Quiz 1 Flashcards
define anatomy
the science of body structures and the relationships among them
define physiology
the science of body functions
6 levels of organization
chemical, cells, tissue, organs, systems, organisms
what makes up an organ
2 or more different tissue types
name the 11 body systems
muscular, urinary, respiratory, digestive, endocrine, skeletal, lymphatic, integumentary, nervous, cardiovascular
components of integumentary system
skin, hair, nails, sweat/oil glands
functions of integumentary system
protection, temperature regulation, waste elimination, vitamin D, sensory detection, fat storage, provides insulation
components of skeletal system
bones, joints and associated cartilages
functions of skeletal system
provides support for the body, surface for muscles to attach to, mineral and lipid storage, has cells that produce blood cells
components of muscular system
skeletal muscle tissue
functions of muscular system
movement, posture, produces heat
components of nervous system
brain, spinal cord, nerves, specific sense organs (eyes, ears)
functions of nervous system
action potential to regulate homeostasis, interprets changes and responds by causing muscular contraction and gland secretion
components of the endocrine system
hormone producing glands (pineal, hypothalamus, thyroid, parathyroid, adrenal, pancreas, ovaries, testes)
function of the endocrine system
regulates homeostasis via hormone release
components of cardiovascular system
heart, blood, blood vessels
functions of cardiovascular system
pumps blood; circulates O2 and nutrients throughout the body via blood throughout the body; carries out CO2 and wastes, regulates pH, temp, water, defence, repair
components of lymphatic system
lymph, lymph vessels, spleen, thymus, lymph nodes, tonsils, cells for immune response (T and B cells)
functions of lymphatic system
returns proteins and fluid to blood, carries lipids, contains sites of maturation and proliferation of B and T cells
components of respiratory system
lungs and their passageways (pharynx, larynx, trachea, bronchial tubes)
functions of respiratory system
transfers O2 from inhaled air to blood, transfers CO2 from blood to exhaled air, regulates pH, produces sound via air passing through larynx
components of digestive system
GI organs; mouth, pharynx, esophagus, stomach, intestines, anus; includes accessory organs - salivary glands, liver, gallbladder, pancreas
functions of digestive system
chemical and physical breakdown of food, absorb nutrients, eliminate solid wastes
components of urinary system
kidneys, ureters, bladder, urethra
