Chapter 1 Flashcards
(61 cards)
Anatomy
Study of structure and shape of body and parts
Physiology
Study of how the body and its parts work and function
Gross Anatomy
Large structures easily observable
Microscopic Anatomy
very small structures can only be viewed with a microscope
Structural Organization
Chemical Cellular Tissue Organ Organ Systems organism
Organ System
Integumentary Skin Skeletal Muscular Nervous Endochrine Cardiocvascular Lymphatic Respiratory Digestive Urinary Reproductive
Integumentary Skin
forms the external body covering protects deeper tissue from injury helps regulate body temperature loacation of cutaneous receptors sweat and oil glands
Skeletal system
protects and supports body organisms provides muscle attachment for movement site of blood cell formation stores minerals
Muscular System
produces movement maintains posture produces heat
Nervous System
fast acting system responds to internal and external change activates muscles and glands
Endocrine System
slow acting systems secretes regulatory hormones growth reproduction metablolism
Cardiovascular System
transports materials in body via blood pumped by heart oxygen, carbon, dioxide, nutrients, wastes
Lymphatic system
returns fluids to blood vessels cleanses the blood involved in immunity
Respiratory system
keeps blood supplied with oxygen removes carbon dioxide
Digestive System
breaks down food allows for nutrient absorption into blood eliminates indigestible material
Urinary System
eliminates nitrogenous wastes maintains acid base balance regulates water and electrolytes
Reproductive System
produces offspring testes produce sperm Ovaries produce eggs
Functions for Life
Maintain boundaries Movement Responsiveness Digestion metabolism Excretion Reproduction Growth
Maintain Boundaries
Internal environment is different from external integumentary system keeps fluid in bacteria out protects agains sun heat and chemicals
Movement
locomotion walking swimming facial expression movement of substances food and waste through alimentary canal blood urine
Responsiveness
ability to sense changes and react
Digestion
break down and absorption of nutrients
Metabolism
all chemical reactoins in body breakdown complex molecules to smaller build smaller to larger produce energy make body structures
Excretion
removing wastes produced during metabolic reactions and digestion primarily removed in urine and feces
