Pulmonary veins
Cats use their tongues to help them eat and drink. They do not sip water as humans do, they lap it up with their tongues. Watch them some time.
There are four main types of veins that pigs and humans have in common. These include the pulmonary, systemic, deep, and superficial veins.
posibly, depending on the circumstances.
The brachial veins of the pig differ from those of humans because of the location. A pig's brachial veins are on the same path as their axillary veins directly to their forearms. Human's brachial veins are on one side of the brachial artery and generally join the axillary vein near the bottom of the Subscapularis.
yes. all living animals and humans have veins. how else would their blood get around? by swimming?
No. There are structures in plants that are called veins, but they work considerably differently from those in humans.

They both carry, or transport blood or nutrients to where the body or plant needs.

My advice is to start with your personal ethics, and your interactions with fellow humans. Be kind. Be caring. Do not worry about tongues.
Dogs primarily cool themselves through panting, not sweating. They have sweat glands on their paw pads, but they are not a main source of cooling like in humans. So, while dogs don't sweat from their tongues, they do use their tongues to help regulate body temperature through panting.
