A:
This passage is only found in Luke's Gospel (Luke 22:44): "And being in an agony he prayed more earnestly: and his sweat was as it were great drops of blood falling down to the ground." It supposedly took place while Jesus was praying alone in the Garden of Gethsemene and the disciples were asleep some way off.
The passage is ambiguous as to whether Jesus sweated actual blood, or drops of sweat that simply looked like blood. Clearly, there was no witness to this, and it is not told in any of the other gospels. Moreover, scholars have now established that Luke's Gospel was substantially based on Mark's Gospel, so the reference to Jesus sweating blood, or like blood, is an embellishment intended to impress Luke's original audience. No one saw Jesus sweat blood.
No you head does not expand this is not physically possible. It may feel like it because of all the blood ruhsing through you body and your heart beating so fast. When you sweat alot this is to cool down you body. There is no way your head could expand because of your heart beating faster and sweating.
It could cause an infection which can damage a tattoo. If you have to sweat after getting a tattoo then clean it when you're done sweating.
Because it gets hot, then the sweat glands send out the sweat, which causes it to cool down.
During warmer weather, the blood vessels at the surface of the skin dilate. At the same time, our skin produces sweat, which evaporates - taking the excess heat into the atmosphere.
They have no sweat glands. Rabbits cool themselves by circulating blood thru the veins in their large ears. Rabbits do not pant to cool themselves either. If they are panting they are in distress. A frozen water bottle, dasani, nestle, etc. placed in their cage so they can lie down on/beside it will help them cool themselves.
Jesus in Gethsemane.
Yeah, Luke 22:44
When he was in the Garden of Gethsemane. Luke 22:39-44
blood, sweat, rotting flesh
no.a book named A Case of Christ by Lee Strobel explained that because of severe tensions and nervousness of Jesus as he faced death, he sweated and some small veins (can we say) blew up. it's just a tiny amount of blood mixed with sweat.

Although this medical condition is relatively rare, according to Dr. Frederick Zugibe (Chief Medical Examiner of Rockland County, New York) it is well-known, and there have been many cases of it. The clinical term is "hematohidrosis." "Around the sweat glands, there are multiple blood vessels in a net-like form." Under the pressure of great stress the vessels constrict. Then as the anxiety passes "the blood vessels dilate to the point of rupture. The blood goes into the sweat glands." As the sweat glands are producing a lot of sweat, it pushes the blood to the surface - coming out as droplets of blood mixed with sweat. So the reason why Jesus was sweating blood is that He was under a lot of stress. Read Luke 22.

Jesus sweat blood while praying because of the anguish he felt over this impending death. When someone sweats blood, it's called hematidrosis. Extreme stress can cause tiny capillaries in the sweat glands to rupture and this causes sweat and blood to mix. This makes the skin extremely sensitive and so Jesus would have felt even more pain than normal when he was beaten before his crucifixion.

(Also, the book The Case for Christ does an excellent job at explaining what the crucifixion would have been like for Jesus pp.258-267.)
No. Sweat is produced by specialized glands in the skin and is distinct from the blood in your cardiovascular system.
Pigs actually don't sweat blood, they have glands that produce a red-colored secretion that acts as a sunscreen and inhibits bacterial growth on the skin. This secretion is often mistaken for blood, giving rise to the misconception that pigs sweat blood.
In hot weather - blood vessels dilate (widen) - to allow the exchange of heat between the blood and sweat glands. The sweat evaporates - cooling the blood.
