How do tissues differ from organs

Tissue: A tissue is composed of similar types of cells. Organ: An organ is composed of several types of tissues. Tissue: Tissue is involved in performing a single function in the body. Organ: An organ is capable of performing several functions in the body. Tissue: Tissues are evenly distributed structures. Tissue: Tissue is the major structural component of an organ. Organ: Organs are the structural components of the organ system. Tissue: Epithelial tissue, connective tissue, muscular tissue, nerve tissue, and ground tissue are the examples of tissues.

Organ: Heart, stomach, intestine, lungs, and kidney are the examples of organs. Tissue: Tissues can be repaired by regeneration and fibrosis. Organ: The repair in tissues causes the repair in organs. Tissue: A tissue may have a unique function in the body, and it forms organs.

Organ: An organ has vital physiological functions in the body. Organ: Organs form organ systems in the body. Tissue and organ are two higher organizational levels in the body of multicellular organisms. Learn more about our commitment to Global Medical Knowledge.

The Human Body. Test your knowledge. Health care costs in the United States are far higher than in many other developed nations. Several factors are responsible Which of the following is NOT one of the largest contributors to the high cost of health care in the United States?

More Content. In addition, within the gut there are stem cells that guarantee a steady supply of new cells that contribute to the multiple cell types necessary for this complex structure to function properly Figure 2. The extracellular matrix ECM is also critical to tissue structure, because it provides attachment sites for cells and relays information about the spatial position of a cell.

The ECM consists of a mixture of proteins and polysaccharides produced by the endoplasmic reticula and Golgi apparatuses of nearby cells. Once synthesized, these molecules move to the appropriate side of the cell — such as the basal or apical face — where they are secreted. Final organization of the ECM then takes place outside the cell.

To understand how the ECM works, consider the two very different sides of the gut endothelium. One side of this tissue faces the lumen, where it comes in contact with digested food. The other side attaches to a specialized ECM support structure called the basal lamina. The basal lamina is composed of collagen and laminin proteins, as well as various other macromolecules. On this side of the endothelium, adhesive junctions attach cells to the ECM. Transmembrane integrin proteins in the junctions bind components of the ECM and recruit signaling proteins to their cytoplasmic sides.

From there, the signals travel to the nucleus of each cell. This page appears in the following eBook. Aa Aa Aa. Cell Differentiation and Tissue. The gut contains a mixture of differentiated cells and stem cells. Figure Detail. Tissues are communities of cells that have functions beyond what any single cell type could accomplish. Healthy tissues require the proper mix of cells, and the cells within them must be oriented correctly and dividing at an appropriate rate.

In order to coordinate their function, organization, and rates of death and division, the cells in a tissue are constantly processing and responding to signals from one another and from the ECM around them.

Or Browse Visually. Student Voices. Creature Cast. Simply Science. The next level is the organ system level. Many organs working together to accomplish a common purpose create an organ system. For example, the heart and the blood vessels of the cardiovascular system circulate blood and transport oxygen and nutrients to all the body cells. Levels of Organization : Molecules form cells.

Cells form tissues, and tissues form organs. Organs that fulfill related functions are called organ systems. An organism is made up of interconnected organ systems.
