23、e 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 molecules are said to be counter-transported.

24、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 Surfactant: The fluid lining the alveoli

25、contains material, a phospholipid secreted by typeH pneumocytes 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 wave in the GI tract and BER of smooth musc

29、typical ECG trace and each meaning(8 Points)Three major components of an ECG are P wave, QRS complex,T wave.P wave: atrial depolarizationQRS complex: depolarization of ventriclesT wave: repolarization of ventriclesPR interval is the interval from the beginning of atrial activation to the beginning o

30、f ventricular activation.QT interval is the required for ventricular depolarization and repolarization.2 What are determinants and regulation of RBF? (8 Points)RBF is determined by systemic arterial blood pressure and renal vascular resistance.RBF demonstrates autoregulation.Autoregulation involves

31、afferent not efferent arterioles.Autoregulation is explained either by the myogenic hypothesis or tubuloglomerular feedback.3 How are pulmonary ventilation Influenced by PO 2 ,PCO2 , and pH? (10 Points)Two groups of chemoreceptors, medullary and peripheral, send afferent information to the medulla a
