Answer: Venous bleeding
Explanation:
The external bleeding can be define as the bleeding in which the blood leaves the body due to external injury.

Answer:
An asymptomatic carrier
Explanation:
An asymptomatic carrier (healthy carrier or just carrier) is a person or other organism that has become infected with a pathogen, but that displays no signs or symptoms.
Although unaffected by the pathogen, carriers can transmit it to others or develop symptoms in later stages of the disease. Asymptomatic carriers play a critical role in the transmission of common infectious diseases such as typhoid, C. difficile, influenzas, and HIV. While the mechanism of disease-carrying is still unknown, researchers have made progress towards understanding how certain pathogens can remain dormant in a human for a period of time. A better understanding of asymptomatic disease carriers is crucial to the fields of medicine and public health as they work towards mitigating the spread of common infectious diseases.
