Which Type of Veins Connect Two Primary Capillary Networks

Question

Which type of veins connect two primary capillary networks?
A) Portal veins
B) Venous sinuses
C) Venules
D) Vaso vasorum

Accepted Answer

Portal veins are the type of veins that connect two primary capillary networks, facilitating the transport of blood from one group of capillaries to another before it returns to the heart. This is seen in the hepatic portal system, where blood from the gastrointestinal tract is transported to the liver's capillary beds for processing before returning to the heart.
