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.
Systems of the human body. Skin and nails are part of the integumentary system that helps protect the body. Earthworms have organ systems that help them move, breathe, and digest food. The endocrine system is responsible for producing and regulating hormones in the bloodstream to control bodily functions.The urinary system is a type of organ system that allows the body to rid itself of waste. The respiratory system is made up of the mouth, throat, nose, sinuses, bronchial tubes, and lungs.The torso houses many of the human body's organ systems.n biology, an organ system is a group of organs that work together for one purpose. Their interdependency on one another is critical for normal life functions, and if any one were to fail, it would subject the others to stress, possibly causing the whole group to shut down, with fatal results.
