Here we have four different questions.
00:03
The very first question that is asking about the blood flow, that is, it flows from the ventricle into the aota because of what? so basically it moves from the ventricle to the aota.
00:21
Here we have to find the reason behind this.
00:25
So whenever we are finding the blood pressure or blood flow, then, basically the blood flows from the region that is higher in pressure to the region which is having the low pressure.
00:49
And so during the ventricular contraction, the pressure, the pressure in the ventricle is higher than in the aorta and hence blood flows from the left ventricle into the aorta and that's why our correct answer here will be the option b that blood pressure in the ventricle is greater than the blood pressure in aorta that's why blood is moving from this to this the next question that is asking about the ventricular filling phase of the cardiac cycle.
01:50
So basically during the process or during the diastrol or the relaxation in the diastolic phase, the cortic valve is closed since the atrial pressure is lower than the aortic pressure and this ventricular feeling begins when there will be the pressure in the left ventricle is lower than the left atrium due to the ventricular relaxation and the material valve opens and so so for this question, our correct answer will be the option c, that is from aortic, arial and ventricular.
03:02
The third question here, that is asking that the blood pressure in the eotia is greater than that in the pulmonary artery because of blood.
03:12
So again, the vascular resistance that it is the resistance to the blood pressure to the blood.
03:31
Flow through the circulatory system.
03:34
And as this resistance increases, the blood pressure increases...
