Sigmund Flexure

Tunica Albuginea

Scrotum

Right kidney

More cranial
– Contacts caudate lobe of the liver

Left kidney

More caudal (except in pig)
– Located medially in ruminants

Fibrous Capsule

Thin, fibrous tissue that covers external surface

Renal Hilus

Medial, indented border of kidney
• Opens into the renal sinus
• Entrance for renal vessels & ureter

Ureter

Muscular tube that propels urine from kidneys to urinary
bladder

Renal Artery

Brings oxygenated blood to the kidney

Renal Vein

Carries deoxygenated blood from kidney

Adrenal Gland

Endocrine glands located cranially and medially to each
kidney
• Secrete many hormones

Cortex

Outer layer of the kidney’s parenchyma
– Contains the convoluted tubules & renal corpuscle

Medulla

Internal portion of kidney’s parenchyma
– Contains the Loop of Henle and collecting duct

Urinary Bladder

Hollow & Distensible
– Passes urine from ureter to urethra

Urethra

Tubular
– Transports urine from bladder
– Female: opens into floor of repro tract
– Male: divided into 2 parts (pelvic & penile)

Ovaries

primary female reproductive organs

Cortex of the Ovary

External portion

Medulla of the Ovary

Internal portion

Infundibulum

Move oocyte towards the uterine tube

Uterine Tube

Fallopian Tube or Oviduct
• Transport ova & sperm

Cervix

most caudal, tough & fibrous

Body

between cervix & uterine horns

Uterine Horns

extension of body

Vagina

between cervix & external orifice

Vulva

external portion of female tract

Vestibule

shared space for urinary & repro tracts

Testis

• Produce male gametes & release hormones
• Develop in abdomen & migrate to scrotum

Tunica Albuginea

fibrous covering of the testicle

Endocrine Activity of the Testicle

• Leydig cells → produce testosterone
• Sertoli cells → stimulate spermatogenesis

Scrotum

Retains the testis, epididymis, and distal spermatic cord

Epididymis

Site of sperm maturation and storage

Head of Epididymis

concentrate sperm
• Receives efferent ducts

Body of Epididymis

acquire mobility

Tail of Epididymis

houses mature sperm

Ductus Deferens

Transitions into spermatic cord
• Leaves scrotum
• Crosses beneath ureter & penetrates prostate

Spermatic Cord

• Receives deferent duct
• Cremaster muscle located within the cord

Pampiniform Plexus

• Complex arrangement of veins around artery
• Cools blood before reaching testicle

S‐shaped curve in the ruminant
and boar
