Introduction to body systems and homeostasis
| Answer | Question |
|---|---|
| organ | group of tissues working together to perform a specific function. |
| feedback | Feedback describes the situation when information about the result of an event in the past will influence the same event in the future which assists in maintainning homeostasis. |
| differentiation | process by which cells acquire the structures and functions to preform in a specific manner. |
| organ system | this is formed when two or more organs work together in a coordinated way to carry out similar functions. |
| tissue | group of cells that work together to perform a similar function. |
| homeostasis | Multiple organ systems working together to perform all of life’s necessary functions while interacting to maintain a balanced internal environment. |
| skeletal | body system that includes the bones and the connective tissues providing the body with support and protection. |
| integrumentary | body system that includes the skin and the tissues found within it. |
| muscular | body system that works with skeletal system to allow for locamotion. It also helps substances move throughout the body. |
| circulatory | body system responsible for transporting nutrients and wastes throughout the body. |
| lymphatic | body system that collects excess fluid that leaks out of the blood capillaries into the area between the cells and returns it to the circulatory system. |
| respiratory | body system that brings oxygen into the body and removes carbon dioxide. |
| endocrine | body system that controls growth, development, and responds the the environment by releasing chemical signals (hormones) into the bloodstream. |
| nervous | body system that controls life processes through physically connected network of cells, tissues, and organs by sending electronic signals. |
| immune | body system that aids in fighting off infections and pathogens by releasing specialized cells that travel through the lymphatic and circulatory systems to reach the site of infection. |
| digestive | body system that breaks down food from larger complex molecules to smaller ones that can be used by the body and helps convert food energy into a usable form. |
| excretory | body system that eliminates nonsolid wastes via sweat, urine, and exhalation to help maintain homeostasis. |
