RESPIRATORY SYSTEM Flashcards
What is BRONCHITIS?
A chest infestation usually requiring antibiotics to kill the bacteria
What makes the ALVEOLI so good at their job?
The ALVEOLI have a SINGLE CELL WALL and a rich supply of blood just the other side of it. They are shaped like BUNCHES OF GRAPES to increase SURFACE AREA.
This is where the RESPIRATION takes place, the gas exchange so this is respiration. Oxygen into the blood and carbon dioxide put.
What makes DIAPHRAGM so good at its job?
The DIAPHRAGM is shaped like a PARACHUTE. When the DIAPHRAGM is relaxed the RIB CAGE goes in and the LUNGS DEFLATE forcing air up the TRACHEA and out the MOUTH
ASTHMA
Asthma is a common long-term inflammatory disease of the airways of the lungs. It is characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm. Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath.
Compare the PEAK FLOW to a SPIROMETER as a DIAGNOSTIC TECHNIQUE
A PEAK FLOW is a small device that you blow into. It measures the FASTEST RATE OF AIR that you can blow out of your lungs. A SPIROMETER look at how well your lungs work. It shows how well you breathe in and out.
CHRONIC OBSTRUCTIVE PULMONARY DISEASE
COPD is a common condition that mainly affects middle-aged or older adults who smoke. Many people don’t realise they have it.
The breathing problems tend to get gradually worse over time and can limit your normal activities, although treatment can help keep the condition under control.
PNEUMONIA
Pneumonia is an inflammatory condition of the lung affecting primarily the small air sacs known as alveoli. Typically symptoms include some combination of productive or dry cough, chest pain, fever, and trouble breathing
Explain how X RAYS work?
The beam travels through the air and. Ones into contact with our body tissues and produced an imagine on a metal film. Soft tissue such as skin and organs cannot absorb the high energy rays and the beam passes through thrmZ dense material inside our bodies like bonds absorb the radiation. Infections show up as an identifiable area
