UIOWA | University of Iowa | UPDATED Questions with
100% Verified Answers
Q1: Physiology
A: Study of human function
Q2: Homeostasis
A: Maintaining a stable internal environment to support optimal function under given
circumstances
Q3: regulated variables of homeostasis
A: Blood pressure, pH, body temperature, blood sugar
Q4: Set point
A: value where we keep regulation in homeostasis
Q5: sensors (homeostasis)
A: detect changes in variables and relays to integrator
Q6: Integrator (homeostasis)
A: Makes decision what to do to regulate variables
Q7: effectors (homeostasis)
A: any organ or tissue that receives information from the integrating center and makes
appropriate adjustments to counter the change - MANY TIMES OPERATES BY FEEDBACK
LOOP
Q8: Negative feedback system
A: a process that results in a response that reverses the original stimulus
MOST COMMON TYPE OF PHYSIOLOGICAL RESPONSE.
Regulation around setpet
Q9: Positive feedback system
A: change in condition leads to a response that amplifies change.
push it even further away from the set point. This doesn't really happen for us
Q10: Antagonistic Effectors
A: Maintained by opposing effectors that move conditions in opposite directions
,Q11: feedforward control
A: The anticipation of stimuli, activates effectors in advance (think sprinter before race, body
starts to make changes to prepare for event)
Q12: levels of organization in the body
A: atomic
cell
tissue
organ
organ system
organism
Q13: Atomic/Molecular Level
A: all higher level functions are based upon the principles of physics and chemistry
Q14: cellular level of organization
A: basic unit of structure and function of living things
Q15: tissue level of organization
A: groups of similar cells that have a common function
Q16: organ level of organization
A: contains two or more types of tissues that form a structure with a specific function
Q17: organ system level of organization
A: Consist of different organs that work together closely to perform related functions
Q18: Organism level of organization
A: organ systems make up an organism
Q19: Four types of tissue
A: epithelial, connective, muscle, nervous
Q20: Muscle tissue
A: A body tissue that contracts or shortens, making body parts move.
Q21: types of muscle tissue
A: skeletal (MULTIPLE NUCELI) Cardiac (heart), smooth (organs)
Q22: Nervous tissue
, A: Cells designed to receive and transmit information through neurons
Some send out information
Q23: Afferent pathway
A: Pathway of receptor to control center
Q24: Efferent pathway
A: Pathway of control center to effector
Q25: Neurons
A: high speed communication via electrical signals
Q26: Neuroglia
A: cells that support and protect neurons
Q27: epithelial tissue
A: A body tissue that covers the surfaces of the body, inside and out
Q28: Functions of epithelial tissue
A: Regulate movement of materials
Absorb
Excrete
Barrier
Protection
Form EXOCRINE GLANDS
Q29: Connective tissue
A: A body tissue that provides support for the body and connects all of its parts
Function: connection, structure, support, transportation
unique structure
large amounts of extracellular matrix
Q30: Function of connective tissue
A: Connection, support, transportation (blood)
Q31: Unique structure of Connective tissue
A: large amounts of extracellular matrix
Q32: Types of connective tissue
A: Adipose
Large cells
