1: Organ Systems Flashcards
Integumentary system
Forms the external body covering, protects deeper tissues from injury. Synthesizes vitamin D, houses cutaneous receptors (pain, pleasure), sweat and oil glands
Skeletal system
Protects and supports body organs, provides a framework the muscles use for movement. Bones form blood cells and store minerals
Muscular system
Allows manipulation of environment, locomotion, and expression. Maintains posture and produces heat
Nervous system
Fast acting control system of the body, responds to internal and external changes by activating muscles and glands
Endocrine system
Glands that secrete hormones to regulate growth, reproduction, and nutrient use/metabolism by body cells
Cardiovascular system
Blood vessels that transport blood to carry oxygen, carbon dioxide, nutrients, waste, etc. Heart pumps blood
Lymphatic system
Picks up fluid leaked from blood vessels and returns it to blood, disposes of debris. Houses lymphocytes (white blood cells) involved in immunity
Respiratory system
Keeps blood supplied with oxygen and removes carbon dioxide, occurs through the walls of the air sacs of the lungs
Digestive system
Breaks down food into absorbable units that enter the blood for distribution to cells
Uniranry system
Eliminates nitrogenous wastes from the body, regulates water, electrolyte, and acid-based balance of blood
Male reproductive system
Production of offspring. Testes produce sperm and male sex hormone, ducts and gland deliver.
Female reproductive system
Ovaries produce eggs and female sex hormone, other structures serve as sites for fertilization and development. Mammary glands produce milk.
