Pulmonology

Specialty that studies respiratory disease

Pulmonologist

person who studies or practices respiratory disease

Pulmon/o

lung

Logy

the study of

Lungs

fill most of the thoracic cavity

the trachea

is divided into the bronchi that enter right and left lungs in thoracic cavity

Respiratory system

Begins in the nose, mouth and continues in the pharynx and trachea

Respiratory system

Consist of the right and left lungs, the airway passageways that connect lungs to outside of body

Upper Respiratory system

Located in head and neck, thoracic cavity
• Includes nose,
o naval cavity,
o and pharynx (throat)

Upper Respiratory system

Shares stutters with ENT (ear, nose and throat) systems

Lower Respiratory System

Located in neck and thoracic cavity

Lower Respiratory System

• Includes larynx (voice box)
o Trachea (wind pipe)
o Bronchi
o Lungs
o Diaphragm

Lower Respiratory System

Brings oxygen into the body and express carbon dioxide from the body

Nose

contain the nasal cavity which is divided internally by nasal septum into right and left side

Superior, middle inferior tubinates

Each side of the nasal septum has 3 elongated with bony projections know as the

Superior, middle inferior tubinates

act as barriers to divide and slow down inhaled air so that it can pick up warm the and moisture.

Cilia,

small hairs in the nasal cavity and lungs that move mucus and dirt, etc out of the lungs and nasal cavity

Pharynx

throat

larynx

voice box

Trachea

wind pipe

Pharynx

Acts a common passage for inhaled air and ingested food.

Larynx

Passage way for inhaled and exhaled air

Larynx

Remain open during respiration and speech allowing air to pass through the voice cord.

epiglottis

During swallowing the muscle in the neck pull the _____ and seal off the larynx so that food moves around and over the top of the esophagus not into the larynx.

trachea

A column of C shaped rings of cartilage that provide support the

Bronchi

fat part of the branches

right and left main stem bronchi

Where the trachea ends as it divides into an inverted Y forming .

bronchioles

Each bronchi enters a lung and then further divides into smaller passageways know as

Bronchioles

smooth muscles instead of cartilage

Lumen

is the central open of bronchi and broncolies through which air passes

Right lung

has 3 lobes

Left lung

has 2 lobes

apex

The rounded top of each lung is

diaphragm

The bottom or base of each lung lies along the

Plura

Each lung is surrounded by a double layer serums membrane know as

visceral

Membrane that covers the surface of the lung is known as

Parietal Pleura

The membrane that covers the wall of the thoracic cavity is known as

pleura fluid

a slippery, watery fluid that allows the 2 membranes to slide smooth past one another as the lungs expand and contract during respiration.

Alveoli

A hallow sphere of cells that expands and contracts with each breath

Thoracic Cavity

• Consist of
o Sternum
o Ribs
o Spinal column
o Surrounds and protects the cavity

The mediastinum

irregular shaped area between the lungs and contains the trachea

Diaphragm

is a muscular sheet that contacts to enlarge the thoracic cavity and draws in air

Accessory muscles

of the respiration system are sometimes needed to help expand the thoracic cavity

inhalation or inspiration

Breathing in is known as

exhalation or expiration

Breathing out is known as

Eupnea

Normal depth and rate of respiration is known as

Carbon dioxide

a gaseous waste product of metabolism move from the blood into the alveoli

Mouth and
Nasal cavity to the
Pharynx to the
Larynx then to
Trachea then the
Bronchi then into the
Bronchioles into the
Alveoi where
Gas exchange of co2 and o2 takes place

Flow of Air

Cyranosis

condition of blue: body can't filter the co2 so it is suffication from insided

Dyspnea

shortness of breath

COPD

chronic obstruction pulmonary disorder

Asthma

narrowing of the hypersensitive reaction that the bronchioles constrict

Atelectasis

is the collapse of part or all of a lung

Bronchitis

is an inflammation of the main air passages (bronchi) to your lungs

Pneumonia

is an inflammation of the lung, usually caused by an infection.

Pneumonia

• Caused by :
o bacteria,
o viruses
o and fungi.
o Exposure to chemicals

cockroaches

Exposure to________ can has been found to cause asthma in a fetus and poor immune system in inner city children
