The respiratory system consists of different structures that all function together to deliver oxygen to the lungs and expel carbon dioxide from the body. The respiratory system consists of structures such as the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, alveoli and the lungs. The primary function of the respiratory system is gas exchange but other functions also include sound production, assistance in abdominal compression, and coughing and sneezing. The lungs are the main organ of the respiratory system. The function of the lungs receiving the oxygen from the air we breathe and delivering the oxygen to the red blood cells contained in the blood. Red blood cells carry oxygen around the body to make sure the whole body is …show more content…
The bronchi deliver the oxygen to the lungs to allow for proper oxygenation. The respiratory system is an important system to the body, it transports and exchanges gasses that are important for the body. Sometimes conditions or diseases can affect the important structures in the respiratory system causing breathing or respiratory problems.Most respiratory system conditions or disease can be held under control with medication. Asthma is a respiratory condition that affects 1 in 10 people and can either be severe or minor. Asthma is defined as episodes of coughing, wheezing and chest tightness, which can happen all at the same time or at separate times. There are a few different types of asthma, for example, allergic asthma and sports induced asthma. Allergic asthma is known as, inflammation as an immune response. In allergic asthma inflammation in the airways is constant even when the patient is not having any symptoms. The triggers of allergic asthma can be, dust mites, cockroaches, cats, dogs, and fungi. Since the walls of the airways are thickened already because of the inflammation, when the bronchospasms occur the airways get …show more content…
The walls of the bronchioles thicken, become enlarged and they tighten up. The structure in the bronchioles causing the airway to tighten up is the elastic fiber and smooth muscle. They constrict making it very difficult for a patient to be able to take in air. This makes the process of oxygenation hard because very little oxygen is being able to reach the alveoli. The reasoning for bronchiole constriction during asthma can be a number of things, but the bronchioles usually rapidly constrict when they come in contact with the substance. For example during allergic asthma bronchioles can constrict when airways come in contact with allergens, such as if someone is allergic to dogs and they come in close contact with a dog. The hyperresponsiveness of the bronchioles is a sensitivity to stimuli. The symptoms patients acquire when suffering from asthma can be, coughing, chest tightness and, shortness of breath. When a person coughs when having asthma the coughing comes from the person feeling as though something is obstructing their airways. They cough to try to help clear their airways. The wheezing a person experiences comes from when the bronchioles are constricted and it makes it difficult to breathe the closed up airways causes a whistling noise occur when you breathe out. Chest tightness during asthma happens because in the lungs there are no nociceptors. The lack of
Asthma is a long-term lung disease. Those with asthma have sensitive airways in their lungs which triggers a flare up. When this flare up happens the muscle around the airways squeeze tight and the airways swell, become narrows and produce more mucus. (Anon., 2016) All these things make it harder for a person to breathe. Asthma effects the human body’s respiratory system. Asthma causes a spasm and constriction of the bronchial passages and the swelling and the inflammation of the mucous lining. The body responds by defence cells from the immune system, which causes the airways to swell and the muscles surrounding the airways to contract. Which is what cuts off the airflow. While a person is in asthma attack, the asthmatic cannot breathe which
The circulatory system would transport nutrients and oxygen to all the cells in the body. Organs include, heart, veins, and arteries. The respiratory system exchanges gases, like carbon dioxide, and oxygen so that the body will function properly. These two systems work together to get oxygen to move blood, to work out many organs in the body. Air goes in and out by the mouth or nose and comes in and out of the lungs. What comes in is oxygen, and that oxygen moves blood to the lungs. What comes out is carbon dioxide, and that moves the blood to the
The respiratory system consists of the nose, mouth, pharynx, larynx, trachea, bronchi and lungs. These provide a passageway to allow air in and out of the body. Every cell in the body requires oxygen to survive.
The circulatory system and the respiratory system work closely together to ensure that organ tissues and systems receive enough oxygen. Oxygen is required for cellular functions such as cell respiration. This is so the body’s organs and cells can work at fully; it is done by releasing chemical energy with in stored foods. The air breathed in and held in the lungs is transferred to the blood. The blood is circulated by the heart, which pumps the oxygenated blood from the lungs to the body organs and returns with deoxygenated blood.
The respiratory system is made up of organs and tissues that help you breathe. The main parts of this system are the lungs, the trachea, the diaphragm, alveoli and nasal cavity. The respiratory system starts with the mouth and the nose, where air is brought in, then passes through the larynx and the trachea into the chest cavity. http://www.nhlbi.nih.gov/health/ health-topics/topics/hlw/system The main organs of the respiratory system are lungs, which carry out this exchange of gases as we breathe. The
The respiratory system is in charge of getting the oxygen needed for respiration to the blood flow where it is passed by the blood cells around the body to reach each living cell.
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 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
“Obtaining oxygen and removing carbon dioxide are the primary functions of the respiratory system, which includes tubes that filter incoming air and transport air into and out of the lungs as well as microscopic air sacs where gases are exchanged” (Moini, 2013, p.497). Our respiratory system is broken down into two sections known as the upper respiratory tract and the lower respiratory tract.
The respiratory system provides a network of muscles and organs that helps a human breath. It brings in oxygen though inhaling and eliminates carbon dioxide through exhaling.
The lungs are the main organs in the respiratory system and they facilitate the exchange of oxygen and carbon dioxide when a person breaths.
According to the National Heart, Lung, and Blood Institute, Asthma is a chronic lung disease that affects the airways, which is comprised of tubes that carry air in and out of the lungs. People who experience difficulties breathing have inflamed airways. The inflammation causes the tubes to swell and become sensitive, especially when inhaling strong substances. As a result, the airways tighten and the muscles around the tubes become swollen and narrower. In addition, cells in the airways might produce more mucus. This sticky and thick mucus makes it even more difficult for air to pass into the lungs.
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 pathophysiology of Asthma includes inflammation of the airway. The way in which this works is from an irritant which can include dust, pollen, cedar, or cat hair. When a reaction occurs, the airways become inflamed and narrow. The narrowing occurs because once the inflammatory response is triggered by an irritant, histamines, immunoglobulin E antibodies, and leukotrienes are released. Because of this, mucous production occurs. Since the bronchioles are inflamed and narrow, breathing becomes difficult. Wheezing sounds can be heard due to the lack of air being able to easily move in and out of the narrowed bronchioles.
