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
the lung
-
internal respiration and cellulae respiration takes place
in the tissue throughout body
-
trachea also known as
windpipe
-
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
-
gas exchange occurs in what of the lungs?
Alveoli
-
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?
skeletal muscle
-
how many breath in a minute?
12
-
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
