Virtual Body Circulation, Respiration, Breathing

Answer 2: The respiratory system functions in the exchange of gases with the outside environment. Oxygen is inhaled through the nasal cavity or the mouth, and it travels to the alveoli in the lungs. There, the capillaries exchange the oxygen for carbon dioxide. The oxygenated blood flows back to the heart from the lungs. It enters the left side of the heart and is delivered to all the body tissues via the aorta. In the capillaries of the body tissues, oxygen is exchanged for carbon dioxide. This deoxygenated blood flows back to the right side of the heart and then to the lung. In the capillaries that run across the alveoli, carbon dioxide is exchanged for oxygen that has recently been inhaled. The carbon dioxide will then be exhaled through the mouth and nasal cavity.

During exercise the residual volume increases as the breaths become shorter and faster, leaving more air in the lungs. Gas exchange Gas exchange occurs within two different places in the body, the alveoli and the muscles. In the Alveoli, the exchange of Carbon Dioxide and Oxygen takes place. When inspiration occurs, the oxygen you take in diffuses through the walls of the Alveoli into the red blood cells, when the oxygen is in the red blood cells, it gets transported around the body to the different tissues.

The circulatory system brings in the oxygen that then the lungs take in and transport it around the body and then brings the carbon dioxide back for the lungs to push out(exhale) The lungs bring oxygen into the blood stream which goes to feed the heart and the rest of your body. The respiratory system brings in oxygen, which then the circulatory

The complexity of the respiratory system and the physiology behind pulmonary respiration can be considered extraordinary high. Within the single system, individual organs, actions and co-ordinations are culminated to equate in the survival of humans. The respiratory system carries out many roles within the body; control of bodily pH, aid in speech production and olfaction, regulation of blood pressure and promotion of venous and lymphatic flow. Although these function are necessary to optimally function, the exchange of gases from the internal bodily environment to the external bodily environment is the most important function and role of the respiratory system (Martini, Ober, Nath 2011).

During expiration, the diaphragm and all of the surrounding muscles relax. This allows the chest cavity to return to its original volume.

The diaphragm contracts when the ribcage moves up. The diaphragm relaxes when the ribcage move downs. Task 3 Describe the role of the following in relation to the respiratory system • Muscles • Blood • Nervous system Muscles Muscles control the process of inhaling and exhaling. The intercostal muscles contract and move the ribcage up and out while the diaphragm contracts, this increases the pressure inside the thoracic cavity which causes oxygen to drawn in. when the intercostal muscles relax and move the ribcage down and in and the diaphragm relaxes, this decreases the pressure inside the thoracic cavity which expels the carbon dioxide.

The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).

The right side of the heart, has the right atrium and ventricle where blood exchanges its oxygen and nutrient for the waste material of the cells and then returned to right side of the heart.

The Respiratory system is an integrated system of organs involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. Your Respiratory system is made up of the organs in your body that help you breathe. The Respiratory system is the system of the body that deals with breathing. The trachea is a wind pipe. The trachea is a pipe shaped by rings of cartillage. A Bronchi are two tubes that carry air into the lungs. The Respiratory system consistes of many different organs. The organs are the lungs, trachea, bronchi, alveoli, diaphragm, nose, mouth, and pharynx. In the Respiratory system the right lung is larger and has more lobes that the left lung becuase the heart is normally located on the left side, and takes up space where the lung would had been. The functions 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 is also used for the of exchange gases. The importance of the Respiratory system is that it allows for the exchange of gases; meaning carbon dioxide and oxygen. These gas exchanges occur in the alveoli's and the capillaries. This gas exchange of gases is the Respiratory system's means of getting oxygen to the blood. The goal of breathing is to

Exhalation, (breathing out), is the opposite of inhalation and occurs when the inspiratory muscles relax causing the diaphragm to depress which decreases the lung volume. This decrease in volume causes the alveolar pressure to increase therefore the carbon dioxide in the lungs flows from a high pressure to a lower pressure in the atmosphere. (Tortora & Derrickson, 2011)

Inspiration is when the diaphragm contracts and the thorax expands allowing air to enter the lung. When this happens the alveolar volume increases and causes a decrease in alveolar pressure below barometric air pressure and air flows into the lungs. Alveolar pressure is the pressure in centimeters of water pressure (cm H2O) retained in the alveoli of the lungs during inspiration. Barometric pressure, is the pressure applied to by the weight of air in the atmosphere of Earth. At the end on inspiration the diaphragm stops contracting and the alveolar pressure becomes equal to barometric air pressure and no more movement of air occurs. During expiration, the diaphragm relaxes and the thorax decreases resulting in a decrease in alveolar volume

Gas exchange is when oxygen is delivered from the lungs to the blood stream and carbon dioxide is taken out of the bloodstream and into the lungs. Gas exchange occurs within the lungs between the alveoli and capillaries which are in the walls of the alveoli. The walls of the alveoli share a membrane with the capillaries in which oxygen and carbon dioxide move freely between the respiratory system and the bloodstream. Oxygen molecules attach to red blood cells, which travel back to the heart. At the same time, the carbon dioxide in the alveoli are exhaled out of the body.

The respiratory system, also known as the ventilatory system, is a series of organs found in the human body. The system’s primary function is performing respiration – inhaling oxygen from the environment and exhaling carbon dioxide out of the body (K.M Zimmermann, 2016). Oxygen acts as fuel – without it, the body would be unable to function. Carbon dioxide, the by-product of this process, is breathed out as it is toxic to the human body when it builds up (A.M Helminstine, 2016).

The respiratory system is the process responsible for the transportation and exchange of gases into and out of the human body. As we breath in, oxygen in the air containing oxygen is drawn into the lungs through a series of air pipes known as the airway and into the lungs. As air is drawn into the lungs and waste gas excreted, it passes through the airway, first through the mouth or nose and through the pharynx, larynx and windpipe – also known as the trachea. At this point it then enters the lungs through the bronchi before finally reaching the air sacs known as alveoli. Within the lungs, through a process known as diffusion, the oxygen is transferred to the blood stream through the alveoli (air ducts) where it is then transported inside

     The air we inhale enters the lungs through tubes called bronchi. These branch into the smaller brochioles and finally into tiny air sacs, the aveoli. The average lung has more that 300 million of these air sacs, which provides a combined area of more than 750 square feet for oxygen to be absorbed into the bloodstream and carbon dioxide to be expelled.
