Which body position describes lying face up?

The body position that describes lying face up is called supine. In the supine position, an individual is lying on their back, which allows for the face to be oriented upwards. This position is commonly used in medical settings for examinations, procedures, and during certain types of imaging, as it provides easy access to the front of the body.

In contrast, the prone position refers to lying face down, while the lateral position means lying on one side, which is not applicable to being face up. The sitting position involves being upright, which also does not relate to being in a supine position. Understanding these terms is essential in various fields, especially in healthcare, where body positioning can impact patient care and assessment.
