Identify the correct sequence of the cardiac cycle. (i) Blood through the pulmonary vein and vena cava enters in left and right atria respectively. (ii) AVN generates action potential for the ventricles. (iii) SAN bring about atrial systole . (iv) Ventricular systole pushes blood away from the heart .

Read the following statements (i - iv) about human heart : (i) Human heart is myogenic and our body has the ability to alter the heart rate , cardiac output but not stroke volume. (ii) P - wave in ECG marks the atrial systole . (iii) Adrenal medullary hormones acts on SA node and increases heart rate. How many statement is/are correct form the above ?

Read the following four statements (1-4) (1 ) The second heart sound is DUB, which is associated with the closure of bicuspid and tricuspid valves . (2) The duration between consecutive second and first heart sound is 0.5 second in a cardiac cycle . (3) The heartbeat of a human increase when the adrenaline hormone in injected into it. (4) The atrial systole in a cardiac cycle increase the flow of blood into the respective ventricle by about 70% . How many of the above statements are incorrect ?

mark the true and false statements a. SAN generates as action potential which stimulates atrial systole. b. ECG is an electrical representation of the graphical activity of the heart during a cardiac cycle. c. The cardiac output of a normal man will be much lesser than an athlete. d. The wall of right ventricle is much thicker than the left ventricle e. In pisces the two separate circulatory pathways are present, hence they have double circulation. f. The clsoed circulatory pattern is considered to be more advantageous than open circulatory pattern. g. Glucose is absorbed by simple diffusion through lymph in lacteales present in the intestinal villi. h. The SAN can generate the maximum number of action potential i.e. 140-150 mi n^(-1) in neonates, and is responsible for initiation and maintenance of the rhythmic contractile activity of the heart. i. Angina can occur in any age but more common among the neonates and infants. j. heart failure is sometimes called congestive heart failure because congestion of the blood vessels is one of the main symptoms of this disease.

Isovolumetric systole is duration between

The duration of atrial diastole in a normal cardiac cycle is

A : Isovolumetric systole of a normal cardiac cycle is responsible for the opening of semilunar valves causing the blood flow into aortic aorta and pulmonary aorta. R : During isovolumetric systole, intraventricular pressure increases as semilunar and AV valves are closed and ventricles are contracting .

Ventricular systole is stimulated by

During ventricular systole

During systole of heart
