All living things, including animals and plants, are made up of chemically processing organisms that regenerate and sustain their own cells.
Among the many differences between animals and plants, the most notable is that animals have sensory organs, the ability to move on their own, and a physiological need for oxygen and organic nutrients. Plants can only exist on carbon dioxide and inorganic stuff as sustenance, and they have no ability to move or use any unique senses.
Digestion, metabolism, and equilibrium are all critical operations in the human body if it is to be healthy and live long.
Digestion is the process by which food is broken down into its most basic components on a physical and chemical level.
Foods are metabolized for development, maintenance, and repair in the body through the metabolism process. Self-regulation of the body’s internal environment is known as homeostasis. While the external world is always changing, the organism is able to maintain a constant state of balance because to this mechanism.
It is possible to divide the human body into many organizational levels such as chemo-organelle-cellular-tissue-organ-system-and-organ-system-levels.
Chemical level understanding
The chemical level is where the body’s structure begins to take shape. More than a hundred different chemical building units are known as atoms (tiny spheres of matter so minuscule that they are not visible). Atoms make up everything in the cosmos, including our bodies.
The organelle level
A cell’s organelle level refers to the little chemical structures that make up the cell’s organelles and have a specific purpose within the cell. It is found inside a cell and is essential for the cell’s survival.
The cellular level
Level cells are the smallest and most numerous structural unit that has and demonstrates the fundamental properties of living stuff. Despite the fact that all cells share a few characteristics, they become specialized when it comes to carrying out certain tasks.
The tissue level
Tissue level: Tissues are made up of a large number of comparable cells that originate from the same region of the embryo and all have a specific purpose to execute. The body’s “fabric” is made up of tissues. Examples include those that are epithelial or muscular.
The organ level
Tissue is simple in comparison to organs, which are extremely sophisticated organ systems. An organ is a structure made up of various tissues organised in such a way that they can work together to accomplish a certain job. Because every organ is different in size, shape, color, and appearance, it deserves its own section of the body. Some of the organs in the human body include the heart, lungs, spleen, and liver.
The system level
Organs are much more complicated than tissues. According to the definition of the term “organ,” it is any structure made up of various tissues grouped in such a way that they work together to accomplish a certain task. Each organ is distinct in terms of size, form, color, and location inside the body. A few examples of human body organs are the heart, lungs, liver, and spleen, among others.
