Heart
The four chambers of the heart...
What is the right atrium, left atrium, right ventricle, and left ventricle?
A type of blood cell that is made in the bone marrow and found in the blood.
What are red blood cells?
Any of the muscular-walled tubes forming part of the circulation system by which blood is conveyed from the heart to all parts of the body.
What is an artery?
The amount of air that remains in a person's lungs after fully exhaling.
What is residual volume?
The process in which moisture is carried through plants from roots to small pores, where vapor is released into the atmosphere.
What is transpiration?
When the heart contracts, it is specifically the maximum arterial pressure during contraction of the left ventricle of the heart (pumping).
What is systolic pressure?
A colorless cell that circulates in the blood and body fluids and is involved in counteracting foreign substances and disease.
What are white blood cells?
Any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.
What are veins?
The greatest volume of air that can be expelled from the lungs after taking the deepest possible breath.
What is vital capacity?
A type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
What is evaporation?
The pressure in the arteries when the heart rests between beats (filling).
What is diastolic pressure?
Often measured for diagnosis, since it is closely related to the force and rate of the heartbeat and the diameter and elasticity of the arterial walls.
What is blood pressure?
A nitrogenous compound containing a carbonyl group attached to two amine groups with osmotic diuretic activity.
What is a urea?
The maximum amount of air that can fill the lungs.
What is total lung capacity?
Water which collects as droplets on a cold surface when humid air is in contact with it.
What is condensation?
Any of the muscular-walled tubes forming part of the circulation system by which blood is conveyed from the heart to all parts of the body.
What is a pulmonary artery?
A red protein responsible for transporting oxygen in the blood of vertebrates.
What are hemoglobins?
A thin skeletal muscle that sits at the base of the chest and separates the abdomen from the chest.
What is a diaphragm?
The lung volume representing the normal volume of air displaced between normal inhalation and exhalation.
What is tidal volume?
A process by which a chemical is converted from a liquid solution into a solid crystalline state.
What is crystallization?
A vein carrying oxygenated blood from the lungs to the left atrium of the heart.
What are pulmonary veins?
A small colorless disk-shaped cell fragment without a nucleus, found in large numbers in blood and involved in clotting.
What are platelets?
A set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.
What is cellular respiration?
The supply of air to the lungs, especially by artificial means.
What is ventilation?
The action or process of precipitating a substance from a solution (Rain, snow, sleet, or hail that falls to the ground).
What is precipitation?
