REVIEW WITH VERIFIED AND
ACCURATE ANSWERS GRADED
A+ (2026)
Anatomy - answer-Study of the structures of the body and the relationships between
them
Physiology - answer-Study of the functions of the body parts(how they work)
Levels of Organization - answer-Atom
Molecule
Macromolecule
Organelle
Cell
Tissue
Organ
Organ system
Organism
Organ systems - answer-Ex.) nervous, digestive, urinary, respiratory
Organs - answer-Ex.) lungs, heart, pancreus, liver
Tissue(histology) - answer-Ex.) muscle, nervous, epithelial, connective
Cellular(cytology) - answer--Cells are the basic unit of life
-organisms cannot havelige until they reach the cellular level
,-sinlge or multicellular
Homeostasis - answer-The bodys attempt to maimtain a constant evironment despite
internal anf external disruptions
Ex.) tempurature, blood sugar, PH
Stress - answer-Any disturbance that causes an inbalance within the normally
acceptable ranges of homeostasis(physical, chemical or emotional)
2 main systems involved in homeostasis - answer-Nervous and endocrine(ex.
Hormones)
Feedback loops - answer-Keep the body informed of any changes that may be occuring
and also help to return the body to homeostasis
Factors in Feedback loop - answer--Receptor
-Control center(brain)
-Effector
-Controlled Condition(body temp)
Negative Feedback loop - answer--more common
-IMMEDIATE REVERSAL
-restore homeostasis
-ex. Sweat/chill, standing up after getting out of bed(lower bp)
Example negative feedback loop - answer-1.)baroreceptor(located in arteries)
2.) hypothalamous
3.) heart rate decrease
4.) blood pressure (110/70-120/80)
, Positive feedback loop - answer--less common
-INTENSIFIES ESCALATES
-ex. Labor
Example positive feedback loop - answer-1.) activates strech receptors in the cervix
2.) pituitary
3.) oxytocin(hormone)
4.) uterus---contractions
Integumentary (skin) - answer-Protection, senses, temperature regulation
Muscular system - answer-Movement, heat production
Skeletal system - answer-Protection, support, mineral storage
Nervous system - answer-Controls body activity, regulates metabolism, thoughts
Endocrine system - answer-Maintains homeostasis with the use of hormones
Immune/lymphatic system - answer-Body's defense against infection, recycling of
interstitial fluid, blood cell production
Circulatory system - answer-Carries oxygen and nutrients to body cells
Respiratory system - answer-Gas exchange, regulation of pH
Digestive system - answer-Breaks down food and absorbs nutrients
