True or false? if aortic pressure increased above normal values, the left ventricle would need to generate even more pressure to ensure blood flow through the systemic circuit.

True

Explanation:

When a patient presents stenosis, that means that the aortic valve is smaller, so the pressure that goes to the aorta will increase. Since this valve is in the left part of the heart, and the left ventricle also is located in the same side, the ventricle needs to pump with more force to make up for the blood pressure.

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.
