Yes, hogs have veins just like all mammals. Veins are blood vessels that carry blood back to the heart after it circulates through the body.

Blood...
In the blood - which circulates all around the body through a network of arteries and veins.
the heart is good for pumping blood through out the body to all of your veins so your blood circulates and keeps you alive.
Oxygen-rich blood moves from the lungs to the heart, where it is pumped out to the body through the arteries. It circulates through the body's tissues and organs, delivering oxygen and nutrients, before returning to the heart through the veins.
The cardiovascular system circulates blood through the body.
It turns from oxygenated blood to deoxygenated blood. The tissues absorb the oxygen that your red blood cells carry through diffusion through the capillary membranes. When the oxygen is gone, the blood is considered "deoxygenated."
Blood appears dark red as it circulates through the body primarily in the veins, where it is deoxygenated. This occurs after oxygen is delivered to the tissues and carbon dioxide is picked up, resulting in a lower oxygen content. The dark red color is due to the altered state of hemoglobin, which reflects different wavelengths of light depending on its oxygen saturation.
The heart contracts and expands due to it's muscles. The blood is made to go one way only, by the use of Valves between each chamber. Blood circulates through the heart in arteries and veins. They pass through various valves and chambers. Because the heart itself is an automatic pumping machine (or a muscle) the blood is pumped into different organs of the body via the bloodstream.
what veins does it pass through
The two veins are the hepatic portal vein and the splenic vein. They carry blood from the digestive organs and the spleen to the liver, allowing the liver to process and filter out nutrients, toxins, and other substances before the blood circulates through the rest of the body.
