<human>: The Public Broadcasting Service in the U.S shows several cooking show that are based out of the U.K. I've noticed some terminology differences regarding ovens and am trying to sort them out in my mind.

In the U.S., most electric ovens have two heating elements. The one on top is called the broiler and the one on the bottom is called baking or roasting element. When we (Americans) set the oven temperature to say 175c/350f, the bottom element is the only one that heats up and is used to maintain the temperature setpoint. We call this baking or roasting. 

When the top element is used, it's usually on full blast and used for relatively short duration cooking and is called broiling. I've noticed U.K terminology referring to grilling in the oven. That one kind of confuses me because  we usually refer to grilling as an open flame under a grill. That type of cooking is generally done outdoors. The one notable exception being the grilled cheese sandwich which is done on a griddle or in a pan.

Give me the gist of the text in a nutshell
<bot>: How do ovens in the U.K. work and what is the terminology used to describe the ways of cooking in them.
