Which part of the brain constitutes the emotional brain known as the limbic system?

The Limbic System, located between the inner border of the cerebral hemispheres, is sometimes referred to as the 'emotional brain'. It is a ring of structures including the amygdala (associated with fear and anger); the hippocampus (which helps to establish memories); the fornix (which links parts of the limbic system), and the hypothalamus (associated with thirst, hunger, body temperature,sexual function, and water balance). The limbic system is responsible for emotional and instinctive behavior including fear, anger, elation, disappointment, sadness, pleasure, and sexual feelings. It plays a key part in memory, interacts with the cerebral cortex to give conscious awareness of our feelings, and works with the hypothalamus to generate sex drive and arousal. The activities of the body that are governed are those concerned with self-preservation, among them, searching for food and fighting. Included link to a site that will tell you much more.

What is also known as a bleed occurs when a blood vessel in the brain leaks?

It's called cerebral hemorrhage, the previous answer "cerebral aneurysm" refers to a dilation of a portion of an artery, the muscular tissue is thinner than a normal artery, so it's prone to rupture and can cause cerebral hemorrhage. I think the answer they are looking for is a hemorrhagic stroke. Both terms can be used interchangeably.
