A&P 3 FINAL Flashcards
Distal convoluted tubule
Urine flows through the loop of henle into here, aldosterone.
Peritubular capillaries
Reabsorption happens
Afferent arterioles
Become glumerulus
Efferent arterioles
Carry filtered blood out of glumerulus become Peritubular capillaries
Proximal convoluted tubules
Extends to loop of henle
Calyces
Receive urine from collect duct, collect urine formed in the kidney, collecting duct send urine to minor calyces.
Bladder (storage tank)
Can hold up to 700-800 ml of urine
Ureter (2)
Located between renal pelvis & bladder.
Bowman’s capsule
Collects filtrate from the glumeruli , surrounds glumerulus in nephron.
Creatinine
Waste product that filtered (not reabsorbed)
Micturition
Expulsion of urine
Erythropoietin ( hypoxia stimulates)
Secreted by kidneys
Scrotum
Pouch like sac that holds the testes
Placenta
Forms in uterus with baby, highly vascular, how the baby breathes,replaces secretion of corpus lutium.
Myometrium & endometrium
Myometrium: the muscular layer of the uterus.
Endometrium: Mucous membrane lining uterus (inner)
Sperm anatomy
Head, flanglum
Mid Piece
Fundus
Rounded top of uterus
Estrogen
Promotes ova maturity of egg
Secondary sex characteristic
Secreted by ovaries
Sperm tract
Vas defrens, ejaculatory duct , urethra
Prostate gland
Lies below bladder, secretes fluid about 30% seminal fluid volume, helps activate sperm & maintain motility.
Zygote
Fertilized ovum (egg)
Embryo
First 3 months after conception
3-8 weeks
Hypothalamus (control center)
Secretes releasing hormones that control anterior pituitary
ADH , Oxytocin
Goiter
Enlarged thyroid
Lactogenic hormone
Prolactin
Stimulates mammary gland to produce milk
Hypothalamic releasing hormones (anterior)
Growth hormone, prolactin, thyroid stimulating hormone, adrenocoiticotropic hormone, follicle stimulating hormone.
Growth hormone (secreted by adenohypothesis)
Somototropin, increases blood glucose levels. Growth of skeletal muscle/ skeleton.
Calcitonin & PTH
Calcitonin- decreases blood calcium, deposits calcium on bone, PTH stimulates calcium to move from bone into blood, increased. (Osteoblast)
Oxytocin (swift birth)
Stimulates muscles in uterus to contact , also let down response for milk production.
cAMP
Cyclic adenosine monophosphate
Secondary chemical messenger
Insulin
ONLY hormone that lowers blood glucose
ACTH (salt,sex,sugar)
Stimulates adrenal cortex to secrete steroids cortisol.
Testosterone (androgen)
Male sex hormone, made in testes, sperm formation, sex characteristic.
Neurohypophysis
Posterior pituitary gland
Pineal gland
Secreted melatonin, maintains biological rhythms
Vagus nerve
Stimulates/ controls digestive tract
Bile
Digestive juice
Produced in liver
Stored in gallbladder
