Terms in this set (44)
soft fatty substance in the cavities of bones, in which blood cells are produced
an organ of soft nervous tissue contained in the skull (cranium) of vertebrates
the most basic unit of life that may or may not contain a nucleus (eukaryotic or prokaryotic)
Permits blood to travel around the body to take deoxygenated blood from the body and transport oxygenated blood to the body; also transports nutrients and wastes within the body
the skull, especially the part enclosing the brain
A thick layer of living tissue that forms the true skin
a dome-shaped, muscular partition separating the thorax from the abdomen in mammals. It plays a major role in breathing, as its contraction increases the volume of the thorax and so inflates the lungs.
The organs and glands in the body that are responsible for converting particles into simpler micromolecules out of water, salts, and nutrients that can be absorbed into the body as energy
the outer layer of cells covering an organism
Is a passive system that removes excess waste such as body fluids or solid wastes
the bone of the thigh or upper hind
the small sac-shaped organ beneath the liver where bile is stored after secretion by the liver and before release into the intestine
an organ in the human or animal body that secretes particular chemical substances for use in the body or for discharge into the surroundings.
It removes infectious diseases and other pathogens to protect the human body; stores white blood cells
a hollow muscular organ that pumps the blood through the circulatory system by rhythmic contraction and dilation. In vertebrates there may be up to four chambers (as in humans), with two atria and two ventricles.
is used to both describe the survival of organisms in an ecosystem and to describe the successful survival of cells inside of an organism.
The chemical substance produced in the body that controls and regulates the activity of certain cells or organs
each of a pair of organs in the abdominal area in mammals, reptiles, birds and other organisms made to filter and process the blood and regulates the passing of excess water and other liquified wastes through to the excretory system
the organ system that protects the body from various kinds of damage, such as loss of water or abrasion from outside (first line of defense)
the cecum, colon, and rectum collectively located in the stomach; the final section in the digestive system, the "big bowel"
each of the pair of organs situated within the rib cage which can helps us breath.
a large lobed glandular organ in the abdomen of vertebrates, involved in many metabolic processes, acts as a filter
each of a number of small swellings in the lymphatic system where lymph is filtered and lymphocytes are formed.
is part of the circulatory system and a vital part of the immune system, comprising a network of lymphatic vessels that carry a clear fluid called lymph straight to the heart
a band or bundle of fibrous tissue in a human or animal body that has the ability to contract
an organ system consisting of skeletal, smooth cardiac muscles that work with the skeletal system and the nervous system to create movement and help circulate blood throughout the body; used to cause the voluntary and involuntary movement internally and externally in an organism
a whitish fiber or bundle of fibers that transmits impulses of sensation to the brain or spinal cord, and impulses from these to the muscles and organs.
the organ system that coordinates the body's response to changes in its internal and external environment
A group of tissues in a living organism that have been adapted to perform a specific function.
Is a group of organs that work together to perform one or more functions.
Is a bone-forming cell that has become entrapped within the bone matrix (the hard part of the bone). It lies within a lacuna, a small pit, and communicates with its surroundings through tiny channels called canaliculi.
Is a long, flat gland that lies in the abdomen behind the stomach that helps in digestion by producing enzymes and helps with the regulation of glucose by producing insulin.
Produces, matures, nourishes, and stores gametes and controls the process of reproduction for the organism
to provide the body with a fresh supply of oxygen for cellular respiration
the system that provide structure and support to the body and cooperates with the muscular and nervous systems to cause the organism to create movement
The part of the intestine that lies between the stomach and colon, consists of duodenum, jejunum, and ileum, secretes digestive enzymes, and is the chief site of the absorption of digested nutrients—called also small bowel
the cylindrical bundle of nerve fibers and associated tissue that is enclosed in the spine and connects nearly all parts of the body to the brain, with which it forms the central nervous system.
An abdominal organ involved in the production and removal of blood cells and storage of white blood cells and platelets in most vertebrates and forming part of the immune system.
the internal organ in which the major part of the digestion of food occurs, being (in humans and many mammals) a pear-shaped enlargement of the alimentary canal linking the esophagus to the small intestine.
any of the distinct types of material of which animals or plants are made, consisting/made of specialized cells and their products
The organs of the urinary tract comprising the kidneys, ureters, urinary bladder, and urethra
White Blood Cells
Any of the blood cells that lack hemoglobin, colourless and with nucleus. Its primary role involves the body's immune system, protecting the body against invading microorganisms and foreign particles.
the system that controls growth, development, metabolism and reproduction through the production and secretion of hormones
making up the skeleton in humans and other vertebrates.
