Gaseous Exchange in the Alveolus of Man The capillaries lining the alveoli have impure blood which has low concentration of oxygen. So, the oxygen from the air easily diffuses into the blood through the thin barrier of the alveolus wall. Similarly since the concentration of carbon dioxide is q..

Fibrillation is abnormal and asynchronous contraction of the heart muscles. This reduces the proper effectiveness of heart pumping. Atrial fibrillation is irregular and faster contract ions of atria. It may occur in myocardial infarction and in rheumatic hea..

>d) Increases the conductivity of the cardiac muscle and bundle of His thermal regulation Adrenaline secreted by the adrenal medulla of adrenal gland accelerates the rate of heart beat during emergency conditions. Noradrenaline increases the heart beat during normal ..

In a hospital, especially in the Intensive care unit (ICU), where seriously ill patients are treated, monitoring of the patients heart rate, blood pressure, temperature, oxygen level in blood etc. is very important. Electronic biomedical equipments continuously monitor the patients vital ..

. These impulses are transmitted from the electrodes to a recording pen that graphs the impulses as a series of up and down waves called deflection waves. 3 recognisable waves accompany each cardiac cycle. The first called the P wave, is a small upward wave. It indicates atrial depolarisation - the..
