49
Hematemesis
The vomiting of blood
50
Hemorrhage
The escape of blood from the vessels; bleeding. Small hemorrhages are classified by size as: petechiae (very small); purpura (up to one cm.), and ecchymoses (larger; bruises, black eye, etc). Accumulation of blood within a tissue is called a hematoma
51

Pertaining to the liver
52

53

An abnormally low content of albumin in the blood

56
Ileum
The distal portion of the small intestine, extending from the jejunum to the cecum
57
Interferon
Proteins produced by the cells of the immune system in response to a challenge by foreign agents (viruses, bacteria, etc.) Interferons are an important component of anti-viral response and interferon-alpha is used in the treatment of Hepatitis C. Pegylated interferon is interferon-alpha to which polyethylene glycol is added to make the interferon last longer in the body
58
Intestine
Bowel, the digestive tube passing from the stomach to the anus. It is divided primarily into the small and large intestine

Resistant to cure, relief, or control
60

Surgery done through small incisions, using cameras and video monitors to guide the surgical instruments
64
Liver

Oncotic Pressure
In blood plasma, the dissolved compounds have an osmotic pressure. A small portion of this pressure is related to the presence of large protein molecules (particularly albumin). The presence of these large proteins prevents fluids from leaking through capillary walls. If plasma proteins are reduced, edema can result. Hence, edema is seen in liver disease due to the low levels of serum albumin.

Those signs, symptoms, and findings which indicate that a disease or disorder is affecting the body as a whole
