Anatomy
Refers to the functions of an organism, and it examines the chemical or physical functions that help the
body fuction appropriately. - Physiology
All parts of the human body are build of individual units called: - Cells
Groups of similar cells are arranged into: - Tissues
Different tissues are arranged into: - Organs
Organs working togther form: - Organ Systems
The human body has twelve organ systems that govern: - Circulation, digestion, immunity, hormones,
movement, support, coordination, urination, excretion, reproduction, respiration, and general
protection.
Body Cavities - Different hollow spaces that house organs in the body.
Cranial Cavity - The cranial cavity is surrounded by the skull and contains organs such as the brain and
pituitary gland.
Thoracic Cavity - The thoracic cavity is encircled by the sternum (breastbone) and ribs. It contains organs
such as the brain and pituitary gland.
Abdominal Cavity - The abdominal cavity is separated from the thoracic cavity by the diaphragm. It
contains organs such as the stomach, gallbladder, liver, small intestines, and large intestines. The
abdominal organs are held in place by a membrane called the peritoneum.
Pelvic Cavity - The pelvic cavity is enclosed by the pelvis, or bones of the hip. It contains organs such as
the urinary bladder, urethra, ureters, anus, and rectum. It contains the reproductive organs as well. In
females, the pelvic cavity also contains the uterus.
Spinal Cavity - The spinal cavity is surrounded by the vertebral column. The vertebral column has five
regions: cervical, thoracic, lumbar, sacral, and coccygeal. The spinal cord runs through the middle of the
spinal cavity.
The three primary planes of the human body are: - frontal, saggital, and transverse.
Frontal/Coronal plane: - a vertical plane that divides the body or an organ into a front (anterior) and
back (posterior) portions.
Saggital/Lateral plane: - a vertical plane that divides the body into right and left parts
Transverse plane: - a horizontal plane that divides the body into superior (upper) and inferior (lower)
portions [Show Less]
