Question

mention the stage of cardiac cycle

Answer 1

The cardiac stage consists of series of chamber systole and diastole. ... This will begin a period known as ventricular diastole. Eventually the SAN will stimulate the contraction of the atria to cause atrial systole and ejection of a small volume of blood into the ventricles.

Answer 2

Here's ur answer mate!!
⏩CARDIAC CYCLE: Working of heart includes rhythmic contractions and relaxation of auricles and ventricles.
The contraction phase is called SYSTOLE and the relaxation phase is called DIASTOLE.
A heartbeat includes one SYSTOLE followed by one DIASTOLE.
The sequence of atrial and ventricular events occurring once during each complete heartbeat is termed as cardiac cycle.
The total duration of a cardiac cycle is 0.8 seconds and heart beats 72 times per minute.

⏩GERMINATION: The development of a fruit or flower from a seed.
It's types are:
Epigeal Germination : In this germination cotyledons remain under the soil.
Example of Epigeal Germination is JALAPEÑO.
Hypogeal Germination : In this cotyledons (eventually with time) come out of the soil.
Example of Hypogeal Germination is PEA.
