The muscle below the lungs that contracts to facilitate breathing.
diastolic blood pressure
The pressure in an artery when the heart is at rest.
diencephalon
The part of the brain between the cerebrum and the brainstem that contains the thalamus and hypothalamus.

The process of chemically breaking down food into small parts so that absorption can occur.
disease
An abnormal condition in which the body’s steady state (homeostasis) is threatened or cannot be maintained.
division
The separation of the peripheral nervous system into two parts.
division
The separation into parts or sections.
duodenum, jejunum
The sections of the small intestine where most digestion and absorption occurs.
elder speak ,
A style of speech used by younger people when communicating with older adults that resembles baby talk and contains features such as slower rate, patronizing tone, high pitch, increased volume, repetition, simplified vocabulary and grammar, and exaggeration of words. Its use implies the older adult is dependent and incompetent.
endocrine system
A system of glands that secrete chemicals (hormones) directly into the circulatory system to trigger a response in specific body cells.
epiglottis
The cartilage shaped like a leaf that is attached along the interior anterior border of the thyroid cartilage in a hingelike fashion.
erythrocytes
The red blood cells that contain hemoglobin, an iron-containing protein that chemically bonds with oxygen.

hypercarbia
An increase in carbon dioxide.

hypothalamus
Plays an important role in the control of thirst, hunger, and body temperature. Also serves as a link between the nervous and endocrine systems.
