Systole is the phase of the cardiac cycle when the left ventricle of the heart contracts to pump blood to tissues through the aorta.
Explanation:
Because the aorta is incapable of contracting and relaxing with pumping of blood as supposed to, it is unable to accommodate the pulse of blood pressure as the left ventricle contracts and relaxes to pump blood to the tissues. This creates more resistance to blood flow in the aorta as the heart pumps blood especially during systole. The blood pressure in the left ventricle will rise because to pump the same volume of blood, this ventricle will need to pump harder to beat the resistance.

All these are correct I assure you. I took biology last year and thankfully kept my notebook. I had all the information I needed written down. For future reference I recommend taking notes, yeah it sucks but they help A LOT. It's your choice though. :)
Hope this helped. Have a great night!
