the 11 systems of the human body | integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, reproductive |
integumentary system | C/skin and structures derived from it: hair, nails, sweat glands, and oil glands || F/protects body, helps regulate body temp, helps make vitamin D, detects sensations |
skeletal system | C/bones and joints and their associated cartilages || F/supports and protects body; provides surface area for muscle attachments; houses cells that produce blood cells; stores minerals and lipids |
muscular system | C/muscles composed of skeletal muscle tissue || F/produces body movements; stabilizes body position; generates heat |
nervous system | C/brain, spinal cord, nerves, and special sense organs, such as the eye and ear || F/generates action potentials to regulate body activities; detects environmental changes; responds to changes with muscular contractions or glandular secretions |
endocrine system | C/hormone-producing glands and hormone-producing cells in several other organs || F/regulates body activities by releasing hormones, which are chemical messengers transported in blood from an endocrine gland to a target organ |
cardiovascular system | C/blood, heart, blood vessels || F/blood carries oxygen and nutrients to cells and CO2 and wastes away from cells; blood components help defend against disease and repair damaged blood vessels |
lymphatic system and immunity | C/lymphatic fluid and vessels; also includes spleen, thymus, lymph nodes, and tonsils || F/returns proteins and fluid to blood; carries lipids from GIT to blood; incubates lymphocytes, which protect against disease-causing organisms |
respiratory system | C/lungs and air passageways such as the pharynx (throat), larynx (voice box), trachea (windpipe), and bronchial tubes leading into and out of them || F/transferring O2 and CO2 in and out of lungs; regulating acid-base balance of body fluids |
digestive system | organs of the GIT, including mouth, pharynx, esophagus, stomach, small and large int, anus; also includes accessory organs, inc. salivary glands, liver, gallbladder, and pancreas || F/breakdown of food; absorption of nutrients; elimination of solid wastes |
urinary system | C/kidneys, ureters, urinary bladder, urethra || F/production, storage, and elimination of urine; eliminates wastes and regulates volume and chemical composition of blood; helps regulate production of red blood cells |
reproductive system | C/gonads (testes, ovaries), uterine tubes, uterus, vagina, epididymis, ductus deferens, penis || F/production, transport, and storage of gametes; production of hormones that regulate reproduction |
interstitial fluid | a type of extracellular fluid; the fluid that fills the narrow spaces between cells in tissues |
synovial fluid | the extracellular fluid in joints |
