what is the function of the ribs in the respiratory system?

The human rib cage is a component of the human respiratory system. It encloses the thoracic cavity, which contains the lungs. An inhalation is accomplished when the muscular diaphragm, at the floor of the thoracic cavity, contracts and flattens, while the contraction of intercostal muscles lift the rib cage up and out.

The chest wall consists of the muscles of respiration—such as the diaphragm, the intercostal muscles, and the abdominal muscles—and the rib cage. The functions of the respiratory system include gas exchange, acid-base balance, phonation, pulmonary defense and metabolism, and the handling of bioactive materials.

The costal cartilage are segments of cartilage that connect the sternum to the ribs and help to extend the ribs into a forward motion. This cartilage also contributes to elasticity within the walls of the thorax, allowing the chest to expand during respiration. There are twelve costal cartilage sections.

The primary functions of the skeletal system are locomotion, support of the body, and the protection of internal organs such as the brain, heart, and lungs.

When they expand, they pull air into the body. When they compress, they expel carbon dioxide, a waste gas that bodies produce. Lungs do not have muscles to pump air in and out, though. The diaphragm and rib cage essentially pump the lungs.

functions: separates the abdominal and thoracic cavities and it draws air into the lungs. function: pumping chambers of the heart; the right side pumping oxygen-poor blood to the lungs and the left side pumping oxygen-rich blood to the body.

Lung function. The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood.

The last two pairs of ribs are called 'floating ribs'. These only attach to your spine. Your ribs form a protective cage that encloses many of your delicate internal organs, such as your heart and lungs.

This arrangement means there is a fast efficient transfer of oxygen and carbon dioxide between the blood and the air, the major function of the respiratory portion. The terminal bronchioles branch to give rise to respiratory bronchioles, which lead to alveolar ducts, alveolar sacs and alveoli.

The ribs are the bony framework of the thoracic cavity. The ribs form the main structure of the thoracic cage protecting the thoracic organs, however their main function is to aid respiration. There are twelve pairs of ribs. Each rib articulates posteriorly with two thoracic vertebrae by the costovertebral joint.

The rib cage surrounds the lungs and the heart, serving as an important means of bony protection for these vital organs.In total, the rib cage consists of the 12 thoracic vertebrae and the 24 ribs, in addition to the sternum.

The lower respiratory system, or lower respiratory tract, consists of the trachea, the bronchi and bronchioles, and the alveoli, which make up the lungs. These structures pull in air from the upper respiratory system, absorb the oxygen, and release carbon dioxide in exchange.

The mechanism of taking air into the lungs is however sligthly different than in humans. Frogs do not have ribs nor a diaphragm, which in humans helps serve in expand the chest and thereby decreasing the pressure in the lungs allowing outside air to flow in.

The lungs are located within the chest cavity, most of which is contained within the rib cage.

The bones of the chest — namely the rib cage and spine — protect vital organs from injury, and also provide structural support for the body. The rib cage is one of the body's best defenses against injury from impact. Flexible yet strong, the rib cage protects major vital organs such as the heart, lungs, and liver.

The human rib cage is a component of the human respiratory system. It encloses the thoracic cavity, which contains the lungs. ... When the external intercostal muscles contract and lift the ribs, the upper ribs are able also to push the sternum up and out.
