Inside each new seed there is a tiny plant embryo which looks like a tiny stem and leaves tucked into a kind of fetal position. The seed also contains enough nutrition for the new plant to use until it sprouts and begins to manufacture its own food by photosynthesis.
Infections are the most common causes of coughing up blood. They account for 60 to 70 percent cases of all haemoptysis. Infections may be caused by invasive bacteria such as Staphylococcus aureus and Pseudomonas aeruginosa or fungi such as Aspergillus species. Viruses such as influenza may cause severe hemoptysis.
Blood can also drip back into the throat or down into the stomach, causing a person to spit or even vomit blood. Signs of excessive blood loss include dizziness, light-headedness, confusion, and fainting. Excessive blood loss from nosebleeds is rare.
