Glossary Words Flashcards
Anatomy
Is the study of the human body structures that can be seen with the naked eye as well as what the body is made up of; The science of the structure of organisms or their parts.
Physiology
Is the study of the functions and activities performed by the body’s structures.
Histology
Also known as microscopic anatomy:the study of tiny structures found in tissues.
Nucleus
Is the dense, active protoplasm found in the center of the cell. It plays an important part in cell reproduction and metabolism. Example : It’s the yolk of a raw egg.
Cytoplasm
Is the part of the protoplasm that exists outside of the nucleus and inside the cell wall. The protoplasm surrounds the nucleus and is needed for growth, reproduction, and self pair.
Cell membrane
Is the cell part that encloses and holds the protoplasm while still allowing soluble substances(e.g., nutrients or waste by-products), to enter and leave the cell.
Metabolism
Is a chemical process and that takes place in living organisms, through which the cells are nourished and carry out their activities.Metabolism occurs in two distinctly different phases.
Anabolism
Constructive metabolism;the process of combining smaller molecules to build larger and more complex molecules. The body focuses on storing water, food, and oxygen for later time when these substances will be needed for cell growth, reproduction, or repair.
Catabolism
The phase of metabolism is in which larger, more complex molecules are broken down within the cell to create small, simpler molecules. As a result of this breakdown , energy is released so that it may be used or stored later use.
