What will I learn?
Gain a practical grasp of body fluid compartments, osmolarity, and homeostasis under exercise and heat stress. Delve into sweating mechanisms, cardiovascular and respiratory adaptations, renal regulation, ADH, aldosterone, thirst mechanisms, and feedback systems. Apply this to confidently analyze lab results and forecast fluid-electrolyte shifts.
Elevify advantages
Develop skills
- Analyze fluid compartments: interpret ICF, ECF, and plasma volume shifts rapidly.
- Predict hormone responses: forecast ADH, aldosterone, and thirst under physiological stress.
- Interpret renal data swiftly: connect GFR, urine osmolarity, and output to dehydration states.
- Confidently read lab indicators: hematocrit, plasma osmolality, specific gravity.
- Map integrated feedback loops: combine neural, renal, and hormonal homeostasis controls.
