ball and socket joint
type of joint permits the widest range of motion—flexion, extension, abduction, adduction, and rotation. Examples: joints at the shoulders and hips
35
hinged joint
joints (such as those in the elbow, knee, and finger) permit flexion and extension.
36
pivot joint
allows for a turning motion; it includes the joints between the head and neck at the first and second cervical vertebrae and those in the wrist.
37
gliding joint
where one bone slides across another to the point where surrounding structures restrict the motion. Gliding joints connect the small bones in the hands and the feet.
38
saddle joint
This joint is shaped to permit combinations of limited movements along perpendicular planes. For example, the ankle allows the foot to turn inward slightly as it moves up and down.
39
condyloid joint
modified ball-and-socket joint that permits limited motion in two directions. In the wrist, for example, it allows the hand to move up and down and side to side, but not to rotate completely.
40
skeletal muscle
can be contracted and relaxed by will of the individual. This type of muscle makes possible all deliberate movement, such as walking, chewing, swallowing, smiling, frowning, talking, or moving the eyeballs
41
smooth muscle
made up of large fibers that carry out the automatic muscular functions of the body
42
cardiac muscle
a special kind of involuntary muscle particularly suited for the work of the heart. It has the property of automaticity
43
automaticity
can generate an impulse on its own, even when disconnected from the central nervous system
44
respiration
the process of moving oxygen and carbon dioxide across membranes, in and out of the alveoli, capillaries, and cells

Inadequate breathing
Rates that are either too slow or too fast as compared to what is normal for the patient
Irregular pattern of breathing resulting from an illness or injury
Diminished or absent breath sounds, indicating an inadequate volume of air being breathed in and out
Unequal chest expansion, indicating a chest wall injury that could reduce the tidal volume
Inadequate chest expansion, indicating a poor volume of air being breathed in (referred to as shallow breathing)
Pale or bluish mucous membranes or skin that may also be cool and clammy, indicating poor oxygen exchange (respiration and oxygenation)
Use of accessory muscles, identified by retractions above the clavicles, between the ribs, and below the rib cage and use of the muscles in the neck during breathing, especially among infants and children, indicating an increased work effort to breathe
Nasal flaring, especially in children, indicating an increased work effort to breathe
“Seesaw” breathing in infants (the chest and abdomen move in opposite directions)
Head bobbing, where the head bobs upward on inhalation and downward toward the chest on exhalation, indicating severe respiratory fatigue
Agonal respirations (occasional gasping breaths) that may be seen just before death
Grunting, especially in newborns, heard at the end of inspiration or the beginning of exhalation
57
Circulatory System functions
Providing a medium for perfusion of cells with oxygen and other nutrients and removal from the cells of carbon dioxide and other waste products
Transporting blood to cells and the alveoli for gas exchange
Serving as a reservoir to house blood

73
Pulmonary Artery
originate at the right ventricle of the heart, carry oxygen-depleted blood to the lungs, where the blood is oxygenated and returned to the heart for circulation throughout the body
74
Venae Cavae
carry oxygen-depleted blood back to the right atrium, where it begins circulation through the heart and lungs
75
Pulmonary Vein
carry oxygen-rich blood from the lungs to the left atrium
76
Plasma
carries blood cells and transports nutrients to all tissues. Transports waste products to organs where they can be excreted from the body. A minute amount of oxygen is dissolved in plasma and transported throughout the body. A larger amount of carbon dioxide is carried by the plasma to the lungs for elimination.
77
platelets
essential to the formation of blood clots, necessary to stop bleeding.
78
red blood cell
give the blood its color, carry oxygen to the body cells, and carry carbon dioxide away from the cells. Hemoglobin, located in the cytosol inside the red blood cell is responsible for carrying oxygen molecules and carbon dioxide.

81
diastolic BP
exerted against the walls of the arteries when the left ventricle is at rest, or between contractions
82
hydrostatic pressure
force exerted on the inside of the vessel walls because of the blood pressure and volume; may cause the blood in the capillaries to force fluid through the capillary wall.
83
Perfusion
delivery of oxygen, glucose, and other nutrients to the cells of all organ systems and the elimination of carbon dioxide and other waste products that result from the constant adequate circulation of blood through the capillaries

101
Stomach
hollow organ
breaks down food,
LUQ
102
Pancreas
Solid Organ,
secretes pancreatic juices that aid in the digestion of fats, starches, and proteins. The islets of Langerhans, located in the pancreas, produce the insulin that regulates the amount of sugar in the bloodstream.
LUQ
103
Liver
Solid Organ
produces bile, which aids in the digestion of fat. It stores sugars until they are needed by the body. It also produces components necessary for immune function, blood clotting, and the production of plasma.
RUQ
104
Spleen
Solid Organ
helps in the filtration of blood and, because it contains a dense network of blood vessels, serves as a reservoir of blood the body can use in an emergency such as hemorrhage.
LUQ
105
Gallbladder
Hollow Organ

RUQ
106

hollow organ
made up of the duodenum, jejunum, and ileum. It receives food from the stomach and secretions from the pancreas and liver. Digestion of food continues in the small intestine, where food is completely broken down into a form that can be used by the body.
107
Large Intestine/colon
Hollow Organ
parts of food that cannot be absorbed by the body are passed as waste products from the small intestine to the large intestine. As these waste products move through the large intestine, their water is absorbed.
