate metabolic waste, regulate ion levels, regulate pH levels, regulate blood pressure, climate biological molecule elimination, forms calcitriol, produces and releases erythropoietin, and Gluconeogenesis.
The renal medulla and renal cortex function the kidney tissue
Order of blood supple to the kidneys
the intercalated disks regulate urine and pH of blood
each kidney has about million of nephrons.
Each kidney is innervated by both divisions of autonomic nervous system
filtrate includes ==H2O==, ==C6H12O6==, ==A.A==., ==ions==, ==urea==, some ==hormones==, ==Vit. B==, ==Vit. C==, ==ketones==, very small ==protein== amounts
net filtration pressure is the Glomerulus hydrostatic blood pressure. The opposing pressures include Osmotic blood pressure, fluid pressure in capsular space of renal corpuscle.
Glomerular hydrostatic blood pressure (HPg) involves glomerular blood pressure pushing water and some solutes out of glomerulus into capsular space of renal corpuscle which is higher than BP of other systemic capillaries.
Pressures opposing HPg involves OPg and HPc
Net filtration pressure (NFP) is when filtration is greater than opposing pressure
Glomerular filtration rate (GFR) is the rate at which filtrate volume (per unit of time) is formed.
Increase in NFP increases GFR, solutes, h2o, substance in urine, and decreases
Regulation of GFR is tightly regulated and helps kidney control urine production based on physiologic conditions also known as hydration status.
