Gas Exchange in the Human Body

gas exchange with the blood happens only in the

Part of the upper respiratory tract

Part of the lower respiratory tract

the only externally visible part of the respiratory

the only externally visible part of the respiratory

the nasal cavity is separated from the oral cavity below by a partition called the?

failure of the bones forming the pallet diffuse medially results in breathing difficulty as well as problems with oral cavity function such as breastfeeding and speaking

lighten the skull and acts as a resonant chambers for speech they also produce mucus which drains into the nasal cavities

cold viruses and virus allergens can cause ____? inflammation of the nasal mucosa

difficult to treat and can cause mark changes in voice quality

it is commonly known as throat and it serves as a common passageway for food and air

the muscular passageway about 13 cm long that baguio resembles a short length of red garden house

often called the adenoid is located high in the nasopharynx

tonsil which lies at the base of the tongue

tonsil that is located in the oropharynx at the end of the soft palate

tonsils that protect the openings of the pharyngeal tympanic tubes in the nasopharynx

also called voice box

it routes air and food into the proper channels and place a role in speech

a spoon shaped flap of elastic cartilage

the largest of the hyaline cartilage and is the shield shape which produce anteriorly and is commonly called the adam's apple

sometimes referred to as the guardian of the airway

the slit like passagway etween the vocal fold is called the

part of the mucous membrane of the larynx forms a pair of folds called the__? which vibrate with expelled air that allow us to speak

a procedure in which the air in a person own lungs is used to pop out or expel an obstruction space of food has saved many people from becoming victims of choking

Trachea is lined with a?

it is more common site for inhaled foreign object to become lodge

they are fairly large organ and they occupy the entire thoracic cavity except for the most central area

How many lobes are there in right and left lung?

the walls of the thoracic cavity are lined by the

the surface of each lung is covered with its own visceral serosa called the

slippery serous fluid which allows the lungs to glide easily over the thorax wall during breathing and causes the two plural layers to clean together

inflammation of the pleura can be caused by insufficient secretion of pleural fluid and the plural surface become dry and rough resorting in friction and stopping pain with each breath

Includes in the respiratory zone? which is the only site of gas exchange

serve as a conduit to on from the respiratory zone

What epithelium are in the walls of alveoli?

the final line of defense for the respiratory system is in the alveoli

air must move into an out of the lung so that gas exchange in the alveoli of the lungs are continuously refreshed this also called breathing

an event where in gas exchange between the pulmonary blood and alveoli must take place gas exchange are being made between the blood and the body exterior

an event in respiration wherein an oxygen and carbon dioxide must be transported to and from the lungs and tissue cells of the body via the bloodstream

an event in respiration wherein a systemic capillaries gas exchange occurs between the blood and cells inside the body this time oxygen is unloaded from the blood and co2 is loaded

the use of oxygen to produce atp and carbon dioxide is the cornerstone of all energy producing chemical reactions and occurs in early all cells

The volume within the lung is called?

the amount of air that is inhaled and exhaled during a single breath which is 500 ml of air

the amount of air that can be taken in forcibly above the tidal volume is the? Which is approximately 3,100 ml

the amount of air that can be forcibly exhaled beyond tidal expiration. Approximately 1,200 ml

the air that still remains in the lungs and cannot voluntarily be expelled

the total amount of exchangeable air

air that enters the respiratory tract remains in the conducting zone passageways and never reach the alveoli to participate in gas exchange

sounds occur as air fills the alveoli

sounds that are produced by air rushing through the large respiratory passageway (trachea and bronchi)

inadequate oxygen delivery to the body tissues is called
