What are the levels of organization (in order) | 1. Chemical 2. Organelle 3. Cellular 4. Tissue 5. Organ 6.System 7.Organism |
What is a chemical reaction? | interaction between 2 or more atoms that occurs as a result of activity between electrons in their outermost energy levels |
What is an ionic bond? | formed by transfer of electrons; strong force that binds positively and negatively charged ions together |
What is a covalent bond? | Formed by sharing of electron pairs between atoms |
What is extracellular matrix (ECM)? | Fluid environment of the body- complex, nonliving material between cells in a tissue. Consists of water, proteins, and proteoglycans, |
What do different tissue types determine? | Structure and function of organs and systems |
What are the 5 main functions of epithelial tissue? | Protection, sensory function, secretion, absorption, and excretion |
What is the general function of connective tissues? | Connects, supports, and protects |
Functions of the skin? | Protection, surface film, sensation, flexibility, excretion, hormone production, immunity, homeostasis of body temperature |
What are the 5 structural bones? | Long boness. short bones, flat bones, irregular bones, and sesamoid bones |
What does a compact bone contain? | Many cylindar shaped structural units called osteons. Osteons permits delivery of nutrients and removal of waste products |
What does a cancellous bone contain? | Contains trabeculae. Where nutrients are delivered and waste products removed by diffusion |
Why is calcium critical for bones? | The bone is the storage of 98% of the body's calcium levels. It helps maintain calcium levels. |
