Exam 2

Chapters 7-9

Aerobic metabolism Breakdown of molecules through reactions that produce energy in the presence of oxygen.
Anaerobic metabolism Breakdown of molecules in the cells without the presence of oxygen.
Perfusion Delivery of oxygen and other nutrients to all organ systems and the elimination of co2 and other waste products.
Effects of Beta1 Increased heart rate and force of cardiac contractions, and speed up electrical impulses traveling down the hearts conduction system.
Effects of Beta2 Causes smooth muscle to dilate, especially in the bronchioles.
Lateral recumbent position Patient is lying on the left or right side.
Anterior and Posterior Toward the front, toward the back.
Hypoxic Drive Aterial co2 is elevated, chemoreceptors become insensitive to changes that stimulate ventilation. Instead of co2 increase, chemoreceptors stimulate for ventilation and rely on a decrease in o2.
The nervous system has 2 parts The CNS and the PNS
Compensation of a decrease in cardiac output If a drop of blood left the left ventricle, in 1 minute it should be back at the left ventricle.
Segments of spinal column Cervical (C1-C7) Thoracic (T1-T12) Lumbar (L1-L5) Sacral (S1-S5) and coccyx.
Voluntary muscle Contracted and relaxed by will of the individual.
Involuntary muscle Large fibers that carry out the automatic muscular functions of the body through rhythmic wavelike motions.
Line that divides the the body into left and right halves Sagittal plane
FiO2 Fraction of inspired oxygen
Artery leading to the lower extremities Femoral and Dorsalis pedis
Artery leading to the head Carotid
Infants are what kind of breathers? Nose
Normal body temperature for infants 98-100 degrees Farenheit
Ertythrocytes Carries oxygen to the body cells and carry co2 away from the cells
Leukocytes Defend against infection
Thrombocytes Essential to the formation of blood clots which stop bleeding.
Plasma Carries blood cells and transports nutrients to all tissues. Also transports waste products to organs so they can be excreted.
Proximal and distal Near the point of reference and far from the point of reference.
Vessels that carry deoxygenated blood Pulmonary arteries
Alveolar respiration Exchange that serves to oxygenate blood and eliminate carbon dioxide in the lungs.
Leaf structure in the upper airway Epiglottis
Brain part that controls all vital functions Cerebrum
Age group with a high suicide rate because of terminal illness and isolation Late adulthood
Normal fertilization takes place in? Ovaries, fallopian tubes, uterus
Main function of gallbladder Acts as a reservoir for bile
Main function of kidneys Filter waste from the bloodstream and help control fluid balance
Gland that sits on top of the kidneys Adrenal glands
Central chemoreceptors Located in the brain stem
V/Q ratio Relationship between amount of ventilation the alveoli receive and the amount of perfusion through capillaries surrounding the alveoli.
The leading cause of death for people aged 20-40 Accidents
A child with no spinal injuries can what? Be held and assisted by the caregiver while the EMT is doing the assessment.
A critical drop in blood pressure is a threat to the body because it directly impairs what? Perfusion
Primary function of the circulatory system Supply the body with oxygen and remove waste
Components of the circulatory system Heart, vessels, containers, blood, pumps.
Gas always moves from a (blank) concentration to a (blank) concentration High and low
Age group that commonly has a perceived sense of invulnerability Adolescents
A drop of blood through the heart Vena cava-right atrium-tricuspid-right ventricle-pulmonary valve-pulmonary artery-lungs-pulmonary vein-left atrium-bicuspid-left ventricle-aortic valve-aorta-arteries
Significance of bulging/depressing fontanels Swelling, dehydration
If cellular perfusion is critically impaired, what effects would it have on the blood pressure? It would become toxic
Capillary membranes are (blank) so gas exchange can pass back and forth Permeable
