respiratory system pt 2

outer layer of serous membrane

inner layer of serous membrane

between the two layers of series membrane and this contains a lubricating fluid that prevent friction as the lung expands

when brain receptors perceive too much carbon dioxide in the blood, they signal the body to

transport oxygen in the cell and exchange of gases (O² and CO²)

respiration is controlled by the

contains the respiratory center which can be stimulated by chemoreceptors

special cells that detect changes in partial pressure of oxygen and carbon dioxide

refers to movement of air in and out of the lungs or breathing, when the air enters the lungs, it carries oxygen, and it goes to the blood thru the pulmonary cappilaries

refers to the flow of blood to the lungs from the right ventricle to the pulmonary capillaries, oxygen from air enters the blood and the carbon dioxide from the blood goes to the alveoli for release into atmosphere

when there is exchange of gasses between the lungs and the blood, occurs in the respiratory membrane in the lungs

when the oxygenated blood goes to the tissues, oxygen is delivered to the tissues and the carbon dioxide produced by the cells is brought to the vlood to be carried out by the lungs

caused by involuntary contractions of your diaphragm, this causes your vocal chords to close very briefly

absence of breathing

normal breathibg

can only breathe comfortable in upright position (such as sitting in a chair), unable to breathe laying down

attacks of severe shortness of breathe that wakes a person from sleep

increased depth of breathing

increased rate or depth, combination of both

decreased rate or depth

progressive, degenerative disease that destroys alveolar walls

the mucosa of the lower respiratory passages becomes severely inflamed and produces excessive mucis

chronic bronchitis are sometimes called

destruction of alveolar walls and loss of lung elasticity
