Kidney function Flashcards
Two main parts of the kidney
Renal cortex
Renal medulla
Parts of the nephron
Glomerulus
Tubules
Which is the functional part of the kidney?
The nephron
Acronym AEIOU
Acidosis Electrolytes Intoxication Overload Uremia
What is the glomerulus?
A ball of capillaries in a sac called Bowman’s Capsule.
Parts of the tubular system
- Proximal convoluted tubule
- Loop of Henle
- Distal convoluted tubule
- Collecting tubule
Functions of the kidney in maintaining homeostasis
- Remove water and waste
- Maintain electrolyte balance
- Control BP
- Make hormones
- Maintain pH
Hormones/enzymes made by kidneys
- Erythropoietin
- Calcitriol
- Renin
What does erythropoietin do?
Tells bone marrow to make RBCs
What does calcitriol do?
Allow gut to absorb calcium from food
What does renin do?
Helps control BP
Seven major electrolytes
- Sodium
- Chloride
- Calcium
- Bicarb
- Magnesium
- Phosphate
- Potassium
Two ways kidneys control BP
- Retain or release water
2. Use renin to form angiotensin, which holds onto salt and water and constricts vessels
Symptoms of metabolic acidosis
- Weakness & fatigue
- Rapid breathing
- Racing heartbeat
- Headache
- Confusion
Types of kidney failure
- Acute Kidney Failure (AKI)
2. Chronic Kidney Disease
