3. Review of the Respiratory System
1. Thoracic cavity encased by a bony
framework of the ribs, vertebrae and
sternum.
2. Lobes of the lungs: Right= 3; Left=2
3. Mediastinum contains the esophagus,
trachea, large blood vessels and the
heart.
4. Two pleural membranes are separated by
enough fluid for lubrication.
6. Airways:
* Infants are nose breathers
I. Upper: (shared by both the respiratory
and alimentary tracts)
a. Sequence of airway muscle activation
is different in breathing and swallowing.
b. Inspiration is short during crying,
coughing, sneezing
7. Airways:
II. Lower Airways
a. Newborn airways have little smooth
muscles
b. Growth of the respiratory system
follows a general growth curve during the
early weeks of life.

and cervical portions of the vertebral
column
8. Respiratory Units: *Gas exchange
a. Infants and young children have less
alveolar surface area for gas exchange

82. Review of the Cardiovascular
System
Cardiac Development and Function
1. The heart is a 4-chambered organ
2. The heart’s location is slightly to
the left of the sternum in the
space between 2 pleural cavities
3. Layers:
Myocardium
Endocardium
Pericardium
Pericardial space
87. Post Natal Development
1. Heart is larger in relation to body size
2. Heart occupies a large space within the
mediastinum
3. LV walls become thicker; LV pressures on
the L side is increased
88. Cardiac Physiology:
The primary function of the heart is to provide
effective oxygen transport to meet the
body’s metabolic need
3 factors that influence stroke volume:
1. Preload- volume of blood returning to the
heart
2. Afterload- resistance against which the
ventricles must pump when ejecting blood
89. 3. Contractility- efficiency of the
myocardial fiber shortening
Frank Sterling’s Law of the Heart:
“The greater the myocardial fiber length or
stretch, the greater is the force of
contraction”
Contractile state (Inotropic State)- vigor
of contraction
91. Congestive Heart Failure
It is the inability of the heart to
pump adequate blood to the
systemic circulation at normal
filling pressures to meet the body’s
metabolic demands
Causes:
1. Volume overload
2. Pressure overload
3. Decreased contractility of the
myocardium
4. High cardiac output demands
103. Therapeutic Management

function:

sodium

3. Decrease cardiac demands
a. Provide neutral thermal
environment
b. Treat existing infections
c. Reduce effort of breathing
d. Provide rest and decrease
environmental stimuli
4. Improve tissue oxygenation
a. Oxygen – humidified
5. Reduce respiratory distress
6. Maintain nutritional status

Primary function:
Digestion and absorption of nutrients
The mechanical functions of digestion are
immature:
1. Swallowing
-Automatic reflex action for the 1st 3
months
116. - No voluntary control unless the
striated muscles of the throat establish
cerebral connections
- Voluntary control begins
approximately 6 week of age
- At the start of the 6th month,
capable of swallowing, holding food in the
mouth and spitting it out
117. 2. Sucking
- Reflexive activity of the newborn
with the muscular action of the tongue to
do a forward thrust
3. Chewing
- Facilitated by the eruption of the
primary teeth
118. The GIT Anatomy and Physiology:
1. Stomach
-round until 2 years old; elongates until
7 years old
- stomach capacity increases with age
2.Intestinal tract
- functional at birth
- salivary amylase to moisten the
mouth and throat
119. - at 2 years old, more enzymes are
excreted to aid in digestion
Functions:
1. Digestion
a. Mechanical/ muscular activity
producing GI motility (movement)
b. Chemical or enzymatic activity
resulting from GI secretions
120. 5 types of GI secretions:
1. Enzymes
2. Hormones
3. Hydrochloric acid
4. Mucus
5. H2o and electrolytes
121. Process of Digestion:
Biting and chewing; mixing of food with
saliva
↓
Salivary amylase begins process of digestion
of complex starches and CHO
↓
Upper esophageal sphincter relaxes
↓
123. ↓
Gastric glands secretes enzymes, HCl acid
and mucus and mix with food
↓
Partially digested food and watery gastric
secretions are delivered to the small
intestines
↓
Absorption of nutrients in the small
intestines
124. B. Absorption- occurs in the small intestines
The large intestines completes the process
of absorption
C. Elimination of waste products
*Bacteria affects the color and odor of stool
and gas formation:
a. Brown color
b. Bleeding
1. Tarry black/ melena
2. Bright/ dark red

exernal anal sphincters relaxes following
distension of the rectum by feces
*Frequency of defecation is increased in
newborns
128. Pathophysiology:
Absence of ganglion cells in the affected
areas of the intestine nervous system
stimulation
↓
Lack of independent enteric nervous system
stimulation
↓
Loss of rectosphincteric reflex
↓
129. ↓ ↓
Decreased ability Absence of
of the internal peristalsis
sphincters to relax
(Contraction of abnormal
bowel)
