Study Notes
Excretory System Functions
- The excretory system performs vital functions beyond blood purification and waste removal, including pH control, erythropoietin production, and vitamin D synthesis.
- pH control is a shared function between the lungs and blood buffers, maintaining blood pH between 7.35 and 7.45 to prevent death.
- The kidneys produce 85% of erythropoietin (EPO) necessary for red blood cell formation.
Kidney Functions
- The kidneys undertake the final synthesis step in the creation of vitamin D.
- The kidneys act as a plasma regulator, maintaining equilibrium and influencing overall quality of life.
Consequences of Kidney Failure
- Kidney failure disrupts homeostasis, leading to symptoms such as weakness, fatigue, shortness of breath, anemia, generalized edema, metabolic acidosis, increased potassium levels, and heart arrhythmias.
- Each of these functions is critical to survival and well-being, and their disruption can have severe consequences.
