posibly, depending on the circumstances.
You cant
Not in humans. Some animals and fish can regenerate their teeth.

Pulmonary veins
You probably mean what do veins do? Anyways, they always return blood back to the heart.
There are four main types of veins that pigs and humans have in common. These include the pulmonary, systemic, deep, and superficial veins.
they are found in humans and in plants and they generate different cells or even regenerate a whole original organ
Yes you do 10 infact
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.
Currently humans cannot regenerate at all
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.
