Study Notes
Urinary System Functions
- The main function of the urinary system is to filter waste and excess fluids from the blood.
Urinary System Structure
- The urinary system includes kidneys, ureters, urinary bladder, and urethra.
- The structures NOT included in the urinary system are the adrenal glands.
Ureters
- Ureters are muscular tubes that transport urine from the kidneys to the bladder.
- They are located retroperitoneally, surrounded by a layer of fibrous connective tissue.
Osmotic Gradient Formation
- The medullary osmotic gradient is formed by the countercurrent multiplier system in the loop of Henle.
- This gradient enables the kidneys to concentrate or dilute urine.
Blood pH
- The normal pH of blood is slightly alkaline, ranging from 7.35 to 7.45.
Accessory Digestive Organs
- The liver, gallbladder, and pancreas are considered accessory digestive organs.
Mucosal Barrier Function
- The mucosal barrier in the stomach protects the stomach lining from acidic digestive enzymes.
Hormone Regulation
- The hypothalamus releases antidiuretic hormone (ADH), which regulates water reabsorption in the kidneys.
- Aldosterone is responsible for increasing the reabsorption of sodium and water in the kidneys.
Glomerular Filtration
- Glomerular filtration is the process by which water and solutes move from the glomerulus into the Bowman's capsule.
Renal Tubules
- The process of reabsorption and secretion of substances in the renal tubules is called tubular reabsorption and secretion.
- The proximal tubule is responsible for reabsorbing glucose, amino acids, and other essential nutrients.
Urine Concentration
- The process of increasing the concentration of urine is called hypertonic reabsorption.
Urine Characteristics
- Urine is normally clear, yellowish in color, with a pH range of 4.5 to 8.
- Glucose is not normally present in urine, but its presence is a characteristic of diabetes mellitus.
Micturition
- The process of emptying the bladder is called micturition.
Urinary System Regulation
- The macula densa and granular cells in the Juxtaglomerular Apparatus (JGA) regulate blood pressure and electrolyte balance.
Nephron Structure
- There are two types of nephrons in the kidney: cortical nephrons and juxtamedullary nephrons.
- The glomerulus is a cluster of capillaries surrounded by Bowman's capsule, which filters the blood.
- The glomerulus and renal corpuscle are not the same structure; the renal corpuscle includes the glomerulus and Bowman's capsule.
Nephron Function
- The proximal tubule reabsorbs glucose, amino acids, and other essential nutrients.
- Tubular secretion is the process of removing substances from the blood and adding them to the filtrate in the renal tubules.
- The main force that promotes glomerular filtration is the hydrostatic pressure in the glomerular capillaries.
- The majority of water reabsorption occurs in the proximal tubule and the loop of Henle.
- The urethra is responsible for transporting urine from the bladder to the outside of the body.
