(18 cards)
Cells
The basic structural and functional units of all living organisms
Organelles
Structures inside cells that carry out particular functions
Tissues
Composed of a group of similar cells and the materials surrounding them
Organ
Composed of two or more tissue types that perform one or more common functions
Organ system
Group of organs that together perform a common function or set of functions
Integumentary system
Provides protection, regulates temperature, prevents water loss, and helps produce vitamin D. Consists of skin, hair, nails, and sweat glands
Skeletal system
Provides protection and support, allows body movements, produces blood cells, and stores. Minerals and adipose. Consists of bones, associated cartilages, ligaments, and joints
Muscular System
Produces body movements, maintains posture, and produces body heat. Consists of muscles attached to the skeleton by tendons
Nervous system
A major regulatory system that detects sensations and controls movements, physiological processes, and intellectual functions. Consists of the brain, spinal cord, nerves, and sensory receptors
Endocrine system
A major regulatory system that influences metabolism, growth, reproduction, and many other functions. Consists of glands, such as the pituitary, that secrete hormones
Cardiovascular system
Transports nutrients, waste products, gases and hormones throughout the body. Plays a role in the immune response and the regulation of body temperature. Consist of the heart, blood vessels and blood
Lymphatic system
Removes foreign substances from the blood and lymph, combat’s disease, maintains tissue fluid balance and absorbs dietary fats from the digestive tract. Consists of the lymphatic vessels, lymph nodes, and other lymphatic organs
Respiratory system
Exchanges oxygen and carbon dioxide between the blood and air and regulates blood pH. Consists of the lungs and respiratory passages
Digestive system
Performs the mechanical and chemical processes of digestion, absorption of nutrients, and elimination of wastes. Consists of the mouth, esophagus, stomach, intestines, and accessory organs
Urinary system
Removes waste products from the blood and regulates blood pH, I on balance, and water balance. Consists of the kidneys urinary bladder, and ducts that carry urine
Female reproductive system
Produces oocytes and is the site of fertilization and fetal development: produces milk for the newborn: produces hormones that influence sexual function and behaviors. Consists of the ovaries, uterine tubes, uterus, vagina, memory glands, and associated structures
Mail reproductive system
Producers and transfers sperm cells to the female and produces hormones that influence sexual functions and behaviors. Consists of the testes, accessory structures, ducts, and penis
Organism
Any living thing considered as a whole
