Unit 1 Questions 1- 3 Figure 1 The sources of blood glucose in a human body during a normal day of 24 hours are shown in the above figure. Glucose is primarily derived from glycogenolysis occurring between meals. Glucose is chiefly sourced from the dietary intake for few hours following the principal meals of the day. Late at night‚ gluconeogenesis becomes the predominant source of glucose. 1 Glycogenolysis decreases after midnight because A C 2 gluconeogenesis takes place. hepatic glycogen is

Excretory System Review Main Concepts: Describe the major gross anatomical structures of the excretory system. Kidneys: receive about 25% of the cardiac output; produce urine (a fluid containing water‚ ions‚ and small soluble compounds) Ureters: receive urine from the kidneys and conduct it to the urinary bladder. Urine movement involves a combo of gravity and the peristaltic contractions of smooth muscle in the walls of the ureters Urinary Bladder: receives and stores urine prior to elimination

Situation: Two patients in their 70s present to the office at different times today‚ each with documented heart failure: one diastolic and the other systolic‚ and both are hypertensive. First‚ discuss the difference between systolic and diastolic heart failure‚ providing appropriate pathophysiology. ACEI/ARBs are the only medications prescribed for CHF that have been found to prolong life and improve the quality of that life. EXPLAIN the mechanism of action of ACEI/ARBs and how they affect morbidity

typically involves elevated levels of epinephrine and glucocorticoids Alarm reaction- mediated by norepinephrine from the sympathetic nervous system‚ and epi from the adrenal medulla. They prepare body for flight or fight. Angiotensin and aldosterone levels also increase. Angiotensin raises BP‚ aldosterone promotes sodium and H2O conservation‚ which helps offset possible losses by sweating and bleeding. Stage of Resistance- If stressful situation isn’t resolved before the glycogen is gone‚ it enters

diuretics are often the first choice in high BP medications. Thiazide diuretics include: hydrochlorothiazide (Microzide)‚ chlorthalidone and others. Diuretics or calcium channel blockers may work better for African-Americans and older people than do angiotensin-converting enzyme (ACE) inhibitors alone. Beta blockers are another type of medication; they reduce the workload on your heart and open your blood vessels‚ causing your heart to beat slower and with less force. Beta blockers include: acebutolol

------------------------------------------------- Water and Electrolytes Water constitutes 50-55% of a woman’s body weight and 55-60% of man’s weight. Water gives structure and form to the body‚ helps maintain body temperature‚ and also creates the necessary environment for cell metabolism. There are two compartments of body water‚ extracellular and intracellular fluid. Extracellular fluid (ECF) is water found outside of cells. Making up approximately 20% of total body weight‚ the ECF consists

Arterial blood pressure is "normal" when the systolic pressure is 90-119 mmHg and the diastolic pressure is 60-79 mmHg. When the arterial pressure is ≥120/80 mmHg‚ a person is considering being hypertensive [1-3]. According to U.S. national guidelines (JNC 7 Report and JNC 8 Report)‚ the following represents different stages of hypertension: Classification Systolic (mmHg) Diastolic (mmHg) Normal <120 <80 Prehypertension 120-139 80-89 Stage 1 140-159 90-99 Stage 2 >160 >100 Treatment of Hypertension
