GNUR 293 - Exam 2 Review/GNUR 293 - Exam 2 Review. Acid-Base Homeostasis and Imbalances Describe how volatile and nonvolatile acids are buffered and/or removed from the body, from first to last to respond, in order to maintain homeostasis and maintain a blood pH of 7.35-7.45. Describe the balance (ratio) of HCO3- (bicarbonate) to H2CO3 (carbonic acid). What imbalances occur when that ratio is altered? - 1-part carbonic acid and 20 bicarbonate acid - Bicarbonate is most important, con...

GNUR 293 - Exam 2 Study Guide/GNUR 293 - Exam 2 Study Guide Acid-Base Homeostasis and Imbalances Describe how volatile and nonvolatile acids are buffered and/or removed from the body, from first to last to respond, in order to maintain homeostasis and maintain a blood pH of 7.35-7.45. o Volatile acids: undergo vaporization rapidly. Carbonic acid is a volatile acid that forms inside our body from carbon dioxide and is excreted via the lungs. o Nonvolatile acids: Cannot undergo vaporiza...

GNUR 293 - Exam 4 Study Guide/GNUR 293 - Exam 4 Study Guide. Respiratory Function and Alterations in Gas Exchange How do central and peripheral chemoreceptors affect breathing? Central chemoreceptors: - are located in the medullary center and respond to changes in CO2 and ph. - This is our NORMAL stimulus to breathe and is caused by a small increase in arterial carbon dioxide tension. This small increase in PaCO2 tells the body to BREATHE. Peripheral chemoreceptors: - are locat...

GNUR 293 - Exam 3 Study Guide/GNUR 293 - Exam 3 Study Guide. Alterations in Blood Flow How do pressure, resistance, velocity, turbulence, compliance and Starling’s forces impact blood flow? Pressure: Blood moves from high pressure (systemic arteries) to low pressure (veins) More pressure = increased flow Increased Blood = Increased Pressure Resistance: resistance that must be overcome to push blood through the circulatory system; movement of blood through the vascular system is...
