Medical Science I

 Community  Group of populations that live together in a defined area (Ex: businesses, people, pets, etc. in Alvin)  Population  Group of individuals of the same species that live in the same area (Ex: Latinos in Alvin)

 Organism  Individual form of life (ex: human)  Organ System  Group of organs that work together to perform a specific function (ex: digestive system)

 Organ  Group of tissues that work together to perform closely related functions (Ex: stomach)  Tissue  Group of similar cells that perform a particular function (Ex: Connective tissue)

 Cell  Basic structure of animals (Ex: muscle cell)  Nucleus  An organelle in the cell containing chromosomes (Ex: human nucleus with 46 chromosomes)

 Chromosome  Structures with chemical instructions divided in sections called genes (Ex: chromosome #3)  Gene  Sequence of DNA that codes for proteins and determines a trait (Ex: gene for eye color)

 DNA  Deoxyribonucleic acid
