Only the true ribs are attached to the sternum the false ribs (3) and the floating ribs (2) are not directly attached. The flalse ribs are attached indirectly via cartillage and the floating ribs are not attached at all.
Ribs 8 to 10 are attached individually to the sternum by way of the costal cartilage. Ribs 1 to 7 are attached directly to the sternum, while ribs 11 and 12 are floating ribs without any attachment to the sternum.
Floating ribs (ribs 11 and 12) do not articulate with the sternum directly but are attached only to the thoracic vertebrae in the back. They are considered "floating" because they lack an attachment to the sternum or cartilage.
The upper ribs are not attached to the sacrum. The ribs are connected to the thoracic vertebrae at the back and to the sternum in the front. The sarum or sacrum is a bone at the base of the spine that connects to the pelvic bones.
They are atached to your spine and they make a cage around your organe-to protect them & cover them.
These are called true ribs. They each have their own cartilage connection to the sternum.
The sternum.
Pairs of ribs.
These are called true ribs.True ribs (costae verae) are the first 7 sets of ribs, and they are directly attached to the sternum through the costal cartilage.

If the ribs were not attached to the sternum by cartilage (which is flexible), it would be more difficult to breathe, because as you inhale and exhale the chest needs to be able to flex.

True Ribs...because they're attached to the Sternum
False ribs are connected via costal cartilage
These are called true ribs. They each have their own cartilage connection to the sternum.
Floating ribs are a type of false ribs. False ribs are ribs that do not directly attach to the sternum through cartilage, and they include both floating ribs (ribs 11-12) and ribs 8-10, which are attached to the sternum indirectly through cartilage.
