Vocabulary 

Pulmones- Lungs

Via aérea- Airway

Sangre venosa- Venous blood

Intercambio gaseoso- Gaseous exchange

Laringe- Larynx

Árbol bronquial- Bronchial tree

Tronco pulmonar- Pulmonary trunk

Glandula tiroides- Gland thyroid

The respiratory system is divided in two routes the superior and low and this compound:

Upper airway: Nostrils Pharynx

Low airway: Larynx Trachea Lungs Bronchi Bronchioles

His principal function is of allowing the oxygenation of the blood.

Functionally is divide in:Conductive portion:

He leads the air towards the lungs. (Nasal cavities, larynx, trachea and the principal right and left bronchi).

Respiratory Portion: It produces the gaseous exchange. Constituted by the bronchial tree. (Respiratory bronchioles, alveolar conduits, alveolar sacks and alveoli)

Vascularization of the lung according to his function

1.-Functional Vascularization formed by the pulmonary arteries right and left, originated from the pulmonary trunk.

2.-Nutritious Vascularization formed by the bronchial left arteries and the bronchial right artery that they originate directly the aorta.

Vocabulary Nasal cavity: Cavidad Nasal Skin: Piel Skull: Cráneo Environment: Ambiente Moisturize: Humedecer

Nasal Cavity

The nose and nasal cavity form the main external opening for the respiratory system and are the first section of the body’s airway the respiratory tract through which air moves. The nose is a

• structure of the face made of cartilage, bone, muscle, and skin that supports and protects the anterior portion of the nasal cavity.

Nasal Cavity The nasal cavity is a hollow space within the

nose and skull that is lined with hairs and mucus membrane. The function of the nasal cavity is to warm, moisturize, and filter air entering the body before it reaches the lungs.

Hairs and mucus lining the nasal cavity help to trap dust, mold, pollen and other environmental contaminants before they can reach the inner portions of the body.

Vocabulary Pharynx – Faringe

Larynx – Laringe

Nasopharynx – Nasofaringe

Oropharynx – Orofaringe

Laryngopharynx – Laringofaringe

Soft palate – paladar blando

Piriform fosase – fosa piriforme

Vocal cords- Cuerdas Vocales

Swallow- Deglutir

Breathe- Respirar

The pharynx is a muscular tube that connects the nasal cavities to the larynx.

The tube begins in the skull and ends inferior to the cricoid cartilage (C6).

The pharynx

The nasopharynxThe nasopharynx is found between the base of the skull and the soft palate, it is a continuation of the nasal cavity.

It performs a respiratory function by conditioning inspired air and propagating it to the larynx.

The Oropharynx

The oropharynx is the middle part of the pharynx, located between the soft palate and Lingual Tonsil.

The LaryngopharynxThe most distal part of the pharynx, this is located between the superior border of the epiglottis and inferior border of the cricoid cartilage (C6), at which point it becomes continuous with the esophagus.

Larynx

The larynx (voice box) is part of the respiratory system that holds the vocal cords.

It is responsible for producing voice, helping us swallow and breathe. Air passes in and out of the larynx each time the body inhales or exhales.

Air from the lungs passes over the vocal cords.

Trachea Arranges later of the larynx, below the cartilage cricoides, ending to level of T4.

Function: is to transport air towards the lungs. It possesses a cervical and a thoracic portion.

One finds compound from 15 to 20 tracheal cartilages, with form of horse-shoe, opened towards later, zone that is closed by the tracheal muscle, smooth, involuntary muscle, inerved by the sympathetic nervous system.

The trachea ends at a height of the esternal angle(T4), in the bifurcation of the principal bronchi rightly and left.

Bronchi The principal bronchi right and left enter to the hilium of lung.

Giving origin to ramifications: • The lobar (secondary)

bronchi. • The segmental (tertiary)

bronchi.

The bronchus source right is broader, more short and of disposition more vertical than the bronchus source left-handed. Principal bronchus gives origin to secondary bronchi right 3 and 2 left-handeds. Lobar bronchi give origin to ten segmental bronchi to the right side, and nine in the left-handed.

LungsAnatomy, function, definition and conditions

Anatomy The human lungs are a

pair of large, spongy organs optimized for gas exchange between our blood and the air. Our bodies require oxygen in order to survive. The lungs provide us with that vital oxygen while also removing carbon dioxide before it can reach hazardous levels.

Definition The lungs are a pair of breathing organs

located with the chest which remove carbon dioxide from and bring oxygen to the blood. There is a right and left lung.

FunctionHow do the lungs normally work?

The chest contains two lungs, one lung on the right side of the chest, the other on the left side of the chest. Each lung is made up of sections called lobes. The lung is soft and protected by the ribcage. The purposes of the lungs are to bring oxygen (abbreviated O2), into the body and to remove carbon dioxide (abbreviated CO2). Oxygen is a gas that provides us energy while carbon dioxide is a waste product or "exhaust" of the body.

Conditions Chronic obstructive pulmonary disease (COPD): Damage to the lungs

results in difficulty blowing air out, causing shortness of breath. Smoking is by far the most common cause of COPD.

Emphysema: A form of COPD usually caused by smoking. The fragile walls between the lungs' air sacs (alveoli) are damaged, trapping air in the lungs and making breathing difficult.

Chronic bronchitis: Repeated, frequent episodes of productive cough, usually caused by smoking. Breathing also becomes difficult in this form of COPD.

Pneumonia: Infection in one or both lungs. Bacteria, especially Streptococcus pneumoniae, are the most common cause.

Asthma: The lungs' airways (bronchi) become inflamed and can spasm, causing shortness of breath and wheezing. Allergies, viral infections, or air pollution often trigger asthma symptoms.

Acute bronchitis: An infection of the lungs' large airways (bronchi), usually caused by a virus. Cough is the main symptom of acute bronchitis.

Pulmonary fibrosis: A form of interstitial lung disease. The interstitium (walls between air sacs) become scarred, making the lungs stiff and causing shortness of breath.

Bronchioles They are placed in the end of the bronchi, the biggest ramification of the respiratory tract in the lungs, and end in the alveoli, small circular sacks where the oxygen is exchanged by carbon dioxide in the blood.

They are responsible of the distribution of the air and the resistance of the air flow in the lungs.

The bronchioles branch out, from the principal bronchi, in the smallest terminal and more numerous bronchioles, which in turn are divided in the respiratory bronchioles.

The Alveoli

The interior of the lungs is made up of spongy tissues containing many capillaries and around 30 million tiny sacs known as alveoli. The alveoli are cup-shaped structures found at the end of the terminal bronchioles and surrounded by capillaries.

The alveoli are lined with thin simple squamous epithelium that allows air entering the alveoli to exchange its gases with the blood passing through the capillaries.
