Smart Edition Urinary Flashcards
The nephron consists of 2 parts
Renal corpuscle & renal tubule
The renal Corpuscle can be divided into 2 areas
Glomerulus
Glomerular capsule
Surrounding the glomerulus is the ….
Bowmans capsule
Which part of the Nephron filters
Glomerulus
Which part of the Nephron is involved in reabsorption and secretion
Tubule
The renal tubule can be divided into 4 parts name them
Proximal Convoluted Tubule
Loop of Henle
Distal Convoluted Tubule
Collecting duct
Waste elimination, Osmoregulation of blood and water, Hormone Secretion ( ADH) are what
The function of the urinary system
Kidneys turn ______ into a hormone (calcitriol) which helps increase calcium absorption from the intestines into the blood
Vitamin D
Vitamin D and ________ help regulate how much calcium is absorbed and how much the kidneys need to eliminate
(PTH) Parathyroid Hormone
Which are the sites of reabsorption in the Nephron. Which is the major site
Proximal tubule (major site of reabsorption)
Loop of henley
Distal Convoluted tubule
Tubular secretion takes place in this part
Pct & dct
In which part of the Nephron is urine created
Collecting Duct
The urinary system returns important substances back to the blood stream during…
Tubular reabsorption
Where is ADH secreted from
Posterior pituitary gland
One of the most important functions of ADH is to regulate urine concentration and volume by controlling how much water is reabsored in the ______ of the nephrons
Tubules
Antidiuretic hormone primarily controls tubular reabsorption of which substance
Water
Blood enters kidney through renal artery
Blood flows into glomerulus
Water / Solutes diffuse into the tubule
Filtered fluid flows toward the proximal tubule for reabsorption if solutes and ions
Next loop of henley
What is the last step
Urine is collected in the collecting ducts before excretion
_______________ is the transfer of materials from peritubular capillaries to the renal tubular lumen; it is the opposite process of reabsorption.
Tubular secretion
____________ is the process that moves solutes and water out of the filtrate and back into your bloodstream.
Tubular reabsorption
