What is the organization of the human body?
Humans and other complex organisms have specialized systems that maintain the internal environment, keeping it steady and able to provide for the needs of the cells. Different systems of the body carry out different functions.
Sep 27, 2022 · The biology of the human body incorporates the body’s structure, the study of which is called anatomy, and the body’s functioning, the study of which is called physiology. The organization of the human body can be seen as a hierarchy of increasing size and complexity, starting at the level of atoms and molecules and ending at the level of ...
The integumentary system functions to enclose internal body structures and is the site of many sensory receptors. Some organs of this system include skin, hair, and nails. The skeletal system supports the body and enables movement (with the help of the muscular system). Bones are the major organs of this system.
Jul 25, 2024 · The study of physiology primarily revolves around the body's tendency to maintain homeostasis, the ability to maintain the state of a stable internal environment and ensure survival. In this article, we will provide an overview of the physiology of different organ systems and lay the foundation for a deeper understanding of the human body. Contents
- The Chemical level. To study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms and molecules.
- Cells. A cell is the smallest independently functioning unit of a living organism. Even bacteria, which are extremely small, independently-living organisms, have a cellular structure.
- Tissues. In the body’s organizational hierarchy, tissues occupy a place between cells and organs. That is, a tissue is a group of cells with a similar shape and function.
- Organs. The organ level of organization in the body may be the most familiar to us from our everyday experiences. Many of the common ailments we hear about—an upset stomach, a broken bone, lung disease, skin cancer—are named for the organs they affect.
Life processes of the human body are maintained at several levels of structural organization. These include the chemical, cellular, tissue, organ, organ system, and the organism level. Higher levels of organization are built from lower levels.
Nov 3, 2023 · Functions of the skeletal system are mechanical support, movement, protection, blood cell production, calcium storage and endocrine regulation. Elements of the skeletal system are adjusted to the function of the body part they support.
