The transport system of the body responsible for carrying oxygen and nutrients to the body and carrying away carbon dioxide and other wastes; composed of the heart, blood vessels, and blood.
The body system that consists of the heart, blood vessels, and blood; also called the circulatory system
open circulatory system
A circulatory system where blood flows out of the blood vessels and bathes the organs in the body cavity; Mollusks and arthropods have this type of circulatory system
blood is NOT in a system of vessels
closed circulatory system
A circulatory system in which blood moves only within a connected network of tubes called blood vessels.
A hollow, muscular organ that pumps blood throughout the body.
The tubes blood travels through
Arteries, Arterioles, Capillaries, Venules, Veins
A circulating connective tissue made of plasma, cells, and platelets
Carries oxygen, nutrients, carbon dioxide and other wastes to and from the body's cells
Upper heart chamber that receives blood returning to the heart from other parts of the body
A lower chamber of the heart that pumps blood out to the lungs and body
larger, muscular chambers of the heart
A flap of tissue in the heart or a vein that prevents blood from flowing backward.
Carries oxygenated blood from the heart to the body
The largest artery in the body
vena cava (superior and inferior)
Brings blood back to the heart from the body
Largest body vein
A blood vessel that carries blood away from the heart. Arteries have muscular walls to regulate blood flow and are typically high-pressure vessles.
The smallest branches of arteries that connect to a network of capillaries.
Any of the smallest blood vessels (one cell thick) connecting arterioles with venules and forming networks throughout the body.
The site of gas and nutrient exchange between the blood and body cells
The very small veins that connect capillaries to the larger veins
Blood vessels that carry blood back to the heart, less pressure, have valves to prevent blood from flowing backwards
Beat of the heart as felt through the walls of the arteries.
The alternating expansion and relaxation of an artery wall as blood is forced through it each time the heart beats
A measure of the amount of force that the blood places on the walls of blood vessels, particularly large arteries, as it is pumped through the body, usually measured by means of a sphygmomanometer and expressed in millimeters of mercury.
The flow of blood from the heart, through the lungs, and back to the heart. Deoxygenated blood becomes oxygenated in the lungs.
The flow of blood from the heart, through the body (not including the lungs), and back to the heart.
Liquid portion of blood made up of water, dissolved salts, proteins, and other substances
A sticky, yellow fluid that carries the blood cells and nutrients and transports cellular waste material to the organs of excretion.
red blood cell
Blood cells containing hemoglobin that carry oxygen and carbon dioxide through the bloodstream
white blood cell
Blood cells that perform the function of destroying disease-causing microorganisms. A blood cell that fights disease.
Cell fragments that play an important part in forming blood clots
Iron-containing protein in red blood cells that binds oxygen and transports it to the body
Process of transferring blood from one body to another.
A marker protein found on red blood cells...helps identify blood type
A protein produced by some white blood cells to attack specific foreign materials like foreign blood antigens.
