Lab Test 1 CH1 Flashcards
smallest unit of matter that has the characteristics of an element, eg H
Atom
two or more atoms, eg H2O
Molecule
more complex molecules, eg DNA
Macromolecule
collection of macromolecules that are microscopic structures within a cell
Organelle
smallest living structures that are the basic units of structure in an organism
Cell
groups of similar cells that perform a function
Tissue
groups of tissues that perform a function
Organ
groups of organs that work together to perform a function
Organ system
a living being; highest level of organization
Organism
Provides protection, regulates body temperature, site of cutaneous receptors and some glands, synthesizes vitamin D, prevents water loss.
Integumentary
Provides support and protection, site of hemopoiesis (blood cell production), stores calcium and phosphorus, provides sites for muscle attachments.
Skeletal
Produces body movement, generates heat when muscles contract.
Muscular
A regulatory system that controls muscles and some glands and responds to sensory stimuli. Also responsible for consciousness, intelligence, memory.
Nervous
Consists of glands and cell clusters that secrete hormones, which regulate development, growth and metabolism; maintain homeostasis of blood composition and volume, control digestive processes, and control reproduction.
Endocrine
Consists of the heart and blood vessels; the heart moves blood through blood vessels in order to distribute hormones, nutrients, gases, and pick up waste products.
Cardiovascular
Transports and filters lymph (interstitial fluid transported through lymph vessels) and participates in an immune response when necessary.
Lymphatic
Responsible for exchange of gases (oxygen and carbon dioxide) between blood and the air in the lungs.
Respiratory
Filters the blood to remove waste products and biologically active molecules, concentrates waste products in the form of urine, and expels urine from the body.
Urinary
Mechanically and chemically digests food materials, absorbs nutrients, and expels waste products.
Digestive
Produces male sex cells (sperm) and male hormones (e.g., testosterone), transfers sperm to the female.
Male Reproductive
Produces female sex cells (oocytes) and female hormones (e.g., estrogen and progesterone), receives sperm from male, site of fertilization of oocyte, site of growth and development of embryo and fetus, produces and secretes breast milk for nourishment of newborn.
Female Reproductive
