What is the most superficial tissue of the kidney?

Renal Fascia 

100

What arteriole brings blood towards the glomerulus?

Afferent arterioles 

100

What pressure moves out of the glomerulus?

Glomerular Blood Hydrostatic Pressure 

100

How many phases are in the ovarian cycle? what are the names?

2; follicular phase and luteal phase 

100

what process makes identical body cells and is important for growth 

Mitosis 

200

What is the most deepest tissue layer of the kidneys?

Renal capsule 

200

Where does a lot of reabsorption happen in the nephron?

Proximal Convoluted Tubule (PCT)

200

What are the 2 inward pressures?

Capsular hydrostatic pressure & Blood colloid osmotic pressure 

200

What causes the oocyte to be ejected?

LH surge (lutenizing hormone)

200
what process contributes to genetic variety 

Meiosis 

300

What part of the internal kidney separates the renal pyramids? 

Renal Columns 

300
Why does the filtrate become more concentrated when it is makes it way through the descending tubule?

The DT is permeable to water so water is leaving the filtrate making it more concentrated

300

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 

300

leydig cells that surround the seminiferous tubule secrete what hormone that promotes spermatogenesis?

testosterone 

300
When does the oogonia undergo mitosis?

before birth 

400

What carries urine to the outside of the body? 

urethra 

400

What are the two hormones that affects the permeability of the collecting duct to water?

Aldosterone & ADH

400

Vasoconstriction  of the afferent arterioles & vasodilation of the efferent arterioles will ____ NFP and ___ GFR which will ____ urination

decrease NFP, decrease GFR, decrease urination 

400

Which hormone is the dominant hormone during the follicular phase?

estrogen 

400

During oogenesis, when does a primary oocyte undergo Meiosis I?

During ovulation 

500

What is the flow of urine?

kindey-->ureter-->bladder-->urethra 

500

Draw and label the parts of the nephron

Glomerulus, Bowman’s Capsule, PCT, DT, LH, AT, DCT, CD 

500

What increases NFP and GFR?

Vasodilation of the afferent arterioles

vasoconstriction of the efferent arterioles  

500

What is the function of estrogen in the female reproductive cycle?

promote growth of the endometrial lining during the proliferative phase 

500

During spermatogenesis, what is a mature spermatid called?

spermatozoan
