Bio 168 Exam 1

Exam 1 Chapters 1,2 and Half of 3

QuestionAnswer
_______ studies the STRUCTURE of body parts and their relationships to one another. Anatomy
_______ concerns the FUNCTION of the body, in other words, how the body parts work and carry out their life-sustaining activities. Physiology
Gross, macroscopic, regional, systemic, surface, microscopic, and developmental anatomy are all topics under Anatomy OR Physiology? Anatomy
Renal, neurophysiology, and cardiovascular are topics under Anatomy or Physiology? Physiology
"Although it is possible to study anatomy and physiology individually, they are really inseparable because function always reflects structure." This is key concept is called what? Principle of Complementarity of Structure and Function
The Six levels of organization? Chemical=>Cellular=>Tissue=>Organ=> Organ System=>Organism
Name the 11 Body Systems Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic, Respiratory, Digestive, Urinary, Male Reproductive, Female Reproductive.
Body covering or Skin, protects deeper tissues from injury. Integumentary
Protects and supports body organs, provides a framework the muscles use to cause movement. Skeletal
Main Function of Integumentary System Barrier
Main function of Skeletal System Framework
Main Function of Muscular System Movement
Main Function of Nervous System Rapid Communication
Main Function of Endocrine System Slow Communication
Main Function of Cardiovascular System Transport
Main Function of Lymphatic System Immunity
Main Function of Respiratory System Gas Exchange
Main Function of Digestive System Obtain Nutrients
Main Function of Urinary System Excrete Fluid Waste
Main Function of Reproductive System New Offspring
Why study Anatomy and Physiology together? Because function always reflects structure
8 Characteristics of Life Maintain Boundaries, Metabolism (All the chemical reactions in the body), Growth, Respond to Stimuli, Reproduction, Digestion= Obtain small molecules, Excretion=Feces, urine, exhale, sweat, Movement= External, Internal
5 External Environmental requirements to sustain life Oxygen, Water, Nutrients, Temperature, Pressure (Air pressure)
______ is the ability to maintain relatively stable internal conditions even though the outside changes continuously. Homeostasis
What does feedback control?
What is Anatomical Position? Erect, facing forward, arms at side, feet slightly apart, palms forward
This plane vertically divides the body into anterior and posterior parts Frontal/Coronal Planes
This plane divides the body into left and right parts Sagittal/Median Plane
This plane divides the body into EQUAL left and right parts. Midsagittal
This plane horizontally divides the body into Superior and Inferior parts Transverse Plane
What are the two major Body Cavities? Dorsal and Ventral Body Cavities
Which body cavity contains the brain? Cranial
Which body cavity contains the spinal cord? Vertebral or Spinal Cavity
Which body cavity contains the heart and the lungs? Thoracic
Which Pleural Cavities contain what? Lungs
The Pericardial Cavity contains what? Heart
The Thoracic cavity is separated from the abdominopelvic cavity by what dome shaped muscle important in breathing? Diaphragm
This Cavity contains the stomach, liver, intestines, spleen and other organs Abdominal Cavity
The Pelvic Cavity includes? Urinary bladder, some reproductive organs and the rectum
What organs are found in the Right Hypochondriac region? Liver, Gallbladder
What organs are found in the Right Lumbar region? Ascending Colon
What organs are found in the Right Iliac (Inguinal Region)? Cecum, Appendix
What organs are found in the Epigastric Region? Stomach
What organs are found in the Umbilical Region? Small Intestine, Transverse Colon
What organs are found in the Hypogastric Region? Urinary Bladder
What organs are found in the Left Hypochondriac Region? Diaphragm, Spleen
What organs are found in the Left Lumbar Region? Descending Colon of the large intestine
What organs are found in the Left Iliac (inguinal) Region? Initial part of sigmoid colon
Name five techniques for imaging structures of the body without surgery... X-ray, CT, MRI, PET Scan, Ultrasound
This technique for imaging structures uses radiation energy that has the ability to penetrate through soft tissues, huge risk to gonads if proper precautions aren't take... X-rays
Takes X-ray's from multiple angles and a computer puts it together for a 3-dimentional view. Allows for better soft tissue views. CT Scan (Computerized Tomography)
Uses a very strong magnetic field to cause water molecules to spin, which creates an energy. Converts relative amounts of water in tissues. The more color shown, the more energy. MRI (Magnetic Resonance Imaging)
Uses some type of radioactive dye, which releases energy, focuses on specific organs. PET (Positron Emission Tomography)
Uses sound waves that go through soft tissues and really soft tissues that bounce off a baby and comes back and a computer puts the image together Ultrasound
Chemistry is the study of.... Matter and all of the changes it undergoes
Define Matter and the 3 states that it exists in? Any solid, liquids or gases
Define Energy The capacity to do work
What forms can energy have? Electrical, Chemical, Mechanical, Thermal, Solar
What is Active Energy? Kinetic Energy
What is Potential Energy? Stored Energy
What elements are in the body? 27
How many elements are there? 112
Names and symbols for 4 major elements make up 96% of the body.... Carbon, Hydrogen, Oxygen, Nitrogen
Names and symbols of 9 minor elements.... Calcium, Phosphorus, Potassium, Sulfur, Sodium, Chlorine, Magnesium, Iodine, Iron
Names and symbols of 4 Trace elements.... Manganese, Chromium, Zinc, Silicon, Tin, Fluorine, Copper, Cobalt, Molybdenum, Selenium, Vanadium
What are the 3 Subatomic Elements?
What is an isotope?
How are radioactive isotopes uses medically?
What is a molecule?
What is a compound?
What is a mixture?
Difference between Solution, a Colloid and a suspension
How is the blood a combination of solution, colloid and a suspension
What do protons and neutrons do for an atom?
What do electrons do for an atom?
How many electrons in the outer energy level will make an atom "stable"?
What atoms form ionic bonds?
