Biological organization spans several scales and are determined based different structures depending on what the system is. [1] Examples of biological systems at the macro scale are populations of organisms. On the organ and tissue scale in mammals and other animals, examples include the circulatory system, the respiratory system, and the ...
The principal level of focus of physiology is at the level of organs and systems within systems. The endocrine and nervous systems play major roles in the reception and transmission of signals that integrate function in animals. Homeostasis is a major aspect with regard to such interactions within plants as well as animals. The biological basis ...
In physiology, a function is an activity or process carried out by a system in an organism, such as sensation or locomotion in an animal. [1] This concept of function as opposed to form (respectively Aristotle's ergon and morphê [2]) was central in biological explanations in classical antiquity.
Tissues of different types combine to form an organ which has a specific function. The intestinal wall for example is formed by epithelial tissue and smooth muscle tissue. [2] Two or more organs working together in the execution of a specific body function form an organ system, also called a biological system or body system.
Multiple macromolecules form a cell, like a club cell. A group of cells functioning together as a tissue, for example, Epithelial tissue. Different tissues make up an organ, like a lung. Organs work together to form an organ system, such as the Respiratory System. All of the organ systems make a living organism, like a lion.
Systems neuroscience – studies the function of neural circuits and systems. Theoretical Biology – the mathematical modeling of biological phenomena. Systems biology – computational modeling of biological systems. Zoology – study of animals, including classification, physiology, development, and behavior. Subbranches include:
Page of one of the first works of Biomechanics (De Motu Animalium of Giovanni Alfonso Borelli) in the 17th centuryBiomechanics is the study of the structure, function and motion of the mechanical aspects of biological systems, at any level from whole organisms to organs, cells and cell organelles, [1] using the methods of mechanics. [2]
Complex systems biology is a field of science that studies the emergence of complexity in functional organisms from the viewpoint of dynamic systems theory. [20] The latter is also often called systems biology and aims to understand the most fundamental aspects of life.
