What are the three parts of the respiratory system?
The three major parts of the respiratory system all work together to carry out their task. The airways (nose, mouth, pharynx, larynx etc.) allow air to enter the body and into the lungs. The lungs work to pass oxygen into the body, whilst removing carbon dioxide from the body. The muscles of respiration, such as the diaphragm, ...
How many alveoli are there in the human body?
There are estimated to be three million alveoli in the average lung. Diaphragm. The diaphragm is an important muscle of respiration which is situated beneath the lungs.
What are the respiratory problems?
You should also know that many conditions and illnesses can affect the respiratory system, some of the common problems include: - 1 Asthma – Asthma leads to a narrowing of the airways, which can cause breathlessness and wheezing. 2 Bronchitis – A condition that causes inflammation of the mucus lining within the one lung or both. 3 Emphysema – A disease that affects alveoli. 4 Influenza – An illness caused by a virus that can have a detrimental affect on one’s respiratory system. 5 Laryngitis – When one’s vocal chords (larynx) become inflamed. 6 Pneumonia – When one or both lungs become inflamed. 7 Lung cancer – Although commonly associated with smokers, lung cancer can also affect those who do not smoke.

What is the primary opening for the respiratory system?
The muscles of respiration, such as the diaphragm, work in unison to pump air into and out of the lungs whilst breathing. The nose is the primary opening for the respiratory system, made of bone, muscle, and cartilage. The nasal cavity is a cavity within your nose filled with mucus membranes and hairs.
What is the mouth?
Mouth. Also called the oral cavity, the mouth is the secondary exterior opening for the respiratory system. Most commonly, the majority of respiration is achieved via the nose and nasal cavity, but the mouth can be used if needed. Inhaling air through the mouth allows more inhalation, as the oral cavity is far larger than the nasal cavity.
Why is it important to inhale air through the mouth?
Inhaling air through the mouth allows more inhalation, as the oral cavity is far larger than the nasal cavity. The air also has less distance to travel, meaning more air can enter your body and be used faster. The oral cavity has no hairs or filtering techniques, meaning the air you inhale does not undergo the filtration process.
What are the bones and muscles that surround the respiratory system?
Some of the bones and muscles in the respiratory system include your: Diaphragm: Muscle that helps your lungs pull in air and push it out. Ribs: Bones that surround and protect your lungs and heart. When you breathe out, your blood carries carbon dioxide and other waste out of the body.

Which organs are responsible for oxygenation?
Lungs: Together the lungs form one of the body’s largest organs. They’re responsible for providing oxygen to capillaries and exhaling carbon dioxide.
How many terminal bronchioles are there in the lung?
There are more than 1000 terminal bronchioles in each lung. The muscular walls of the bronchioles do not contain cartilage like those of the bronchi. This muscular wall can change the size of the tubing to increase or decrease airflow through the tube.
How many regions are there in the pharynx?
The pharynx is divided into three major regions: the nasopharynx, the oropharynx, and the laryngopharynx. Figure 5. The pharynx is divided into three regions: the nasopharynx, the oropharynx, and the laryngopharynx. The nasopharynx is flanked by the conchae of the nasal cavity, and it serves only as an airway.
Why do colds cause ear infections?
In addition, auditory (Eustachian) tubes that connect to each middle ear cavity open into the nasopharynx. This connection is why colds often lead to ear infections. The oropharynx is a passageway for both air and food. The oropharynx is bordered superiorly by the nasopharynx and anteriorly by the oral cavity.
What is the purpose of the conducting zone?
The major functions of the conducting zone are to provide a route for incoming and outgoing air, remove debris and pathogens from the incoming air, and warm and humidify the incoming air. Several structures within the conducting zone perform other functions as well.

How do you know if you have asthma?
Symptoms of an asthma attack involve coughing, shortness of breath, wheezing, and tightness of the chest. Symptoms of a severe asthma attack that requires immediate medical attention would include difficulty breathing that results in blue (cyanotic) lips or face, confusion, drowsiness, a rapid pulse, sweating, and severe anxiety. The severity of the condition, frequency of attacks, and identified triggers influence the type of medication that an individual may require. Longer-term treatments are used for those with more severe asthma. Short-term, fast-acting drugs that are used to treat an asthma attack are typically administered via an inhaler. For young children or individuals who have difficulty using an inhaler, asthma medications can be administered via a nebulizer.
What are the major respiratory structures?
Figure 1. The major respiratory structures span the nasal cavity to the diaphragm. Functionally, the respiratory system can be divided into a conducting zone and a respiratory zone. The conducting zone of the respiratory system includes the organs and structures not directly involved in gas exchange. The gas exchange occurs in the respiratory zone.
How does the respiratory system work with the circulatory system?
The respiratory system interacts with the circulatory system to transfer oxygen from fresh air to red blood cells in the lung arteries while also releasing carbon dioxide from the blood into the air in the lungs. When a person exhales, this used air leaves the body. The heart pumps the blood with the oxygenated red blood cells from ...
What are the respiratory and circulatory systems?
The Respiratory & Circulatory System in the Human Body | Sciencing. The circula tory and respiratory system interactions form the basis for supporting life in higher animals. The heart, arteries, veins, lungs and alveoli have to work together to supply the body with oxygen and get rid of carbon dioxide, the human respiratory system's form of waste.
What are the organs of the respiratory system?
