Why dolphins need a liver?

Dolphins, like all mammals, need a liver for a variety of vital functions:

1. Detoxification: The liver filters the blood, removing toxins and waste products from the body. This is especially important for dolphins as they live in an aquatic environment, where they might encounter harmful substances.

2. Protein Metabolism: The liver plays a crucial role in protein synthesis, breaking down proteins into amino acids and converting them into new proteins needed for growth and repair.

3. Bile Production: The liver produces bile, which is essential for digesting fats. This is vital for dolphins who rely on fish and other marine organisms for their diet.

4. Glucose Regulation: The liver helps regulate blood sugar levels by storing excess glucose as glycogen and releasing it when needed.

5. Blood Clotting: The liver produces clotting factors, which are essential for stopping bleeding.

6. Storage of Vitamins and Minerals: The liver acts as a storage site for essential vitamins and minerals, like vitamin A, vitamin D, and iron.

7. Immune Function: The liver is an important part of the immune system, producing immune cells and proteins that help fight infections.

In short, the liver is a vital organ for dolphins and all mammals, playing a crucial role in numerous essential bodily functions.
