  • Renal corpuscle

• Renal medulla

  • Majority of the loop of Henle

  • Majority of the Collecting duct

The Juxtaglomerular cells are located around the _____ of the nephron

Afferent arteriole

According to the Renin-Angiotensin-Aldosterone system (RAAS), Angiotensin converting enzyme (ACE) is produced by the _____.

Liver

A _____ is the extension of the renal cortex into the renal medulla found in between the renal pyramids.

Renal column

According to the Renin-Angiotensin-Aldosterone system (RAAS), Renin is produced in the _____.

Liver

Antidiuretic hormone and Aldosterone will act in the _____ of the nephron to retain water.

Collecting duct (as well as the late DCT)

T/F: As the filtrate descends toward the bottom of the loop of Henle, osmolatity decreases.

False.

As the filtrate descends toward the bottom of the loop of Henle, the osmolality increases

T/F: As circulating antidiuretic hormone increases, the individual is likely to produce a concentrated type of urine

True

As circulating antidiuretic hormone (ADH) increases, the body is likely to produce a concentrated type of urin

• (It is without that it becomes diluted)

T/F: The outer region of the kidney, immediately deep to the renal capsule, is called the renal medulla.

False

• It is the renal cortex

Place the structures with their functions

Kidney

• Produces urine

Ureter

• Transports urine to urinary bladder

Urinary bladder

• stores urine

Urethra

• Transports urine out of the body

The _____ produces renin.

Juxtaglomerular cell

T/F: The female urethra is used in both urinary and reproductive purposes.

False

-the female urethra is only used in the urinary system

T/F: The urinary bladder is line with Ciliated pseudostratified columnar epithelium with Goblet cells.

False

• lined with transitional epithelium

The _____ detects osmolatity (concentration of solutes) in the filtrate.

Macula densa cell

The _____ is located at the superior pole of the kidney.

Adrenal gland

Indicate whether the following structures will 'enter' or 'exit' the renal hilum (indentation) of the kidney

Ureter - Exit

Renal artery - Enter

Renal nerve - Enter

Renal vein - Exit

Order in which blood flows into the kidney

1. Renal arterty

2. Interlobar artery

3. Arcuate artery

4. Cordical radiate artery

5. Afferent artery

6. Glomerulus

7. Efferent artery

8. Peritubular capillaries

9. Vasa Recta

10. Cortical radiate vein

Microscopic processes of the nephron

Tubular reabsorption: Fluid and solutes movement from the renal tubular strutures to the peritubular capillaries

Tubular secretion: Fluid and solutes movement from the peritubular capillaries to the renal tubular strutures

Filtration: Fluid and solutes movements from the Glomerulus and the Bowman's capsule

The nephron in order in which filtrate flows through.

• 1st: Renal corpuscle

• 2nd: Proximal convoluted tubule

• 3rd: Descending loop of Henle (Thick)

• 4th: Descending loop of Henle (Thin)

• 5th: Ascending loop of Henle (Thin)

• 6th: Ascending loop of Henle (Thick)

• 7th: Distal convoluted tubule

• 8th: Collecting duct
