Anatomy and Physiology 1
Question | Answer |
---|---|
Define Anatomy | the study of body parts |
Define Physiology | the study of functions of body parts |
Examples of specific fields | Systemic anatomy and physiology |
Levels of organization | chemical (atoms and molecules) cellular (cells and their organelles) tissue (group of similar cells) organ (group of 2 types of tissue) organ system ( 2 or more organs working together) |
Importance of anatomic position | It is position of reference |
Identify 3 body planes | transverse, sagittal and coronal |
Upper right quadrant | kidney, most of liver and gal bladder |
Upper left quadrant | kidney, stomach and spleen |
Lower right quadrant | 1/2 bladder and appendix |
Lower left quadrant | 1/2 bladder |
Types of Serosal membranes and where | visceral (inner layer) parietal (outer layer) |
Define Homeostasis | ability to maintain a consistent inner environment in response to changing conditions. |
Receptor | sensor |
Control Center | ability to determine set point in which variable is maintained |
Effector | response act to reduce or enhance feedback |
Set Point | the ideal normal value for a variable |
Define negative and positive feedback | positive feedback amplifies the stimulus in same direction while negative feedback regulates most body process and moves stimulus in opposite direction |
Characteristics common to all living things (first 3) | organization (perform specific functions) development (changes organisms go through) metabolism (sum of all chemical reactions) |
Integumentary system | skin ; provides protective barrier |
Nervous system | brain ; controls cell function |
Reproductive system | vagina ; produces gametes |
Respiratory system | lungs ; adds oxygen to blood and removes carbon dioxide |
Skeletal system | bones ; protects major organs |
Muscular system | cardiac muscle ; moves bones |
Characteristics common to living things (second 3) | regulation (responses to stimuli regulate body functions) responsiveness (ability to sense and react to stimuli) reproduction (production of new cells) |
Urinary system | Kidneys ; removes waste |
Cardiovascular system | heart ; transports nutrients |
Digestive system | stomach ; breaks down food so body can absorb |
Endocrine | pancreas ; control cell functions with hormones (homeostasis) |
Lymphatic | thymus ; filters and detects diseases |
