The main bones in the abdominal region are the ribs. The rib cage protects vital internal organs. There are 12 pairs of ribs and they attach to the spine.

Vertebral Column, Ribs and Sternum are part of the axial skeleton. The vertebrae provide support for the head and body. All vertebrae have a similar basic design. A solid disc of bone forms the ventral body or centrum.

Solid Organs are the liver, spleen, lungs, kidneys, and the heart. Being solid, they do not contract as actively as the hollow organs.

The rib cage is the arrangement of ribs attached to the vertebral column and sternum in the thorax of most vertebrates, that encloses and protects the heart and lungs.

Humans have 24 ribs, in 12 pairs. All are attached at the back to the thoracic vertebrae, and are numbered from 1–12 according to the vertebrae they attach to. The first rib is attached to thoracic vertebra 1 (T1). At the front of the body most of the ribs are joined by costal cartilages to the sternum.

['Seven ribs which connect directly to the sternum (1-7)', 'Three ribs which connect to the costal cartilages of the rib above (8-10)', 'Two "floating" ribs which connect only at the back (11&12)']

All of your ribs attach to your spine, but only the top seven pairs connect to your sternum. These are known as 'true ribs' and they are connected to your sternum by strips of cartilage. The next three pairs of ribs are known as 'false ribs'.

Most people are born with 12 ribs on each side of the body, making a total of 24 ribs. Some people are born with more than 24 ribs. These extra ribs are called supernumerary ribs. When people are born with less than 24 ribs, it is called agenesis of the ribs.

The ribs form the main structure of the thoracic cage protecting the thoracic organs, however their main function is to aid respiration.

The sternum is attached to the first seven ribs and also to the clavicle, or collarbone. ... Rib pairs one through seven are called 'true ribs' because they connect directly to the sternum with costal cartilage, which are segments of cartilage that help the chest cavity expand during respiration.

The primary divisions of the skeleton system are the head, thorax, and vertebral column. The human cranium supports the structures of the face and forms the brain cavity. The rib cage functions as protection for the vital organs of the chest such as the heart and lungs.

Each rib is a curved, flattened bone that contributes to the wall of the thorax. The ribs articulate posteriorly with the T1–T12 thoracic vertebrae, and most attach anteriorly via their costal cartilages to the sternum. There are 12 pairs of ribs. The ribs are numbered 1–12 in accordance with the thoracic vertebrae.
1030716
The false ribs include both vertebrochondral ribs and vertebral ribs. There are three pairs of vertebrochondral ribs (eighth to tenth) that connect indirectly to the sternum via the costal cartilages of the ribs above them. Their elasticity allows rib cage movement for respiratory activity.

These include the liver and kidneys. The liver is located in the upper right-hand part of the abdominal cavity, under the ribs.

The thoracic cage is formed by the 12 pairs of ribs with their costal cartilages and the sternum. The ribs are attached posteriorly to the 12 thoracic vertebrae and most are anchored anteriorly either directly or indirectly to the sternum. The thoracic cage functions to protect the heart and lungs.

The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax).
