Anatomy of Urinary System
What is the most superficial tissue of the kidney?
Renal Fascia
What arteriole brings blood towards the glomerulus?
Afferent arterioles
What pressure moves out of the glomerulus?
Glomerular Blood Hydrostatic Pressure
How many phases are in the ovarian cycle? what are the names?
2; follicular phase and luteal phase
what process makes identical body cells and is important for growth
Mitosis
What is the most deepest tissue layer of the kidneys?
Renal capsule
Where does a lot of reabsorption happen in the nephron?
Proximal Convoluted Tubule (PCT)
What are the 2 inward pressures?
Capsular hydrostatic pressure & Blood colloid osmotic pressure
What causes the oocyte to be ejected?
LH surge (lutenizing hormone)
Meiosis
What part of the internal kidney separates the renal pyramids?
Renal Columns
The DT is permeable to water so water is leaving the filtrate making it more concentrated
Calculate the NFP:
GBHP: 150 mmHg
CHP: 50 mmHg
BCOP: 20 mmHg
GBPH (out): 150 mmHg
CHP (in) + BCOP (in) = 50 + 20 = 70 mmHg
150-70 = 80 mmHg out
leydig cells that surround the seminiferous tubule secrete what hormone that promotes spermatogenesis?
testosterone
before birth
What carries urine to the outside of the body?
urethra
What are the two hormones that affects the permeability of the collecting duct to water?
Aldosterone & ADH
Vasoconstriction of the afferent arterioles & vasodilation of the efferent arterioles will ____ NFP and ___ GFR which will ____ urination
decrease NFP, decrease GFR, decrease urination
Which hormone is the dominant hormone during the follicular phase?
estrogen
During oogenesis, when does a primary oocyte undergo Meiosis I?
During ovulation
What is the flow of urine?
kindey-->ureter-->bladder-->urethra
Draw and label the parts of the nephron
Glomerulus, Bowman’s Capsule, PCT, DT, LH, AT, DCT, CD
What increases NFP and GFR?
Vasodilation of the afferent arterioles
vasoconstriction of the efferent arterioles
What is the function of estrogen in the female reproductive cycle?
promote growth of the endometrial lining during the proliferative phase
During spermatogenesis, what is a mature spermatid called?
spermatozoan
