Chapter 2 Definitions Flashcards
Anabolism
Process of building up complex proteins from simpler substances
Catabolism
Process of breaking down complex foods into simpler substances
Metabolism
Anabolism+catabolism
Cell membrane
Semipermeable structure that surrounds and protects the cell
Chromosomes
Rode like structures containing regions of DNA called genes
Cytoplasm
Material inside the cell membrane that surrounds the nucleus
DNA
The basic structure of genes that directs cell activity and transmits genie information
(Deoxyribonucleic acid)
Endoplasmic reticulum
Protein factory where proteins are made from simpler materials
Golgi apparatus
Process factory where proteins are stored, modified, and transported
Lysosomes
Site of intracellular digestion containing to enzymes
Mitochondria
Energy factory for cell
Nucleus
The control center of the cell
Nucleolus
Site of RNA synthesis
Ribosomes
Site of protein synthesis
Adipose tissue
Collection of fat cells
Epithelial tissue
Consists of epithelium, endothelium, and mesothelium
Epithelium
Lines external and internal body surfaces
Endothelium
With lines the organs and blood vessels
Mesothelium
Lines cavities
Skeletal muscle
Striated and voluntary
Cardiac muscle
Striated and involuntary
Visceral muscle
Smooth and involuntary
Nerve tissue
Cells that conduct electrical impulses all over the body
Abdominal cavity
Cavity contains organs such as stomach and spleen
Thoracic
Cavity containing organs such as the heart and lungs
Anatomy
The form and structure of the body
Benign
Non-invasive
Cartilage
Flexible connective tissue attached to the bones of a joint
Diaphragm
Thin, muscular partition separating the thoracic and abdominal cavities
Endocrine glands
Glands that secrete hormones directly into the bloodstream
