Random Unit 6 (2) Flashcards
Known as visceral pericardium, Outermost layer of the heart
Epicardium
Secretes serous fluid preventing friction as the heart beat
Epicardium
Middle layer of the heart, Composed of cardiac muscle
Myocardium
Contracts to propel blood into the next heart chamber or out into the blood vessels of the body
Myocardium
Innermost layer of the heart
Endocardium
Protective lining of the heart chambers and valves of the heart
Endocardium
Deoxygenated blood returns to the
Right atrium and flows into the Right ventricle and is then pumped to the Respiratory system
Oxygenated blood leaves
The Lungs to flow into the Left atrium moves into the Left ventricle and then is pumped to aLL parts of the body
Frequency of the cardiac cycle and is expressed in beats per minute
Heart Rate
Amount of blood pumped out of the heart in 1 minute and is determined by heart rate (HR) and stroke volume (SV).
Cardiac Output (CO)
CO =
HR × SV
Which blood vessel returns oxygenated blood to the heart
Pulmonary Vein
Venous blood returning from the body enters which chamber of the heart first
Right Atrium
Nose, Nasal Cavity, Sinuses, and Pharynx
Upper Respiratory Tract
Larynx, where the vocal cords are located, the trachea, and the branches of the respiratory tree. The trachea branches into the right and left main bronchi. The bronchi divide repeatedly into smaller bronchioles and alveolar ducts. The bronchioles and ducts terminate in the alveoli.
Lower Respiratory Tract
The movement of air into and out of the lungs is known as
Ventilation
Located in the brain and control the rate of respiration
Respiratory Centers
State in which oxygen is not available in sufficient amounts at the tissue level to maintain adequate homeostasis
Hypoxia
Increased pulse and respiratory rate
Hypoxia
Late sign of hypoxia
Cyanosis
Breaths less than which number per minute are termed bradypnea
12
Myopia
Nearsightedness
Hyperopia
Farsightedness
Facilitates heat loss through sweating and vasodilation of blood vessels
Anterior hypothalamus
Reduces heat loss through vasoconstriction of blood vessels
Posterior hypothalamus
Diaphoresis
Excessive Sweating
Afebrile
Without Fever
Axillary temperatures are usually 1°F
Less
Rectal temperatures are approximately 1°F
Higher
Pyrexia
Fever
Loss of sensation
Anesthesia
Increased sensitivity to sensation, particularly to something light
Hyperesthesia
Decreased sensitivity to sensation, especially touch
Hypoesthesia
Paresthesia
Burning, pain or electric shock
Minimum output of urine for adult
30-50ml/Hour
Braden scale more than what is minimal risk
18
Best response for Glasgow coma scale
18
8 or less on the Glasgow scale is
Comatose
