Microscopic view of a histologic specimen of human lung tissue stained with hematoxylin and eosin. Haematoxylin and eosin staining is frequently used in histology to examine thin tissue sections. [10] Haematoxylin stains cell nuclei blue, while eosin stains cytoplasm, connective tissue and other extracellular substances pink or red. [10]
The human body is the entire structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organs and then organ systems . The external human body consists of a head , hair , neck , torso (which includes the thorax and abdomen ), genitals , arms , hands , legs , and feet .
The human body consists of biological systems, that consist of organs, that consist of tissues, that consist of cells and connective tissue. The history of anatomy has been characterized, over a long period of time, by a continually developing understanding of the functions of organs and structures of the body.
Tissue clearing is usually useful only combined with one or more fluorescent labeling techniques such as immunolabeling and subsequently imaged, most often by optical sectioning microscopy techniques. [1] [5] [6] Tissue clearing has been applied to many areas in biological research. [7]
In biology, tissue is an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. [1] [2] Tissues occupy a biological organizational level between cells and a complete organ.
The recipes emerged from Claude L. Pierre Masson's (1880–1959) original formulation have different specific applications, but all are suited for distinguishing cells from surrounding connective tissue. Most recipes produce red keratin and muscle fibers, blue or green collagen and bone, light red or pink cytoplasm, and dark brown to black cell ...
The H&E staining procedure is the principal stain in histology [3] [7] [2] [5] in part because it can be done quickly, [7] is not expensive, and stains tissues in such a way that a considerable amount of microscopic anatomy [9] [10] is revealed, [7] [5] [4] and can be used to diagnose a wide range of histopathologic conditions.

ISBT 128 is a global standard for the identification, labelling, and information transfer of medical products of human origin (MPHO) within and between facilities, across international borders and disparate health care systems. MPHO includes blood, cells, tissues, human milk, and organ products, among others.
