47
Define serous fluid
Lubricating fluid secreted from the mesothelium that reduces friction during movement between the parietal and visceral layer. Allows organs to glide easily over one another.
48
Define serous membrane
A membrane that lines a body cavity that does not open to the exterior. The external layer of an organ formed by a serous membrane. The membrane that lines the pleural, pericardial, and peritoneal cavities. Also called a serosa.
49
Define sign(s)
Any objective evidence of disease that can be observed or measured, such as a lesion, swelling, or fever.
50
Define superficial
Located on or near the surface of the body or an organ. Also called external.
51
Define superior
Toward the head or upper part of a structure. Also called cephalic or cranial.
52

69
Structural changes (gross to microscopic) associated with disease.
Pathological anatomy (A)
70
Functional changes associated with disease and aging.
Pathophysiology (P)
71
Body structures that can be visualized with x-rays.
Radiographic anatomy (A)
72
Specific regions of the body such as the head or chest.
Regional anatomy (A)
73
Functions of the kidneys.
Renal physiology (P)
74
Functions of the air passageways and lungs.
Respiratory physiology (P)
75
Surface markings of the body to understand internal anatomy through visualization and palpation (gentle touch).
Surface anatomy (A)
76
Structure of specific systems of the body such as the nervous or respiratory systems.
Systemic anatomy (A)
77
Place the following in hierarchical sequence from lowest to highest: cell (cellular), organ, organism, chemical, system, tissue.
1. Chemical level 2. Cellular level 3. Tissue level 4. Organ level 5. System level 6. Organismal level (organism)
78
List the seven characteristics of living things.
1. Cells 2. Metabolism 3. Irritability 4. Growth 5. Reproduction 6. Differentiation 7. Movement
79
Define Cells
The basic structural and functional units of an organism that are composed of chemicals. Also the smallest living units in the human body.
80
Define Metabolism
The sum of all the chemical processes that occur in the body. Also in two phases Catabolism (breakdown of complex chemical substances) and Anabolism (Building up of complex chemical substances)
81
Define Irritability
The body’s ability to detect and respond to | changes. Also known as responsiveness. (an increase in body temperature during a fever).
82
Define Growth
An increase in body size that results from an increase | in the size of existing cells, an increase in the number of cells, or both.
83
Define Reproduction
(1) the formation of new cells for tissue growth, repair, or replacement, or (2) the production of a new individual. (Increase in numbers).
84
Define Differentiation
The development of a cell from an unspecialized to a specialized state. (A single fertilized human egg (ovum) develops into an embryo, and then into a fetus, an infant, a child, and finally an adult).
85
Define Movement
Includes motion of the whole body, individual organs, single cells, and even tiny structures inside cells. (After you eat a meal that contains fats, your gallbladder contracts and releases bile into the gastrointestinal tract to help digest). them.)
86
Compare the frequency and contribution of negative feedback systems with the frequency and contribution of positive feedback systems in the body.
Negative feedback systems will reverse the original stimulus (if getting hotter, it will get colder to return normal temp). It is the most common feedback system. Positive feedback systems will strengthen the change until the cycle breaks (giving birth with oxytocin). Sometimes its actions do not deal directly with maintaining homeostasis.
