Afferent means going towards a center, in this case, a vessel going towards a lymph node. Efferent means going away from center, in this case, these are vessels associated with the thymus and spleen.
A vessel can be both afferent and efferent if it leaves a peripheral lymph node (where it's efferent to the node) and connects to a greater node, where it becomes an afferent vessel as it enters the greater node or a lymphatic duct.
Afferent vessels: Carry fluid/blood from body organ to heart.
Efferent vessel : Carry fluid/blood from heart to body organ.
A simple branched gland has only one duct with more than one are that secretes into that duct. Compound glands have multiple ducts leading into the main duct.
cochlear duct
The bile duct.
Hepatic duct is attached with liver. The union of hepatic duct and cystic duct forms common bile duct.
The Cystic duct from the gallbladder and the Common Hepatic duct from the liver
renal artery - peritubular network - afferent arteriole - efferent arteriole - renal vein
Duct tape.
Duct tape is made out of plastic, gaffer tape is made out of cloth.
sweat glands :are small tubular structures of the skin that produce sweat. sweat duct :a small duct that conveys sweat from a sudoriferous gland to the surface of the skin.
The scrotum is the outer fleshy sack that holds the testicles. The sperm duct (vas deferens) runs from the testicles and is inside the scrotum.
Tuck tape is much stronger and has better adhesive.
The vasa recta. It is the main capillary that collects the filtered blood from the afferent tubule.
Semineferous tubules, straight tubules, rete testes, efferent ducts, ductus deferens (vas deferens), ejaculatory duct, prostatis urethra, membranous urethra, spongy urethra, external urethral orifice.Testes (Testis) -> Epididymis -> Vas Deferens -> Urethra.

"Pipe" usually implies high pressure, gas or liquid. "Duct" implies low pressure, usually air. Pipes are generally round and made in standard sizes. Ducts can be any shape, any size.
The cystic duct lies between the gallbladder and the common bile duct. Its' function is to transport bile from the gall bladder to the common bile duct.
The alveolar duct
