BIO 210 LECTURE EXAM 1 / STUDY GUIDE ACTUAL EXAM / 170+ QUESTIONS & COMPLETE ANSWERS / ALREADY GRADED A+ / 2025. Physiology examines living organisms and their parts of how they function Microscopic anatomy examines structures that cannot be observed by the unaided eye Two main subdivisions of microscopic anatomy cytology and histology cytology study of cells Histology study of tissues Gross anatomy or macroscopic anatomy investigates the structure visible to the aided eye Systematic anatomy each individual body system Regional anatomy all the structures in a particular region of the body Surface anatomy focuses on superficial anatomic markings and internal body structures Comparative anatomy examines similarities and differences in the anatomy of different species Embryology studies developmental changes from conception to birth Pathologic anatomy examines anatomic changes resulting from disease Radiographic anatomy investigates internal structures with visual scanning procedures Physiology examines living organisms and their parts of how they function Cardiovascular physiology the functioning of the heart, blood vessels and blood Neurophysiology functioning of the nerves and nervous system organs Pathophysiology relationship between the function of an organ system and disease of injury of the system Respiratory physiology functioning of respiratory organs Reproductive physiology the functioning of the hormones and reproductive cycle Homeostasis the body's ability to maintain a stable internal environment Receptor component of homeostasis that the structure that detects changes in the stimulus, sensory nerves Stimulus component of homeostasis that changes in a variable that is regulated Control center component of homeostasis that processes the change that occurred from the receptor Negative feedback if it is high, lower it. If it is low, raise it. Negative because the response is opposite of the stimulus Set point variable maintained within a normal level The hypothalamus part of the brain that regulates body temperature Positive feedback moves the stimulus in the same direction, occurs less frequently than negative feedback
