Abductors
muscles that draw a body part, such as a finger, arm, or toe, away from the midline of the body or of an extremity. in the hand, abductors separate the fingers.
absorption
the transport of fully digested food into the circulatory system to feed the tissues and cells.
adductors
muscles that draw a body part, such as a finger, arm, or toe, inward toward the median axis of the body or of an extremity. in the hand, a Duck Tours draw the fingers together
adipose tissue
a specialized connective tissue considered fat, which gives smoothness and Contour to the body and cushions and insulates the body.
adrenal glands
glands that secrete about 30 steroid hormones and control metabolic processes of the body, including the fight or flight response.
anabolism

angular artery
artery that supplies blood to the side of the nose.
anterior auricular artery
artery that supplies blood to the front part of the ear.
aorta
the body’s largest artery. They’re arterial trunk that carries blood from the heart to be distributed by Branch arteries through the body.
arteries arteries
thick walled muscular and flexible tubes that carry oxygenated blood from the heart to the capillaries throughout the body.
arterioles
small arteries that deliver blood to capillaries.
atrioventricular valves
abbreviated ATV, valves which are designed to prevent the blood from flowing back into the pumping chamber.
atrium
thin walled, upper chamber of the heart through which blood is pumped to the ventricles. There is a right atrium and a left atrium.
auricularis interior
muscle in front of the air that draws the ear forward.
auricularis posterior
muscle behind the ear that draws the ear backward.
auricularis superior
muscle above the ear that draws the ear upward.
auriculotemporal nerve
nerve that affects the external ear and skin above the temple, up to the top of the skull.
autonomic nervous system
abbreviated ANS, the part of the nervous system that controls the involuntary muscles, regulates the action of the smooth muscles, glands, blood vessels, and heart.
Axon
the extension of a neuron through which impulses are sent away from the cell body to other neurons, glands, or muscles.
belly
middle of a muscle.
biceps
muscle producing the Contour of the front and inner side of the upper arm
blood
nutritive fluid circulating through the circulatory system( heart, veins, arteries, and capillaries) to supply oxygen and nutrients to cells and tissues and to remove carbon dioxide and waste from them.
blood vessels
tube-like structures that transport blood to and from the heart, and to various tissues of the body, include arteries, arterioles , capillaries, venules, and veins.
