5
Perfectly
25
Protects and supports body organs, and provides framework for muscles
Skeletal System
26
Allows manipulation of the environment, locomotion and facial expression. Maintains posture and produces heat
Muscular System
27
Fast-acting control system of the body, it responds to internal and external changes by activating appropriate muscles and glands
Nervous System
28
Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use (metabolism) by body cells.
Endocrine System
29
Blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc. The heart pumps blood.
Cardiovascular System
30
Picks up fluid leaked from blood vessels and returns it to blood. Disposes of debris in the lymphatic stream. Houses white blood cells (lymphocytes) involved in immunity. The immune response mounts the attack against foreign substances within the body.
Lymphatic System
31
Keeps blood constantly supplied with oxygen and removes carbon dioxide. The gaseous exchanges occur through the walls of the air sacs of the lungs.
Respiratory System
32
Breaks down food into absorbable units that enter the blood for distribution to body cells and Indigestible foodstuffs are eliminated as feces.
Digestive System
33
Eliminates nitrogenous wastes from the body. Regulates water, electrolyte, and acid-base balance of the blood.
Urinary System
34
Overall function is production of offspring.
Reproductive System
35
Chemicals for energy and cell building
Nutrients
36
Major source of energy
Carbohydrates
37
Needed for cell building and cell chemistry
Protein
38
long-term energy storage minerals and vitamins: involved in chemical reactions as well as for structural purposes
Fats
39
Essential for release of energy from foods
Oxygen
40
Most abundant chemical in body; provides the watery environment needed for chemical reactions
Water
41
If body temp falls below or goes above 37°C, | rates of chemical reactions are affected
Normal Body Temperature
42
Specific pressure of air is needed for adequate breathing and gas exchange in lungs
Appropriate atmospheric pressure
43
the maintenance of relatively stable internal conditions despite continuous changes in environment
Homeostasis
44
factors that can change (blood | sugar, body temperature, blood volume, etc.)
Variables
45
Monitors the environment and responds to stimuli
Receptors
46
Determines set point at which variable is maintained Receives input from receptor Determines appropriate response
Control center
47
Provides the means to respond Response either reduces stimulus (negative feedback) or enhances stimulus (positive feedback)
Effector
48
Variable changes in opposite | direction of initial change
Negative Feedback
49
Response enhances or exaggerates the | original stimulus
Positive Feedback
50
If negative feedback mechanisms become overwhelmed, destructive positive feedback mechanisms may take over
Disturbance of Homeostasis
51
Body erect, feet slightly apart, palms facing | forward with thumbs pointing away from body
Anatomical Position
52
Two major divisions of body : Head, neck, trunk
Axial
53
Two major divisions of body : Limbs
Appendicular
54
Divides body vertically into right and left parts
Sagittal Plane
55
``` Divides body vertically into anterior and posterior parts (front and back) ```
Frontal Plane
56
Divides body horizontally (90° to vertical plane) into superior and inferior parts (top and bottom)
Transverse Plane
57
Result of cuts at angle other than 90° to | vertical plane
Oblique Section
58
Protects fragile nervous system Two subdivisions
Dorsal Body Cavity
59
Encases brain
Cranial Cavity
60
Encases spinal cord
Vertebral Cavity
61
Houses the internal organs
Ventral Cavity
62
Houses the the pleural cavities, mediastinum, and the pericardial cavity
Thoracic Cavity
63
Cavity that surrounds the lung
Pleural Cavity
64
surrounds the pericardial cavity and the rest of the thoracic organs
Mediastinum
65
Encloses the heart
Pericardial Cavity
66
Thin, double-layered membranes that cover surfaces in ventral body cavity
Serosa
67
Pericardium
Heart
68
Pleurae
Lungs
