Q

Anabolism

A

The process in which smaller, simpler molecules are combined into larger, more complex substances the body can assemble (by utilizing energy), the complex chemicals it needs by combining small molecules derived from the foods eaten

Q

Catabolism

A

The process in which larger, more complex substances are broken down into smaller, similar molecules; also releases energy. The complex molecules found in foods are broken down so the body can use their parts to assemble the structures and substances needed for life

24
Q

Homeostasis

A

The state of steady internal conditions maintained by living things

25
Inferior
Describes a position below or lower than another part of the body proper; near or toward the tail
26
Lateral
Describes the side or direction toward the side of the body
27
Magnetic Resonance Imaging (MRI)
A noninvasive medical imaging technique in which matter exposed to magnetic fields and radio waves emit radio signals (precise imaging, no radiation)
28
Medial
Describes the middle or direction toward the middle of the body
29
Metabolism
The sum of all anabolic and catabolic reactions that take place in the body (both occur simultaneously and continuously)
30
Microscopic Anatomy
The study of structures that can be observed only with the use of a microscope or other magnification devices
31
Negative Feedback
A mechanism that reverses a deviation from the set point. Maintains body parameters within their normal range (homeostasis)
32
Normal Range
The restricted set of values that is optimally healthful and stable
33
Nutrient
A substance in foods and beverages that is essential to human survival
34
Organ
Two or more different tissues combine
35
Organ System
Two or more organs work closely together to perform the functions of a body system
36
Organism
Many organ systems work harmoniously together to perform the functions of an independent organism
37
Pericardium
The serous membrane that surrounds the heart in the pericardial cavity
38
Peritoneum
The serous membrane that surrounds several organs in the abdominopelvic cavity
39
Physiology
The scientific study of the chemistry and physics of the structures of the body and the ways in which they work together to support the functions of life
40
Plane
An imaginary two-dimensional surface that passes through the body
41
Pleura
The serous membrane that surrounds the lungs in the pleural cavity
42
Positive Feedback
Intensifies a change in the body's physiological condition rather than reversing it. Normal only when there is a definite end point
43
Positron Emission Tomography (PET)
A medical imaging technique involving the use of radiopharmaceuticals (substances that emit radiation that is short-lived and therefore relatively safe)
44
Posterior
Describes the back or direction toward the back of the body
45
Posterior Cavity
One of the largest body compartments, contains and protects delicate internal organs
46
Pressure
A force exerted by a substance that is in contact with another substance
47
Prone
A face-down orientation
48
Proximal
Describes a position in a limb that is nearer to the point of attachment or the trunk of the body
49
Regional Anatomy
The study of the interrelationships of all the structures in a specific body region. How muscles, nerves, blood vessels, and other structures work together to serve a particular body region
50
Renewal
???
51
Reproduction
The formation of a new organism from parent organisms
52
Responsiveness
The ability to adjust changes in our internal/external environment
53
Sagittal Plane
The plane that divides the body or an organ vertically into right and left sides
54
Section
A two-dimensional surface of a three-dimensional structure that has been cut
55
Sensor
Also referred to as a receptor, a component of a feedback system that monitors a physiological value (that is then reported to the control center)
56
Serosa
One of the thin membranes that cover the walls and organs in the thoracic and abdominopelvic cavities
57
Serous Membrane
One of the thin membranes that cover the walls and organs in the thoracic and abdominopelvic cavities
