- Ductus Deferens. The ductus deferens, also known as the vas deferens, is a tiny muscular tube in the male reproductive system that carries sperm from the epididymis to the ejaculatory duct.he ductus deferens serves dual functions in the male reproductive system: 1  Transporting sperm from the testes to the ejaculatory duct and urethra. 2  Storing sperm until it is ready to be ejaculated.

Patent ductus arteriosus Patent ductus arteriosus (PDA) is a condition wherein the ductus arteriosus fails to close after birth. Early symptoms are uncommon, but in the first year of life include increased 'work of breathing' and poor weight gain. An uncorrected PDA may lead to congestive heart failure with increasing age. The ductus arteriosus is a fetal blood vessel that closes soon after birth. In a PDA, the vessel does not close and remains patent (open), resulting in irregular transmission of blood between the aorta and the pulmonary artery.

Human Physiology/The male reproductive system The male reproductive system consists of the testes and a series of ducts and glands. Sperm are produced in the testes and are transported through the reproductive ducts. These ducts include the epidrimys, vas deferens, ejaculatory duct and urethra.

Prostate During male ejaculation, sperm is transmitted from the ductus deferens into the male urethra via the ejaculatory ducts, which lie within the prostate gland. It is possible for some men to achieve orgasm solely through stimulation of the prostate gland, such as prostate massage or receptive anal intercourse.

What is the function of the ductus arteriosis? The ductus arteriosis (DA) is a normal part of the fetal circulation. It is a shunt (or a short vessel) that connects the pulmonary artery and descending aorta. Functions of DA include: As part of the normal physiology, the DA starts closing once the baby is born and the lungs inflate, establishing breathing.

Ejaculatory duct The ejaculatory ducts (ductus ejaculatorii) 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 Colliculus seminalis. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the tip of the penis.perm is produced in the testes and enters the ejaculatory ducts via the vas deferens. As it passes by the seminal vesicles, a fluid rich in fructose combines with sperm. This addition nourishes the sperm in order to keep it active and motile.

Epididymis The epididymis (plural, epididymides) is a tightly coiled mass of thin tubes that carries sperm from the testes to the ductus deferens in the male reproductive system. Sperm matures as it passes through the epididymis so that it is ready to fertilize ova by the time it enters the ductus deferens. The epididymis is a crescent-shaped coil of thin tubules located inside the scrotum and posterior to the testis.

How Much Does a Fake Tooth Cost? A 2 to 6 implant with dental bridge can cost anywhere between $3500 to $5,000 depending on the work which is required. This is due to the complexity of the implant, how it looks, and where it positions within your mouth. A survey conducted by Choice.com.au shows some of the additional costs involved.

Vas Deferens - definition, what is and function Vas Deferens - definition, what is and function. What is Vas Deferens and Function of Vas Deferens. A narrow tube that carries SPERM from the epididymis to the ejaculatory duct during ORGASM and EJACULATION. One vas deferens, also called a ductus deferens, arises from each testicle. The smooth-MUSCLE walls of the vas deferens contract and relax in wavelike movements to propel sperm from the testicle to mix with seminal fluid, which then carries the fluid (SEMEN) from the PENIS during ejaculation.

patent patent ductus arteriosus (PDA) abnormal persistence of an open lumen in the ductus arteriosus, between the aorta and the pulmonary artery, after birth. The ductus arteriosus is open during prenatal life, allowing most of the blood of the fetus to bypass the lungs, but normally this channel closes shortly before birth.

Seminal Vesicle Anatomy The seminal vesicles are paired organs of the male genitourinary system. Specifically, they are genital organs. The male genital organs include the penis, testes, excretory genital ducts, ductus deferens, seminal vesicles, prostate, and bulbourethral glands.Of these organs, the seminal vesicles, prostate, and bulbourethral glands are considered accessory glandular structures.pecifically, they are genital organs. The male genital organs include the penis, testes, excretory genital ducts, ductus deferens, seminal vesicles, prostate, and bulbourethral glands.

Reproductive System The epididymis and the vas deferens make up the duct system of the male reproductive organs. The vas deferens is a muscular tube that passes upward alongside the testicles and transports the sperm-containing fluid called semen. The epididymis is a set of coiled tubes that connects to the vas deferens.

Overview of the Male Reproductive System Vas deferens: The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. The vas deferens transports mature sperm to the urethra, the tube that carries urine or sperm to outside of the body, in preparation for ejaculation. Ejaculatory ducts: These are formed by the fusion of the vas deferens and the seminal vesicles (see below). The ejaculatory ducts empty into the urethra. Urethra: The urethra is the tube that carries urine from the bladder to outside of the body.

Patent Ductus Arteriosus (PDA) The ductus arteriosus is a hole that allows the blood to skip the circulation to the lungs. However, when the baby is born, the blood must receive oxygen in the lungs and this hole is supposed to close. If the ductus arteriosus is still open (or patent) the blood may skip this necessary step of circulation.he ductus arteriosus is a normal fetal artery connecting the main body artery (aorta) and the main lung artery (pulmonary artery). The ductus allows blood to detour away from the lungs before birth.
