25
respiratory body function
assists with gas exchange; keeps blood supplied with oxygen and removes dioxide
26
respiratory body function key structures
nasal cavity, lungs, trachea, bronchus
27
lymphatic body function
secretes hormones that regulate processes such as growth, reproduction, and metabolism by body cells
28
lymphatic body function key structures
bone marrow, thymus, spleen, lymph nodes
29
urinary body function
eliminates waste and regulates water balance of blood
30
urinary body function key structures
kidney, bladder, urethra, urether
31
digestive body function
breaks down food into its nutrients molecules; absorbs nutrients
32
digestive body function key structures
oral cavity, stomach, large and small intestine, esophogas
33
skeletal body function
protects and supports body organs; provides a framework the muscles use to cause movement
34
skeletal body function key structures
bones and joints
35
algor mortis
body begins cooling/heating process to match the surrounding temp and it starts immediately after death until 24 hours
36
rigor mortis
stiffness in the joints first in the head and then the neck and begins 2-4 hours after death and then fades 36-48 hours
37
livor mortis
blood pooling when blood settles or collects on parts of body on floor and starts within 2 hours
38
corneal clouding
corneas of the eyes become milky or cloudy within the first few hours of death
39
decomposition
body turns green and may swell/bloat as bacteria breakdown tissue and releases gas
40
insect activity
can provide clues as to how long a person has been deceased. eggs, larva, or full grown bugs provide time stamp and starts within 1-145 hours
41
glastier equation
(98.4 - rectal temp)/1.5 = approx hours since death
42
ambient temp
air temp of surroundings
43
how does ambient temp affect rate of cooling
if the temp is cold, the body cools faster, if its hot, the body heats up faster
44
toxin vs toxicant
toxin - poison produced by a living organism toxicant - manmade, harmful substance
45
nutrient vs molecule
nutrient - substance body needs to maintain health molecule - group of atoms held together by chemical bonds
46
metabolism vs digestion
digestion - process of breaking down food into nutrients and molecules metabolism - chemical reaction process to build more complex molecules
47
chemical reaction
process where atoms and/or molecules are rearranged to transform matter
48
order of digestive system
1- oral cavity 2 - esophogas 3 - stomach 4 - small intestine 5 - large intestine
49
presumptive test
quick tests that indicate if a type of substance is presented but cannot specifically identify a substance
50
confirmatory test
specific tests that can determine the exact identity and composition of a substance by pinpointing certain properties of that substance
51
negative vs positive control
negative - variable being experimented on positive - answer key basically
52
histology
study the microscopic structure of tissues
53
largest to smallest
organ system organ tissue cell
54
central nervous system (cns)
the brain processes info, makes decisions about what to do, and sends signals back using peripheral system to bring about a specific change (also uses spinal cord think CENTRAL nervous system uses spinal CHORD)
55
peripheral nervous system (pns)
nerves bring info from outside and within the body to the cns for processing
56
temporal lobe
used for processing language and storing info in long-term memory (the bottom of the brain)
57
parietal lobe
crucial in integrating sensory ad visual info (the top right of the brain)
58
occipital lobe
recieves and processes sensory nerve impulses from eyes (below the parietal lobe)
59
frontal lobe
responsible for planning and organizing incoming info and controls behavior and emotions (top left of brain think when you're reading you read from the left aka front of the paragraph)
60
nervous tissue
found in the spinal cord and brain made up of neurons that work to receive, interpret, and respond to signals
61
epithelial tissue
found lining outer surfaces organs/blood vessels/humans, works to absorb secrete, protect and sense
62
muscle tissue
found attatched to bones in the walls of organs or walls of heart and provides ability to contract
63
connective tissue
supports/connects other tussye types in the body, holds organs in place, attaching muscles to bones, and links bones with joints
64
tricuspid valve
between the RA and RV
65
pulmonary valve
between RV and pulmonary artery
66
mitral/bicuspid valve
between LV and LA
67
aortic valve
between LV and aorta
68
superior vena cava
sends blood TO HEART, recieves blood from top half of body, and gives blood to RA
69
inferior vena cava
sends blood TO HEART, recieves blood from lower half of body, and gives blood to RA
70
pulmonary artery
sends blood AWAY FROM HEART, recieves blood from RV, gives blood to lungs
71
pulmonary viens
sends blood TO HEART, recieves blood from lungs, and then gives it to LA
72
aorta
sends blood AWAY FROM HEART, recieves blood from LV and then sends it to body
73
coronary arteries
sends blood TO HEART, recieves from LV and then gives it to the heart
