Question | Answer |
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 |
