The number of times the heart beats per minute is called heart rate. For a normal adult human it is about 72 times per minute. For infants, it is a higher figure. It also goes up during physical exercise. The contractions and relaxations that the heart chambe..

Rate of Heart Beat - The rhythmic contraction and relaxation of the heart to pump out and receive blood is called the heart beat. The rate of the heart beat varies from species to species. The smaller the animal, the higher is the metaboli..

Pulse is defined as the wave of distension and recoiling felt in the radial artery due to the contraction of the left ventricle which force about 70-90 ml of blood into the already full aort..

The Heart Beat - The heart beat results in electropotential differences spreading over the heart muscles. These follow a specific pattern. Any change in the pattern indicates an abnormality. The pattern can be recorded using an electrocardiograph. The recorded pattern ..

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 the he..

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 heart beat. The heart..

The control of the heart function is by a set of muscles and is, therefore, called myogenic . If the heart is removed from a living mammal and placed in a well oxygenated salt solution maintained at 37 o C, the heart continues to function though at a slower rate..

The circle graph shows the percentage of heart patients under different age groups. Find the age group which corresponds to the outlier value. => 19 - 50 years or 14 - 18 years or 51+ years or 7 - 12 months..

The circle graph represents the percentage of cases of heart diseases under different age groups. What percent of the total cases of heart diseases are recorded in the age group of 19 -50 years? => 7% or 40% or 17% or 8%..
