ANAT & PHYS I: FINAL EXAM
Question | Answer |
---|---|
the study of the structure of body parts and their relationships to one another | Anatomy |
the study of the function of the body | Physiology |
study of tissues | HISTOLOGY |
Levels of Structural Organization | Chemical,cellular,tissue,organ,organ system, organism |
Composed of the skin, sweatglands, oil glands, hair, andnails Protects deep tissues frominjury and synthesizes vitamin D | Integumentary System |
Site of blood cell formation,Stores minerals | Skeletal System |
Maintains posture,produces heat, Allows manipulation of the environment, locomotion, and facial expression. | Muscular System |
Responds to stimuli by activating muscles and glands, Is the fast-acting controlsystem of the body. | Nervous system |
Composed of red bone marrow,thymus, spleen, lymph nodes,and lymphatic vessels. Picks up fluid leaked from blood vessels and returns it to blood. | Lymphatic System |
Composed of kidneys, ureters,urinary bladder, and urethra. Regulates water, electrolyte,and pH balance of the blood. | Urinary system |
ability to maintain a relatively stableinternal environment in an ever-changing outside world | Homeostasis |
system where the output shuts offthe original stimulus Example: Regulation of room temperature | negative feedback |
system where the output enhances or exaggerates the original stimulusExample: Regulation of blood clotting | positive feedback |
toward and away from the head, respectively | Superior and inferior |
away from the midline | lateral |
cuts made diagonally | Oblique section |
divides the body into anterior and posterior parts | Frontal or coronal |
Ventral cavity houses the internal organs (viscera),and is divided into two subdivisions | Thoracic,Abdominopelvic |
Thoracic cavity is subdivided into two pleural cavities | the mediastinum,and pericardial |
contains the pericardial cavity;surrounds the remaining thoracic organs | mediastinum |
unique substances that cannot be broken down by ordinary chemical means | elements |
The nucleus consists of | neutrons and protons |
equal to the number of protons | Atomic number |
average of the mass numbers of all isotopes | Atomic weight |
atoms with same number of protons but a different number of neutrons | Isotope |
two or more different kinds of atoms chemically bonded together | Compound |
two or more components physically intermixed (not chemically bonded) | Mixtures |
homogeneous mixtures of components | Solutions |
No chemical bonding takes place in | mixtures |
All compounds are | homogeneous |
Compounds cannot be separated by | physical means |
Properties of Water: is an important part of hydrolysis anddehydration synthesis reactions | reactivity |
Contain carbon, hydrogen, and oxygen. Their major function is to supply a source ofcellular food | Carbohydrates |
Examples: Neutral fats, Phospholipids, steroidsEicosanoids | LIPIDS |
modified triglycerides with twofatty acid groups and a phosphorus group | Phospholipids |
Macromolecules composed of combinations of 20types of amino acids bound together with peptide bonds | PROTEINS |
release H+ and are therefore proton donors | Acids |
release OH– and are proton acceptors | bases |
Reversible unfolding of proteins due to drops in | PH ,increased temperature |
Body coverings: skin,Body linings: serous membrane,Glandular tissue: tonsils | Epithelial Tissues |
Epithelial Tissues Functions: | Protection, Absorption, filtration, Secretion |
Cartilage, Bone, blood | Connective Tissue |
Functions of Connective Tissue | Binding and support, Protection, insulationTransportation |
Functions of the: Metabolic functions – synthesis of vitamin D indermal blood vessels, Protection – chemical, physical, and mechanical barrier | Integumentary System |
Cells undergo rapid division (mitosis), hence its alternate name, stratum germinativum | Stratum Basale, Basal Layer |
Least malignant and most common skin cancer | Basal Cell Carcinoma |
Estimates the severity of burns | Rule of Nines |
Rule of Nines: There are third-degree burns on | face, hands, or feet |
Rule of Nines: Over 25% of the body has | second-degree burns |
Rule of Nines: | Over 10% of the body has third-degree burns |
