Where urine is stored before urination through the urethra, to the outside.
URINARY BLADDER.
The FUNCTIONAL units of the kidney are the
NEPHRONS
THE ________ filter waste material OUT OF THE BLOOD brought to the kidney by the RENAL artery.
NEPHRONS
The waste filtration occurs through the GLOMERULUS in _______ capsule of the nephroN under the force of ______ pressure.
BOWMAN’S
Blood
Urinary system:
Components needed by the body such as water, glucose, and ions leave the NEPHRON by ________ and REENTER THE BLOOD.
DIFFUSION
Water is reabsorbed at the ______ of the nephron.
TUBULES
THE FINAL PRODUCT PRODUCED BY MILLIONS OF NEPHRONS PER KIDNEY IS
URINE.
the male and female sex organs have 2 functions:
Production of gametes (sex cells)
And
Production of hORMONES.
MALE AND FEMALE SEX ORGAN FUNCTIONS are under the control of TROPIC HORMONES from the ________ gland.
Anterior PITUITARY
Reprodcutive activity is ____ in women but ______ in men.
Cyclic in women
Continuous in men.
The gamets are formed by mitosis/meiosis?
Meiosis.
In men, SPERMATOZOA develop within the ____________ tubules of EACH TESTIES.
SEMINIFEROUS
WHAT PRODUCES TESTOSTERONE in men?
The interstitial cells BETWEEN the seminiferous tubules.
Testosterone influences sperm cell development and also produces the male SECONDARY SEX CHARACTERISTICS:
BODY HAIR AND DEEP VOICE.
Once produces, the sperm are matured and stored in the _____ of EACH TESTIS.
EPIDIDYMIS
DURING EJACULATION the pathway for the sperm includes.
Vas deferens
Ejaculatory duct
Urethra.
The TRANSPORT MEDIUM for sperm is called
Semen.
Testicular activity is under the control of 2. Anterior _______ hormones
Pituitary
______ regulates sperm production
FSH- follicle stimulating hormone
Stimulates the interstitial cells to produce testosterone.
INSTERTITIAL CELL=STIMULATING HORMONE (ICSH) OR LH (liutinizing hormone)
In women, each month under the influence of _______, several eggs ripen within the ovarian follicles in the ovary.
FSH- Follicle Stimulating Hormone
The ______ produced by the FOLLICLE initiates the preparation of the endometrium of the UTERUS for PREGNANCY
ESTROGEN
The _____ _____ secretes the hormones ______ and estrogen which further stimulates development of the endometrium.
Corpus luteum
PROGESTERONE
After ovulation the egg is swept into the
Oviduct or fallopian tube.
Fertilization occurs while the egg is in the
Fallopian tube.
In the uterus the developing embrio is nourished by the
Placenta
In the uterus the developing embrio is nourished by the
PLACENTA
DURING PREGNANCY, HORMONES FROM THE PLACENTA MAINTAIN THE__________ AND PREPARE THE BREAST FOR MILK PRODUCTION
ENDOMETRIUM
______ hormone stimulates ovulation and converts follicle to corpus luteum
LH
