Tissues of the Body
Cells combine to form tissues, and tissues combine to form organs.There are four primary types of tissuesEpithelial tissueConnective tissueMuscle tissue Nervous tissue
Found in the outer cover of body and in the inner cavities. Has Two Types: Membranous epithelia: form the coverings or linings of organs.Glandular epithelia:form exocrine and endocrine glands.Epithelial Tissue
Has five functions: Secretion Absorption Excretion ProtectionSensation
Epithelial tissues illustrate a basic biological principle: that structure closely correlates with function
Binds the cells and organs of the body together All connective tissues consist of two basic components: cells and extracellular fibersTwo types of connective tissue are: Fibrous Connective tissue.Specialized Connective tissueSection 4-1Connective Tissue
An important structural component of organs Consists of two types: Dense connective tissue Loose connective tissue
Perform specific functions essential to homeostasis The body contains three types of specialized connective tissue:CartilageBoneBloodSpecialized Connective Tissues
Cartilage Consists of specialized cells embedded in a matrix of extracellular fibers and other extracellular materialBlood Contains blood cells, platelets, plasma
Osseous TissueBone Consists of bone cells (osteocytes) and a calcified cartilage matrixTwo types of bone tissue exist: spongy and compact
Consists of specialized cells that contract when stimulated The body has three types of muscle tissue:Skeletal (voluntary , striated)Cardiac (involuntary , striated)Smooth (involuntary . non-striated)Muscular Tissue
Nervous TissueContains specialized cells that conduct impulses Conducting cells, called neurons, transmit impulses from one region of the body to another. Nonconducting cells, neuroglia, are a type of nervous system connective tissue.
Organ SystemsTissues combine to form organs.Organs are discrete structures that have evolved to perform specific functions Most organs do not function alone, they are part of a group of cooperative organs, called an organ system.
