Camponeschi - human body targets 1-4

cell specialization when a cell is specifically designed to carry out one specific function
examples of cell specialization nerve cell, bone cell, involuntary muscle cell, voluntary muscle cell, red blood cell
describe the cell specialization of a nerve cell and how the STRUCTURE helps the FUNCTION nerve cell - (structure -->) has long branches that reach out to (function -->) send messages throughout body. The braches help the messages to be sent efficiently (fewer cells are needed allowing messages to be sent quickly)
describe the cell specialization of a voluntary muscle cell and how the STRUCTURE helps the FUNCTION (structure -->) has long fibers that can shorten a great deal and pull with a great force (function -->) to move bones. The long fibers and great force allow the body to move limbs with a large motion and with great power
describe the cell specialization of a red blood cell and how the STRUCTURE helps the FUNCTION (structure -->) small and donut shaped which helps the cell fit through small blood vessels and travel throughout the body with ease. (structure -->) has hemoglobin which oxygen sticks to (function -->) helping it easily bring oxygen to body cells
Is cell specialization seen in unicellular or multicellular organsisms multicellular organisms
What is the benefit of cell specialization It allows the organism to be larger, live away from food and water, do survival jobs more efficiently.
homeostasis keeping the body's internal environment (insides) stable regardless of what is happening outside
What are some examples of homeostasis Keeping the body at the same internal temperature. Keeping the needed amount of water in the body. Keeping the needed amount of food/energy in the body. Preventing the entrance of bacteria and viruses.
When you are cold (and about to be out of homeostasis), how does the body respond to maintain internal body temperature? shivering of the muscles creates friction and generates heat keeping the body warm.
when your body is getting low on energy (about to be out of homeostasis), how does the body respond? You feel hungry, which encourages you to eat to help restore energy levels.
What are the levels of organization of the human body (in order) cells, tissue, organs, organ systems, whole body.
could a cell from a multicellular organism survive on its own? no - these cells are much too specialized for only one very specific job
How do cells relate to tissue? one type of tissue is made of one type of cell working together doing one job. ex: muscle tissue is made of muscle cells.
How is tissue related to organs? several DIFFERENT types of tissue work together and make up one organ. ex: the heart is made of muscle tissue, connective tissue, nerve tissue, and epithelial tissue
How are organs related to organ systems? an organ system is made of many DIFFERENT organs working together to perform functions of the system.
How are the levels of organization of the body related? a smaller level makes up a larger level. the smaller levels work together to perform a task/s of the larger level
