No blood does not come from the brain. It comes from the heart. It is pumped and some is sent to the brain and other parts of the body.
Your blood stream carries them.
Yes it has come to a head the blood comes out with the infection. When there is only blood coming out. Put antibiotic ointment and a band aid. That means most of the infection is gone
The two most likely reasons would be trauma or infection. This is not normal and should be evaluated by a veterinarian because it can be a sign of serious internal problems.
A high white blood cell count usually indicates that an infection is present. White blood cells protect the body against infection by eating viruses.
the development of blood clots that may come loose and block the arteries, excessive loss of blood, and infection
Taking oxycodone would not cause blood to come from your penis. It is more likely that you either have an infection or trauma to the area. In either case you should seek the help of a doctor who can examine you and give you the propper treatment.
I would suspect a bladder infection.
No. Milk is not pus, it is more similar in content to blood or sweat, but it does not have the harmful bacteria nor dead white blood cells and other infection-fighting cells and "organisms" that is found in pus. Pus is the result from infection, and is not healthy to come in contact with nor consume. Milk is not from an infection. If it was, the calves that subsist off of milk or other baby mammals that rely on their mother's milk to survive would die very quickly. Mammals would never exist. Humans, which are mammals, would never exist.

If your white blood cell count is high, this shows an infection, usually bacterial. If your neutrophil count is also high, this shows an acute infection, whereas if your macrophage count were to be high, this would show a chronic infection. An acute infection or inflammation means that it has had a duration of usually less than 2 weeks. A chronic infection lasts longer than 2 weeks. The difference is that the neutrophils are the first responders to inflammation and infection, then come the macrophages. The neutrophils have a shorter lifespan and the macrophages can live for a long time fighting infection. This is how you get the higher count of neutrophils with an acute infection, and the higher macrophages with chronic infection.
Blood plays a crucial, fundamental role in the human body. For such a complex organism such as ourselves, lack of a bloodstream would end in...death, I'm sad to say. Blood carries hormones, nutrients, oxygen, as well as waste products of metabolism. The white blood cells in the blood are there to fend off infection, so without them, our immune system would come to a halt, leaving us open to disease and illness.
