There are three types of filaments in the cytoplasm of most vertebrate cells: microfilaments, microtubules, and intermediate filaments. All of these filament systems share a critical feature: They are composed of proteins that have the unique property of being able to self-assemble into a filamentous network.
A biological unit of the body or of an organism. Examples of systems in human body: â¢ Circulatory system â¢ Digestive system â¢ Endocrine system â¢ Integumentary system â¢ Lymphatic system â¢ Muscular system â¢ Nervous system â¢ Reproductive system â¢ Respiratory system â¢ Skeletal system â¢ Urinary system.
Organ Systems. The human body is made up of several organ systems that work together as one unit. Organ systems fit between the hierarchical levels of organs and the organism. Ten major organ systems of the body are listed below along with several organs that are associated with each system. It is important to keep in mind that these organ systems don't just exist as individual units. The final product of these cooperating systems is one unit called the body.
