Respiratory System

Nasal Cavity, Pharynx, Larynx, Trachea, Bronchi, Bronchioles, Alveoli

Nasal cavity- The nasal cavity has three key components: vestibule, main nasal cavity and the paranasal sinuses. Here we see the vestibule, the area within the nostril. The epithelium here represents a continuation of the keratinized, stratified squamous epithelium of the outside skin. Within the vestibule are vibrissae (hairs) that serve to filter out the larger particles entering in the inhaled air

Pharynx- essentially same cell type, dont forget the mucous secretions- essentially same fxn

Larynx- The larynx is situated between the pharynx and the trachea.

T

he pharynx is situated between the nasal cavity and the larynx. The portion exclusively used for breathing (nasopharynx) is lined by the usual pseudostratified ciliated epithelium (respiratory epithelium) found throughout most of the conducting portion of the respiratory system. The remaining components of the pharynx (oropharynx, hypopharynx) are lined by a protective stratified squamous epithelium, appropriate to their role in abrasive activities such as swallowing and coughing.

The trachea extends from the larynx to the primary bronchi of the lung. It consists of a series of C-shaped hyaline cartilage rings that keep the airway open (the esophagus, which lacks such rings, is collapsed except when swallowing). The posterior, open ends of the cartilage rings are connected by trachealis muscle. This muscle contracts to narrow the trachea during coughing, providing a faster air flow. Elastic fibers in the mucosa and submucosa provide flexibility to the trachea

After the trachea, inspired air passes to the bronchi, distributing bronchioles, respiratory bronchioles, alveolar ducts, alveolar sacs and alveoli. Gas exchange occurs in alveoli, which first appear on the respiratory bronchioles.

Please check out a physiology or histology book for more info

elevation
not sure there is a term, but by expanding your rib cage, you create negative pressure in your chest cavity, which pulls in air via your mouth and nose to fill the void.

I think it would be elevation, but I agree - there is no specific term that i learned in school for that specifically.

respiration and digestive systems are connected in many ways. respitory gives off oxygen which. gives in carbon dioxide which travels through the body and down to the lungs ( by the stomach)(above)

Smoking can really harm your lungs and make them black if you smoke too much. This is due to the build up of tar in the lungs which will eventually lead to lung cancer.

--

If someone smokes more than once and is constantly smoking then they could end up getting lung cancer. Cigarettes get addicting, so they are hard to stay away from for a smoker. And yes in time your lungs will get black. Also it is common for smokers to get a big hole in their neck, so they have to use a remote like piece of equipment to help them talk. And then some people have to walk around with little breathing tubes.This might not seem like the most educated answer but let me tell you this it is way more accurate then the ones above, and then the ones you find.
smoking can make your lungs bad and damage your teeth smoking has a type of acid in it and it's not good for your lungs.

Our lungs are precious, and the most important part of our respiratory system. These organs are responsible for absorbing and distributing all the oxygen that our body needs in order to function normally.

Fitness: It is important to keep your lungs fit. Regular physical activity is the only consistent way to ensure the fitness of your respiratory system. The more you use your lungs and diaphragm, the more fit they will - just like any other muscle in your body.

Protection: The more careful we are about what we breath into our lungs, the less chance there is that they will be damaged. There are some inadvertent or accidental situations that we can be careful to avoid - staying inside on very smoky or smoggy days, wearing masks when using harmful chemicals, etc. But there are also some very deliberate things people do that harm their lungs - smoking is the worst. And the easiest way to avoid smoking, is never to start.

Most respiratory diseases are air-borne. It is important to breathe clean, fresh air. Cover your mouth and nose when you are in a crowed place or when the air is heavily polluted. Wearing a mask over the nose is now common in urban areas and in factories.

Respiratory ailments are contagious. Colds and coughs are visible signs of most respiratory ailments. Do not stay too close to people who have them. When they cough or sneeze, germs are sure to be in the air. You may catch these germs and get sick, too. In addition, get immunized against flu yearly, get pneumonia vaccine as recommended (based on your age and health history), and make sure you have received the TDaP vaccine at least once to offer protection against pertussis (whooping cough).

Breathing from your abdomen can help as it relaxes your accessory breathing muscles and gets you breathing more naturally as were designed to do. Lie on your back with one hand resting gently on your abdomen and one on resting on your chest, and see which one rises as you breathe. You should aim to keep your chest hand still and abdomen hand rising and falling with your breathing.

If you are an asthmatic, make sure you have the knowledge and skills to keep your condition well-controlled. If you are frequently using your rescue inhaler, it's a sign that you need to add controller medications.
