what is the average length of the female urethra?
1.5 inches
why are urinary tract infections more common in females?
because the female urethra is shorter
what is the capacity of a healthy adult bladder?
300-500 mL
what does ADH do?
increases water reabsorption in kidneys and reduces urine output
when is ADH released?
when dehydrated, when low blood volume, and when there’s high blood osmolarity
what is the result of ADH?
more water stays in the blood and blood pressure increases
what does aldosterone do?
reabsorbs sodium in kidneys and water follows sodium
what is the result of aldosterone?
increased blood volume and pressure
what is the renin-angiotensin-aldosterone system (RAAS) triggered by?
low blood pressure and volume
what are the effects of the renin-angiotensin-aldosterone system (RAAS)?
vasoconstriction (angiotensin II), aldosterone release, ADH release, and increased thirst
what is the functional unit of the kidney?
the nephron
how many nephrons does each kidney have?
1 million
what is the flow of filtrate through the nephron?
glomerulus > bowman’s capsule > proximal convoluted tubule > loop of henle (descending then ascending) > distal convoluted tubule > collecting duct
which part of the nephron filters small molecules out of the blood?
glomerulus
which part of the nephron collects filtrate, blocks larger molecules, and sends filtrate to the tubule system?
bowman’s capsule
which part of the nephron reabsorbs ions, water, and nutrients and removes toxins and adjusts filtrate pH?
proximal convoluted tubule
which part of the nephron is highly permeable to water but impermeable to solutes and water is drawn out via osmosis which concentrates the filtrate?
descending loop of henle
which part of the nephron is impermeable to water but permeable to ions and reabsorbs Na+ and Cl- from the filtrate into interstitial fluid?
ascending loop of henle
which part of the nephron fine tunes sodium, potassium, and pH balance and also responds strongly to aldosterone?
distal convoluted tubule
which part of the nephron determines final urine concentration and includes final water reabsorption (controlled by ADH)?
collecting duct
