Part 1

Question 1

What are the functions of the Kidney?

Answer 1

Regulate extracellular fluid
Produce urine - concentration of waste products
concentration of electrolytes
Balance blood ph
Balance water in body

Question 2

The transfer of products in the urinary system..

Answer 2

Blood from aorta, the renal artery carries this to the kidney. The kidney filters out the blood carrying the waste product to the ureter. From the ureter it goes to the bladder where it is hold until excreted. When waste product is ready to leave, it goes to the urethra.

Question 3

Looking at a picture of a kidney, what is the
Outer layer:
Inner layer:
function of the Renal pelvis:

Answer 3

Outer layer: is the Renal Cortex
Inner layer: is the Renal Medulla
Function of the Renal Pelvis: Is a hollowed area that connects with the ureter. It collects urine and transport it to the ureter

Question 4

What is the Kidney’s function unit?

Answer 4

the NEPHRON

Question 5

1. What is the capillary network (not glomerulus)?

Answer 5

Blood vessels that surrounds the Nephron

Question 6

2. What is the afferent arteriole?

Answer 6

The renal artery carries blood to kidney and blood enters the glomerulus through the arteriole. It is located in the cortex

Question 7

3. What is the Efferent arteriole?

Answer 7

Carries blood out of the glomerulus. Located in the cortex

Question 8

4. What is the the glomerulus and function?

Answer 8

The glomerulus is a high pressure capillary that filters the blood. it is surrounded by the Bowman’s capsule. Located in the cortex

Question 9

5. What is the Bowman’s capsule and function?

Answer 9

The bowman’s capsule creates urine from filtrate of blood from glomerulus. It create this under high pressure. located in cortex

Question 10

6. What is the proximal tubule?

Answer 10

It is a section of the nephron that joins the Bowman’s capsule with the loop of Henle. It is located in the cortex

Question 11

7. What is the loop of Henle?

Answer 11

the loop of Henle joins the proximal tubule to the distal tubule. It decends to the medulla but then back to the cortex where the distal tubule is located.

Question 12

8. what is the distal tubule?

Answer 12

The distal tubule carries the urine from the loop of Henle, to the collecting ducts. It is located in the Cortex

Question 13

9. What are collecting ducts?

Answer 13

Collecting ducts carries the urine obtained from the distal tubule carrying it to the renal pelvis. There are many nephrons in our kidneys that transport urine from collecting ducts to renal pelvis. This site is merge from Cortex to Medulla in the kidney.
