NSG 3315 Lecture Notes - Lecture 7: Coronary Sinus, Water Balance, Hyperaldosteronism
Document Summary
Homeostasis depends on maintaining a balance between input and output of all parts of internal environment. Control of ecf osmolality - solute within ecf. Percentage of total body uids vary with age and amount of body fat. Water moves between icf and ecf by osmosis remember that water will follow the area with more articles or solute (proteins) Water imbalances occur when there is an excess or depletion of body uids. Water moves due to changes in pressures at the capillary level. Outward force - interstitial and capillary hydrostatic pressure pushes water against each other. The movement of water through a selectively permeable membrane toward an area of greater solute concentration. The measurement of the concentration of solutes per kilogram of. Number of osmoses of solute per liter of solution. Major solutes are sodium, albumin, potassium, and magnesium. Movement of water out of capillary and into interstitial spaces. Capillary hydrostatic and interstitial osmotic pressure works in ltrations favor.
