Final answer:
Albumin, the most abundant plasma protein, regulates bodily fluid levels by maintaining osmotic balance and acting as a transport vehicle for fatty acids and hormones.
Step-by-step explanation:
The function of albumin present in the blood is to regulate the amount of fluid in the body. Albumin, which is the most abundant plasma protein, is crucial for maintaining the osmotic balance. By contributing to the osmotic pressure of blood, albumin holds water within the blood vessels and helps to maintain both blood volume and blood pressure. Albumin also acts as a transport molecule for various substances, including fatty acids, hormones, and other hydrophobic molecules, by binding to them and facilitating their solubility in the plasma.
