1st Periodic Test Flashcards
human respiratory is subdivided into two parts which is?
upper respiratory tract and lower respiratory tract
Process where exchanges of gasses, particularly oxygen and carbon dioxide, occur.
Respiration
gas exchange between blood and cells
Internal Respiration
Process that delivers oxygen to where it is needed and removes carbon dioxide
Breathing
gas exchange between lungs and blood
External Respiration
transport of carbon dioxide and oxygen
Transport
Respiratory gasses are obtained and expelled through inhalation and exhalation
Breathing
primary entrance of air into the body
Nasal Cavity
tube that connects the nasal cavity to the larynx
Pharynx/Throat
which traps impurities from the air.
Cilia
Parts of the pharynx
nasopharynx, oropharynx, laryngopharynx
connects the pharynx and larynx to the lung opening
Trachea/windpipe
part of the throat that contains the vocal folds
Larynx
branching tubes to the lungs
Bronchi
secondary or smaller tubes branching from the bronchi
Bronchioles
Actual site of gas exchange, tiny sacs whitin our lungs
Alveoli
A dome-shaped muscular structure located between the thoracic and abdominal cavity.
Diaphragm
A pair of large, spongy organs where exchange of gases occurs.
Lungs
Flow of air during inhalation
Nasal cavity» pharynx» larynx» trachea» bronchi» bronchioles» alveoli
msucular insertion in between the ribs forming the chest wall
intercostal muscle
breathing in, entrance of oxygen rich into the lungs
Inhalation
breathing out, exit of carbon dioxide from the lungs
exhalation
viral infection of the nose and throat
common colds
Usually caused by rhinoviruses
common colds
infection of the alveoli in the lungs, causing it to be filled with pus making it hard to breathe
Pneumonia
viral disease that mainly affects the lungs.
Tuberculosis
caused by viruses, typically influenza
acute
inflammation of the lining of your bronchial tubes; can either be acute or chronic
Bronchitis
4 chambers of the heart
Right Atrium, Left Atrium, Right Ventricle, left Ventricle
cigarette smoking. Air pollution and dust or toxic gases in the environment
chronic
a type of chronic obstructive pulmonary disease where in the alveoli become damaged and stretched
Emphysama
The airways become narrow, and swelling is evident. Extra mucus is also produced.
asthma
hallow organ that pumps blood all over the body
heart
Components of the Circulatory System
Heart, Blood, Vessels
connective tissue that carries and transport oxygen
blood
network of pathways through which blood travels
vessels
heart is enveloped by
pericardium
the upper chambers
Atria
the lower chambers
Ventricle
These are flaps that serve as one-way inlets that prevent blood overflow in the heart.
Cardiac valves
4 valves in the heart
mitral, tricuspid, pulmonary, and aortic valve
The 3 types of blood vessels are the
arteries, veins, and capillaries
the biggest artery.
aorta
biggest veins
vena cava
blood vessels that transport oxygenated blood away from the heart
Arteries
blood vessels that carry deoxygenated blood towards the heart
veins
very tiny blood vessels
capillaries
