Heart - Cardiac Cycle - The heart has an increasing rhythmic activity. It pumps blood by its contraction and relaxation. The contraction of the heart is called systole and the relaxation is called diastole . The contraction and relaxation together constitute ..

The cardiac muscles of the heart have the property of excitability and conductivity. When these muscles are stimulated, they get excited and initiate waves of electric potential called cardiac impulses, which are conducted along the special cardiac muscle fibres on the wall of t..

If the above activity is repeated with another wire or a torch bulb, the current values are found to be different in each case. This shows that the current through the circuit is not decided by the battery but by the component through which it passes. Some materials allow larger current t..

External view of a Mammalian Heart The heart is a 4 chambered muscular pump located inside the chest or the thoracic cavity. It is a mesodermal derivative and is a myogenic heart. The heart is surrounded externally by a thin, transparent 2 layered serous..
