Urinary/Reproductive System
| Question | Answer |
|---|---|
| ureters | transports urine from kidneys to urinary bladder |
| nephron | functional unit of the kidneys |
| filtration, reabsorption, concentration of Na+, secretion, reabsorption of water | major steps in formation of urine |
| cortex | outer part of kidney |
| diuresis | increased production of urine, helps reduce BP |
| antidiuresis | decrease in the production of urine |
| excretion, regulate blood pressure, maintain blood pH (by controlling H+ concentration) | functions of the kidneys |
| excretion | removal of metabolic waste |
| testes | male gonads |
| ovaries | female gonads |
| testosterone | male hormone |
| estrogen and progesterone | female hormones |
| SEVEN UP;Seminiferous Tubules, Epididymis, Vas Deferens, Ejaculatory Duct, Nothing, Urethra, Penis | path of sperm through reproductive tract |
| epididymus | where sperm matures |
| inguinal canal | opening into abdominal cavity in which the sperm duct enters |
| follicle stimulating hormone | stimulates production of sperm |
| luteinizing hormone | stimulates cells to produce testosterone |
| follicle stimulating hormone | stimulates production of estrogen |
| luteinizing hormone | stimulates production of progesterone |
| vagina | birth canal |
| uterus | womb |
| oviduct (fallopian tube) | where fertilization occurs |
| about 28 days | how long are the ovarian and uterine cycles? |
| endometrium | inner lining of the uterus |
| placenta | organ of exchange between the fetus and mother |
| they shorten | What happens to muscle when they contract? |
| origin | stationary bone to which muscle attaches |
| tendons | attach muscle to bone |
| smooth, cardiac, skeletal | 3 types of muscles |
| walls of internal organs | where are smooth muscles? |
| heart | Where are cardiac muscles? |
| attached to the bone | Where are skeletal muscles? |
| antagonistic pairs | muscles that work opposite each other; how skeletal muscles typically occur |
| brain and spinal cord | components of Central Nervous System |
| motor pathways, sensory pathways | components of Peripheral Nervous System |
| automatic motor pathways (involuntary) | sends impulses to smooth muscle |
| somatic motor pathways (voluntary) | innervates skeletal muscles |
| dendrites, cell body, axons | 3 parts of the neuron |
| dendrites | transmits impulses toward the body |
| cell body | site of nucleus and organelles |
| axons | transmits impulses away from cell body |
| medulla | middle part of kidney |
| renal pelvis | inner cavity of kidney, collects urine |
| glomerulus | cluster of capillaries |
| proximal convoluted tubule | twisted, near the beginning of nephron |
| loop of Henle | U-shaped portion of nephron |
| distal convoluted tubule | twisted end of nephron |
| collecting duct | long end of nephron that collects urine |
| long, away from | motor neurons have _________ axons and they transport impulses ________ the central nervous system |
| nerve | consists of long dendrites and/or axons and transport impulses |
| 12 pairs | number of cranial nerves humans have |
| 31 pairs | number of spinal nerves humans have |
| endocrine glands | produce hormones and secrete into blood |
| exocrine glands | produce/releases substances; doesn't secrete into the blood |
| pituitary gland | master gland |
| insulin and glucagon | hormone pancreas secretes |
| epinephrine | hormone adrenal gland secretes |
| antidiuretic, gonadotropic, and growth hormones | hormone pituitary gland secretes |
| testosterone, estrogen, and progesterone | hormone gonads secrete |
