Since pressure is force per unit area, blood pressure could be thought as the force exerted by the blood to the surface area of your blood vessels. When your blood vessels dilate, it means that they expanded. The result would be faster flow of blood. When this happens, the force of the blood is not any more concentrated on your blood vessels because there is more room available.
Think of a faucet where tap water flows. When you stopper the faucet with your finger, you feel the force of the water. The pressure builds up as manifested by the sound your faucet makes. But when you release your finger, the water rushes through and flows faster. The pressure is released. Therefore, when your blood vessels are dilated, your blood pressure decreases.

Explanation:
Answer:
The statement "oceanic conditions determine human activities" may be interpreted in many ways.
1. Oceanic conditions determine human activities in that the moon cycle influences the tide. As the moon cycle is said to greatly influence human activity, and the tide changes as the moon does, it may also be concluded that the tides have a similar influence on human activity.
2. Weather conditions may also influence oceanic conditions.
a) Hurricanes and typhoons occur in the ocean and if they make landfall, humans are sometimes required to evacuate the location they will affect. The process of evacuation, and the reparations necessary to human civilization afterward, are both examples of oceanic conditions being influential to human activity.
b) Flooding and tsunamis may also result in evacuation, and damage to human civilization.
c) Global warming, which is resulting in the melting of the polar ice caps, contributes to rising sea levels. Rising sea levels are also oceanic conditions that may affect human civilization in the forms of flooding, erosion, and the ocean expanding, and also determine human activities.
