urinalysis
The renal pelvis drains into the:
ureter
When gametes unite, they form:
zygote
Which of the following is true of estrogen?
It is produced by the granulosa cells around the oocytes and stimulates both the proliferation of the epithelial lining of the uterus and the develop and maturation of the female reproductive organs.
The part of the female reproductive cycle that begins at ovulation and ends at the start of menses is
the secretory phase

seminal vesicles
The number of spermatids that come from one primary spermatocyte is
4
The sperm precursor or stem cell is called
spermatogonia
After ovulation, the hormone-secreting remnant of the follicle is called the
corpus luteum
The brain, spinal cord, and lens and cornea of the eye develop from the primary germ layer called the
ectoderm
The prenatal period begins at
conception and ends at birth
The fertilized egg is called
zygote
The term fetus is used
after the first 8 weeks of pregnancy.
If a birth defect were said to be caused by a teratogen, it was caused by
an environmental factor.
As the respiratory system ages
the costal cartilage harden, a condition called “barrel chest” develops, and the strength of inspiratory and expiratory muscles decreases.
The normal adult urine output is about:
1500 mL/day
The kidneys do not play a vital role in regulating:
blood glucose level.
A nitrogen-containing waste product excreted by the kidney is
ammonia and urea
What condition occurs when the bladder is able to empty itself but no urine is being produced by the kidneys?
Suppression
The proximal convoluted tubule connects
glomerular capsule and nephron loop.
Emptying of the bladder is called:
voiding, urinating, and micturition
Which important mineral cannot be reabsorbed by the kidney?
Potassium
As the urinary system ages:
the number of nephrons decreases, the blood flow to the kidney is reduced, and the muscles of the bladder begin to atrophy.
he circulatory system, gonads, and muscles develop from the primary germ layer called the
mesoderm
The longest stage of labor is usually:
stage 1
The baby’s first breath is stimulated primarily by
the accumulation of carbon dioxide in the blood.
The emptying reflex causes the
both the contracting of the muscles of the bladder and relaxation of the internal sphincter
Which of the following is not true of ADH?
It increases the amount of urine produced
the kidneys are
retroperitoneal.
Which of the following do not help protect the kidney?
the hip bone
Most of the water in the nephron is reabsorbed by the:
proximal convoluted tubule
Which of the following structures is (are) not part of the renal corpuscle?
Nephron loop
he dissolved substances and fluid that move from the glomerulus into Bowman capsule are called
glomerular filtrate
Sperm cells develop in the
seminiferous tubules.
Sperm mature and develop their ability to move and swim in this structure:
epididymis
During the reproductive lifetime of most women, about how many of the primary follicles fully develop into mature follicles?
350 to 500
This structure is the target organ for gonadotropin-releasing hormone (GnRH):
the anterior pituitary gland
As a girl goes from being a newborn to puberty
less than half of the ovarian follicles become primary follicles.
Oogenesis differs from spermatogenesis because in oogenesis
polar bodies are produced
Which of the following is not a function of testosterone?
t causes spermatogonia to undergo a unique kind of cell division at puberty.
Which of the following is not true of the penis?
It has two columns of corpora spongiosum, which surrounds the urethra
The hormones LH and FSH are produced by the:
anterior pituitary gland.
The part of the female reproductive cycle that involves passage of part of the inner lining of the uterus and blood is:
menses
This structure in the testes secretes testosterone
interstitial cells.
The muscle layer of the uterus is called the
myometrium
The corpus luteum functions as an endocrine gland during part of the female reproductive cycle is called
the secretory phase
If estrogen in the female is the counterpart of testosterone in the male, then which part of the ovary would be the counterpart of the interstitial cells of the testes?
Granulosa cells
The ejaculatory duct forms as a result of the joining of the:
ductus deferens and the seminal vesicle duct.
An increase in the pressure inside the eyeball is called:
glaucoma.
Calcification or “hardening” of the arteries is called
atherosclerosis.
By the time the fertilized egg reaches the uterus, it is a hollow ball of cells called a:
Keyword B
blastocyst
The condition in which the lens of the eye becomes cloudy is called
a cataract.
Which condition occurs when a person urinates involuntarily?
Incontinence
The cells of the juxtaglomerular apparatus help regulate
blood pressure
Which part of urinating is under voluntary control?
Relaxation of the external sphincter
Most of the water in the nephron is reabsorbed by the
proximal convoluted tubule

Substances to be reabsorbed must pass through how many barriers to get to the blood?
three
The nephron is composed of the
renal corpuscle and renal tubules
