multicellular organisms Flashcards
name all 5 systems
respiratory circulatory digestive musculoskeletal nervous
how does the respiratory system work?
and what are its major organs and tissues
exchanges o and co2 between blood and the external environment
lungs, windpipe, blood vessels, epithelial, muscle, nerve, connective
name 4 important differentiated cells and what they do
muscle: allows movement
epithelial: covers external surfaces of body, protects
nerve: controls and allows our 5 senses
connective: connects tissue together
what are the plant major organ systems?
flower, stem, leaves, shoot system, roots, roots system
order the following: tissue, organ system, cell, organisms, organ
organisms, cell, tissue, organ, organ system
what is a tissue?
a group of differentiated cells that work together to perform a specific function
what is an organ?
two or more tissues that work together to perform one or more functions
what is an organ system?
a group of organs that work together to perform related functions
how does the circulatory system work?
and what are its major organs and tissues?
transports nutrients, dissolved gases (o and co2) and wastes to and from individual cells in the organism
heart, blood vessels, epithelial, muscle, nerve, connective
how does the digestive system work?
and what are its major organs and tissues?
breaks food down into small particles (nutrients) that can be transported by the circulatory system to all cells
mouth, pancreas, anus, small and large intestines, liver, stomach, esophagus, nerve, connective, epithelial, muscle
how does the musculoskeletal system work?
and what are its major organs and tissues?
provides structural support for body. protects internal structures from environment. plays a role in movement and locomotion
bones, muscles, epithelial, muscle, nerve, connective
how does the nervous system work?
and what are its major organs and tissues?
responds to changes in internal and external environment of body. coordinates functions for all systems
brain, spinal cord, sensory organs, nerve, epithelial, connective
