W4 D1 - Renal A&P Flashcards
What are the functions of the kidney?
Excretory
* water
* electrolytes
* metabolic wastes: urea, uric acid, creatinine, bilirubin
* chemicals: drugs, pesticides, additives
Regulatory
* electrolytes
* acid/base pH of blood
* extracellular fluid volume
* blood pressure
* glucose metabolism
Hormone production
*
Explain the anatomy of urine formation
* the cortex, medulla, and collecting ducts
Cortex
Medulla
Collecting ducts
What are the components of the nephron?
Explaining the anatomy of the collecting
Minor & major calyx
Renal Pelvis
Ureter
Bladder
Explain the flow from Bowman’s capsule to the urinary meatus
What is afferent and efferent arteriole?
Explain the flow of blood from the heart to the kidney and heart
What is glomerular filtration?
What is tubular reabsorption?
What is tubular secretion?
What are the roles of ADH, aldosterone, parathormone, vitamin D?
Roles of ADH
Aldosterone
Parathormone
Vitamin D
Explain urinary formation
In order:
1. Filtration of plasma into Bowmans capsule: houses the glomerulus
2. Proximal convoluted tubules: reabsorption
3. Loop of Henle: concentration of urine
4.Distal convoluted tubule: reabsorption of water, Na & K w/ ADH
5. Collecting ducts:
Explain the concentration of water
What is the juxtaglomerular apparatus?
Connects afferent arteriole and distal tubule ?
Regulates BP by releasing renin
Macula densa - detect sodium levels and releases renin to
Discuss water regulation step by step
