Functions of urinary system

Transport urine from being made to being stored until release

Electrolyte and fluid balance

Propel urine from kidneys to bladder

Impenetrability to water and small molecules

Accommodate fluctuation of volume of liquid

Tells brain when to release urine

Relaxation and contraction for store/ release of urine"

Absorption

Secretion

protons into filtrate

HCO3-

Collect urine from nephrons

Recovers H2O and sodium chloride form urine

Filter blood and turn filtrate to urine

Structure of Nephron

Renal corpuscle

Glomerular capsule

Proximal convoluted tubule

Nephron loop

Distal convoluted tubule

Ascending limb

Descending limb

Microvilli

Increase surface area and reabsorption capacity

Filtration, reabsorption, secretion

Proximal convoluted tubule

Reabsorption

100% of nutrients and protein

Majority of water

Majority of ions

PO43-

Secretion

Some druge

Nitrogenous waste

Distal convoluted tubule, collecting tubule, collecting duct

Sodium reabsorption

Water reabsorption

Potassium secretion into tubular fluid

Calcium reabsorption

Intercalated cells

Type A secret acid and retain base

Type B secret base and retain acid

Nephron loop and Vasa recta

Continues reabsorption of water and ions

Glomerular Filtration

Passively separates H2O and dissolved solutes from blood plasma (filtrate)

General Info

Osteoporosis

Disease resulting in decreased bone mass

Weakened bones, prone to fracture

More likely in women

Most frequently in wrist, hip, and vertebral column

Estrogen levels

Diabetes Mellitus II

Insulin-independent diabetes mellitus

Decreased insulin release from beta cells

Decreased insulin effectiveness at peripheral tissues

Hypertension

High blood pressure

Can damage blood vessels and lead to cardiovascular disease

Diuretics used

Higher than 140/90

Increasing urine output can lower both blood volume and blood pressure.

Increased urine production and dehydration are symptoms of diabetes mellitus.

Kidneys synthesize the final enzyme in calcitriol formation. Calcitriol increases the absorption of calcium to increase blood calcium concentration. If you have kidney damage this can cause osteoporosis.

Hypertension is a large reason for kidney failure. It can cause arteries around the kidney to narrow, weaken, or harden. Damaged kidneys do not filter blood well which can lead to the blood in her urine. Hypertension can cause increased glomerular permeability.

Damaged kidneys and abnormal hormone levels cause calcium and phosphorus imbalances. Mineral and bone disorders are common with kidney damage because of low glomerular filtration rate.

High levels of glucose with DM can damage millions of filtering units and blood vessels within each kidney. Over time it can cause the vessels to become narrow and clogged. Can cause an abnormal amount of ketones in the urine or increase in other fluid output

The progression to blood in her urine should be evaluated and what is further breaking down in her kidneys to have this happen.

All of these conditions are putting weight on the kidneys functions. The kidney is working over time to try and just keep the patient alive. With little filtration and barely functioning, if this patient does not change her diet, start minimal exercise, and monitor her insulin, her kidney will shut down completely. Her body is not receiving the essential nutrients it needs as well as hormones or ions to keep her blood viscosity and volume at natural levels.
