A cancer originating in the cells of the bone marrow
Initiator
A carcinogen, an agent required to start the for,action of cancer
Mutation
A change in a cells genetic material. Once the genetic material has change is inherited by the offspring of the cell
Embolus
A clot that breaks loose and travels through the bloodstream. When it causes sudden closure of a blood vessel, this dangerous event is an embolism
Diabetes mellitus
A condition of abnormal use of glucose, usually caused by too little insulin or lack of response to insulin
Malignancy
A dangerous cancerous growth that sheds cells into body fluids and spreads to new locations to start new cancer colonies
Pacemaker
A device that delivers electrical impulses to the heart to regulate the heartbeat
Cancer
A disease In which abnormal cells multiply out if control, spread into surrounding tissues and other body parts, and disrupt normal functioning of one or more organs
Cardiovascular disease (CVD)
A general term for all diseases of the heart and blood vessels
Insulin
A hormone produced by the pancreas and released in response to high blood glucose following a meal. Insulin promotes the use and storage of glucose by the body's tissue
Diabetic coma
A loss of consciousness due to uncontrolled diabetes and resulting buildup of toxic ketones in the blood
Artificial heart
A pump designed to fit into the human chest cavity and perform the hearts function of pumping blood around the body
Electrocardiogram
A record of the electrical activity of the heart that, if abnormal, may indicate heart disease
Generic engineering
A science of manipulating the genes of living things to install some desirable trait not present in the original organism
Tumor
An abnormal mass of tissues that can live and reproduce itself, but performs no service to the body
Melanoma
An especially dangerous cancer of the pigmented cells of the skin, related to sun exposure in people with light-colored skin
Heart disease
Any disease of the heart muscle or other working parts of the heart
Lymphomas
Cancers that arise in organs of the immune system
Leukemia so
Cancers that arise in the blood cell making tissues
Sarcomas
Cancers that arise in the connective tissue cells, including bones, ligaments, and muscles
Carcinomoas
Cancers that arise in the skin, body chamber linings, or glands
Fibrillation
Extremely repaid contractions of the heart that la k the power needed to pump blood around the body
Risk factors
Factors linked with a disease by association but not yet proved to be causes
Valves
Flaps of tissue that open and close to allow the flow of blood in one direction only. The heart's valves are located at the entrances and exits of its chambers
Chambers
Rooms; in the heart, large, hollow areas that receive incoming blood from the lungs and tissues and ship it out again
Critical phase
In atherosclerosis, the stage when plaques cover more than half of the inner surfaces of the arteries
High-density lipoproteins
Lipoproteins that carry fat and cholesterol away from the tissues back to the lover for breakdown and removal from the body
Low density lipoproteins
Lipoproteins that carry fat and cholesterol from the liver, where they are made, to the tissues where they are used. LDLs also deposit cholesterol in arteries, forming plaques
Suntan lotion
Lotion that may or may not have any sunscreen protection
Plaques
Mounds of fat, mixed with minerals , that build up along artery walls in atherosclerosis
Angina
Pain in the heart region caused by lack of oxygen
Coronary artery bypass surgery
Surgery to provide and alternate route for blood to reach heart tissue, bypassing a block coronary artey
Lipoproteins
Protein and fat clusters that transport fats in the blood
Radiation therapy
The application of cell-destroying radiation to kill cancerous
Aneurysm
The ballooning out of an artery walk at a point where it has grown weak
Systolic pressure
The blood pressure during that part of the heartbeat when the hearts ventricles are contracted and the blood is being pushed out into the arteries
Diastolic pressure
The blood pressure during that part of the heartbeat when the hearts ventricles are relaxing
Lymph
The clear fluid that bathes each cell and transfers needed substances and wastes back and fourth between the blood and the cells. Lymph also plays a role in immunity
Cerebral thrombosis
The closing off of a vessel that feeds the brain by a stationary clot
Coronary thrombosis
The closing off of a vessel that feeds the heart muscle by stationary clot
Heart attack
The event in which vessels that feed the heart muscle become blocked, causing tissue death
Aorta
The largest artery in the body; it conducts freshly oxygenated blood from the heart to the tissues
Insulin shock
The result of too much insulin, which causes a dangerous drop in blood glucose. Also called hypoglycemia
Stroke
The shutting off of the blood flow to the brain by plaques, a clot, or hemorrhage
Capillaries
The smallest blood vessels, which connect the smallest arteries with the smallest veins. Nourishment and fluid normally trapped in thick-walled arteries and veins can easily pass through the delicate walls of the capillaries
Embolism
The sudden closure of a blood vessel by a traveling blood clot
Heart transplant
The surgical replacement of a diseases heart with a health one
Cardiovascular system
The system of structure that circulate blood and lymph throughout the body
Blood
The thick, red fluid that flows through the body's blood vessels and transports gases, nutrients, wastes, and other important substances around the body. Blood also plays roles in body temp. Regulation
Ventricles
The two lower chambers of the heart- the shipping areas that send blood on its way to the lungs or tissues
Atria
The two upper chambers of the heart - the receiving areas that pool incoming blood
Platelets
Tiny, disk-shaped bodies in the blood, important in blood clot formation
Metastasized
When peaking of cancer cells, a term that means the cancer cells have migrated from one part of the body to another, and started new growths just like the original tumor
Polyps
Tumors that grow on a stem, resembling mushrooms, polyps bleed easily and seome have the tendency to become malignant
Cruciferous vegetables
Vegetables of the cabbage family
Thrombus
A stationary clot. When it has grown enough to close off a blood vessel, this dangerous event is a thrombosis
Promotor
A substance that assists in the development of malignant tumors, but does not initiate them on its own.
Phytochemicals
Chemicals in plant - based foods that are not nutrients but that have effects on the body
Irradiation
Ionizing radiation applied to food to kill microorganisms and other pets
Benign
Noncancerous; not harmful; a description of a tumor that is not able to spread from one area to another
Chemotherapy
The administration of drugs that harm the cancer cells, but that do not harm the client, or at least do not harm the client as much as the disease does
Atherosclerosis
The most common form of CVD; a disease characterized by plaques along the inner walls of the arteries
