It usually goes unnoticed by the average human, but you take a breath twelve to sixteen times per minute, every single day. This is made possible by the respiratory system. The respiratory system is the group of organs in the body that enable a person to breathe; this system, like the other systems, is vital for survival. The respiratory system’s main function is gas exchange, which in turn maintains normal blood pH, maintains body temperature, and keeps cells alive to sustain the body. The respiratory system provides a person’s sense of smell, and a person’s voice and sounds they can make are possible due to this system. Respiration begins and ends at the nose or mouth where oxygen is inhaled and carbon dioxide is exhaled. The respiratory system has many different parts that all work together to help maintain homeostasis of the body. It is easier to understand how the respiratory system works when one knows all of these different organs and their individual duties. The anatomy of the respiratory system makes up the respiratory tract and can be divided into three major parts: the airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles; the lungs; and the muscles of respiration (Taylor). The respiratory tract can be divided into two sections which are the upper tract and the lower tract.
The upper tract starts at the nose and naval cavity or mouth and ends at the pharynx; the lower tract begins at the larynx and ends at the alveoli. The first section of the airway is the main opening of the respiratory system: the nose and naval cavity. The nose is on the outside of the body and is made of cartilage, bone, muscle and skin. It covers the front of the nasal cavity which is a space with...

...hemoreceptors notice changes in the chemical composition of blood and stimulate ventilation. Mechanoreceptors respond to pressure or distortion in physical setting which also stimulate ventilation that will fix the present problem.
The respiratory system is an amazing body system. When the respiratory system is mentioned, it is common for people to only think about breathing, but there is so much more to it. The respiratory system works with other systems to allow the body to stay alive and well; all of the components of the system work together to make life possible. The many different processes of the respiratory system maintain overall homeostasis of the body. The average person who lives to be eighty years will take about 672,768,000 breaths in their entire lifetime. Over time, the respiratory system wears down, but it doesn’t stop working to keep you alive

Anatomy And The Respiratory System Essay

- The Respiratory System Anatomy has to do with the structure of the body, or how it is made. Physiology has to do with how it all works together. Just like a car, unless you know all of the parts, how they work individually, and also how they work together, you won 't know how to figure out what the source of the problem is, or how to fix it. One of the few systems in the body is the respiratory system. Each system has an important job in keeping the body functioning....   [tags: Respiratory system, Oxygen, Vertebrate trachea]

Essay about Smoking And The Respiratory System

- Smoking and the Respiratory System Respiratory system is an important part of our body. It is responsible for gaseous exchange, external and internal respirations, which are some of the most important functions in our body. While it is important, the system is also really delicate. If it is exposed to many pollutants, it can lead to serious diseases or even death. Smoking is a perfect example of exposing to pollutants. Most people smoke because they think they look stylish and become addicted to it, which cause bigger health problems to their respiratory system as well as other body parts....   [tags: Respiratory system, Oxygen, Carbon dioxide, Blood]

Respiratory Diseases: Emphysema Essay

- The simple act of breathing is often taken for granted. As an automated function sustaining life, most of us do not have to think about the act of breathing. However, for many others, respiratory diseases make this simple act thought consuming. Emphysema is one such disease taking away the ease, but instead inflicting labored breathing and a hope for a cure. 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....   [tags: respiratory system, smoking]

The Body 's Respiratory System Essay examples

- Introduction The body’s respiratory system’s functionality is primarily simple. Starting with inhalation first, oxygen rich air enters either the nostrils where cilia filter out foreign particles such as dust. After these foreign particles are coughed or sneezed out of the airway, air then passes through the nasal cavity into the oropharynx. From here the air containing oxygen the body needs passes through the laryngopharynx to the larynx, which is the transitional point between the upper and lower airways, and is protected by the epiglottis....   [tags: Respiratory system, Oxygen, Carbon dioxide]

The Respiratory System Essay

- ... The first supporting part are the ribs. This protects the lungs as well as the heart from damage. Without the ribs, if we got hit in the chest, our lungs would collapse instantly. The other supporting is the large sheet of muscle below the lungs called the diaphragm. It becomes thinner every time we breathe which creates more more space for the lungs to inflate. Your breathing is regulated by the respiratory system control center at the base of our brain. This part sends messages down the spine to make sure our breathing muscles are contracting a relaxing regularly which makes breathing automatically unnoticeable until we actually think about it....   [tags: inhaling, exhaling, oxygen, carbon dioxide]

Anatomy: The Respiratory System Essay

- The purpose of the respiratory system is breathing which is also known as ventilation. The process of cyclically moving air in and out of the lungs so alveolar air that has given up oxygen and picked up carbon dioxide can be exchanged for fresh air from the atmosphere. Ventilation is accomplished from the system alternately shifting the direction of the pressure gradient for airflow between the atmosphere and the alveoli through the expansion and recoiling of the lungs. Contraction of the inspiratory muscles indirectly produces inflation and deflation of the lungs by continuously expanding and compressing the thoracic cavity with the lungs following its movements....   [tags: alveolar air, oxygen, homeostasis]
