Urinary System Anatomy
Micturition is the act of
urinating.
Non-specific squeezing of water and solutes in the renal corpuscle is known as
filtration.
Where does fertilization occur?
Ampulla of the uterine tube (also known as the fallopian tube)
What hormone is responsible for developing and maintaining male reproductive organs?
Testosterone
The production of milk by the mammary glands is known as
lactation.
The functional unit of the kidney is the
nephron.
What process of urine formation moves molecules from the filtrate (in the nephron) back into the blood?
Secretion of what hormone causes ovulation?
LH (luteinizing hormone)
What is the purpose of the flagellum located on sperm cells?
Movement
Put these developmental stages in chronological order:
embryo, fetus, zygote, infant
zygote, embryo, fetus, infant
The ________ carry urine from the kidneys to the urinary bladder.
ureters
H+ ions
What structure forms on the ovarian follicle after the oocyte has been ovulated?
Corpus luteum
The prostate gland functions as a "urethral switch", allowing the male urethra to carry fluids from what two organ systems?
Urinary and reproductive
During which stage of labor does the baby exit the birth canal?
Second stage
glomerulus
Secretion of ADH, or antidiuretic hormone, causes the kidneys to reabsorb (more or less) water, which (increases or decreases) the amount of urine produced.
Secretion of ADH, or antidiuretic hormone, causes the kidneys to reabsorb more water, which decreases the amount of urine produced.
What uterine layer is sloughed off during menstruation?
Endometrium
Sperm are produced within the testes in channels known as the _____ ______.
What structure forms from embryonic and maternal tissues and connects the mother and fetus?
Placenta
Place the structures of the nephron in the order that filtrate passes through them
PCT, DCT, Loop of Henle, Renal Corpuscle, Collecting Duct
Renal Corpuscle, PCT, Loop of Henle, DCT, Collecting Duct
What two nephron structures are responsible for the majority of tubular reabsorption?
(PCT, DCT, Loop of Henle, Renal Corpuscle, Collecting Duct)
PCT and Loop of Henle
What hormone is secreted by the corpus luteum and maintains pregnancy?
Progesterone
Place these structures in the order through which sperm passes through them
epididymis, reproductive glands, ducta deferens, urethra, testes
testes, epididymis, ducta deferens, reproductive glands, urethra
What hormone is secreted by the chorion and keeps the corpus luteum functional?
HCG (human chorionic gonadotropin)
