Respiratory System By: Gabe G. Jack P. Jackson T. & Claire T.

Table #7

Overall function

Cells of the human body require a constant stream of oxygen to stay alive and function properly

The respiratory system provides said oxygen to the blood cells

Removes carbon dioxideThe major organ of the respiratory system are

the lungs

Nose & Mouth

We inhale air through and out of the nose and mouth hundreds of times every day

The nose is the primary opening for the respiratory system

The mouth is the secondary external opening for the respiratory tract

Pharynx & Esophagus

As air continues down your throat it goes past the pharynx or throat

Muscular funnelEsophagus and larynx connectedThe esophagus is a long tube that connects from

the throat to the stomach

Larynx

The Larynx (also known as the voice box) is a short section of the air way that is connected to the trachea

The Larynx contains special structures called vocal folds that allow the body to produce vocal sound

Trachea

The Trachea (better known as the windpipe) is a 5-inch long tube that connects the Larynx to the bronchi

Allows air to pass through the neck and into the thorax

The open cartilage in the trachea allows the esophagus to expand into the space

The main function of the trachea is to provide a clear airway for air to enter and exit the lungs

Bronchi and Bronchioles

The airway splits into left and right branches at the end of the trachea known as the primary bronchi

The bronchi carry air into the lobes of the lungsThe secondary bronchi split into smaller tertiary

bronchi within each lobe The tertiary bronchi split into many smaller

bronchiolesEach bronchiole further splits into many smaller

branches called terminal bronchioles

Lungs

The lungs are a pair of large, “spongy-like” organs found in the thorax lateral to the heart and superior to the diaphragm

The interior of the lungs is made up of spongy tissues containing many capillaries

There are around 30 million tiny sacs in the tissue which are known as alveoli

The main function of the lungs is to exchange gases we breathe

Muscles of Respiration

Surrounding the lungs are sets of muscles The surrounding muscles support inhalation and

exhalation An important muscle of respiration in the

human body is the diaphragmThe main responsibility for intercostal muscles is

to evaluate the ribs

Asthma

Asthma is a common chronic inflammatory disease in the airways of the respiratory system

Symptoms include wheezing, coughing, chest tightness, and shortness of breath

There is an estimated 240-330 million people worldwide who are affected by asthma

An average of 350,000 annual deaths from the disease

Bronchitis

Bronchitis (also known as a chest cold) is an inflammation of the bronchi lungs

The different types of bronchitis are acute and chronic bronchitis

Symptoms include coughing up mucus, wheezing, shortness of breath, and chest discomfort

Millions of people around the world are affected by chronic bronchitis alone

An estimated annual death rate per year worldwide is about 10,000 people

Treatment

As bronchitis and asthma are rising health problems in today’s developing community, people have pursued a goal to end such diseases

Unique and effective technological and professional tactics are used by doctors during these certain kinds of checkups

Treatments for such diseases are used to as well indicate the condition of your breathing problems

These treatments in result give doctors a heads up on what the best possible case scenario there is out there to resolve and fight off diseases

Peak expiratory flow test

Spirometry test

Chest x-ray test
