Q

Kidneys perform this function through multiple processes.

A
  1. Excretion
    2.Regulation of Blood Volume and Pressure
  2. Regulation of Extracellular fluid pH
  3. Regulation of RBC synthesis
  4. Regulation of Vit D Synthesis
  5. Regulation of the Concentration of Solutes in the Blood

Q

Functional units of the kidney

A

Nephrons

18
Q

Three Categories of Urine Production

A
  1. Filtration
  2. Tubular Reabsorption
  3. Tubular Secretion
19
Q

Chemicals that increase the rate of urine formation

A

Diuretics

20
Q

Under diuretics which increases renal blood flow and the rate of glomerular filtrate formation.

A

Caffeine

21
Q

Small tubes that carry urine from the renal pelvis of the kidney to the posterior inferior portion of the urinary bladder.

A

Ureters

22
Q

A hollow, muscular container that lies in the pelvic cavity just posterior to the pubic symphysis. It stores urine

A

Urinary Bladder

23
Q

Tube that carries urine from the urinary bladder to the outside of the body.

A

Urethra

24
Q

Triangle-shaped portion of the urinary bladder.

A

Trigone

25
Q

A junction between bladder and urethra. It contracts to keep semen from entering the bladder during sex.

A

Internal Urinary Sphincter

26
Q

Skeletal muscle that surrounds urethra which allows a person to start or stop flow of urine through urethra.

A

External Urinary Sphincter

27
Q

Two major body fluid compartments

A
  1. Intracellular Fluid Compartment
  2. Extracellular Fluid Compartment
28
Q

Includes the fluid inside all the cells of the body

A

Intracellular Fluid Compartment

29
Q

Includes all the fluid outside the cells

A

Extracellular Fluid Compartment

30
Q

High blood pressure at the arterial end of a capillary pushes fluid out of the capillary and into the interstitial space surrounding cells.

A

Filtration

31
Q

Fluid is pulled back into he capillary from the interstitial space.

A

Reabsorption.

32
Q

Occurs when the body’s pH falls below 7.35

A

Acidosis

33
Q

Body’s pH rises above 7.45

A

Alkalosis
