A&P 1 Flashcards
The integumentary system is the organsystem that protects the body from various kinds of damage, such as loss of water or abrasion from outside. The system comprises the skin and its appendages (including hair, scales, feathers, hooves, and nails).
protects and support body organs and provides a framework the muscle use to cause movement.Blood cells are formed within the the bones.Bones store minerals.
Allows manipulation of the environment , locomotion and facial expression , Mantains posture and produces heat
As the fast acting control system of the body , it responds to internal and external changes by activating appropriate muscle and glands
Gland secrete hormones that regulate process such as growth ,reproduction and nutrient use (metabolism by body cells
Blood vessels transport blood , which carries oxygen ,carbon dioxide, nutrients waste, etc.The heart pumps blood
picks up fluid from blood vessels and return it to blood .Disposes of debris in the lymphatic stream .Houses white blood cells (lymphocytes )involved in immunity
keeps blood constantly supplied with oxygen and removes carbon dioxide
breaks down food into more absorbable units that enter the blood for distribution to body cells to indigesable food stuff are eliminated as feces.
Eliminates nitrogenous wastes from the body. Regulates water electrolyte and electrolyte and acid base balance of the the blood.
breaking down substances into simpler building blocks
synthesizing more complex cellular from simpler substances
is the ability to maintain relatively stable internal conditions even though the the outside world changes continuously
Process of homeostatic control
#2. control system
#3 afferent pathway

Away from the midline of the body l on the outer side of
the arms are lateral to the chest
Between a more medial and a more lateral structure
The collar bone is intermediate between the breastbone and shoulder
Closer to the origin of the body part or the point or the attachment of the a limb to the trunk
the elbow is proximal to the wrist
Farther from the origin of the body part or the point of attachment of a limb to the body trunk
the knee is is distal to the tigh
Superficial (external )
toward or at the body surface
The lungs are deep to the skin
Is a vertical plane that divides the body into right and left parts
Median plane or mid sagittal plane
Lies exactly in the middle of the body
divides the body into unequal halves
frontal and coronal planes
DORSAL AND VENTRAL CAVITIES
ABDOMINO PELVIC CAVITY, ABDOMIAL
Ventral cavity:houses the pleura cavities which encases the lungs .
Superior Mediastenum houses the
Protects the fragile nervous system organs,has two subdivisions the cranial and the vertebral cavities
VENTRAL BODY CAVITY
HAS TWO MAJOR SUBDIVISIONS THE THORACIC AND THE ABDOMINO PELVIC AREA CAVITY .IT HOUSES THE INTERNAL ORGANS CALLED VISCERA OR VISCERAL ORGANS
PELURAL CAVITIES IN THE THORACIC CAVITY ENCLOSE ?
THE MEDIAL MEDIASTENUM IN THE THORACIC CAVITY ENCLOSE ?
IT CONTAINS THE PERICARDIAL CAVITY ,WHICH IT ENCLOSES THE HEART , ESOPHAGUS and THE THRACHEA
The walls of the ventral cavity and the outer surfaces of the organs on the ventral cavity are protected by a thin double layer membrane called serosa or serous membrane
Regional name =
The axial part is:
Head neck and trunk
The appendicular part is:
Sternal ,Axillary ,mamary
Regional terms Ventral (anterior)
Regional terms dorsal(posterior)
Pericardial cavity encloses?
Encloses the heart and it also surrounds the other remaining thoracic organs (esophagus, trachea and others)
The abdominopelvic cavity
The abdominopelvic cavity is divided into the abdominal cavity and pelvic cavity.
Abdominal cavity contains the intestines,the stomach,spleen, liver and other organs.
The pelvic cavity contains the urinary bladder, some reproductive organs and rectum
The walls of the ventral body cavity and the outer surfaces of the organs it contains are covered by a thin double layer called the "serosa" or the serorus membrane
lines into the pericardial cavity and folds back as the visceral pericardium, which it cover the heart
line the walls of the of the thoracic cavity and the visceral pleurae cover the lungs.
is associated with the walls of the abodominopelvic cavity while the visceral peritoneum covers most of the organs within that cavity

The serous membranes
Are double thin layer composed of connective and epithelial tissue.they line the walls of the thoracic and abdominal cavities and then fold back to cover the organs within the cavities.A slippery serous fluid produced by the cells of the membrane is found in between the two layers. This fluid permits the free sliding of the two layers during movement. THE portion of the membrane attached to an organ is called the visceral layer. The external layer or the portion of the membrane that attaches the body wall is called the parietal layer.
