B. Yellowish vomit
C. Brownish vomit
D. Blackish vomit

Answer 1

Hint:- Bile juice is secreted by liver cells and is temporarily stored and released by the gallbladder. The bile juice is released into the common bile duct and from there into the duodenum. Bile juice contains bile pigments, phospholipids, bile salts, etc. It helps in the digestion of food, especially fat molecules.

Complete step-by-step solution:- Vomiting is the expulsion of stomach contents through the mouth. It usually occurs in the case of indigestion, food poisoning, pregnancy, alcohol consumption, etc. Vomiting is said to be bilious vomiting when the vomiting contains bile juice in large amounts. In human beings, bile juice has a bright yellow color with a greenish tinge. Bile juice contains bile pigments. They are bilirubin and biliverdin. Bilirubin has a yellowish tinge and biliverdin have a greenish coloration. The bile expulsion usually has a yellow coloration as bilirubin is seen in higher amounts in humans and therefore the bilious vomit can be called yellowish vomiting. A bilious vomit can indicate any obstruction in the alimentary canal. Due to the obstruction, bile juice gets accumulated in the intestine part and thus gets vomited. The pH of the bile is about 7.7. Bilious vomiting is common in neonatal. It indicates the intestinal block or obstruction in newborns. In newborns, this is a serious condition and requires sudden treatment. Green vomit also indicates bile expulsion. Brown and black vomiting occur in case of damage to gums, throat, fungal infections occur.
The correct answer is option (A), Yellowish vomit.

Note:-
Bile pigments, bilirubin, and biliverdin are formed by the degradation of heme components from hemoglobin. Bilirubin is seen in the conjugated and unconjugated form. Bile is involved in the digestion of lipids. It activates lipases which are lipid digesting enzymes. It helps in the emulsification of fats by breaking down them into small micelles.
