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.
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.
Oxygen is picked up by the blood when it is at 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.
Go to the hospital as quickly as possible!
Of course not!
yes
The blood picks up oxygen in the lungs and gives it to all the organs in the body that needs it.
If there is blood in the lungs... well, we breath air from our lungs, we cough and what is in our lungs comes out. We usually cough due to something unknown being in our lungs and our lungs forcing it out. So, yes when we cough and there is blood in our lungs, blood will come out. Now if we are to breath in blood for some unknown stupid reason, we will cough it out. So yes, if there is internal bleeding in our lungs, we will cough up blood.
Blood with no oxygen (the blood that flows to the heart picks up oxygen from the lungs).
