2
Q
What is the main functions of the kidneys?
A
- excretes toxins like urea
- manages water content of the blood
- manages ion (salt) content of the blood
3
Q

A
- bladder
7
Q
What are the eight structures of the kidney?
A
- Medulla (pyramids)
- Capsule
- Minor calyx
- Cortex
- Renal artery
- Renal vein
- Renal pelvis
- Ureter
8
Q
What is the medulla?
A
- inner region made of loops of Henle, collecting ducts and blood vessels
9
Q
What is the capsule and its function?
A
- fibrous outer membrane for protection
10
Q
What is the minor and major calyx? *not exam spec for context
A
- the extensions leading to the ureter
- major is multiple of them
11
Q
What is the cortex?
A
- outer region made of renal (Bowman’s) capsules, convoluted tubules and blood vessels
12
Q
What is the papilla of the medulla? *not exam spec for context
A
- inner regions of medulla connecting to the minor calyx
13
Q
What does the renal pelvis do?
A
- collects urine
14
Q
How is urea formed?
A
- from excess amino acids and process of deamination breaks down to form urea
15
Q
What are nephrons?
A
- Tubular structures in each kidney form the basic structural and functional units of the kidney
16

A
- Bowman’s capsule
- glomerulus
- Renal artery
- Afferent arteriole
- Efferent arteriole
- Proximal convoluted tubule
- Distal convoluted tubule
- Collecting duct
- Loop of henle (descending limb)
- Loop of henle (ascending limb)
