destroying cells) - Answer-attachment
penetration
biosynthesis
maturation
lysis
Attachment phase of lytic cycle - Answer-phage interacts w specific bacterial surface
receptors
Penetration phase of lytic cycle - Answer-viral DNA enters host cell

bones
-cranial sutures dont fuse til adult
-hearing ranges
-BBB is not fully developed !!!
-unable to control their head
what are main HEENT differences btn infant and adult - Answer--smaller airways
-bb's = nose breathers til 4-6mo
-lrger tongue and smaller oral cavity
-trachea is more cartilaginous and soft
-tonsils may be enlarged
-larynx is higher and more anterior
-short trachea
what does the main differences of HEENT in infants vs adult mean? - Answer--greater
risk of airway obstruction
-nose breather = nares must be patent
-tongue is more likely to obstruct airway
-trachea nature (being shorter) is succeptible to collapse and be obstructed
-endotracheal tube can be hard to insert due to enlarged tonsils
-intubation can be harder due to larynx position and epiglottis

metabolic rate
-higher HR
-Blood vol is larger, but absolute vol is smaller
-smaller vessels, lrg heart compared to small body
-under 6mo SV cannot be adjusted (everything is dependent on inc HR)
-minimal # of myocytes
-drop in urine output = issues w heart
what does main cardiovasc differences for infants vs adults mean - Answer--leads to
rapid desat
-blood loss is very closely monitored
