|
angiotensin II functions |
Vasoconstricter: raises TPR Stimulate adenal cortex to secrete aldosterone |
|
|
justaglomerular cells function |
secrete renin (regulates R, ALDO, ANGIO II cycle) and it does this wehn there is a fall inblod pressure. It also reduces unrine volume to conserve fluid |
|
|
Macula densa cells |
have large concentration of mitrochondria. Ion channels are sensitive to NaCl in lumen of distal convoluted tube Signal for smooth muscle to change its resistance |
|
|
Lacis cells |
between macula densa and smooth muscle of afferent ateriole. Coupled to each other by gap junctions |
|
|
Jutagolumurler cells secrete rnin in response to ___________ nerve stimulatoin |
sympathetic |
|
|
Hypovolemic chock can occur in the foloowing conditions |
-hemorrhage -dyhydration -slat deprivation -vomitiiing -diarrhoea -extensive buring -loss of blood serum or plasma (crushing injuries) |
|
|
Aldosterone function |
Stimulate kidney to absorb sodium and water |
|
|
plasma potasium conc. decreases |
-less secretion of aldosterone by Adrenal cortex -more sodium excretion -less potassium excretoin |
|
|
extracellular water descriptoin |
Around out bodies cells has salts one quarter plasma |
|
|
hypocalcemia |
caused by hypoparathyroidsim and vit. D deficieny Can have twitching muscle framps tetany, seizure, cardiac syrhythmsia |
|
|
hyperclacemia |
hyper-parathyroidsim, adenoma, vit. D overdose, letharygy, nausea, coma, constipation |
|
|
plasma ph formula |
6.1 + log(HCO3-/0.03*PCO3) |
|
|
Kidney water reabsorbtion formula |
Excreted = (Filtered + Secreted) - Reabsorbed |
