THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The most important bile pigment, bilirubin, is made when red blood cells are broken down in the liver. Bilirubin is what makes urine yellow and stool brown. Bile salts break down larger fat globules in food into small droplets of fat.

Detailed explanation-2: -Fats or lipids are broken down in the liver for use as energy. They are then moved to fat tissue. More than 90% of body energy is stored here and is the main source of fuel storage for the body. Fats are insoluble in blood and water and so the liver produces special, fat-carrying proteins called lipoproteins.

Detailed explanation-3: -Bile is important for the breakdown and absorption of fats.

Detailed explanation-4: -The liver filters toxins through the sinusoid channels, which are lined with immune cells called Kupffer cells. These engulf the toxin, digest it and excrete it. This process is called phagocytosis. As most chemicals are relatively new it will be thousands of years before our body properly adapts to them.
