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).
To explain normal functioning of the respiratory system, it is best to know that the respiratory system in human beings is comprised of the upper respiratory tract that consists of the nasal passages, pharynx and the larynx. The lower respiratory tract is composed of the trachea, the primary bronchi and the lungs. The primary function of the respiratory system is to supply oxygen to the blood in the body. Oxygen is delivered to all parts of the body. The respiratory system does this while breathing is taking place. During the process of breathing, one inhales oxygen and exhales carbon dioxide. This exchange of gases within the thoracic cavity takes place at the alveoli within the body (Grant, 2004). The average adult's lungs contain about 600 million of these air-filled sacs that are surrounded by capillaries (Grant, 2004). The inhaled oxygen passes into and through the alveoli and is diffused through the capillaries into the arterial blood. Meanwhile, the waste-rich blood from the veins releases the carbon dioxide into the alveoli. The carb...

...over 1.8 million Americans with the disease, which ranks fifteenth among chronic conditions that cause limitations of activity. Smoking usually causes the disease, but a small number of cases are caused by an inherited defect (Swartout, 2002).
In conclusion, this is how the respiratory system functions normally day-by-day as well as how it keeps homeostasis with its contributing factors. Also, there are several ways in which the respiratory system can enhance or promote health and wellness as described in such ways as activities of daily living and other areas of occupation. The respiratory system can affect performance skills have also been described in the above passages through examples that apply to our everyday lives. And finally research was provided on how the respiratory system can negatively affect us throughout our lifespan from conception to death.
The respiratory system is the system for taking in oxygen and giving off carbon dioxide in organisms. The respiratory systems of California sea lions, king cobras, and bald eagles have a few similarities and differences, but they all allow the intake of oxygen for each organism.
When you breathe in, air containing carbon dioxide (CO2) and oxygen (O2) it moves down your trachea; a tunnel containing cartilage and smooth tissue. Air then travels through two hollow tubes called bronchi; narrow branches lined with smooth muscle, mucosal and ringed cartilage to support the structure. The bronchi divide out into smaller tunnels called bronchioles; are small branches 0.5-1mm, lined with muscular walls to help dilate and constrict the airway. At the end of the bronchioles are little air sacs called alveoli; which assist in gas exchange of O2 and CO2. (Eldridge, 2016) Towards the end of alveoli are small blood vessel capillaries. O2 is moved through the blood stream through theses small blood vessels (capillaries) at the end of the alveoli and the CO2 is then exhaled. (RolandMedically,
The respiratory system undeniably serves a very important function in the body. Anyone who has had any event where they couldn’t breathe normally, or maybe not at all, recognizes the importance and mental peace that comes with being able to breathe stress free.
The respiratory system has the function of getting rid of carbon dioxide and acquiring oxygen. It works closely with the circulatory system to feed the body the proper amounts of oxygen it needs to function efficiently. The respiratory system of an American Mink is very similar to that of a human in spite of the fact that there are some minor modifications. Both Humans and Minks have two lungs, the right lung is larger and has three lobes and the left lung has two lobes. The reason why the left lun...
I only chose respiratory as an answer. However, the correct answers are respiratory and cardiovascular because of the pulmonary circulatory system. Gas exchange occurs at pulmonary capillary beds.
The circulatory system and respiratory system share a highly important relationship that is crucial to maintaining the life of an organism. In order for bodily processes to be performed, energy to be created, and homeostasis to be maintained, the exchange of oxygen from the external environment to the intracellular environment is performed by the relationship of these two systems. Starting at the heart, deoxygenated/carbon-dioxide (CO2)-rich blood is moved in through the superior and inferior vena cava into the right atrium, then into the right ventricle when the heart is relaxed. As the heart contracts, the deoxygenated blood is pumped through the pulmonary arteries to capillaries in the lungs. As the organism breathes and intakes oxygenated air, oxygen is exchanged with CO2 in the blood at the capillaries. As the organism breathes out, it expels the CO2 into the external environment. For the blood in the capillaries, it is then moved into pulmonary veins and make
The body is changing and adjusting to the internal and external environment so they must be adjusted to stay on point. One example of preventing respiratory distress is limiting exposure to allergens that may trigger the body’s external environment. Our perception of homeostasis could be thought of as an artificial balance.
Healthy lung tissue is predominately soft, elastic connective tissue, designed to slide easily over the thorax with each breath. The lungs are covered with visceral pleura which glide fluidly over the parietal pleura of the thoracic cavity thanks to the serous secretion of pleural fluid (Marieb, 2006, p. 430). During inhalation, the lungs expand with air, similar to filling a balloon. The pliable latex of the balloon allows it to expand, just as the pliability of lungs and their components allows for expansion. During exhalation, the volume of air decrease causing a deflation, similar to letting air out of the balloon. However, unlike a balloon, the paired lungs are not filled with empty spaces; the bronchi enter the lungs and subdivide progressively smaller into bronchioles, a network of conducting passageways leading to the alveoli (Marieb, 2006, p. 433). Alveoli are small air sacs in the respiratory zone. The respiratory zone also consists of bronchioles and alveolar ducts, and is responsible for the exchange of oxygen and carbon dioxide (Marieb, 2006, p. 433).
Whilst looking at the impact that breathlessness can have on patient the author will look at the physical, psychological and social health implications and how this can affect the overall (holistic) quality of life for these patients. Often these three areas overlap and the physical implications of breathlessness can have a direct effect on the patient’s social health, financial ability to provide for themselves and others, which in turn affects the person physiological well-being or vice versa.
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
The human lungs are a pair of large, sponge like organs that are optimised for gas exchange between the blood and oxygen. The human body requires oxygen in order to survive and function. The lungs are responsible for providing vital oxygen while also removing the carbon dioxide before hazardous levels are reached within the body.
The respiratory system has six major areas that works together that allows the body to breathe, prevent choking, and not to allow harmful debris to enter the respiratory system are some of the functions that the respiratory system does. The respiratory system is divided into two regions, the upper and lower respiratory. The upper respiratory consists of the Nose (nasal) and Pharynx while the lower respiratory embodies the rest of the system which includes the Larynx, Trachea, Bronchioles and Lungs. The information provided will be done by three individuals the upper respiratory tract will be provided by Mr. David Brown, the lower respiratory tract will be given by Ms. Brianna Agee and the infectious diseases will be provided by Mr. Derrek Woods.
The Respiratory System 1. Define respiration. Respiration is the process of converting glucose to energy, which goes to every cell in the body. 2. Describe the organs of external respiration.
There are three parts that make up the respiratory system; muscle, lungs and the airway (respiratory system 2017). Although, there are three main parts the main organ is the lungs. The respiratory system delivers air to the alveoli, while giving and removing Carbon dioxide. Asthma is one of the many respiratory diseases. From personal experience, Asthma can affect one’s life in many ways. Asthma is when your airway is inflamed and produces a lot of mucus which makes it hard for one to breathe. Many are affected by respiratory diseases, because it effects their everyday
The roles of the circulatory and respiratory system both carry important responsibilities and are essential in their jobs to the human body. The circulatory system is one, if not the, most important system in the human body. The circulatory system is made up of the heart, blood, and blood vessels. Within the blood vessels, there are three types: arteries, veins, and capillaries. The heart is an organ made up of cardiac muscle that has a role similar to a pump. When the muscles in the heart contract, it pumps fresh blood away from the heart, through a main artery called the aorta, and to the organs and cells of the body. Nutrients and oxygen then enter the cells through diffusion of the tissues. The respiratory system transports oxygen to the circulatory system. When transporting oxygen to the circulatory system, this will in turn transport oxygen to the rest of the cells in the body. Aside from transporting oxygen to the body, the respiratory system also plays a role in the removal of carbon dioxide and other contaminants in the body. These two systems effectively and efficiently work together in order to supply the body with oxygen and remove carbon dioxide and any other
