you had a clotted nosebleed, injured An internal organ or vommited too much Depends on where the blood came from. If the blood comes from a nosebleed, it means you have a contusion in your nose, and you're bleeding down into your mouth. This could also indicate bleeding gums, or lacerations in the mouth or throat. You use the term spitting up. If you mean vomiiting blood, you're discussing a hemorrhage -- and this one requires a 911 call (possibilities include upper or lower gastric hemorrhage, esophageal varices, and other conditions). If you mean coughing up blood, this could indicate an insult to the lungs -- a visit to the hospital is called for now. If the bleeding is copious, call 911. A little more information would go a long way in helping me answer this.
IT means you should go and see a qualified medical practitioner (a doctor) and get yourself checked out.
If you spit up blood you need medical treatment as soon as possible.
Could be several. Lung cancer is one. However, tuberculosis is probably most likely as it causes the rupture of blood vessels in the lungs, therefore, spitting up blood.
I hate to be the bearer of bad news, but most likely yes.
Oxygen is picked up by the blood when it is at the lungs.
I think you mean picked up. It is the lungs.
serious issue my friend
Yes, go to the doctor and he will tell you what to do next. Spitting blood is a problem.
Lungs contain lots of blood. Blood goes to the lungs to pick up oxygen.
yes
Go to the hospital as quickly as possible!
Of course not!
The blood picks up oxygen in the lungs and gives it to all the organs in the body that needs it.
