Explanation:
Four bones of the skull contain paired air spaces called the paranasal sinuses that help to lighten the heavy load of the head.
<h3>What is Paranasal Sinus?</h3>
The paranasal sinuses are air-filled, bony spaces located next to the nasal passages in the face bones of the skull. They grow via slowly expanding pneumatized cells that erupt from the nasal cavity. The term is typically used in everyday speech to refer to the hollow, air-filled spaces in front of the human skull. There are four pairs of sinuses in humans. There are now eight sinuses in all. These four pairs of sinuses are together referred to as paranasal sinuses since they are all joined to the nasal cavity.

Answer:
Blood pressure is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in the large arteries.
Explanation:
Blood pressure is measured in units of millimeters of mercury (mmHg). The readings are always given in pairs, with the upper (systolic) value first, followed by the lower (diastolic) value. diastolic blood pressure of 88 mmHg. When your heart beats, it squeezes and pushes blood through your arteries to the rest of your body. This force creates pressure on those blood vessels, and that's your systolic blood pressure. A normal systolic pressure is below 120. A reading of 140 or more means you have high blood pressure.
