Urinary System Flashcards
1
Q
Functions of the uninary system (5)
A
- Excretion of waste products that are created when food is transformed into energy (metabolism).
- Maintains the correct balance of water and electrolytes (salts) within the body.
- Regulates blood pressure and sodium re-absorption.
- Regulates the production of blood cells and platelets.
- The metabolism of vitamin D (by converting it into an active hormone)
2
Q
Uninary system components (4)
A
- Kidneys
- Ureters (tubes that connect the kidneys to the bladder)
- Bladder
- Urethra (the tube through which urine exits the body).
3
Q
Urinary system process (6)
A
- Blood Stream
- Kidneys
- Ureters
- Bladder
- Urethra
- Out of Body
4
Q
nephron definition
A
A tiny filtering system in the kidney
5
Q
Parts of a nephron (2)
A
- renal corpuscle
- renal tubule
6
Q
glomerulus function
A
- filters blood
7
Q
Proximal tubule function
A
- returns needed substances to your blood and removes wastes
8
Q
Bowman’s capsule function
A
- cradles the glomerulus
9
Q
Nephron filtering process (9)
A
- Blood
- Filters through Glomerulus (in the Bowman’s capsule)
- Filtrate moves through Proximal Tubule
- Loop of Henle
- Distal Tubule
- Collecting Duct
- Ureter
- Bladder
- Urethra
10
Q
Parts of the renal corpuscle (2)
A
- glomerulus
- bowman’s capsule
11
Q
Renal Tubule parts
A
- proximal tubule (proximal convoluted tubule)
- loop of henle
- distal tubule
12
Q
proximal tubule reabsorbs..?
A
Glucose
13
Q
What is reabsorbed in loop of henle? (2)
A
- Various ions
- some water molecules
14
Q
The distal tubule controls..?
A
The PH of the blood
15
Q
Where is water reabsorbed into the blood stream?
A
from the filtrate in the collecting duct
