Meiosis is necessary because
otherwise the fertilized ovum will have too much genetic material.
The hormone mainly responsible for the development and maintenance of female secondary sexual
characteristics is
estrogen.
Female sex hormones are produced by the
ovaries
The functional unit of the kidney is the
nephron
The ________ is the tube that conveys urine outside the body.
urethra
The organs of the urinary system are
paired kidneys, paired ureters, a bladder and a urethra.
The hormone responsible for the development and maintenance of male secondary sex
characteristics is
testosterone.
Filtration rate in the glomerulus is increased by
both vasodilation of the afferent arteriole and vasoconstriction of the efferent arteriole.
Which of the following indicates the parts of a renal tubule in the correct sequence from beginning to
end?
Proximal convoluted tubule, descending limb of nephron loop, ascending limb of nephron loop, distal
convoluted tubule
The number of sperm cells that form from a primary spermatocyte is
4.
An increase in the level of FSH at approximately day 14 causes ovulation.
False
A renal corpuscle includes the
glomerulus and glomerular capsule.
The hormone ADH promotes water reabsorption through the wall(s) of the
distal convoluted tubule and collecting duct.
