Human Body Tissues

• epithelial

• connective

• muscle

• nervous

Types of Human Body Tissues

connective: supports, protects, and gives structure to other tissues and organs in the body

muscle: movement is the main function

nervous: monitors and regulates the functions of the body

epithelial: form the covering of all body surfaces, line body cavities and hollow organs

Levels of Organization

Similar cells that are grouped together form tissue.

Groups of tissue working together form an organ.

Organs working together form an organ system.

Organ systems working together then help the organism live.

Levels of Organization cont.

cells -> tissues -> organs -> organ systems -> organism


Example:
neurons -> nerve tissue -> brain -> nervous system -> human

bone cells, skeletal tissue, bones, skeletal system, dog

muscle cells, muscle tissue, heart, circulatory system, human

stomach cells, stomach tissue, stomach, digestive system, chicken

skin cells, epithelial tissue, skin, integumentary system, frog

gill cells, bronchial tissue, gills, respiratory system, fish

lymph cells, lymph tissue, lymph nodes, immune system, human
