| | | | | | | | | | | |
blood
-Excretion of metabolic wastes into the urine
| | | | | |
Describe the Drinking Process - CORRECT ANSWER✔✔-Water is
| | | | | | | |
absorbed by the gastrointestinal (GI) tract into the blood, which goes to

| | | | | | | | | |
ANSWER✔✔-They can regulate water volume because they can | | | | | | | |
concentrate or dilute the urine | | | |
Among other things, what are the kidneys responsible for? - CORRECT
| | | | | | | | | | |
ANSWER✔✔-The kidneys are responsible for our ability to survive on | | | | | | | | | |
land without dehydrating

| | | | | | | | | | | |
CORRECT ANSWER✔✔-The Kidneys are located on either side of the .
| | | | | | | | | | |
vertebral column and are partly protected by the ribcage
| | | | | | | |
What are the 2 divisions of the kidney? - CORRECT ANSWER✔✔-The
| | | | | | | | | | |
Renal Cortex and the Renal Medulla
| | | | |
Describe the Renal Cortex - CORRECT ANSWER✔✔-The Renal Cortex is

the outer portion of the kidney
| | | | |
Describe the Renal Medulla - CORRECT ANSWER✔✔-1. inner portion of
| | | | | | | | | |
the kidney
|
2. separated into renal pyramids by renal columns
| | | | | | |
How is blood supplied to the kidneys? - CORRECT ANSWER✔✔-1. Each
| | | | | | | | | | |
Kidney receives blood from a Renal Artery
| | | | | |
2. The Renal Artery Branches into many smaller and smaller arteries
| | | | | | | | | |
3. These smaller arteries travel between renal pyramids within the Renal
| | | | | | | | | |
Columns
|
4. They ultimately deliver the blood via the arterioles to a capillary
| | | | | | | | | | | |
network called the "Glomerulus" | | |
