Cardiovascular system
Organs: arteries and veins
Function: transport nutrients
Lymphatic
Organs: tonsils,thymus,spleen, lymph nodes, lymphatic vessels
Function: remove unwanted substance and recycle fluid to the blood
Respiratory system
Organs:pharynx,nose,trachea,larynx,bronchi,lungs
Function: exchange has b/t environment and blood
Digestive system
Organs: mouth,pharynx,salivary glands, esophagus, liver,stomach,pancreas,gallbladder,colon,small intestine
Function:prepare food for absorption into the bloodstream and eliminate solid waste from body
Urinary system
Organs: kidneys,ureters, bladder, urethra
Function: remove nitrogenous wastes and excess water and salt from bloodstream
Female reproductive system
Organs: mammary glands, Fallopian tubes, uterus, ovary, Vagina
Function: provide for creation of new indv.
Male reproductive system
Organs: vas deferents, testis, prostate, urethra, penis
Function: provide for creation of new indv.
Nervous system
Organs: Brian, spinal cord, nerves
Function:control homeostasis, process information and initiate body responses
Endocrine system
Organs: pituitary gland, thymus, thyroid gland, adrenal gland, pancreas, ovary,testis
Function: control homeostasis by releasing hormones into the bloodstream
Musculoskeletal
Organs: bone, muscle, joint, tendon
Integumentary
Organ: hair, skin, nails
Function: protect body from fluid loss,injury and infection
Anatomical position
Erect posture, face forward, arms at side, palms facing forward, legs together, feet pointing forward
Directional terms always in relation to anatomical position
-ior or -al
Pertaining to
Superior,Super/ior
Toward the head or upper part of body
Inferior,Infer/ior
Away from the head or toward the lower part of body
Anterior,Anter/ ior (ventral)
Toward the front or belly side
Posterior,Poster/ior (dorsal)
Toward the back
Medial, medi/al
Toward the midline
Lateral, later/al
Toward the side
Superficial, super/ficial
External, toward the body surface
Proximal, proxim/al
toward the origin of attachment to the trunk
Distal, dist/al
Away from the origin of attachment to the trunk
Coronal or frontal plane
Verticle plane passing through side to side, dividing into anterior and posterior
Sagittal plane
Vertical plane dividing the body into left and right portions
Transverse plane
Divides the body into superior and inferior portions
RUQ,LUQ,RLQ,LLQ
Right and left, lower and upper quadrants
Viscera
Cavities’ internal contents
Dorsal cavity
Cranial and spinal cavities
Central cavity
Thoracic cavity- superior to diaphragm
Abdominopelvic cavity-inferior to diaphragm
Pericardial cavity (thoracic cavity)
Cavities containing the heart
Pleural cavities-pertaining to the ribs
Mediastinum (thoracic cavity)
Heart, large blood vessels and thymus gland
Abdominal cavity
Liver,stomach,pancreas,spleen, most small and large intestine
Pelvis cavity
Bladder,reproductive organs
Etiology
The cause of a disease
CT (CAT) SCAN
Computed tomography scanning- Multiple x rays and computer enchanters for a 3D image
PET SCAN
Position emission tomography- detects journey of radioactive substance, detects areas of high metabolism (tumors)
MRI
Magnetic resonance imaging- 3D image, magnets respond to hydrogen atoms
Ultrasound imaging (sonography)
Pulsating sound waves, can detect different densities
