U1: Body Systems
Anatomy Systems
Term | Definition |
---|---|
Integumentary System Physiology: | Forms external body covering, protects deeper tissue from injury, synthesizes Vitamin D, site of cutaneous receptors (pain, pressure, etc), sweat and oil glands |
Integumentary System Major Organs: | Hair, Skin, Nails |
Skeletal System Physiology: | Provides framework the muscles use to cause movement, blood cells are formed within bones, stores minerals |
Skeletal System Major Organs: | Joints and Bones; Femor, Fibula, Carpal |
Muscular System Physiology: | Allows manipulation of the environment, locomotion (ability to move), facial expressions; maintains posture, produces heat |
Muscular System Major Organs: | Skeletal Muscles; Biceps, Triceps, Quads |
Nervous System Physiology: | Fast acting control system of the body, responds to internal and external changes by activating appropriate muscles and glands |
Nervous System Major Organs: | Brain, Nerves, Sensory Receptors, Spinal Cord |
Endocrine System Physiology: | Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use (metabolism) by body cells |
Endocrine System Major Organs: | Thyroid gland, thymus, Pineal gland, Pituitary gland, Adrenal gland, Pancreas, Ovary, Testis |
Cardiovascular System Physiology: | Blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc; the heart pumps blood |
Cardiovascular System Major Organs: | Heart and Blood vessels; Veins, Arteries, Capillaries |
Lymphatic System Physiology (Immunity): | Picks up fluid leaked from blood vessels and returns it to blood; disposes of debris in the lymphatic stream; houses white blood cells (lymphocytes) involved in immunity; mounts attacks against foriegn substances in the body |
Lymphatic System Major Organs: | Red bone marrow, Thymus, Lymphatic vessels, Thoracic duct, Spleen, Lymph Nodes |
Respiratory System Physiology: | Keeps blood constantly supplied with oxygen and removes carbon dioxide; gaseous exchanges occur through walls of air sacs of the lungs |
Respiratory System Major Organs: | Nasal Cavity, Pharynx, Larynx, Lungs, Bronchus |
Digestive System Physiology: | Breaks down food into absorbable units; enter blood stream; distributed to body cells indigestable food "stuff" eliminated into feces |
Digestive System Major Organs: | Oral cavity, Esophagus, Liver, Stomach, Small Intestine, Large Intestine, Rectum, Anus |
Urinary System Physiology: | Eliminates nitrogenous wastes from the body; regulates water, electrolytes and acid-base balance in the blood |
Urinary System Major Organs: | Kidney, Ureter, Urinary Bladder, Urethra |
Reproductive System Male Physiology: | Function in production of offspring. Testes produce sperm; male sex hormone; ducts and glands aid in delivery of sperm to female reproductive tract |
Reproductive System Female Physiology: | Ovaries produce eggs and female sex hormones; other sites are for fertilization and development of fetus |
Reproductive System Male Major Organs: | Prostate Gland, Penis, Testis, Scrotum, Ductus Deferens |
Reproductive System Female Major Organs: | Mammary Glands (In breasts), Ovary, Uterus, Vagina, uterine tube |
