What are the two main main Component of respiratory system?
Upper and lower respiratory tract
what does the upper respiratory tract do?
It filter and warms air
what does lower respiratory tract do?
does some transporting of air and gas exchanges
what are the different respiration process?
extenal, internal and cellular respiration
External respiration is?
when gas exchange is made between air and blood
Internal respiration is?
is gas exchange between blood and tissue
Cellular respiration is?
oxygen use to produce ATP, Carbon dioxide as waste
Lower respiratory tract consist of:
Larynx, trachea, right and left bronchus, aleai, bronchioles
what is the function of the larynx?
maintain open airway, routes food and air appropriately, asisit in sound
Function of the Trachea?
transport air to and from lungs
function of bronchi?
branch into lungs
function of bronchioles?
branch farter into lungs
fuction of lungs?
transport air from circulatory system to Alveoli for gas exchange
what is inspiration?
movement of air into lungs
what is expiration?
movement of air out of lungs
what are the step to inspiration? Air flow in
signal, contract, volum increase, pressure drops, and air rush in
what is step to Expiration? Air flowing out
stop nerves signal, muscles relaxes, volume decrease, pressure goes up, air rush out
where do gas exchange takes place?
in the lung
breathing is done by the respiratory system and with the help of what other organ or system?
bone, muscle and nerves
External respiration take place in
internal respiration and cellulae respiration takes place
in the tissue throughout body
trachea also known as
trachea consist of a series of
c-shaped, imcomplete rings
the trachea branches into two airways called
left and right bronchi
lung are organs of
gas exchange occurs in what of the lungs?
During inspiration what happen?
the rib moves upwards and outwards enlarging the thoracic cavity
what happen durin expiration?
the muscle relax and the ribs return to their relaxed position
the lungs are organ containing what?
systems of bronchi, bronchioles, blood vessels, and 300 million alveoli.
Gas exchange occurs between what two part of the lung?
Alveoli and capillaries
bone and muscle of respiration includes
ribs, intercostal muscles between the ribs, and diaphragm.
what is a diaphragm?
a sheet of muscle that seperate the thoracic cavity from abdominal cavity
intercostal and diaphragm is part of what kind of muscle?
how many breath in a minute?
what is the tidal volume of a single breath of air?
500 milliliter (pint)
what is vital capacity?
the miximal volume exhale after maximal inhalation
