Study Notes
The Hierarchy of Structure in Animals
- Multicellular organisms, like animals, are composed of many specialized cells.
- Each cell has a specific function, for example, stinging cells in jellyfish capture prey, light-emitting cells in fireflies attract mates.
- Single-celled organisms such as bacteria and blue-green algae are independent; they don't rely on other cells for survival.
- Specialized animal cells (e.g., bone cells, hair cells, stomach cells) cannot survive independently; they rely on neighboring cells for function.
- Animal bodies are complex collections of cells working together to perform essential functions like survival and reproduction.
- Complexity varies; sponges have simple structures, while vertebrates (such as birds) have complex bodies.
Animal Body - Levels of Organization
- Animal bodies have different levels of organization, arranged from least complex to most complex, allowing them to function.
- Animals are made of cells organized in a way that allows them to perform life-sustaining functions.
- Levels of organization include cells, tissues, organs, and organ systems.
- Individual cells work together to form tissues, which are grouped by similar cell types that perform common functions.
- Tissues combine to form organs, structures composed of multiple tissues.
- Organs and other body parts, functioning together, form organ systems.
- Organ systems perform complex life functions.
Organ Systems
- All animals perform the same fundamental functions (obtaining oxygen and nutrients, eliminating wastes, sensing the environment, growing, and reproducing).
- Organ systems are groups of organs and structures that work together to perform one or more important functions for an animal.
- Examples of organ systems include the musculoskeletal system (movement and support), reproductive system, respiratory system (oxygen and carbon dioxide exchange), circulatory system, urinary system, nervous system, and digestive system.
Tissues
- Animals have four main types of tissues: epithelial tissue (protection and lining), connective tissue (support and structure), muscle tissue (movement), and nerve tissue (communication and control).
- Each tissue type is composed of specialized cells.
- These tissues work together in organs to accomplish varied functions.
