Male and female reproductive system

corpus cavernosum

This is a pair of sponge-like regions of erectile tissue, the corpora cavernosa (plural) (cavernous bodies), which contain most of the blood in the penis during an erection.

Prostatic urethra

Where the urethra passes through the prostate.

fallopian tubes

a pair of tubes with fingerlike projections that draw in the ovum

Prostate gland

adds a chemical fluid to the semen

suspensory ligament of penis

anchors erectile tissue of penis to the pubic symphysis

ampulla of vas deferens

enlarged end of vas deferens which joins the seminal vesicles to empty into the ejaculatory duct

Membraneous urethra

region of urethra that passes through the pelvic cavity in between the prostate and the penis

pubic symphysis

the cartilaginous joint known that allows some movement to facilitate childbirth

bulbourethral glands

the two glands below the prostate that secrete a sticky fluid that becomes a component of semen

ovary

A flower structure that encloses and protects ovules and seeds as they develop.

body of uterus

Accepts fertilized ovum and houses the fetus

urethra opening

In anatomy, the urethra is a tube that connects the urinary bladder to the urinary meatus for the removal of fluids from the body. In males the urethra travels through the penis, and carries semen as well as urine.

ureter

In human anatomy, the ureters are tubes made of smooth muscle fibers that propel urine from the kidneys to the urinary bladder. In the adult, the ureters are usually 25-30 cm (10-12 in) long and ~3-4 mm in diameter. Histologically, the ureter is lined by urothelium a type of transitional epithelium, and has an additional smooth muscle layer in the more distal one-third to assist with peristalsis.

amopulla

The ampulla of ductus deferens is an enlargement of the ductus deferens at the fundus of the bladder.

corpus spongiosum

The corpus spongiosum is the mass of spongy tissue surrounding the male urethra within the penis. Also called the corpus cavernous urethrae in older texts.

Ejaculatory duct

The ejaculatory ducts are paired structures in male anatomy. Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. They pass through the prostate, and open into the urethra at the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the urinary meatus.[

Epididymis

The epididymis is a tube that connects a testicle to a vas deferens in the male reproductive system. It is a single, narrow, tightly-coiled tube, six to seven meters in length connecting the efferent ducts from the rear of each testicle to its vas deferens.

prostate

The function of the prostate is to secrete a slightly alkaline fluid, milky or white in appearance, that in humans usually constitutes roughly 30% of the volume of the semen along with spermatozoa and seminal vesicle fluid.[4] Semen is made alkaline overall with the secretions from the other contributing glands, including, at least, the seminal vesicle fluid.[5] The alkalinity of semen helps neutralize the acidity of the vaginal tract, prolonging the lifespan of sperm. The prostatic fluid is expelled in the first ejaculate fractions, together with most of the spermatozoa.

glans penis

The glans penis is the sensitive bulbous structure at the distal end of the human penis. The glans is anatomically homologous to the clitoral glans of the human female. Typically, the glans is completely or partially covered by the foreskin, except in men who have been circumcised. The foreskin can generally be retracted over and past the glans, and may automatically retract during an erection. The glans is more commonly known as the "head" or the "tip" of the penis.

Cervix

The opening to the uterus

pampiniform plexus

The pampiniform plexus is a network of many small veins found in the human male spermatic cord. It is formed by the union of multiple spermatic veins from the back of the testis and tributaries from the epididymis.

Scrotum

The scrotum is an anatomical male reproductive structure that consists of a suspended dual-chambered sack of skin and smooth muscle that is present in most terrestrial male mammals and located under the penis. One testis is typically lower than the other, which functions to avoid compression in the event of impact.

seminal vesicles

The seminal vesicles are a pair of glands that are positioned below the urinary bladder and lateral to the vas deferens. Each vesicle consists of a single tube folded and coiled on itself, with occasional diverticula in its wall.[2] The excretory duct of each seminal gland unites with the corresponding vas deferens to form the two ejaculatory ducts, which immediately pass through the substance of the prostate gland before opening separately into the verumontanum of the prostatic urethra.

Testis

The testicle or testis is the male gonad in animals. Like the ovaries to which they are homologous, the testicles (testes) are components of both the reproductive system and the endocrine system. The primary functions of the testes are to produce sperm (spermatogenesis) and to produce androgens, primarily testosterone.

testicular artery

The testicular artery (the male gonadal artery, also called the internal spermatic arteries in older texts) is a branch of the abdominal aorta that supplies blood to the testis. It is a paired artery, with one for each of the testes. It is the male equivalent of the ovarian artery. Because the testis is found in a different location than that of its female equivalent, it has a different course than the ovarian artery.

bladder

The urinary bladder is a hollow muscular organ in many animals, that collects and stores urine from the kidneys before disposal by urination. In the human the bladder is a hollow muscular, and distensible (or elastic) organ, that sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra. The typical human bladder can hold between 300 and 500 mL (10.14 and 16.91 fl oz) before the urge to empty occurs

vas deferens

The vas deferens (Latin: "carrying-away vessel"; also called ductus deferens, is part of the male reproductive system of many vertebrates; these vasa transport sperm from the epididymis to the ejaculatory ducts in anticipation of ejaculation. It is a partially coiled tube which ascends into the abdomen through the inguinal canal.
