1. Define the terms anatomy and physiology, and explain their relationship using an example of a human structure with its corresponding function.
- Anatomy is the study of the structures and relationship between body parts. Physiology is the study of the function of body parts and the body as a whole. The kidneys remove wastes and water from the blood.
2. List, in order from least to most complex, the levels of structural organization, discuss the relationship between the levels, and name an example at each level. - Atom- is the smallest particle of an element; it is the least complex level. Atoms combine with other atoms to form molecules. An example of an atom is Carbon.
- Molecules- is a particle composed of 2 or more joined atoms. Molecules combine with other molecules to form macromolecules. An example of a molecule is water.
- Macromolecules- a larger molecule. Macromolecules combine with other macromolecules to form organelles. An example of a macromolecules is lipids.
- Organelles- a small organ of a cell, which performs a particular function. Organelle form cells. An example of organelles is ribosomes.
- Cells- are the basic unit of structure and function of living organisms. Each cell has a set of organelles and performs a particular function. An example of cells is red blood cells.
- Tissue- a group of similar cells that performs a specialized function. Two or more tissues combine to form organs. An example of tissue is connective tissue.
- Organs- a structure consisting of a group of tissues that performs a specialized function. Two or more organs combine to form organ systems. An example of an organ is the heart.
- Organ systems- a group of organs that act together to carry on a specialized function. The eleven organ systems collectively form
