Document Summary
Physiology: the study of the functions of organisms. Pathophysiology: what happens when normal body function is disrupted. Organ system: a collection of anatomical structures that work together to carry out a specific function. Neurons (all specialized to transmit information in the form of electrical signals from one body location to another) Erythrocytes; carry oxygen in bloodstream, made by bone marrow. Erythropoietin; hormone that regulates synthesis of erythrocytes in blood. Neurons, muscle cells, epithelial cells, connective tissue cells. Muscle fibres: specialized to contract (found in skeletal, cardiac and smooth muscle) Epithelia: continuous, sheetlike layer of cells in combination with a thin underlying layer of noncellular material (basement membrane) (one layer thick; simple, several layers thick; stratified, short and flat; squamous, regular square-shaped; cuboidal, tall and long; columnar) Lumen: interior cavity of a hollow organ or vessel. Gland: organs specialized in the synthesis and secretion of a product (exo and endocrine)
