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
