Respiratory System Flashcards
– from the right side of the heart carry deoxygenated blood to the lungs
pulmonary arteries
oxygen that enters the lungs will be distributed to – in the erythrocytes within the capillaries that branch off the pulmonary arteries that surround the alveoli
hemoglobin
carbon dioxide will – into the alveoli from the pulmonary arteries to be exhaled
diffuse
oxygenated blood will travel to the left side of the heart via –
pulmonary veins
respiratory structures are also responsible for pH regulation, vocal communication, sense of smell and protection from–
infectious agents and particles
respiratory system is essentially a series of – that conduct air into the alveoli located in the lung tissues
tubes
because the respiratory system is a – system it is vulnerable to infection
open
in the nose and pharynx air is warmed to body temperature, – so that gas exchange can occur and filtered
moisturized
nose and pharynx are covered with a – that helps prevent desiccation of the tissues and collects particles and microbes that may enter the system
mucous membrane
nose is particularly well suited to filtration because it has – and hair to help trap substances
cilia
T/F: Filtration in the nose and pharynx will catch all particles
false
during breathing, air will flow through the – which is the opening of the larynx
glottis
voice box
larynx
larynx is made of – and vocal cords that produce sound as they vibrate
cartilage
air flows from larynx > –> lower respiratory tract
trachea
trachea is supported by – of cartilage
C-shaped rings
interior surface of trachea is covered with – and cilia
mucus
trachea > – > bronchioles
bronchi
– surrounding bronchioles can adjust their diameter to meet oxygen demands
smooth muscles
