Science Test 2
Nervous Tissue
carries messages to and from the brain
Muscle Tissue
causes movement
Which is NOT a type of human tissue? a. connective b. meristem c. muscle d. nervous
b. meristem
Connective Tissue
provides structure and support and often connects other types of tissue together
Organization
An organism is made of organ systems, organs, tissues, and cells that all function together and enable the organism's survival.
Levels of Organization
Cell Tissue Organ Organ System Organism
Organ System
Circulatory System; a group of organs that work together
Cell
Every living thing is made up of cells
Organisms
Multicellular organisms usually have many organ systems. These systems work together to carry out all the jobs needed for the survival of the organisms. In the human body, there are many major organ systems. Each organ system depends on the others and cannot work alone. Example: the cells in the muscle tissue of the stomach cannot survive without oxygen. The stomach cannot get oxygen without working together with the respiratory and circulatory systems.
Tissue
Muscle; a group of cells that work together to perform a task
Organ
Stomach; A group of tissues to perform a job
Tissue
a group of similar types of cells that work together to carry out specific tasks.
Epithelial Tissue
forms the protective outer layer of the skin and the lining of major organs and internal body cavities
Organ Systems (usually organs do not function alone)
groups of different organs that work together to complete a series of tasks. Example: digestive system is made of many organs including the stomach, the small intestine the liver, and the large intestine. These organs and others all work together to break down food and take it into the body. Blood absorbs and transports nutrients from broken down food to cells throughout the body.
Organs
groups of different tissues working together to perform a particular job. Example: stomach is an organ specialized for breaking down food. It is made of all four types of tissue: muscle, epithelial, nervous, and connective. Each type of tissue performs a specific function necessary for the stomach to work properly. Layers of muscle tissue contract and break up pieces of food, epithelial tissue lines the stomach, nervous tissue sends signals to indicate the stomach is full, and connective tissue supports the stomach wall.
