Step-by-step explanation:
The term meaning spitting blood or blood sprained spectum is hemoptysis.
Hemoptysis is the medical term used to describe the act of coughing up blood or blood-stained sputum from the respiratory tract. It can be caused by various conditions such as bronchitis, tuberculosis, lung cancer, or even a simple nosebleed that is swallowed and then coughed up.
For example, if a person has a severe respiratory infection, such as pneumonia, the infection can cause damage to the bronchial lining, leading to bleeding and the presence of blood in the sputum.
