Structural Organization of Human Body, Chapter 1: The Human Body
Terms in this set (76)
1 Chemical level
Nothing is alive
Atoms, molecules, and compounds are part of it
Four atoms make up body
Have 2 or more atoms (O2)
Have 2 or more elements (H2O)
Water, salt, acids , bases
ENABLE FUNCTIONING OF BODY
Carbs, lipids, nucleic acids, proteins,
MAKE UP PHYSICAL STRUCTURE
2 Cellular level
Red blood cell(RBC
White blood cell(WBC)
3 Tissue level
Group of cells working for same function
Four major tissues
1.epithelial=acts as covering or lining(skin)
4 organ level
Heart, stomach, liver, lungs, etc.
tissues joined together to make organs (sentenses to paragraphs)
Forms the external body covering; protects deeper tissue from injury; synthesizes Vitamin D; location of cutaneous receptors (pain, pressure, etc.) and sweat and oil glands.
Consists of bones, cartilages, ligaments, and joints. Protects and supports body organs; provides a framework the muscles use to cause movement; blood cells are formed within bones; stores minerals. (bone,cartaliage,joint)
Allows manipulation of the environment, locomotion, and facial expression; maintains posture; produces heat.
Brain, sensory receptor, spinal cord, nerves. Fast-acting control system of the body; responds to internal and external changes by activating appropriate muscles and glands.
Fast-acting control system.
Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use by body cells.
Controls body activities as well, but in a slower way.
Heart and blood vessels. Blood vessels transport blood, which carries oxygen, carbon dioxide nutrients, wastes, etc.; the heart pumps bloods.
Picks up fluid leaked from blood vessels and returns it to blood; disposes of debris in the lymphatic stream; houses white blood cells involves in immunity.
Sister system to circulatory.
Keeps blood constantly supplied with Oxygen and removes carbon dioxide; the gaseous exchanges occur through the wall of the air sacs of the lungs.
Breaks food down into absorbable units that enter the blood for distribution to body cells; indigestible food stuffs are eliminated as feces.
Eliminates nitrogen-containing wastes from the body; regulates water, electrolyte, and acid-base balance of the blood.
Testes produce sperm and male hormone; ducts and glands aid in delivery of viable sperm to the female reproductive tract. Ovaries produce eggs and female sex hormones; remaining structures serve as site for fertilization and development of the fetus. Mammary glands of female breast produce milk to nourish the newborn.
Superior (cranial or cephalad)
Toward the head end or upper part of a structure or the body; above.
Away from the head end or toward the lower part of a structure or the body; below.
Toward or at the front of the body; in front of.
Toward of at the backside of the body; behind.
Toward or at the midline of the body; on the inner side of.
Away from the midline of the body; on the outer side of.
Between a more medial and a more lateral structure.
Close to the origin of the body part or the point of attachment of a limb to the body trunk.
Farther from the origin of a body part or the point of attachment of a limb to the body trunk.
Toward or at the body surface.
Away from the body surface; more internal.
chest bone area
anterior body trunk inferior to ribs
area overlying the pelvis anteriorly
area where thigh meets body trunk
anterior surface of elbow
posterior surface of elbow
lateral part of leg
heel of foot
shoulder blade region
area of spinal column
area between hips
the posterior surface of leg
divides body into left + right
divides the body into to = halves left and right
Frontal (coronal) plane
divides the body into anterior and posterior parts
horizontal division of the body into upper and lower portions
related organs that have same function (paragraphs to chapters)
A tendency to maintain a balanced or constant internal state/temp
unequal left and right parts
Passes through a body part at any angle among the three body planes
