Which is the solely capillary that open up into a capillary?

Veins usually open up into the heart. Can someone tell me which is the vein that open up into a capillary or some other organ?
Answers:
The VENULE connects the VEIN to the capillaries, this is where gaseous exchange take place as the ARTERIOLES connect the ARTERY to the capillaries

And the VENA CAVA (largest vein) connects the the heart Source(s): General Knowledge
Veins all return blood toward the heart. Each capillary has an arterial side, where blood comes into the capillary, and a venous side, where on earth blood is directed toward a venule, which is a tiny vein that leads to a larger vein. Venules cancel when they open into in larger veins, and the larger vein direct blood to the vena cava. The vena cava is the largest vein, and collects blood from all of the veins that bring blood posterior to it from all of the organ systems of the body (except lungs). The vena cava then directs the blood back into the right atrium of the heart. The blood is consequently circulated through the lungs, and returns through pulmonary veins directly to the left atrium of the heart (not the vena cava) after picking up oxygen.

The answer to your question is venules.....and they are not thought of as channel up into capillaries so much as opening out away from capillaries, since they direct the blood spinal column out of the capillaries to be returned toward the heart.. Source(s): RN
the vein in your body get smaller and smaller into arterioles and capillaries Source(s): EMT-B
Actually it goes Artery (oxygenated, from heart), arteriole, capillary, venule, capillary (deoxygenated, to heart) as I recall.
Can't find proof for my theory but I suspect the answer to your question is any a) kidneys, the body's refuse treatment station or b) the heart.

Good luck.
I can't find a specific answer to your question.
Portal vein (common name)-a short, gooey trunk formed by the union of superior mesentric and splenic vv behind the neck of pancreas; it ascends to right call a halt of porta hepatis, where it divides into successively small branches, following branches of hepatic artery, until it forms a capillary like system of sinusoids that permeates entire substance of liver.
In the overnight case of portal vein, blood flows through the liver to form hepatic vein and thus joins inferior vena cava. But surrounded by the case of cirrhosis patients, portal venous blood bypasses the liver to join venules in the esophagus and join directly to inferior vena cava. The portal venous pressure is high and blood pressure in inferior vena cava is low. This causes the capillary in the esophagus to dilate causing esophageal varices.

Are you thinking of the hepatic portal vein? It transports blood to the liver, and divides up into numerous capillaries, which deliver blood to the liver tissues. Source(s): Professor of Zoology
The anatomical name for a vein which drains into a capillary system is portal vein. The most up to date portal vein is the hepatic portal vein, which receives blood from the vein draining the gut and the spleen and drains into the liver. However, this is not the only one. There is another portal vein at the base of the brain, running between the hypothalamus and the anterior (front) portion of the pituitary gland. Source(s): Gray's Anatomy
diverse Wikipedia articles
Portal capillary runs between 2 capillary beds, but you need to go fund and study your anatomy because "veins" do not "open into the heart"
