How does the ribs aid gas exchange?

Explanation: When the diaphragm expands or contracts, the thoracic (chest) cavity expands or contracts, alternately pulling in air (inhalation) or expelling it (exhalation). The ribs, which are flexible, along with the intercostal muscles, help in this process.

What does the rib cage do during inhalation?

When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.

How does the respiratory system work in rats?

Rats are rodents that use their respiratory systems to inhale oxygen. ... The respiratory system is used to inhale oxygen and exhale carbon dioxide. The rodent respiratory system consists of nostrils, lungs, a trachea and a larynx, though the size of these parts varies based on the size of the rodent.

What do the ribs and diaphragm do?

When the lungs inhale, the diaphragm contracts and pulls downward. At the same time, the muscles between the ribs contract and pull upward. This increases the size of the thoracic cavity and decreases the pressure inside. As a result, air rushes in and fills the lungs.

What happens during gas exchange?

During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

What role do the ribs and diaphragm play in changing the diameters?

Definition. One of the most important functions of the ribs and diaphragm is the change in volume of the thorax that helps inspiration and expiration. ... In elevation, this increases the anteroposterior diameter of the thorax.

What is the function of rib cage for Class 5?

The rib cage has three important functions: protection, support and respiration. It encloses and protects the heart and lungs.

What is the function of rib cage Class 6?

The rib cage protects the delicate internal organs like heart, liver and lungs. The rib cage also take part in our breathing movement.

What is the function of the diaphragm in a rat?

The diaphragm, innervated by the phrenic nerves, is the main inspiratory pump muscle and acts in concert with the pharyngeal respiratory muscles to maintain airway patency. More than 20 pharyngeal muscles are involved in respiratory and non-respiratory (swallowing, speech, mastication) functions (Horner 2009).

What is the digestive system of a rat?

The rat stomach was a large, semilunar shaped sac with composite lining. On the stomach was very marked fundus, which formed a blind sac (saccus cecus). The rat liver was divided into six lobes, but without gall bladder. Intestine of the rat was simple, but cecum had a shape as a stomach.

What are the functions of the respiratory system?

Your lungs are part of the respiratory system, a group of organs and tissues that work together to help you breathe. The respiratory system's main job is to move fresh air into your body while removing waste gases.

Why does the rib cage have joints?

The rib cage is semirigid but expansile, able to increase in size. The small joints between the ribs and the vertebrae permit a gliding motion of the ribs on the vertebrae during breathing and other activities.

What are the 3 principles of gas exchange?

Three processes are essential for the transfer of oxygen from the outside air to the blood flowing through the lungs: ventilation, diffusion, and perfusion.

What are the adaptations of alveoli for gas exchange?

Adaptations of the alveoli:

Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through. Extensive blood supply - ensuring oxygen rich blood is taken away from the lungs and carbon dioxide rich blood is taken to the lungs.

Which process helps gas exchange?

Gas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration.
