No.
No, vasoconstriction would increase peripheral resistance. When blood vessels constrict, the diameter of the blood vessels becomes smaller, which increases resistance to blood flow. This can lead to an increase in blood pressure.
Blood coagulates faster when cold is applied. Cold temperatures cause blood vessels to constrict, reducing blood flow and promoting coagulation. Heat, on the other hand, can increase blood flow and delay the coagulation process.
Factors that influence resistance to blood flow include the diameter of blood vessels (smaller diameter increases resistance), length of the vessels (longer vessels increase resistance), blood viscosity (thicker blood increases resistance), and turbulence within the blood vessels (increased turbulence increases resistance).
Conditions that can increase the intensity of the S2 heart sound include high blood pressure, pulmonic stenosis, aortic stenosis, and conditions that lead to increased blood flow through the pulmonary or aortic valves.
Blowing up a balloon can temporarily increase blood pressure because it requires a sustained increase in intrathoracic pressure, which can affect blood flow and heart function. However, this effect is usually short-lived and not a significant factor in affecting overall blood pressure.
An increase in heat causes blood vessels to dilate, which increases blood flow in the body.
Yes, heat can increase blood flow in the body by dilating blood vessels and improving circulation.
No, applying ice causes vasoconstriction, which reduces blood flow to the area. Ice helps to decrease inflammation and swelling by restricting blood flow. Heat, on the other hand, can increase blood flow and promote healing in some situations.

If the foreskin cannot be pulled back into place treatment should be sought. If the blood flow to the penis is restricted then emergency treatment is required and if the foreskin cannot be pulled back a surgical cut to the trapped foreskin may be needed
Except in cases of massive blood loss, it's not the job of the vessels to increase or decrease blood flow, but of the capillary beds.
Caffeine can slightly increase heart rate and blood pressure and can cause restlessness, anxiety, and make it difficult to sleep. However, caffeine has no effect on the foreskin or the rest of the penis.

Is increase in blood pressure in the capillaries
Some medications increase blood flow, like inotropics. Others, like vasoconstrictors, may decrease blood flow.
