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.
We refer to an integrated unit as an organ system. Groups of organ systems work together to make complete, functional organisms, like us! There are 11 major organ systems in the human body, which include the circulatory, respiratory, digestive, excretory, nervous and endocrine systems.
