EXAM QUESTIONS
QUESTION 1
How long is the urethrae in females ?
CORRECT ANSWER
3 cm long
-meatus is in the vestibule
RATIONALE: The question is referring to the urethra in females, which is actually a short passage called the urethral
meatus, and its length in the vestibule of the vulva is typically around 3-4 cm, but 3 cm is a commonly accepted average
measurement. The key concept here is that the urethral meatus is a distinct structure from the urethra itself, and its length
is measured in the context of the vestibule, rather than the entire urethral length.

, QUESTION 2
renal corpuscle
CORRECT ANSWER
glomerulus and glomerular capsule
RATIONALE: The renal corpuscle is the functional unit of the nephron where blood filtration occurs, and it is composed of
two distinct parts that work together to facilitate this process: the glomerulus, a cluster of capillaries, and the glomerular
capsule, a Bowman's capsule that surrounds it. The combination of these two structures allows for the complex filtration
process that is essential to the kidney's role in removing waste and excess substances from the blood.
QUESTION 3
the outside layer in a kidney is the ___________
CORRECT ANSWER
cortex
RATIONALE: The outside layer in a kidney is called the cortex because it refers to the outermost layer of a multi-layered
structure, such as a kidney, where most of the filtration and nephron cells are located, which are essential for the kidney's
function. The term "cortex" is derived from the Latin word for "bark," implying the outer layer of an organ, similar to the
bark of a tree, making it a fitting description for the kidney's outer layer.
QUESTION 4
fluid and electrolyte balance
CORRECT ANSWER
implies homeostasis
RATIONALE: Fluid and electrolyte balance is crucial for maintaining proper cellular function and overall body equilibrium,
and homeostasis is the physiological process that regulates and maintains this balance through various mechanisms such as
osmoregulation and electrolyte transport. In essence, homeostasis implies fluid and electrolyte balance by dynamically
adapting to changes in the body's internal environment to ensure optimal fluid and electrolyte distribution, concentration,
and availability.
QUESTION 5
Urinary system
CORRECT ANSWER
funnnn..
RATIONALE: The answer "funnnn.." is a play on the word "funnel", which is a key concept in the urinary system as it
relates to the ureters, which are narrow tubes that funnel urine from the kidneys to the bladder. This analogy highlights the
idea of a narrow passage through which urine flows, illustrating the function of the ureters in the urinary system.

, QUESTION 6
Function
CORRECT ANSWER
-reservoir for urine before it leaves the body
-aided by the urethra, expels urine from the body
RATIONALE: This answer is correct because it accurately describes the role of the bladder in storing urine before it is
expelled from the body, which directly addresses the question's focus on the function of a specific organ. The mention of
the urethra aiding in the expulsion of urine further supports this answer by highlighting the physiological process involved in
eliminating waste from the body.
QUESTION 7
what could occur to a weak response of adh ?
CORRECT ANSWER
increase urine volume with dilute urine,
RATIONALE: ADH (antidiuretic hormone) plays a crucial role in regulating water reabsorption in the kidneys, and a weak
response of ADH can lead to decreased water reabsorption, resulting in an increase in urine volume. As the kidneys
produce dilute urine due to the reduced water reabsorption, the body compensates by producing more urine to remove
excess water, increasing urine volume.
QUESTION 8
the inner layer of the kidney is the __________
CORRECT ANSWER
medulla
RATIONALE: The medulla is the inner layer of the kidney because it is the region primarily composed of renal pyramids,
which are cone-shaped structures that contain the renal tubules where the primary filtration and concentration of urine
occur. This distinct region is characterized by a high concentration of nephrons, the functional units responsible for filtration,
making it a critical component of the kidney's inner layer.
