Knowledge
Students know:
- Three of the four types of membrane are composed of epithelium covering connective tissue. The fourth membrane type, synovial membranes, is composed solely of connective tissue.
- The four types of membrane are specialized according to structure, location, and function.
- The integumentary system is composed of the skin and its accessory structures.
- The layered structure of the epidermis provides a regenerative, protective barrier to the body's interior.
- Dermis is the deep inner layer of skin that gives strength and elasticity to skin and that contains the majority of strutures associated with the skin, such as hair follicles, sensory receptors, and glands.
- The skin is comprosed of various cell types that each have a unique function within the skin.
- Each of the accessory structures of the integumentary system has a specific structure and location within the skin.
- Each of the accessory structures of the integumentary system has a particular function within the structure of the skin.
- The integumentary system is responsible for specific functions, several of which are integral to maintaining homeostasis.
- The integumentary system is affected by an array of pathological conditions. The effect of such conditions determines how the body responds.
- The integumentary system is integral to maintaining homeostasis.
Skills
Students are able to:
- Obtain and communicate information to explain the structure and function of the types of membranes.
- Gather, read, and interpret scientific information about the integumentary system and its structure, including layers and accessory structures.
- Gather, read, and interpret scientific information about the integumentary system and its function, including layers and accessory structures.
- Communicate scientific information, in multiple formats (e.g., orally, graphically, textually) to explain the structure and function of the integumentary system, as a whole, and of its intrinsic parts.
- Use scientific literature to identify conditions and diseases that effect the integumentary system.
- Evaluate, based on evidence, how these conditions and diseases affect the body.
- Analyze data in order to make a valid and reliable scientific claim about how the body responds to the identified conditions and diseases in its attempt to maintain homeostasis.
Understanding
Students understand that:
- The integumentary system is a complex system comprised of organs that have a primary function to protect the body from homeostatic imbalances such as foreign invaders (viruses, bacteria, fungus, parasites) and the environment.
- The integumentary system is comprised of the skin as well as accessory structures that allow the skin to accomplish its various homeostatic functions.
- Cause and effect relationships can be suggested and predicted for compmlex systems by examining what is known about smaller scale mechanisms within the system.
- Changes in systems may have various causes that may not have equal effects.
- The body's response to the disease process is complex and involves numerous systems working synergetically to respond to homeostatic imbalances.
