Respiratory System Raymond Padilla Period: 5
Major Functions of the Respiratory System
Obtains oxygen from the atmosphere and also removes carbon dioxide from body cells
Regulates temperature and water content of the air
Provides vocal sounds
Helps sense of smell
Upper respiratory structures and functions
The nose is supported by bone and cartilage and lets the nostrils provide openings for entrance and exit of air
The nasal cavity supports mucous membranes and also increases the surface area to warm, moisturize, and filter incoming air
Upper respiratory tract consist of the nose, nasal cavity, sinuses, and pharynx
Sinuses are air-filled spaces in the maxillary, frontal, ethmoid, and sphenoid bones that open into the nasal cavity
The pharynx is the space behind the oral and nasal cavities and larynx that supports producing sounds for speech
Lower respiratory structures and functions
The trachea is the what splits into the right and left primary bronchi and is the inner wall that lines with ciliated mucous membrane
The bronchial tree consist of 3 bronchi being the primary bronchi, secondary bronchi, tertiary bronchi.
The lower respiratory system consist of the trachea, the bronchi and bronchioles and last but not least the alveoli
The bronchioles are small tubular organs that branch off the segmental bronchi
The alveoli conducts rapid gas exchange between air and blood with associated capillaries
Layers of the pleura
The visceral pleura is the outer layer attached to the surface of each lung
The parietal pleura is the outer layer that lines the thoracic cavity
The pleura has 2 layers being the visceral pleura and the parietal pleura
Compare and contrast the mechanism of inspiration and expiration
And expiration(exhalation) is when air moves from low to high pressure
You can also have forced expiration and that allows for expiration to have more air than normal
Inspiration(inhalation) is when air moves from high to low pressure
Respiratory volumes and capacities
There are 4 distinct respiratory volumes, in order they are the tidal volume, inspiratory reserve volume, expiratory reserve volume, residual volume
And there are 4 respiratory capacities which are inspiratory capacity, functional residual capacity, vital capacity, and total lung capacity
Respiratory capacities happen when there are combinations of 2 or more respiratory volumes
Internal vs. external respiration
When it comes to internal vs external respiration external is is O2 and CO2 getting exchanged between the the lungs and blood while on the other hand internal is is O2 and CO2 exchange between systemic blood vessels and also tissues
Volume and Pressure relationships in thoracic cavity
The volume of the given amount of gas is inversely proportional to it's pressure when temperature is held constant
When the thoracic cavity expands it increases volume which leads to a decrease in intra-alveolar pressure, creating a pressure lower than atmospheric pressure
Disorders of the respiratory system
Tuberculosis is a bacterial infection in the respiratory system that is caused by drug abuse or alcohol abuse the symptoms consist of chest pain, fatigue, fever, surgery is a treatment option or taking medication
There are a bit of disorders when it comes to the respiratory system so the last disorder I'll choose is lung cancer which is when uncontrolled cell growth & development of tumors happen in the lungs it's mainly caused by smoking or air pollution but one that stands out and is a cause of getting lung cancer is radon gas as for symptoms you receive chest pain, fatigue, and also weight loss and much more. When it comes to treatment option though there is chemotherapy or radiation
COPD stands for chronic obstructive pulmonary disorder it can be caused by a variety of things like tobacco smoke and when it comes to symptoms usually the person has tightening in the chest or wheezing there are treatments being medication or antibiotics
