23、e feedback: There are situations where the initial response produces further change in the same condition. This is self-perpetuating and is called positive feedback.2 Antiporter: The carrier protein couples the movement of molecules in opposite directions, then it is called anantiporter and the mole
24、cules are said to be counter-transported.3 Resting potential: Under the quiet or calm conditions (without any stimuli), the membrane displays the potential difference between inside anodutside the cell.4 Mean Arterial Pressure: MAP= Diastolic Pressure + 1/3 Pulse Pressure, about 100mmHg (13.3kPa).5
25、Surfactant: The fluid lining the alveoli contains material, a phospholipid secreted by typeH pn eumocytes which lowers the surface tension of alveoli and cause surface tension to change with volume.6 Basic electrical rhythm (BER): The basic electrical rhythm (BER) is a slow spontaneous depolarized w
26、ave in the GI tract and BER of smooth muscle cells form the basis (action potential) of stomach contractions.7 Respiratory quotient: RQ=Mol number of producing CO2 in body per unit time / Mol number of consumptive O2 in body per unit time.8 Renal reabsorption: Salt and water are reabsorbed in differ

29、ion: (50 Points)1 Please an swer comp onents of a typical ECG trace and each meanin g(8 Poin ts) Three major comp onents of an ECG are P wave, QRS complex wave.P wave: atrial depolarizati onQRS complex: depolarizatio n of ven triclesT wave: repolarizati on of ven triclesPR in terval is the in terval
30、 from the beg inning of atrial activati on to the beg inning of ven tricular activati on.QT interval is the required for ventricular depolarization and repolarization.2 What are determi nants and regulation of RBF? (8 Poi nts)RBF is determ ined by systemic arterial blood pressure and renal vascular
31、resista nee. RBF dem on strates autoregulatio n.Autoregulatio n invo Ives affere nt n ot effere nt arterioles.Autoregulatio n is expla ined either by the myoge nic hypothesis or tubuloglomerular feedback.3 How are pulmo nary ven tilation In flue need by PO 2 ,PCO2 , and pH? (10 Poi nts)Two groups of
32、 chemoreceptors, medullary and peripheral, send affere nt in formati on to the medulla and in flue nee the depth and rate of respirati on.Medullary chemoreceptors are sen sitive to pH and in crease ven tilatio n whe n pH falls. Peripheral chemoreceptors are sensitive to pH O2 J , and(P2 fwith PCO2 b
33、eing most effective.Sen sitivity of the peripheral chemoreceptors is in flue need by pH,. PO, and PCQ.4 What are typical and common patterns of motility in different parts of gastrointestinal tracts? (8 Points)The common patterns of motility in different parts of gastrointestinal tracts is peristals
34、is.The typical patterns of motility at stomach is receptive relaxation for store of food.The typical patterns of motility at small intestine is segmentation for turning food into smaller particles and helping absorption.The typical patterns of motility at large intestine is mass movement for pushing
35、 the contents in the colon into the next downstream segment.5 What are functions of thyroid hormones ? (8 Points)(1) Because T3 acts by inducing DNA transcription, its effects on tissue are theresult of protein synthesis, primarily the synthesis of enzymes.(2) Thyroid hormones are required for norma
36、l growth throughout life.(3) Thyroid hormones affect basal metabolic rate, metabolism, the cardiovascular system, and the nervous system.(4) Symptoms of thyroid hormone excess or deficiency can be predicted fromtheir normal effect.6 How does the human bodys reflex response to cold? (8 Points)When a
37、fall in core body temperature is detected by the hypothalamus, the reflex compensation involves reducing heat loss and generating more heat by increasing metabolic rate and through shivering.(1) Objective of body is to reduce heat loss and increase heat production.(2) Reducing heat loss occurs by de
38、creasing skin blood flow and through behavioral responses.(3) Increasing heat production occurs through metabolic effects of thyroxin andcatecholamines as well as by shivering.(4) Sustained exposure to extreme cold depresses hypothalamic temperaturecontrol mechanism and produces dilation of skin vasculature.
