The cartilage between the ribs and breastbone moves and flexes when you breathe.
The cartilage between your ribs and breastbone allows for flexibility and movement of the ribcage during breathing. As you inhale, the cartilage expands and stretches, while it contracts and returns to its original position when you exhale. This movement helps to accommodate the expansion and contraction of the chest cavity during breathing.
it poops or pees
The reason there are discs of cartilage between the bones in the vertebral column is because it is to cushion the vertebrae from grinding against each other, which is what happens when arthritis/age sets in, causing the discs of cartilage to erode and letting the vertebrae grind against each other/crush the spinal cord, causing pain and/or paralysis
The trachea is supported by C-shaped rings of cartilage. The point at which there is no cartilage is where the trachea is in contact with the oesophagus. As a large bolus of food passes down the oesophagus the elastic walls expand to accommodate it. This is made possible by the absence of cartilage on the trachea. However, the trachea is prevented from collapsing due to the supporting cartilage around the rest of it.
if bacterias enter in our lungs so we can't breathe properly
Photosystem I or the p700 complex is used last in photosynthesis.
as you grew, most of your cartilage was replaced by bone.
you breathe in and out
the lungs will moves down when breathe out air

There are no bones in your ears, just cartilage and cartalige clicks sometimes because there is air between your caralige in your ear and if your pull on it the air and the cartilage are meeting making a click in your ear.
