Checklist for Lecture Exam 1 Chapter 1 ANATOMY : The study of structure PHYSIOLOGY: The study of function. Levels of organization CHEMICAL LEVEL: includes Atoms ( C‚O‚ H‚ N)‚ the smallest units of matter. These 4 are essential to life. Atoms bond together to form MOLECULES. CELLULAR LEVEL: Molecules combine to form Organelles. Organelles function together to form a CELL‚ the smallest unit of life. There are different types of cells with different functions. A cell consists of

A) Joseph has many risk factors‚ one of them including his family has a history of vascular disease‚ and he had not thought much about it because he was not living a healthy life style. He had gained weight from eating fatty foods‚ and had started smoking again. Joseph had a lot of stress from working long hours‚ and did nothing when he had felt tightness in his chest. These risk factors all affect cellular function. The blood slows‚ along with oxygen‚ glucose‚ and essential ions it carries that

Dark amber urine‚ dry mucus membranes‚ poor skin turgor‚ and labs all point in that direction. Although the patient’s output seems to be adequate‚ everything else points towards dehydration. It also seems like the patient has a fluid/electrolyte imbalance which may be putting the water in the wrong departments‚ or an infection (as reflected in pt. vital signs). So even though he is receiving IV fluids‚ it’s not reflecting on his physical assessment and labs. 2.) What factors could be contributing

the information to the control center. The control center then receives the information from the sensor and compares it to the correct set value. It then signals the effector if necessary. The effector then takes necessary action to correct the imbalance based on the information the control center sends it. An example of negative feedback would be body temperature. The controlled variable is your core temperature‚ which is the temperature in the center of your body. The temperature sensors in your

reflexive behaviors that are elicited when certain stimuli are present. 2. Homeostatic Theories The assumptions of the homeostatic theory are that organisms attempt to maintain homeostasis‚ the balance of physiological state or equilibrium‚ by constantly adjusting themselves to the demands of the environment. It can be noted that every living thing has certain biological needs‚ sex‚ hunger‚ thirst‚ that is caused by imbalance because those variables are absent in the physical body. 3. Arousal Theory
