Term | Definition | Components within System |
---|---|---|
Integumentary system | Produces vitamin D and regulates body temperature. Protects the body from the external environment and retains water. | Skin, hair, nails, and glands |
skeletal system | Supports the body and protects internal organs. Produces blood cells and stores calcium salts. | Bones, cartilages, ligaments, and joints. |
Muscular system | Produces movement, Controls body openings and generates heat. | Skeletal, smooth, and cardiac muscles. |
Nervous system | Regulates body functions via nerve impulses. | Brain, spinal cord, neurons, and neuroglial cells |
endocrine system | Regulates body functions via chemicals called hormones. | Pituitary, hypothalamus, pineal, thyroid, parathyroid, thymus, adrenal, pancreas, ovaries and testes glands |
cardiovascular system | Pumps and delivers oxygen- poor blood to the lungs and oxygen-rich blood to the tissues. Transports cells, nutrients and other substances. | Heart, blood vessels, and blood |
lymphatic system | Returns excess tissue fluid to the cardiovascular system Provides immunity (protection against disease. | Lymphatic vessels, lymphatic tissue, and lymphatic organs such as tonsils, lymphatic nodes, spleen, and thymus |
Respiratory system | Delivers oxygen to the blood and removes carbon dioxide from the body. | Nose, nasal cavity, pharynx, larynx, trachea, bronchi, and lungs. |
Digestive system | Mechanically and chemically digests food materials. Regulates fluid, electrolytes, and acid-base balance. | Mouth, pharynx, esophagus, stomach, small intestine, large intestine, and the accessory organs such as teeth, tongue, salivary glands, liver, gallbladder, and pancreas. |
urinary system | Filters and removes metabolic wastes from the blood. | Kidneys, ureters, urinary bladder, and urethra. |
reproductive system (male) | produces and transports sperm and secretes hormones such as testosterone. | testes, scrotum, duct system, penis, and accessory sex glands such as seminal vesicles, prostate, and bulbourethral glands. |
Reproductive system (female) | Site of fertilization of oocyte and growth and development of the embryo and fetus | Ovaries, uterine tubes, uterus, vagina, female external genitalia, and mammary glands. |
visceral layer | inner layer; touches the organ | |
parietal layer | outer layer; attaches to surrounding structures | |
serous fluid | between the layers; lubricates to prevent friction | |
oblique plane | used to study a section at an angle | |
frontal plane | (vertical plane) divides the body/part into anterior and posterior parts | |
transverse plane | (horizontal plane or cross section) divides the Body/part into a superior and inferior part | |
parasagittal plane | divides into unequal sections | |
midsagittal plane | (median plane) divides into equal sections | |
sagittal plane | divides the body/part into right and left sections | |
cranial cavity | Is in the dorsal cavity.... houses the brain the skull forms protection around the organ | |
spinal or vertebral cavity | is in the dorsal cavity houses the spinal cord the vertebrae protects this organ | |
thoracic cavity | is in the ventral cavity houses organs within 3 smaller cavities, is formed by the ribcage houses the heart(pericardial cavity), lungs(pleural cavity), esophagus and trachea(mediastinum cavity) | |
abdominopelvic cavity | is in the ventral cavity houses many organs no bones protect this area | |
Dorsal body cavity | found on posterior side of the body contains 2 subcavitities; cranial cavity and spinal/vertebral cavity | |
ventral body cavity | found on anterior side of body contains 2 main divisions separated by the diaphragm; thoracic cavity and abdominopelvic cavity | |
pelvic cavity | contains the bladder, reproductive organs and some GI organs | |
abdominal cavity | contains the gastrointestinal(GI) systems | |
parietal layer | outer layer; attached to surrounding structures | |
visceral layer | inner layer; touches the organ | |
serous fluid | between the layers; lubricates to prevent friction |
