Explain the difference between the study of anatomy and the study of physiology. -
(ANSWER)Anatomy is the study of the structures or morphology of body parts while
physiology is the study of the function of body parts
_&*
+_%
Name and define the levels of organization of life. - (ANSWER)1. Subatomic particles -
@#$%^&*(o(*&^%$
Atoms are composed of these small particles. Ex: electrons, ^&*( protons and neutrons.
)
2. Atoms - Chemicals consist of tiny particles. Ex: Hyrdrogen and Lithium.
3. Molecule - Atoms join together to form this. Ex: water, glucose.
4. Macromolecule - Molecules combine to form this. Ex: Protein molecule, DNA molecule.
5. Organelle - structures that carry on specific activities. Ex: protein, carbohydrates, lipids,
and nucleic acids, mitochondria, golgi apparatus, nucleus.
6. Cell - The basic unit of structure and function. Ex: Muscle cell, nerve cell.
7. Tissue - Specialized cells assemble into layers or masses that have special functions
and form this. Ex: simple squamous epithelium, loose connective tissue.
8. Organ - Groups of different tissues form organs which are complex structures with
specialized functions. Ex: skin, femur, heart, kidney.
9. Organ system - Groups of organs that function closely together form this. Ex:
integumentary, skeletal, digestive.
10. Organism - Interacting organ systems form this. Ex: Human.
Define metabolism. - (ANSWER)All of the chemical reactions in an organism that support
life.
Define homeostasis. - (ANSWER)Maintaining of a stable internal environment.
How does homeostatic mechanism maintain homeostasis? - (ANSWER)Homeostatic
mechanisms monitor the aspects of the internal environment and correct as needed.
Variations are within limits.
What is meant by negative feedback? - (ANSWER)"The deviation from the set point is
corrected (moves in the opposite or negative direction) and because the correction
reduced the action of the effectors."
How does negative feedback affect homeostatic mechanism? - (ANSWER)1. Prevents
sudden, severe changes in the body
2. Corrects the set point
3. Causes opposite of bodily disruption to occur, i.e. the 'negative'
