Flashcards in Test 1 Deck (51):
Study of the systems such as cardiovascular, respiratory, nervous, digestive systems
Study of the body by areas. Like head and neck, extremities, and abdomen.
Study of external features, such as bony projections, that help locate internal structures.
Uses special imaging, like (x-rays, MRIs, and ultrasounds) to create pictures of internal structures
The process and function of living things
Moving. Good for the body
Not moving. At rest.
Is the study of specific organisms within the human body.
Multiple chemicals together makes a cell
Multiple cells together makes a tissue.
Multiple tissues together makes an organ.
Multiple organs together makes an organ system.
Multiple organ systems together makes an organism.
"Little organ" of a cell.
Living material surrounding the nucleus
Contains many types of organelles
Contains DNA of the cell.
"Brain of cell" chromosomes
Endoplasmic Reticulum (ER)
Makes proteins and lipids.
Rough Endoplasmic Reticulum (ER)
Smooth Endoplasmic Reticulum (ER)
Collects, modifies, packages and distributes proteins and lipids that are manufactured by ER
Contents are released to the exterior of the cell
Study of the structure of the human body
ATP production. The "power house" of the cell
Homeo (same)- stasis(standing)
Maintaining the balance. Body trying to stay normal.
Is good! Homeostasis at work
Is bad. Body is becoming less healthy
0-14 scale. 0- Acidic, 14-Basic or Alkaline, 7-Neutral. Body wants to be neutral.
The 11 major Organ Systems
2.Skeletal 3.Muscular 4.Lymphatic 5.Respiratory 6.Digestive 7.Nervous 8.Endocrine(hormones) 9.Cardio 10.Urinary 11.Reproductive
pH > 7
14 most alkaline or basic
Ex: Sodium Hydroxide (NaOH)
pH at 7.0
Is in balance
Ex: Distilled water
Blood is 7.4
Types of Tissues and Tissue Systems
1.Epithelial 2.Connective 3.Muscle 4.Nervous
Epi - on or above
Thele - covering or lining
Fxn: protects underlying structures, secrete substances
1 layer. Thin
2 or more layers. Thicker and more protection.
The 3 Muscles we have
(aka mm fibers)
1. Skeletal, e:bicep brachii
2. Cardiac, e: heart mm
3. Smooth, e: hollow organs like digestive system
A substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction
Doesn't combine with or dissolve by water.
Having a tendency to mix with, dissolve in, or be wetted by water.
A carb whose molecules consist of a number of sugar molecules bonded together
Any of a class of sugars whose molecules contain 2 monosaccharide residues
Any of a class of sugars that cannot be hydrolyzed to give a simpler sugar
Connective Tissue (CT)
Material that separates cells. Fxn: Encloses and separates. Adipose tissue (fat) stores energy
(Skin) Lack of equals. Albino
The study and treatment of tumors.
Lowest layer of skin. Skin rests on this foundation.
Middle layer of skin. The majority of the skin is here, follicles and glands start here
