Anatomy
Study of organs and systems of the body
Gross anatomy
Study of the structures that can be seen with the naked eye
Microscopic anatomy
Study of structures too small to be seen except through a microscope
Physiology
Study of the functions these organs and systems perform
Histology
Another term for microscopic anatomy
Building blocks of the human body
Cells, tissues, organs, body systems
Cells
Basic units of living matter (life)
Cells vary in:
Size, shape, color, function
Protoplasm
Gel like substance containing water, salt and nutrients obtained from food
Cells are composed of
Protoplasm
Basic parts of most cells
Nucleus, cytoplasm, cell membrane
Nucleus
Control center
Cytoplasm
Production center
Cell membrane
Outer surface of cell
Mitosis
When cells grow and divide
Metabolism
Cells receive nutrients for growth and reproduction
Anabolism
Building up or storing
Catabolism
Breaking down or releasing energy
Catabolism
Breaking down or releasing energy
2 phases of metabolism
Anabolism and catabolism
2 phases of metabolism
Anabolism and catabolism
Tissues
Groups of cells of the same kind
5 types of tissues
Epithelial, connective,nerve,muscular, liquid
Epithelial tissue
Covers and protects body surfaces and internal organs
Connective tissue
Supports, protects, and holds the body together
Nerve tissue
Coordinates body functions in addition to carrying messages to and from the brain and spinal cord
Muscular tissue
Contracts when stimulated to produce motion
Muscular tissue
Contracts when stimulated to produce motion
Carries food, waste products,and hormones
Organs
