1D From Cell to System Flashcards
(14 cards)
what are the 5 levels of structural organisation in multicellular organisms
cell - tissue - organ - system - organism
4 tissue types
muscle tissue, nervous tissue, epithelial tissue, connective tissue
3 types of muscle tissue
striated muscle tissue, cardiac muscle tissue, smooth muscle tissue
3 types of nervous tissue
bipolar interneuron, unipolar sensory neuron, multipolar moto neuron
epithelial tissue
include all cells that form the interface between the body and the external environment
epithelial tissue examples
epidermis, mucous membranes, lining of the gastrointestinal tract, airways, reproductive system, and exocrine glands
connective tissues
are fibrous tissues containing cells, separated by an extracellular matrix.
connective tissues examples
they include loose connective tissues (areolar Tissues), Adipose tissue, the dermis, ligaments, tendons, osseous tissue, cartilage, and blood
organs
organs structures in the body composed of various tissues ( often of all four tissue types) that together achieve an important function in the body
system
systems are arrangements of organs which work together to carry out a major purpose in the body.
major systems in the body
- respiratory system
- digestive system
- musculoskeletal system
- circulatory system

- rectum
- anus
- salivary glands
- liver
- gallbladder
- pancreas
the respiratory system includes
- mouth
