The Four Layers Of The Respiratory System

Unit 5 Outcome 2 – Energy Metabolism Booklet The Respiratory System 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 primary function of the respiratory

Respiratory system 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

Explain the basic process of the respiratory system from initial respiration through gas exchange. ➢ Inhaled air enters the nasal cavity, where it is cleaned, warmed and humidified on its way through the pharynx.

The Respiratory system is responsible for the breathing process. The breathing process entails inhaling and exhaling air in the body, absorption of oxygen from the air to produce energy, and getting rid of the byproduct of the process which is the carbon dioxide. The respiratory system is divided into two tracts; the upper respiratory tract and the lower respiratory tract. The following organs are a part of the upper respiratory tract: nose, mouth, pharynx and the larynx. While the lower respiratory tract consists of the trachea, lungs and the bronchial tree including all segments and the alveoli.

1/ What is the difference between the upper and lower respiratory? The respiratory tract is the system that allows you to breathe air into your lungs and back out again. The passageway that air travels through is divided into two sections, the upper respiratory tract, and the lower respiratory tract.

When I was a kid, I always curious about how the air comes out of my nose? What cause I feel uncomfortable if I cover my mouth and nose? Now, I know it is because of the respiratory system. The respiratory system is built up of the organs in our

Respiration and Circulation Name Description and function Nasal cavities The nasal cavity is an air filled space found behind the nose. Air is breathed in through the nose, which is divided by the septum to form the nostrils. The septum is mainly made of cartilage. Within the nose there are small hair like structures called cilia, which stop foreign particles from being inhaled by filtering them out of the air before it continues through the system. The nose contains mucous membranes which produce a substance called mucus, this is sticky and designed to collect dust, bacteria and other particles such as pollen and also to moisten the air. When air passes through the nasal cavity it is warmed to suit the body temperature. It is warmed by blood in the

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 human respiratory system is a variety of organs responsible for taking in oxygen and releasing carbon dioxide. The respiratory insists of key parts, which are the lungs, the airway, and the muscles of respiration. The functions of the respiratory system supplies oxygen to cells and removes carbon dioxide defending

The bronchioles, I believe to be the most complex part of the respiratory system. The bronchioles really do have an important role in the respiratory system. After the bronchi ends bronchioles begin. The bronchioles conduct air form the bronchi, pass air through the nose, mouth and then to the alveoli. The bronchioles function by distributing air through the lungs by constricting and dilating, this control the amount of air that goes through the lungs. The bronchioles began to taper off unto three tiny air passageways: the lobular bronchioles, terminal, and respiratory bronchioles. The bronchioles have no support by cartilage, and because of this they are more likely to be affected by conditions that may cause obstruction of the airway. The

Lower respiratory tract: -Trachea- Connects the larynx to the bronchi of the lungs in order to let air flow from the lungs to then respire.

Section 1 : Anatomy and Physiology 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).

Kennia Sanchez Respiratory System The human body needs oxygen all the time and that is why the respiratory system is there. The respiratory system is the one that provides the oxygen to all of the cells of the body and also removes the carbon dioxide. Carbon dioxide is a waste product that is very dangerous to people. The respiratory system has 3 parts which are:

What is the difference between the upper and lower respiratory tracts? According to the e-book and what I read "The upper respiratory tract includes the nose, nasal cavity, sinuses, pharynx, larynx, and the upper portion of the trachea. The lower respiratory tract consists of the lower portion of the trachea, the bronchial tree, and the lungs."

Blood is a thick, red, slightly These can be divided structurally into 2 parts, the upper respiration system which consists of nose and pharynx and the lower respiratory system which consists of larynx, trachea, bronchi and lungs.
