|
Anatomy |
The science of structure and the relationships among structures |
|
|
Physiology |
The science of body functions, Structure of a part determines how it will function The COMPLEMENTARY of Structure and Function. |
|
|
Histology |
The science of the microscopic structure of biological material Ways in which individual components are structurally and functionally related. |
|
|
4 catagories of food molecule |
lipids, carbohydrates, proteins, nucleic acid |
|
|
6 levels of body organization |
Chemical Cellular Tissue Organ Organ system Organism |
|
|
Parts of chemical level |
Subatomic: neutrons, protons, electrons. Atomic: hydrogen, oxygen Molecules: water/glucose (bonded atoms) Macromolecules: DNA, proteins |
|
|
Cellular level |
basic structural and functional unit of an organism Smallest living unit in the body. Contain organelles |
|
|
Basic cell functions |
→ reproduction→ obtain nutrients+ Oxygen→ cellular respiration→ eliminate carbon dioxide and other waste→ synthesize cellular components→ review slide |
|
|
4 types of tissue |
Epithelial, connective, muscular, nervous |
|
|
Emergent properties |
Ex) cells come together to form tissues Arise due to the ARRANGEMENT AND INTERACTIONS of parts |
|
|
When do body structures emerge |
Embryological devel |
|
|
Life processes |
Metabolism, responsiveness, movement, respiration, digestion, absorption, assimilation, circulation, excretion, growth, differentiation, reproduction |
|
|
What is metabolism? |
→ chemical reactions in body→ making body structures |
|
|
Responsiveness |
→ respond to internal and external environments→ sense+ react to Change |
|
|
movement |
→ motion of whole body, individual organs, single cells, intracellular Structures |
|
|
Respiration |
→ obtain oxygen remove CO2 release energy from food |
|
|
Digestion |
→ breakdown and delivery of nutrients |
|
|
Absorbtion |
→ passage of Substance through membranes into bodily fluid |
|
|
assimilation |
→ Changing of absorbed substances into chemically different forms |
|
|
Circulation |
→ Movement of substances in body fluids |
|
|
Excretion |
→ Elimination of waste from metabolic reactions. |
|
|
Growth |
→ Increase in size and numbers of cells and intracellular structures |
|
|
Differentiation |
→ Process whereby unspecialized cells become specialized. |
|
|
Reproduction |
→ Formation of new cells for growth, repair, replacement, or production of a new individual → Production of future generation |
|
|
Homeostasis |
Conditions in which body's controlled internal environment acts to remain a steady state despite Changes inside and outside the body |
|
|
Extracellular fluid |
Fluid outside cells (plasma and interstitial fluid) |
|
|
Homeostatically regulated factors |
→ Concentration of nutrient molecules → Concentration of O2 and CO2→ Concentration of waste products → pH (acid levels) → Concentration of water, salt, and other electrolytes → Volume and pressure → Temperature |
