What will I learn?
This course provides a practical grasp of body fluid compartments, osmolarity, and homeostasis under intense exercise and heat stress. Learners will study sweating mechanisms, cardiovascular and respiratory adaptations, renal regulation, ADH, aldosterone, thirst mechanisms, and feedback systems, then use this to confidently analyze lab results and forecast fluid and electrolyte shifts.
Elevify advantages
Develop skills
- Analyze body fluid compartments by interpreting shifts in ICF, ECF, and plasma volumes swiftly.
- Predict hormonal responses including changes in ADH, aldosterone, and thirst during physiological stress.
- Interpret renal data rapidly by connecting GFR, urine osmolarity, and volume to states of dehydration.
- Confidently read lab indicators such as hematocrit, plasma osmolality, and urine specific gravity.
- Map out feedback loops integrating neural, renal, and hormonal mechanisms for homeostasis control.
