Tissues of the Body

Page 2: Tissues of the Body. Cells combine to form tissues, and tissues combine to form organs. There are four primary types of tissues –Epithelial tissue –Connective

•Cells combine to form tissues, and tissues combine to form organs.

•There are four primary types of tissues– Epithelial tissue– Connective tissue– Muscle 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

Page 5: Tissues of the Body. Cells combine to form tissues, and tissues combine to form organs. There are four primary types of tissues –Epithelial tissue –Connective

• Has five functions: Secretion Absorption Excretion ProtectionSensation

Glandular Epithelia

• Epithelial tissues illustrate a basic biological principle: that structure closely correlates with function

• Figure 4.4

Page 11: Tissues of the Body. Cells combine to form tissues, and tissues combine to form organs. There are four primary types of tissues –Epithelial tissue –Connective

• Binds the cells and organs of the body together – All connective tissues

consist of two basic components: cells and extracellular fibers

• Two types of connective tissue are: – Fibrous Connective

tissue.– Specialized Connective

Section 4-1Connective Tissue

Page 12: Tissues of the Body. Cells combine to form tissues, and tissues combine to form organs. There are four primary types of tissues –Epithelial tissue –Connective

• An important structural component of organs – Consists of two types:

•Dense connective tissue •Loose connective tissue

Connective Tissue

Page 13: Tissues of the Body. Cells combine to form tissues, and tissues combine to form organs. There are four primary types of tissues –Epithelial tissue –Connective

• Perform specific functions essential to homeostasis

• The body contains three types of specialized connective tissue:

•Cartilage•Bone•Blood

Specialized Connective Tissues

Page 14: Tissues of the Body. Cells combine to form tissues, and tissues combine to form organs. There are four primary types of tissues –Epithelial tissue –Connective

•Cartilage – Consists of specialized cells embedded in a matrix of extracellular fibers and other extracellular material

•Blood –Contains blood cells, platelets, plasma

Osseous Tissue• Bone

– Consists of bone cells (osteocytes) and a calcified cartilage matrix•Two types of bone tissue exist: spongy and compact

Page 16: Tissues of the Body. Cells combine to form tissues, and tissues combine to form organs. There are four primary types of tissues –Epithelial tissue –Connective

• 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 Tissue

• Contains 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 Systems

• Tissues 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.
