Exam 1 Flashcards
Integumentary System
Protects the body, helps regulate body temperature
Skeletal System
Supports and protects organs, forms blood cells and stores minerals
Muscular System
Participates in body movements such as walking, maintains posture and produces heat
Nervous System
Generates nerve pulses to regulate body activities, detects changes in body environment and responds by causing muscular contractions or gland secretions
Endocrine System
Regulates body activities by releasing hormones
Cardiovascular System
Transports nutrients, gases and other substances
Lymphatic/Immune System
Returns proteins and fluid to blood, defends against disease
Digestive System
Achieves chemical and physical breakdown of food, absorbs nutrients
Respiratory System
Transfers oxygen from inhaled air to blood and carbon dioxide from blood to exhaled air, helps regulate acid-base balance of body fluids
Urinary System
Produces, stores and eliminates urine, eliminates wastes and regulates volume and chemical composition of blood
Reproductive System
Gonads produce gametes (sperm or oocytes), which unite to form a new organism, also release hormones
What two systems control homeostasis?
Nervous System and Endocrine System
Supine
Face Up
Prone
Face Down
Frontal (coronal) Plane
Divides the body into front and back portions
Sagittal Plane
Vertical plane that divides the body into right and left sides
Transverse (horizontal) Plane
Divides the body or an organ into upper and lower portions
Parasagittal Plane
Divides the body into unequal right and left sides
Midsagittal Plane
Divides the body into equal right and left sides
Oblique Plane
Passes through the body or an organ at an oblique angle
Ionic Bond
Attraction of a + ion to a - ion, bond formed for each ion to achieve a full electron shell
Covalent Bond
Formed by the sharing of electrons between two atoms, electrons aren’t gained or lost so its the strongest
Hydrogen Bond
Chemical bond between a molecule containing hydrogen and a molecule that is electron hungry, no transfer or sharing of electrons so they’re the weakest
Catabolism
Involves all of the metabolic processes that tear down biomolecules
Anabolism
Involves all of the metabolic processes that build biomolecules
