The Respiratory system

Trachea

It is also known as windpipe, it filters the air we inhale and branches into the bronchi.

Lungs

The main organ of the respiratory system.

Pharynx

Tube that connects the mouth to the larynx and esophagus.

Bronchi

Tube that connects the trachea to the lungs.

Larynx

commonly called the voice box, and a connection between the pharynx and trachea

Alveoli

It is the tiny sac like structure present in the lungs which the gaseous exchange takes place.

Diaphragm

Breathing begins with a dome-shaped muscle located at the bottom of the lungs.

Epiglottis

It is a leaf-shaped flap of cartilage located behind the tongue, at the top of the larynx, or voice box.

Respiratory system

This system has a primary organ which is lungs, the function is to take in oxygen and expel carbon dioxide as we breathe.

Right Lung

It has 3 lobes: superior, middle, and inferior and it is the larger of the two lungs.

Left Lung

It has 2 lobes: superior and inferior and it is the smallest of the two lungs.

Inhale

To breathe in, diaphragm contracts, moves downwards

Exhale

To breathe out, diaphragm relaxes, moves upwards

Cilia

Hair like structures that filter out particles entering into your nasal cavity

Pleural Membrane/Pleura

Pleural membrane. A thin layer of tissue that lines the pleural cavity, the space that surrounds the lungs and lies underneath the chest wall.

Pneumonia

Disease caused by the inflammation of air sacs in the lungs

Bronchitis

Disease caused by inflammation of mucus membrane that lines the bronchial tubes

Emphysema

Disease caused when lung tissue is destroyed and air sacs are lost. The lungs become unable to deflate during exhaling

Asthma

A chronic lung disease that inflames and narrows the bronchial tubes

Tonsils

Glands in your pharynx that are a part of lymphatic system and help protect from pathogens

Pneumothorax

When your lung collapses due to air inside pleural cavity

Laryngitis

Inflammation of vocal chords, causing inability to speak

Tracheotomy

Procedure to provide oxygen to lower respiratory system when it cannot make it through the larynx

Bronchioles

Smaller branches of the bronchiole tree after the bronchi

Diaphragm, external intercostals, scalenes, sternocleidomastoid, pectorals minor

Muscles used in forceful inhalation

Diaphragm, internal intercostals, abdominal muscles

Muscles used in forceful exhalation

tidal volume

Amount of air that moves in and out of the lungs during a normal breath

vital capacity

the greatest volume of air that can be expelled from the lungs after taking the deepest possible breath.

inspiratory reserve volume

Amount of air that can be forcefully inhaled after a normal tidal volume inhalation

expiratory reserve volume

Amount of air that can be forcefully exhaled after a normal tidal volume exhalation

residual volume

Amount of air remaining in the lungs after a forced exhalation
