Rib This article is about the part of the skeleton. For other uses, see Rib (disambiguation). In vertebrate anatomy, ribs (Latin: costae) are the long curved bones which form the rib cage. In most tetrapods, ribs surround the chest, enabling the lungs to expand and thus facilitate breathing by expanding the chest cavity. They serve to protect the lungs, heart, and other internal organs of the thorax.

- 8. The last component of the respiratory system is a muscle structure known as the muscles of respiration. These muscles surround the lungs and allow the inhalation and exhalation of air. The main muscle in this system is known as the diaphragm, a thin sheet of muscle that constitutes the bottom of the thorax.n fact, the system is composed of the following biological structures: nose and nasal cavity, mouth, pharynx, larynx, trachea, bronchi and bronchioles, lungs and the muscles of respiration. (1). A properly functioning respiratory system is a vital part of our good health.

Respiratory System Function The Respiratory System. The function of the human respiratory system is to transport air into the lungs and to facilitate the diffusion of Oxygen into the blood stream. Its also receives waste Carbon Dioxide from the blood and exhales it. The respiratory system consists of the upper and lower respiratory tracts. The upper respiratory tract includes the mouth, nose, nasal cavity, pharynx (wind pipe and food pipe) and larynx or voice box. Each has a specific function to aid the flow of air into the body.

Functions of Respiratory System Organs Larynx. From the pharynx, air enters into the larynx, commonly called the voice box. The larynx is part of the upper respiratory tract that has two main functions: a passageway for air to enter into the lungs, and a source of vocalization.everal organs of the respiratory system are responsible for the process of breathing. The nose, pharynx, larynx, trachea, bronchi, and lungs work together to allow gas exchange to occur at the cellular level.

Diaphragm: Definition & Function Let's look at how the diaphragm carries out this very important function. Function of the Diaphragm The diaphragm is the main respiratory muscle that allows us to inhale and exhale. This is done by the contraction and relaxation of the muscle creating a vacuum that sucks air into our lungs through our mouths and noses.

Diaphragm Diaphragm is a muscular and tendinous sheath that closes the opening between thorax and abdomen and is pierced by structures that pass between these two regions of the body. The diaphragm is the primary muscle of respiration. It is dome shaped and consists of a peripheral muscular part and central tendinous part.The muscular part arises from the margins of the thoracic opening and gets inserted into the central tendon.diaphragm.penings in the diaphragm: All the structures that pass from the thorax into the abdomen or rise from abdomen into the thorax pass through the diaphragm. For this reason, diaphragm contains numerous openings.

The Respiratory System - Structure And Function The respiratory system is the system in the human body that enables us to breathe. The act of breathing includes: inhaling and exhaling air in the body; the absorption of oxygen from the air in order to produce energy; the discharge of carbon dioxide, which is the byproduct of the process.ontraction of the diaphragm muscle – causes the diaphragm to flatten, thus enlarging the chest cavity. Contraction of the rib muscles – causes the ribs to rise, thus increasing the chest volume. The chest cavity expands, thus reducing air pressure and causing air to be passively drawn into the lungs.

Muscles of respiration Along with the diaphragm, the intercostal muscles are one of the most important groups of respiratory muscles. These muscles are attached between the ribs and are important in manipulating the width of the rib cage.There are three layers of intercostal muscles. The external intercostal muscles are most significant in respiration. These have fibres that are angled obliquely downward and forward from rib to rib.n human physiology, the muscles of respiration are those muscles that contribute to inhalation and exhalation, by aiding in the expansion and contraction of the thoracic cavity.

Functions of Respiratory System Organs The primary function of the respiratory system is to allow the lungs to take in atmospheric oxygen through inhalation and dispose of the waste products the body does not need through exhalation. Inhalation is an active motion that causes the diaphragm to contract.

Respiratory System The main function of the bronchi and bronchioles is to carry air from the trachea into the lungs. Smooth muscle tissue in their walls helps to regulate airflow into the lungs. When greater volumes of air are required by the body, such as during exercise, the smooth muscle relaxes to dilate the bronchi and bronchioles.here are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body’s exterior. The lungs...

- Science Videos. Science Main Index. Thoracic cage, or rib cage, protects the heart, lungs and major blood vessels in the chest. The rib cage is made up of 12 pairs of bones forming the cage.Read on to learn more about how the thoracic cage protects the organs in the upper body.ibs also protect parts of the stomach, spleen, and kidneys. The ribs help you to breathe. As you inhale, the muscles in between the ribs lift the rib cage up, allowing the lungs to expand. When you exhale, the rib cage moves down again, squeezing the air out of your lungs.

Muscles of respiration The diaphragm is the major muscle responsible for breathing. It is a thin, dome-shaped muscle that separates the abdominal cavity from the thoracic cavity. During inhalation, the diaphragm contracts, so that it's centre moves caudally (downward) and its edges move rostrally (upward).long with the diaphragm, the intercostal muscles are one of the most important groups of respiratory muscles. These muscles are attached between the ribs and are important in manipulating the width of the rib cage.

What is the function of the ribs and diaphagram in the breathing process? Best Answer: Diaphragm: Expands downwards into the abdominal cavity to allow for the lungs to expand as we inhale. As the diaphragm contracts the air is expelled from the lungs. Ribs: The ribs protect the lungs and expand as you inhale to fascillitate space for the lungs to expand like the diaphragm.The ribs then contract expelling the air in the lungs.Altogether now: The diaphragm relaxes and expands downward into the abdominal cavity as the ribs relax to also expand for an increase in air space for the lungs to take in O2.ibs: The ribs protect the lungs and expand as you inhale to fascillitate space for the lungs to expand like the diaphragm. The ribs then contract expelling the air in the lungs.

The Diaphragm The diaphragm is a double-domed sheet of skeletal muscle, located at the inferior-most aspect of the rib cage. It serves two main functions: Separates the thoracic cavity from the abdominal cavity (the word diaphragm is derived from the Greek ‘diáphragma’, meaning partition). Undergoes contraction and relaxation, altering the volume of the thoracic cavity and the lungs, producing inspiration and expiration.
