25
What are the five environmental factors?
WAter, Food, Heat, Pressure, Oxygen
26
Water
most abundant substance in body. environment for metabolic processes. required for transport of substances. regulation of body temperature.
27
Food
provides necessary nutrients. supplies energy. supplies raw materials for building living tissue.
28
Oxygen
one-fifth of air. | used to release energy from nutrients.
29
Heat
heat is a form of energy in our environment. helps maintain body temperature. partly controls rate of metabolic reactions.
30
Pressure
application of force on an object. atmospheric pressure – important for breathing. hydrostatic pressure – keeps blood flowing.
31
Homeostasis
Maintenance of a stable internal environment
32
Homeostatic Mechanisms
Self-regulating systems that monitor aspects of the internal environment and correct them as needed
33
Receptor
detects and provides information about the stimuli
34
Control Center
: decision-maker that maintains the set point
35
Effector
muscle or gland that responds to the control center, and causes the necessary change in the internal environment
36
Three parts of the homeostatic mechanicms?
Receptor, Control Center, Effector
37
Negtive Feedback
Most common type of homeostatic mechanic. Return condiitons toward normal range Negative because the response to the change moves the variable in the opposite direction
38
Positive Feedback
Uncommon in the body Change is intensified Produce unstable condiitons Examples: Blood Clotting, And the Uterine Contractions of Childbirth
39
Two major portions of the body?
Axial and Appendicular Potion
40
Axial Portion
Head, Trunk, Neck
41
Appendicular Portion
Upper and lwoer limbs
42
Cranial Cavity
Houses Brain
43
Vertebral Canal
COntains spinal corrd
44
Thoracic Cavity
Houses lung and thoracic viscera
45
Abdominopelvic Cavity
Contains abdominal and Pelvic viscera
46
Diaphragm
Muscle that separates the thoracic and abdominopelvic cavities
47
Meiastinum
Region between lungs in thoracic cavity, which contains heart, esophagus, trachea, thymus gland
48
Abdominopelvic cavity contains 2 portions
Abdominal cavity and pelvic cavity
49
Abdominal Cavity
extends from diaphragm to top of pelvis, and contains stomach, liver, spleen, kidneys small intestine, most of large intestine
50
Pelvic Cavity
enclosed by pelvic bones, and contains end of large intestine, urinary bladder, internal reproductive organs
51
Small cavities in the head
oral, nasal, orbital, and middle ear cavities
52
thoracic and abdominopelvic cavities are lined by...
double-layered serous membrane, which secrete serous fluid
53
Serous membrane consists of 2 layers
Visceral layer and parietal layer
54
Visceral layer
inner layer, covers an organ
55
Partietal layer
outler layer, which lines wall of cavity
56
Integumentary System
Protection, body temperature regulation, sensory reception, production of Vitamin D
57
Skeletal System
Framework, protection, attachment sites, storage of inorganic salts, production of blood cells, support and movement
58
Muscular System
Movement, main source of body heat, maintenance of posture.
59
Nervous and Endocrine System
Integration and coordination of organ function through nerve impulses or hormones
60
Cardiovascular System
Transportation of gases, nutrients, blood cells and wastes
61
Lymphatic System
Transportation of fluids, lymphocyte production, body defense
62
Cardiovascular System
Transportation of gases, nutrients, blood cells and wastes
63
Lymphatic System
Transportation of fluids, lymphocyte production, body defense
64
