19. Respiratory and Excretory System Figure above shows many of the structures of the respiratory system. Each of the parts has a specific job. The parts of the respiratory system include the following: The diaphragm is a sheet of muscle that spreads across the bottom of the rib cage. When the diaphragm contracts, the chest volume gets larger and the lungs take in air.

What does the respiratory system do? The primary function of the respiratory system is to supply the  blood with oxygen in order for the blood to deliver oxygen to all  parts of the body. The respiratory system … does this through  breathing. When we breathe, we inhale oxygen and exhale carbon  dioxide.his exchange of gases is the respiratory system's means  of getting oxygen to the blood. The respiratory system also helps  to regulate the acid-base level in the blood. lastly, the  respiratory system allows us to vocalize by the movement of exhaled  air through the larynx.

Anatomy Of The Respiratory System 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.. The nose and nasal cavity constitute the main external opening of the respiratory system. They represent the entryway to the respiratory tract – a passage through the body which air uses for travel in order to reach the lungs.

- 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.

How the Lungs and Respiratory System Work The Diaphragm's Role in Breathing. Inhalation and exhalation are the processes by which the body brings in oxygen and expels carbon dioxide. The breathing process is aided by a large dome-shaped muscle under the lungs called the diaphragm.

Thoracic diaphragm The diaphragm separates the thoracic cavity containing the heart and lungs, from the abdominal cavity and performs an important function in respiration: as the diaphragm contracts, the volume of the thoracic cavity increases and air is drawn into the lungs.he diaphragm functions in breathing. During inhalation, the diaphragm contracts and moves in the inferior direction, thus enlarging the volume of the thoracic cavity (the external intercostal muscles also participate in this enlargement).

- Information from these sensors is conveyed along nerves to the respiratory center in the brain stem. From the respiratory center the skeletal muscles of ventilation, in particular the diaphragm, are alternately activated to cause air to move in and out of the lungs.

- (Answer #1). The respiratory system includes structures such as the mouth, nose, trachea, lungs and the muscular diaphragm. The main purpose of the respiratory system is to draw air into the lungs, where oxygen can be harvested and incorporated into the blood for delivery to the rest of the body.It also functions to remove waste products, such as carbon dioxide, that collect from metabolism.any diseases affect our breathing, such as emphysema, which is a disease that makes gas exchange within the lungs very difficult and breathing to become labored. Bronchitis causes inflammation and mucous production, inducing fits of coughing.

Diaphragm (Human Thorax) Location, Anatomy, Function and Position The main function of the diaphragm is as a muscle of respiration, meaning that it aids with breathing. It is aided by other muscles and accessory muscles of breathing when a person experiences shortness of breath. When the diaphragm contracts, the lungs expand and air is inhaled.t is a flat sheet of muscle that is responsible for breathing. The diaphragm essentially pulls and pushes against the lung causing it to expand with inhalation and contract with exhalation. The thoracic diaphragm also separates the organs in the thoracic cavity (chest) and abdominal (belly).

Respiratory System Muscles of Respiration. Surrounding the lungs are sets of muscles that are able to cause air to be inhaled or exhaled from the lungs. The principal muscle of respiration in the human body is the diaphragm, a thin sheet of skeletal muscle that forms the floor of the thorax.he airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body’s exterior. The lungs... Click to read more below. The cells of the human body require a constant stream of oxygen to stay alive.

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.

How Does the Cardiovascular System Work With the Respiratory System? The other part of the respiratory system is the muscles, such as the intercostals (muscles between the ribs) and the diaphragm, which cause the lungs to expand and contract. When the size of the lungs changes, so does the pressure inside, leading to air either coming in (inhalation) or being forced out (exhalation).

What are the similarities and differences between a bird and humans respitory system and breathing methods? Birds do not have a diaphragm; instead, air is moved in and out of the respiratory system through pressure changes in the air sacs. Muscles in the chest cause the sternum to be pushed outward. This creates a negative pressure in the air sacs, causing air to enter the respiratory system.

Thoracic diaphragm The diaphragm separates the thoracic cavity containing the heart and lungs, from the abdominal cavity and performs an important function in respiration: as the diaphragm contracts, the volume of the thoracic cavity increases and air is drawn into the lungs.hen the lower ribs are stabilized and the central tendon of the diaphragm is mobile, a contraction brings the insertion (central tendon) towards the origins and pushes the lower cavity towards the pelvis, allowing the thoracic cavity to expand downward. This is often called belly breathing.

Bronchioles: Definition & Function The respiratory system consists of a pair of lungs and a trachea through which we draw in air. Air pressure of the atmosphere forces the air inside. For this to happen, the body must lower air pressure inside the chest cavity. It does this by expanding the cavity, using muscles in the rib cage and a special muscle called a diaphragm located under the lungs. When we breathe, the air is first drawn in through the mouth and nose. Moving downward, it goes through the pharynx (or the throat) and through the larynx (or the voice box). From there, it enters the main airway called the trachea. The trachea has rings of cartilage supporting it. The trachea branches off into two bronchi, one for each lung.

Medical Definition of Diaphragm (muscle) Diaphragm (muscle): The muscle that separates the chest (thoracic) cavity from the abdomen. The diaphragm is the main muscle of respiration. Contraction of the diaphragm muscle expands the lungs during inspiration when one is breathing air in.We rely heavily on the diaphragm for our respiratory function so that when the diaphragm is impaired, it can compromise our breathing.ontraction of the diaphragm muscle expands the lungs during inspiration when one is breathing air in.
