Facilitated Diffusion |
Uses membrane proteins that function as carriers to move molecules across the cell membrane |
|
Osmosis |
A special case of diffusion in which water moves from an area of greater water concentration across a selectively permeable membrane to an area of lower water concentration |
|
Active Transport |
Uses ATP to move molecules from areas of low concentration to areas of high concentration through carrier molecules in cell membranes. |
|
What are the four major types of tissue? |
Epithelial, Connective, Muscular, and Nervous Tissues |
|
Epithelial Tissue |
Widespread throughout the body; it covers organs and lines body cavities and hollow organs |
|
Function in protection, secretion, absorption, and excretion |
Epithelial Tissue |
|
Connective Tissue |
Bind, support, protect, serve as frameworks, fill spaces, store fat, produce blood cells, protect against infection, and help repair tissue damage |
|
Loose Connective Tissues |
Areolar, Adipose, and Reticular Connective Tissue |
|
3 Types of Muscle Tissue |

Smooth Muscle |
Lacks striations, us uninucleated, and consists of spindle shaped cells. (Involuntary) |
|
Cardiac Muscle Tissue |
Found only in the heart and consists of branching fibers that are connected to each other with intercalated discs. (Involuntary) |
|
Nervous Tissue |
Found in the brain, spinal cord, and nerves |
|
Organs |
Body structures composed of two or more different tissues that perform specific functions. |
|
