4 functions of Urinary system
Helps regulate BP
Acid-base balance
Homeostatsis of fluid volume
Filters blood, excretes waste
Macroscopic structures of kidney
Kidney is bean shaped
Located in Retroperitoneal space
Held in place by Gerotas capsule
Protected by fat and renal capsule
2 sections Renal Cortex and Renal Medulla
Microscopic structures of kidney
located at border
Nephrons - Bowmans and Glomerulus
Calyces
Renal Spaces
Ducts for routing urine
Renal Pelvis
4 layers of Urters
Muscosa - Mucous Layer
Submucosa - Vsacular Layer
Muscularis - Smooth Muscle Layer
Serous - Parietal Peritoneum
4 layers of Urinary Bladder
Muscosa - Muscous Layer
Submucosa - Vascular layer
Detrusor - Smoothe Muscle Layer
Serous - Parietal Peritoneum
What layer does Peristalsis occur
Muscularis/Detrusor
Male Urethra
8 in long
Below prostate gland
Runs thru prostate
Easier to control
Female Urethra
1 1/2 - 2 in long
Embedded in vagina
Near opening of the meatus
Harder to control
Normal pathway of urine
Artery to Cortex
Nephron
Renal Medulla
Calyces
Tubules
Sinuses
Renal Pelvis
Ureter
Bladder
Urinary Sphincter
Urethera
Urinary Meatus
Normal Constituents of urine
Urea
Creatine Salts
Hydrogen Ion
Uric Acid
Pigments
Meatbolic Wastes
Normal Bacteria
Nicitric Acid
Hormones
Toxins
Abnormal Constituents of urine
RBC
WBC
Albumin
Pus
Too much bacteria
Glucose
Micturition
Urination
Excretory Systems
Respitory - Lungs
Integumentary - Skin
Digestive - GI Tract
Urinary - Urine
Renal Capsule
Protective fibrous layer surrounding the kidney
Renal Cortex
Outter portion of kidney
Renal Medulla
Inner portion of Kidney, 2 parts
Renal Pyramid
Triangler divisions of medulla of kidney
Renal Papilla
Narrow, innermost part of renal pyramid
Minor Calyx
A division of the renal pelvis
Renal Artery
Brings blood to kidney, 20% of blood pumped by heart goes to kidney for filteration by aorta
Renal Vein
Return of blood back to the heart by Verna Cava
Renal Pelvis
Basin like upper end of the ureter located in the kidney
Ureter
Tubes that carries urine from the kidney to bladder
Genral function of Digestive system
Digestion/breakdown of macroscopic food, or microscopic nutrients for cells
Enzyme
Protein that acts as a catalyst for cellur process
Absorption
Intake of substance through membranes
Digestion
Breakdown of foods to simple molecules
Peritoneum
Serous membrane that lines abdominal pelvic cavity. Largest in the body
Omentum
Fold of peritoneum and fat
Mesentery
Fold of peritoneum that attachs organs to posterior wall
Web-like
Brings blood and lymph fluids to organs
Bolus
Soft chewed mass ready to be swallowed
Sphincter
Circular muscle that closes off tubular structure
Chyme
Partially digested food and chemicals in the stomach/intestine
Rugae
Fold of mucosa for stretchability
Peristalsis
Wave like motion of smooth muscle
