- Cells
- Tissues(epitheilia, connective, nervous, and muscle)
- Organs
- Organ system
-
What does the epithilial tissue do?
supports the body and connects its parts
-
What does the conective tissue do?
includes glands and tissues that cover interior and exterior body surfaces
-
What does teh nervous tissue do?
along with bones, enables the body to move
-
What does the muscle tissue do?
transmits nerve impulses through the body
-
Circulatory system(4 things)
brings oxygen, nutrients, and hormones to cells; fights infection; removes cell wastes; helps to regulate temperature
-
Digestive system(3 things)
converts food into simpler molecuels that can be used by the cells of the body; absorbs food; eliminates waste
-
Endocrine system(2 things)
controls growth, development and etabolism; maintains homeostasis
-
Excretory system(1 thing)
eliminates waste products form the body in ways that maintain homeostasis
-
Integumentary system(3 things)
serves as a barrier gainst infection and injury; helps to reuglate temperature; provides protection agains ultraviolet radiation from the sun
-

works with the skeletal system to produce voluntary movement; helps to circulate blood and move food throught he digestive system
-
Nervous system(1 thing)
recognizes and coordinates the body's response to changes in its internal and external environments
-
Reproductive system(2 things)
Produces reporductive cells; in females, nurtures and protects developing embryo
-
