Indicating the arterial pressure during the interval between heartbeats.
Process that allows molecules to move across a membrane in an effort to equal concentration

The act or process of discharging waste matter from the blood, tissues, or organs.
The act of exhaling or forcing air from the lungs. Also referred to as expiration
The organ of the body that by its rhythmical contractions circulates the blood
The number of times the heart beats in a minute
The tendency of a system, esp. the physiological system of higher animals, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus tending to disturb its normal condition or function.
A chemical substance formed in some organ of the body, secreted directly into the blood, and carried to another organ or tissue, where it produces a specific effect.
The act of bringing air into the lungs through the contraction of the diaphragm. Also referred to as inspiration.
Either of a pair of organs in the back part of the abdominal cavity that form and excrete urine, regulate fluid and electrolyte balance, and act as endocrine glands
The upper portion of the trachea
Either of two spongy, saclike respiratory organs in most vertebrates, occupying the chest cavity together with the heart or functioning to remove carbon dioxide from the blood and provide it with oxygen
The filtering and excretory unit of the kidney, consisting of the glomerulus and tubules.
One or more bundles of fibers forming part of a system that conveys impulses of sensation, motion, etc., between the brain or spinal cord and other parts of the body.
A nerve cell
Part of the autonomic system that slows the body from the flight-or-fight mode, lowering heart rate and blood pressure.
The cavity that connects the mouth and nasal cavity to the throat, a passage common to the digestive and respiratory tracts.
The science that deals with the function of a plant or animal's body and its organs, systems, tissues, and cells
A small endocrine gland located in the lower part of the brain. Among other functions, it secretes hormones into the bloodstream that influence growth of the body, stimulate the thyroid gland, the sex organs, and the mammary gland to initiate the secretion of milk after the birth of the young.
The circulation of blood from the heart to the lungs for oxygenation and back to the heart.
The expansion and contraction of an artery associated with each heartbeat

Of or pertaining to the kidneys or the surrounding regions
1) A chemical process that takes place in living cells whereby food is "burned" to release energy and waste products, mainly carbon dioxide and water. Living things use energy produced through respiration to drive vital life processes such as growth and reproduction. 2) In animals, the act of breathing; the drawing of air into the lungs and its exhalation.
The number of times an organism breathes in one minute
A way of limiting, controlling, or stopping an animal

Operates the voluntary motor activity of the body
An instrument, often attached to an inflatable air-bladder cuff and used with a stethoscope, for measuring blood pressure in an artery
An instrument used in listening to convey sounds in the chest or other parts of the body to the ear of the examiner.
The circulatory system excluding the pulmonary circulation
The part of the autonomic system that stimulates organs for flight or fight.
Indicating the maximum arterial pressure occurring during contraction of the left ventricle of the heart.
A ductless gland situated in the neck of humans and animals, which secretes thyroxin, a hormone that controls the rate of metabolism and has a profound influence on growth and production.
To ascertain the quantity of a given constituent by adding a liquid reagent of known strength and measuring the volume necessary to convert the constituent to another form.
The windpipe; in mammals, it extends from the throat to the bronchi.
The bodily system consisting of the organs that produce, collect, and eliminate urine and including the kidneys, ureters, urinary bladder, and urethra.
The large veins that carry blood into the right atrium of the heart.
One of the two pumping chambers of the heart
