Does normal saline affect the plasma osmolarity?
no
The cells of the distal convoluted tubule which monitor changes in urine volume and osmolarity are called what?
macula densa
What is the volume of 125 deciliters expressed in milliliters?
a hospital has 125 deciliters bags of plasma. what is the volume of plasma expressed in milliliters
Which phases has a variable volume?
The gas and plasma phases have a variable volume.
Does water flow from Low Osmolarity to High Osmolarity?
yes, water flows from low osmolarity to high osmolarity when two solutiona are separated by a semi-permeable membrane till the solutions on either side of the membrane attains equal osmolarity.
What triggers ADH?
the high osmolarity of blood acts upon the osmoreceptor of hypothalmus cause the release of adh low plasma volume increase plasma cholecystokinin
What causes vasopressin increase?
yea,by retention water ,it increase blood volume,which ultimately increase blood pressure..
Does normal saline affect the plasma osmolarity?
no
Connection between plasma osmolarity and total body water in mathematical equation terms?
Plasma Osmolarity =Total Body mOsm - Urine mOs-------------------------------------Total Body Water - Urine Volumeand: Total Body Osmolarity = PLasma Osmolarity x Weight x 0.6 Total Body Water = Weigth x 0.6
Does 0.9 percent normal saline affect plasma osmolarity?
no
Which is the major stimulus for the thirst mechanism?
increased osmolarity of blood plasma
Does plasma have no define volume?
Plasma hasn't a definite volume.
What factors stimulate an increase in ADH secrection?
ADH secretion is stimulated by increase in plasma osmolarity. Example:ingestion of Na+ will cause the plasma osmolarity to increase and trigger the pituitary gland to produce ADH.
Will water intake effect human blood volume?
For the short term and with reasonable amounts of water, ingested water will increase blood volume only transiently. However if there is kidney or cardiac problems or in cases where massive amounts of water is ingested the increase in volume plus the decrease in osmolarity of the blood is fatal.
The cells of the distal convoluted tubule which monitor changes in urine volume and osmolarity are called what?
macula densa
Does plasma have volume?
Yes.
Does plasma have definite volume?
no.
