Which of the following is NOT a function of the kidneys?
regulate body fluid by controlling excretion from sweat glands
Which statement does NOT accurately describe the renal gross anatomy?
The left kidney is lower in position because of crowding by the liver.
The __________ collect(s) urine, which drains continuously from the papillae; the urine is then emptied into the __________.
calyces; renal pelvis
Efferent arterioles supply blood to the glomerulus.

false

Which structure is INCORRECTLY matched with a function?
nephron loop: secretion

Where in the nephron does most solute reabsorption occur?
proximal convoluted tubule
Capsular hydrostatic pressure is the chief force pushing water and solutes out of the blood and across the filtration membrane.

false

A relatively large afferent arteriole on one side of the glomerulus compared to a relatively smaller efferent arteriole creates an increase in hydrostatic pressure that drives glomerular filtration.

true

Approximately 80% of the energy used for active transport is devoted to the reabsorption of

sodium

Under normal conditions, the proximal convoluted tubule (PCT) reabsorbs all of the glucose, lactate, and amino acids in the filtrate and 65% of the Na+ and water.

true

Upon reaching what point in the nephron is reabsorption (1) dependent upon the body's needs at the time and (2) regulated by hormones?
distal convoluted tubule
The ascending limb of the loop of Henle is permeable to water.

false

External chemicals that enhance urinary output are called __________.
diuretics
The longer the nephron loop descends into the medulla, the less concentrated the urine will be.

false

The __________ is a skeletal muscle under conscious control that allows urine to leave the bladder.
external urethral sphincter
Which of the following is NOT one of the things that must happen for micturition to occur?
The extrusor muscle must relax.
Which of the following would NOT inhibit micturition?
detrusor contraction
Which of the following is considered a role of primary sex organs?
production of sex hormones
Viable sperm production is optimal below the body's core temperature.

true

Which male reproductive structure is NOT correctly matched with its function?
epididymis: produce sperm
Sperm is produced in the __________.
seminiferous tubules
Which gland is NOT matched with its type of secretion?
urethra: clear, viscous mucus that neutralizes urine
The number of chromosomes in a human gamete is __________; this is referred to as a __________ chromosome number.
23; haploid
Spermatogenesis is meiotic cell division that produces four genetically identical sperm cells.

false

Genetic variation of individual chromosomes occurs during __________.
prophase I
Which of the following would most directly interfere with sperm production?
interruption of sustentocytes' production of ABP
Which portion of the sperm contains the enzymes needed to penetrate the oocyte?
acrosome
The release of __________ encourages sustentocytes to release __________.
ollicle-stimulating hormone; androgen-binding protein
Which of the following female sex hormones is most responsible for estrogenic effects?
estradiol
The membrane surrounding the ovary is the tunica albuginea

true

It connects the uterus to the labia majora.
The __________ is shed during each menstruation and is then regenerated by the __________.
stratum functionalis; stratum basalis
The mammary glands are well developed in all females.

false

Which of the following is FALSE regarding the vagina of an adult female?
The pH of the adult vagina is alkaline.
Oocytes complete meiosis II before they are fertilized.

false

Formation of a secondary oocyte occurs during _________
the follicular phase
A surge in __________ directly triggers ovulation.

LH

During the secretory phase of the uterine cycle, __________.
the endometrium prepares for implantation
Which of the following is an effect of estrogen in females?
promotes oogenesis
In females, orgasm is required for fertilization.

false

The __________ develop into the female duct system.
paramesonephric ducts
