What is the meaning of trachea in respiratory system?
The trachea is a passage that enables air to travel between the Oral and Nasal cavities into the Bronchus, in order to reach the lungs. The trachea is supported by cartilage that keeps it open, however the rings are not complete (except for the Cricoid Cartilage) which allows for flexibility.
Structure of trachea?
Structure of the tracheaThe trachea is lined by cartilage and divided into two branches. These two branches are called the bronchi. The left bronchus enters the left lung and the right bronchus enters the right lung. Each bronchus is further divided into around 25 smaller branches. These smaller divisions of bronchi are known as the bronchioles. The bronchioles carry air into the alveoli.
What is the pad in the vertebrae that allows limited movement?
Cartilage
Cartilage that includes the hip knee and elbow?
This cartilage is called hyaline cartilage because it is like glass and very smooth. It allows for easy movement in the joint.
Is cartilage in your bones?
There is cartilage at the ends of the bones. Some allows for free movement, some for limited movement and some for no movement.
What is the role of cartilage in the spinal column?
Cartilage between the bones allows them to move easily and comfortably without the bones rubbing
What is the the importance of cartilage?
Costal cartilage allows more ribs to attach to the sternum, albeit indirectly, for a more stable and secure ribcage to protect the heart and lungs.

What covers the ends of bones in adults?
The ends of bones in adults are covered with cartilage. Cartilage is a tough yet flexible tissue that helps to protect bones and allows them to move more freely where bone meets bone (a joint). There are different types of cartilage in the body. The cartilage that covers the ends of bones at a joint is known as articular cartilage, a specific type of hyaline cartilage.
What structure allows bones to grow in thickness?
Bones grow in length by endochondral ossification. It begins with cartilage that acts like a model of the bone that will grow. The bone grows in length and diameter(appositional). the structure that allows this is the epiphyseal cartilage that seperates the epiphysis from the diaphysis. When the bone is fully grown this cartilage will become bone and simply the epiphyseal line.
Does a great white shark have cartilage?
Yes because it replaces the bone and allows it to be more flexible
Why is it important to have cartilage around the end of bone?
Allows joints to move smoothly and without friction.
