Atrophy

Capillary
A tiny blood vessel, through which food and oxygen and other substances pass to the cells
Cell
The basic unit of body structure
Chronic
A condition lasting a long time
Collaterol
Additional growth, like a small side branch of blood vessel or nerve
Compensation
When the organ or system cannot adapt, then it must compensate. To compensate is to alter the function in such a way that the body can still carry on. The compensation may not be helpful, but it does allow the body to carry on
Connective
A tissue which holds organs in place, holds the body together, forms the framework of the body, sheaths the muscles, and connects muscles to bones and bones to joints. Bone is a dense form of connective tissue. (It is also the most abundant tissue in the body
Digestion
The process of physically and chemically breaking down food so that it can be absorbed for use by the cells of the body
Enzyme
A substance that speeds up a chemical change
Epithelial
Appears in sheet-like arrangements of cells that form the outer layer of the skin, cover the surfaces of organs, line the walls of cavities, and form tubes, ducts, and portions of certain glands. The functions of epithelial tissues include protection, absorption, secretion, and excretion
Hemoglobin
The substance in red blood cells gives the blood its colour and is needed by cells to carry oxygen
Hormone
A chemical substance, secreted by glands, that controls or regulates many body functions
Hypertrophy
Increase in size of an organ or tissue, produced by enlargement of the existing cells
Hypoxia
Lack of oxygen to the tissue
Infarction
The obstruction of the blood supply to an organ or region of tissue causing local death of the tissue
Ischemia
Reduced blood supply to an area resulting in reduced oxygen to the cells and tissues in that area
Membrane
A thin layer of tissue that covers a surface, lines a cavity, or divides a space or a cavity
Metabolism
The use of food for heat and energy by the cell
Muscular
The muscular system is involved in movement of the body and its parts. There are three types of muscles. Some are in control of (voluntary),and others move automatically, without our knowledge (involuntary and cardiac)
Necrosis
Death of cells or tissues
Organ
A group of tissues which perform the same function
Peristalsis
Involuntary muscle contractions in the digestive system that move food through the digestive tract
Respiration
The process of supplying cells with oxygen and removing carbon dioxide from them, by breathing air in and out of the lung
Sign
Visible manifestation that may indicate an illness
Symptom
A sensation, pain, or lack of function that may indicate an illness
System
Organs that work together to perform special function
Systemic
Involving or affecting the body as a whole
Tissue
A collection of cells which perform the same function
Vein
Blood vessels that carry blood from parts of the body back to the heart
