The shape of the nose and hair follicles are structural adaptations in the nasal cavity that allow it to carry out its functions. Mucous is also an adaptation needed to carry out the functions in the nasal cavity.
Structural and Behavioral
Allow air to pass from trachea to lungs
The main function of a pig's trachea is to breathe. It is part of system of passages that allow air into the lungs.
* Nose* Pharynx* Larynx* Trachea* Bronchi* Lungs
The cactus has a number of structural adaptations that allow it to live in the harsh conditions of the desert. Many other plants lack these adaptations and cannot survive in a desert.
Alligators have many adaptations that allow them to be some of the fiercest hunters. Their adaptations include teeth, skin, webbed feet, ability to hold their breath, and their eyes.
Yes, the C-shaped cartilage rings maintain the openness of the trachea. The rings provide structural support to the trachea, preventing it from collapsing and maintaining its shape. The open ends of the C-shape allow for flexibility during movement, such as swallowing or bending of the neck.
they hold the trachea open, otherwise it would be squeezed flat like the esophagus when it is empty. the trachea also has bands of smooth muscle that allow the esophagus to expand into the trachea when swallowing. this is why you cant breathe and swallow at the same time.
Longitudinal elastic fibers enable the trachea to stretch and descend with the roots of the lungs during inspiration.
The cartilage rings in the trachea prevent the trachea from collapsing during absence of air and also protect it.These cartilagenous ring are C shaped and are meant for particular purposes such as:they give support and strength to the tracheathey prevent from collapsing and breakingalso cartilage contain much collagen fibres which are stress resistantthey don't allow the trachea to shrink
it helps to prevent trachea from collapsing by maintaining definite shape
The function of the red blood cell is to carry oxygen to body tissues. Its structural features that allow this include the hemoglobin molecule, its anuclear state, and its biconcave shape.
