Urinary and Reproductive Structures

Kidney

Waste removal, osmo regulation. Kidneys form mesoderm. Plays role in urinary (waste removal) and endocrine system (hormone production)

Medulla

Water retention broken up into pyramids

Cortex

Filter blood, modify filtrate

Nephron

Site of filtration inside kidneys, urine is produced here

Glomerulus

Bowman’s capsule

Proximal convoluted tubule

Descending nephron loop

Ascending nephron loop

Distal convoluted tubule

Macula densa

Collecting duct

Renal Pyramids

Major calyx

Minor calyx

Renal Pelvis

Renal vein

carries filtered, deoxygenated blood from each kidney back into the systemic circulation

Renal artery

carry a large volume of oxygen-rich blood directly from the abdominal aorta into the kidneys for filtration

Ureter

transport urine from the kidneys to the urinary bladder for temporary storage

Bladder

-Hallow muscular reservoir

-Stores urine produced by the kidneys, until elimination

-Transitional epithelial

-Detrusor epithelial 

Urethra (Female)

• Exit

• Transport urine from the bladder to the outside of the body during urination

Urethra (Male)

Ovary

Follicle

Infundibulum

Oviduct

Uterus

Cervix

Vagina

Vaginal orifice

External vaginal opening

Mammary glands

Urethral orifice

external exit of urethra

Scrotum

Cremaster Muscle

Testis

Seminiferous tubules

Make sperm

Leydig cells

specialized, testosterone-producing endocrine cells located in the interstitial space (the connective tissue) between the seminiferous tubules of the testes

Epididymis

Vas deferens

Inguinal canal

Prostate Gland

Seminal vesicle

Bulbourethral gland

Penis
