سوال : The first sound of heartbeat is made after what action

جواب :

It is caused by the sudden block of reverse blood flow due to closure of the atrioventricular valves, i.e. mitral and tricuspid, at the beginning of ventricular contraction, or systole. When the pressure in the ventricles rises above the pressure in the atria, venous blood flow entering the ventricles is pushed back toward the atria, catching the valve leaflets, closing the inlet valves and preventing regurgitation of blood from the ventricles back into the atria. The first sound results from reverberation within the blood associated with the sudden block of flow reversal by the valves]].

The first heart sound is produced by the turbulant flow against the closed AV valves .

First heart sound is caused by atrioventricular valves - Bicuspid/Mitral and Tricuspid .

سوال : what make the sun ?

جواب :

The Sun was created in a cloud of gas and dust 4.6 billion years ago. Gravity brought clumps of the cloud together, while the temperature and pressure at the centre rose until it became hot enough for nuclear fusion to take place

The Sun is a mixture of gases - approximately 75% hydrogen and 25% helium. These proportions are changing over time as reactions in the Sun's core convert hydrogen into helium. It’s the energy released by these reactions which produces the Sun's heat. At the Sun's core, where the temperature is 15 million kelvin, the gases are compressed by gravity to a density many times that of lead. While this gravity tries to shrink the core, the Sun is kept in equilibrium by the counterbalancing force of the energy released as the hydrogen burns

Away from the core, both the density and temperature of gases decrease quite quickly. Heat radiates outwards through a 'radiative zone' until it reaches the photosphere

The photosphere - which you could think of as the surface of the Sun - even though it’s not solid - lies beyond the radiative zone. It is a layer about 500 kilometres (300 miles) thick, where the temperature is a 'cool' 5 800 kelvin.
