Tissue Ownership

September, 2013 Tissue Ownership “I think people are morally obligated to allow their bits and pieces to be used to advance knowledge to help others” (Korn). Different people have opposing opinions on the topic of whether or not patients or doctors own the body tissues after it’s been removed from the patient. Ownership is the act, state, or right of possessing something. Tissue ownership is different from ownership because once it leaves your body, you no longer own it. Contributing your tissues to the...

Complex Permanent Tissue

Complex permanent tissue A complex permanent tissue may be classified as a group of more than one type of tissue having a common origin and working together as a unit to perform a function. These tissues are concerned with transportation of water, mineral, nutrients and organic substances. The important complex tissues in vascular plants are xylem, phloem. Complex permanent tissue is heterogeneous tissue which is formed of two or more than two types of mature cells of common origin which coordinate...

A Level Tissues

Epithelial tissue Covers the body surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection, secretion, absorption, and filtration. The skin is an organ made up of epithelial tissue which protects the body from dirt, dust, bacteria and other microbes that may be harmful. Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialised to form the...

Classification of Tissue

Classification of Tissues Introduction Cells are the smallest units of life. In complex organisms, cells group together with one another based on similar structure and function to form tissues .Tissues provide the numerous functions of organs necessary to maintain biological life. This lab exercise seeks to introduce the various tissues found in the human body and to familiarize you with their composition and function. The study of tissues is called histology , and is important to the understanding...

connective tissues

Connective Tissue As the name implies, connective tissue serves a "connecting" function. It supports and binds other tissues. Unlike epithelial tissue, connective tissue typically has cells scattered throughout an extracellular matrix. Loose Connective Tissue In vertebrates, the most common type of connective tissue is loose connective tissue. It holds organs in place and attaches epithelial tissue to other underlying tissues. Loose connective tissue is named based on the "weave" and type...

Compare and Contrast Xylem Tissue and Phloem Tissue, Including Their Respective Structures and Functions.

contrast xylem tissue and phloem tissue, including their respective structures and functions. The stems and roots of plants contain two separate transport systems; xylem vessels and phloem tubes, of which neither transport oxygen as it is transported to cells by diffusion. The network of xylem vessels transports water and mineral ions from the roots to all other parts of the plant whereas phloem tubes transport food made in the leaves to all other parts of the plant. In the stems the tissue is collectively...
