1.An individual form of life, such as a bacterium, protist, fungus, plant, or animal, composed of a single cell or a complex of cells in which organelles or organs work together to carry out the various processes of life. 2.A system regarded as analogous in its structure or functions ...
they form an organ. Although most of your body’s organs contain all four types of tissue. Organs perform specific tasks necessary for your body to function. The heart, for example, pumps oxygenated blood throughout your body. Your lungs bring oxygen into your body and expel carbon dioxide. ...
After the death of an organism, the soft tissue is ordinarily consumed by scavengers and bacteria.(有机体死亡后,其软组织通常被清道夫和细菌所吞噬。) Thus aging and death should not be seen as inevitable, particularly as the organism possesses many mechanisms for repair.(因此,衰老和死亡不应被视...
organism: An individual form of life, such as a bacterium, protist, fungus, plant, or animal, composed of a single cell or a complex of cells in which organelles or organs work together to carry out the various processes of life.

A cell has sub-systems, namely, the organelles which perform partial processes. Thus a mitochondrion can be seen as a sub-system that integrates the molecular devices for processing energy. Looking at the next higher level beyond the cell, there is the tissue in which the cells are organized...

In many cases, this structure is the cell or the nucleus. To evaluate the probability of producing a cancer in an organ or tissue, the most appropriate measure of physical exposure is radiation dose. Estimation of population risks requires data on the distribution of exposures across that ...
“switch” in an almost discontinuous manner between cell fates. Depending on the particular tissue, the terminology can overlap; that is, the mutual exclusiveness is relative. For instance, in the adult a liver cell can switch between a differentiated state and a proliferative state. In the ...
Pathway Analysis is statistically linking observations on the molecular level to biological processes or pathways on the systems(i.e., organism, organ, tissue, cell) level. Traditionally, pathway analysis methods regard pathways as collections of single genes and treat all genes in a pathway as equ...
