• This is different from ordinary oxygen, which has the chemical formula O2.

Explanation

Plasma, the liquid component of blood, is composed of approximately 90% water.

This high water content helps transport nutrients, hormones, and waste products throughout the body.

Explanation

Bile is produced by the liver and stored in the gallbladder.

It is important for the digestion and absorption of fats in the small intestine.

Explanation

Insulin is produced by the pancreas, which is an organ located behind the stomach.

The pancreas contains clusters of cells called the Islets of Langerhans, specifically the beta cells within these islets, which are responsible for producing insulin.

Insulin plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose into cells for energy production or storage.

When blood sugar levels rise after a meal, the pancreas releases insulin to help lower blood sugar levels by promoting the uptake of glucose into cells.
