Tissue Level
Tissues (organization of similar cells)
Tissue types
Epithelial Tissue
Connective
Muscle
Nervous
Epithelial Tissue
Covers exposed surfaces
Lines body cavities
Connective tissue
protects, supports, and interconnects body parts and organs
Muscle Tissue
Produces Movement
Nervous Tissue
Conducts impulses for internal communication
Organ Level
2+ Tissue types combine into an organ
Organ System Level
conglomerate of similar organs to achieve a common function
Organismal Level
Body Systems function together to form an organism
Living thing charactaristics
Organization Metabolism Growth& Development Responsiveness Adaptation Regulation Reproduction
Organization
Organisms are organized
Metabolism
The ability to carry out chemical reactions to produce energy
Growth and Development
Living things grow larger and increase specialization in their function
Responsiveness
Living things respond to their environment
Adaptation
living organisms change anatomic structures/physiological process/behavioral traits to adapt to a situation
Regulation
Ability to maintain homeostasis
Reproduction
Organisms produce gametes to develop new living things
Organ Systems
Skeletal Integumentary System Muscular System Endocrine System Nervous system Cardiovascular system Respiratory Lymphatic system digestive system male reproductive system urinary system female reproductive system
Skeletal System
Supports and protects body
site of blood cell production
Integumentary System
protects and regulates body temperature.
Muscular System
Movement
Generates heat
