Seven pairs are called true ribs. Each rib is attached to the breastbone in the front and curves around to join on to one of the vertebrae that make up the backbone via a strip of costal cartilage.
There are three pairs of false ribs. These are attached to vertebrae but are not linked to the breastbone. Instead, each rib is attached to the rib above it by cartilage.
There are two pairs of floating ribs. These are attached only to the vertebrae of the backbone.
Emulsifies fat, keeping tiny fat droplets suspended in the aqueous contents of the gut
Explanation:
Bile emulsifies fat, keeping tiny fat droplets suspended in the aqueous contents of the gut.
Bile juice is a fluid that is secreted from the liver and stored in the gall bladder. The juice helps in the emulsification of fats or break down of fats into simple fat droplets.
The simple fat droplets from emulsification can then be absorbed in the small intestines through the lacteal.
