The Tissue Level Of Organization Tissues and homeostasis The four basic types of tissues in the human body contribute to homeostasis by providing diverse functions including protection, support, communication among cells, and resistance . A cell is a complex collection of compartments, each of which carries out a host of biochemical reactions that make life possible. However, a cell seldom functions as an isolated unit in the body. Instead, cells usually work together in groups called tissues. A tissue is a group of cells that usually have a common origin in an embryo and function together to carry out specialized activities. The structure and properties of a specific tissue are influenced by factors such as the nature of the extracellular material that surrounds the tissue cells and the connections between the cells that compose the tissue. Tissues may be hard, semisolid, or even liquid in their consistency, a range exemplified by bone, fat, and blood. In addition, tissues vary tremen

The Cellular Level  of Organization Cells and homeostasis Cells carry out a multitude of functions that help each system contribute to the homeostasis of the entire body. At the same time, all cells share key structures and functions that support  their intense activity. The human body these are combined into about 200 different types of words called cells—living structural and functional units enclosed by a membrane. All cells arise from existing cells by the process of cell division, in which one cell divides into two identical cells. Different types of cells fulfill unique roles that support homeostasis and contribute to the many functional capabilities of the human organism. Cell biology or cytology is the study of cellular structure and function. As you study the various parts of a cell and their relationships to one another, you will learn that cell structure and function are intimately related. In this Blog you will learn that cells carry out a dazzling array of chemical reactio

PARTS OF HUMAN BODY Upper main part of the body called HEAD. The head contains brain.
