Abdominal aorta

Enter kidney by the Renal artery

Segmental arteries

Interlobar arteries

(-medullary junction)

Arcuate arteries

InterlobULar arteries

(supply Blood for filtration)

Afferent arterioles

(toward renal corpuscle)

Glomerulus

Efferent arteriole (ductile??)

(carries blood away)

→ cortical nephrons or juxtamedullary nephron

Peritubular capillaries or Vasa recta

InterlobULar veins

Arcuate veins

Interlobar veins

Renal vein

IVC

PCT (proximal convuluted tubule)

Nephron loop

DCT(distal convoluted tubule)

Collecting duct

Papillary duct

Minor calyx

Major calyx

Renal pelvis

Ureter

Urinary bladder

Urethra

1) Peritubular capillaries of cortical nephrons

2) Vasa recta of juxtamedullary nephrons

Reproductive sys

Homologues

            Ovary & testis

=produce gametes & sex hormones

            Clitoruis & Glans of penis

=contain autonomic nervous sys axons that stimulate arousal & sexual climax feelings, erectile strucs w/ erectile tissue (homo)

            Labia majora & Scrotum

=Protect & cover some reproductive structures(homo)

            Vestibular glands & Bulb glands

=Secrete mucous for lubrication

Perineum

landmarms

Synthesis pubis, Ishial tuberositys & coccyx

Fem= vestibule (houses urethral orifice & vaginal orifice)

Male = scrotum & base of penis

When temp is cold will elevate testis toward body 2 keep them warm

When hot these muscles relax allowing testes 2 lower away from body 2 keep cool

What muscle does this

(male)

Pathway of Sperm

▒Semifernous tubules(sperm produced here)-

▒Efferent ductules-

▒Epidymis-

▒Vas deferens- Seminal vesicle duct –

▒Ejaculatory duct (same tissue lines it as above) – urethra(surrounded by prostate gland) –

▒Prostatic urethra (lined w/ transitional epi) –

▒Membranous urethra (columnar epi)(contains bulb glands),

▒Penile urethra (lined w/ proximally squdo strat colu epi & distally lined by stratified squamous epi 4 protect)-

▒Urethral orifice

Occurs w/in the semiferous tubules

-Spermatogonium: 2n=46 (diploid) undergo mitosis

-Primary spermatocyte: 2n= result of 1st M division

-Secondary spermatocyte: 2n= result of 2nd M division

Spermatids: (most mature)

Spermatozoa????

Ovarian Follicles

= oocyte surrounded by follicle cells

Primordial follicle

= primary oocyte (an oocyte thats stuck in the

first meiotic prophase)

Primary follicle

= primary oocyte surrounded by one or more layers of cuboidal follicular cells.

Secretes estrogen which stimulates changes in the uterine lining.

Secondary follicle

= primary oocyte, many layers of follicular cells, & fluid-filled space(antrum). 

Zona pellucida is a translucent structure that contains glycoproteins.

Corona radiate is the innermost layer of follicle cells. Secretes estrogen which stimulates changes in the uterine lining.

Vesicular follicle= secondary oocyte, #s layers of follicular cells, large crescent-shaped fluid filled antrum.

Secondary oocyte completes meiosis I

and is stuck in the second meiotic metaphase.

Corpus luteum: The remnants of the ruptured vesicular follicle. Does NOT contain an oocyte. Secretes sex hormones progesterone and estrogen.

(only in 1st 3 months of pregnancy, then the placenta does it)

Corpus albicans: White, connective tissue scar that is formed by the breakup of the corpus luteum. Most get resorbed. 

Ovarian cycle

(3 phases)

Hypothalamus release GnRH,

which stimulates Anterior Pituitary

2 release FSH (follicle stimulating hormone)

& LH (Lutenizing hormone)

Uterine (menstrual cycle)

& include hormone levels

CPS question

During the follicular phase of the ovarian cycle:

FSH & LH r ____, the follicle finally matures 2 a _____, & the endometrium is ______.

Relatively high

Vesicular follicle

Building up

CPS

Fertilization of egg in female

Sperm goes from (in female)

1) Oocyte ovulates from ovary

2) Enters body of uterus

3)Enters uterine tube

4)Fimbriae of infundibulum sweep oocyte inside

5)Travels thru isthmus

6)Travels thru ampulla of uterine tube

7) If fertilized implants into endometrium

SPERM

1) Body of uterus

2)Isthmus

3) Ampulla
