Benchmarks for Lecture Exam 1
Define and apply all terminology and word roots presented in lecture.
What is meant by the structural organization of living things?
Name and define each
unit within the structural organization of living things.
Give 4 ex. of each.
Organism (most complex)—all organ systems & gross anatomy; must have characteristics of
Ex. Human, Snake, Tree, Bacteria
Organ system—group of organs working together to perform a certain function.
Digestive, Nervous, Lymph
Organ—aggregate of tissues working together to perform a task.
Ex. Heart, Liver, Skin, Skull
Tissue—group of cells working as one part—epithelial, muscle, connective, nervous
Cellular—smallest living units made of molecules.
Ex. muscle fiber, neuron, osteocyte, r.b. cell
Chemical—simplest form, ex. N, H
, CHO, or NO
Define and locate regions of the body and principal local areas comprising each region.

4. Identify the various body cavities and the organs found in each.
Mediastinum—Pericardium(heart), trachea, thymus gland, esophagus
Abdominal—Stomach, liver, gall bladder, pancreas, spleen, kidneys, intestines
Pelvic—urinary bladder, colon, rectum, uterus, ovaries
What is the general function of the membranes in the body?
Compare and contrast mucous and serous.
Give 6 examples of each.
—covers and protects other structures in the body
—line cavities that communicate with the exterior; epithelial surfaces kept
moist at all times (lubricated by mucus or other glandular secretions); lined by simple epithelium
that function in absorption and secretion.
Ex. digestive, reproductive, respiratory, and urinary
—line subdivisions of ventral body cavity; consists of mesothelium supported
by loose c.t.; pleural—lungs; peritoneum—organs below the diaphragm; pericardium—heart
Ex. visceral/parietal + pleura/pericardium/peritoneum
—both cover and protect tissues in the body; mucous is ciliated to move
objects around, secretes and absorbs, and has columnar epithelium; serous are squamous cells
Serous membranes can be either visceral or parietal.
Compare/contrast the two.
Describe, in specific terminology, the location of each serous membrane
