What basic life process is illustrated by this description - answermovement The homeostasis of the body is controlled through a series of steps called a feedback system or feedback loop. One component of such systems is a control center. Which of the following organs would frequently serve as the control center for a feedback system (remember, the control center evaluates the disruption to homeostasis, and it also triggers a response) - answerbrain Regulation of blood glucose in the body is an example of - answerhomeostasis dissection of organs examination of tissues with a microscope investigating the chambers of the heart identifying the features of the bones of the arm ... examples of studying anatomy or physiology? - answeranatomy Homeostasis is the condition in which the body maintains - answera relatively stable environment within limits Place the following in correct sequence from the simplest to the most complex: 1. tissue 2. organismal 3. organ 4. chemical 5. system 6. cellular - answer4,6,1,3,5,2 The lowest level that exhibits the characteristics of life is - answercells This system produces body movements, stabilizes body positions and generates heat - answermuscular The two systems most responsible for maintaining homeostasis are the - answerendocrine and nervous A particular stimulus causes an increase in the levels of CO2 in the blood. A feedback mechanism that increases respiration rate to exhale more CO2 would be - answerpositive what is a positive feedback mechanism - answera feedback mechanism that reinforces the change in the controlled condition In order to improve a patient's _______, a respiratory therapist would be interested in studying the functions of the individual's ___________ - answerbreathing, air passageway and lungs At what level(s) of organization would an exercise physiologist study the human body - answercell, organ, organ system Monitors the changes in a controlled condition and sends input to a controlled center - answerreceptor Receives input from a receptor and analyzes it - answercontrol center Which describes the study of the functions of body structures - answerphysiology Hormonal or electrical signals are sent from the control center to the - answereffectors If blood concentrations of thyroid hormones increase above a certain level, Thyrotropin- releasing hormone (TRH) neurons in the hypothalamus are inhibited and stop secreting TRH. This is an example of - answernegative feedback Which subspecialty of physiology deals with the effects of hormones control of reproduction - answerendocrinology If one was reviewing the pattern of tissue changes associated with disease development, they would be studying - answerpathological anatomy If a doctor listens to a gurgling noise within the gastrointestinal tract, they are performing - answerauscultation _____ occurs when an embryonic stem cell becomes a neuron - answerdifferentiation Hydrochloric acid and pepsin are enzymes secreted by cells in your stomach to digest proteins. The presence of partially digested protein in the stomach triggers the secretion of more HCl and pepsin. Thus, once digestion begins, it becomes a self-accelerating process. This is an example of - answerpositive feedback The cytoplasm of a cell is made up of which of the following - answerthe cytosol and organelles In what part of a cell would you find most of a cell's genetic material - answernucleus Which membrane proteins are involved with the transport of molecules that otherwise would be unable to enter the cell - answercarrier proteins Sodium-potassium pumps are examples of what type of cellular transport - answerprimary active transport What type of endocytosis allows cells to "drink" (take up tiny droplets of extracellular fluid) - answerpinocytosis Which of the following organelles plays an important role in phagocytosis (a type of endocytosis), contains a variety of digestive enzymes, and has transport pumps that maintain an acidic pH inside the organelle - answermitochondria The nucleus of a cell contains one or more of these structures that are the site of production of ribosomes - answernucleolus During the translation phase of protein synthesis, where would you find an anticodon - answeron the strand of rRNA In somatic cell division, a cell undergoes a nuclear division called ____, and a division of its cytoplasm called _____ - answermitosis and cytokinesis Sister chromatids of a pair of homologous chromosomes form tetrads, and crossing-over (exchange of genetic information between regions of non-sister chromatids in the tetrad) occurs during which phase - answermitotic prophase 1
