Renal system L15 Flashcards
What are the sources of water in the body?
drinking, food, metabolism
What are the routes where the water can exit the body
Lungs, Skin, Poo, Urine
what fluid compartments are there
Plasma, interstitial, ECF, Fat, Intracellular, Transcellular
What is plasma?
A fluid compartment of the blood, occupying 55% of the blood.
What is Haematocrit
A measure of amount of blood occupied by cells
How to work out of volume of distribution in a given fluid
Vd= Q(amount of drug)/ Cp(Plasma conc of drug)
what is osmotic pressure and what is the interface regarding the biological tissues.
Osmotic pressure is the inverse of osmosis where it opposes the water movement.
Role of Kidney
-excreting useless and toxic compounds
-maintaining homeostasis, pH, Volume
-
Role of urinary tract (lower)
- stores urine
What is the interaction with GIT system and Renal systems
- acheiveing EQB between the inputs from the GIT and the outputs from the kidneys
What is the interaction with CVRS and Renal systems
- maintaining BP through regulating Volume of fluid
- ## regulating ionic composition for cardiac muscle function
What is the interaction with RS and Renal systems
regulating pH otherwise it can lead to metabolic acidosis and alkalosis
-joint pathways for renin-angiotensin
What is the interaction with endocrine system and Renal systems
- regulating aldosterone for renal Na+ and water reabsorption
- regulates release ADH
- regulates Vit D
What is the interaction with ANS and Renal systems
- kidneys receives afferent innervation to control blood flow in the kidney
What is the interaction with Haematology and Renal systems
- kidneys regulates production of RBCs
