Urogenital Histology and intro Flashcards
1
Q
Liver basic function
A
Adjusts the nutrient concentration in cicrculating blood
2
Q
Digestive system basic function
A
Absorbs nutrients from food and excretes waste
3
Q
Urinary System 3 functions
A
- Excretion
- Removal of organic waste from body fluid
- Elimination
- Homeostatic regulation
- Of blood plasma volume and solute conctration
4
Q
What are the 5 main Homeostatic functions of urinary system
A
- Regulate blood volume and pressure
- Regulate plasma ion concentrations
- Helps stabilize blood pH
- Conserves valuable nutrients
- Assists liver
5
Q
Regulation of blood volume and pressure
A
- Adjusts volume of water lost in urine
- Releases erythropoietin and renin
6
Q
Regulation of plasma ion concentrations
A
- Controlling amount lost in urine of sodium, potassium and chloride
- Calcium ion levels through calcitriol synthesis
7
Q
Stabilize blood pH
A
Controlling loss of hydrogen and bicarbonate ions in urine
8
Q
Kidney Location
A
- Located on either side of vertebral column
- Left kidney is higher than right
- Adrenal glands lay on top
9
Q
Kidney position is maintained by
A
- Overlying peritoneum
- Contact with adjacent visceral organs
- Supporting connective tissue
10
Q
What are the 3 layers that protect the kidney
A
- 3 concentric layers of connective tissue
- Fibrous capsule (touching organ)
- Perinephric fat capsule
- Renal fascia
11
Q
Fibrous capsule
A
- Layer of collagen fibers
- covers outer surface of entire organ
12
Q
Perinephric fat capsule
A
- Thick layer of adipose
- Surrounds renal capsule
13
Q
Renal fascia
A
- Dense, fibrous outer layer
- Anchors kidney to surrounding structures
14
Q
Nephrons
A
- Mcroscopic tubular structures in cortex of each renal lobe
- Where urine production begins
15
Q
Blood supply to kidneys
A
- Kidneys receive 25 % of total cardiac output
- 1200 ml blood flows through kidney each min
- Kidney received blood through renal artery
