PRINCIPLES OF ANATOMY AND PHYSIOLOGY
EXAM 2 ACTUAL PAPER 2026 COMPLETE
QUESTIONS SOLUTIONS GRADED A+
◉ Physiology.
Answer: science of how body functions-how the body works
◉ How many levels of structural organization.
Answer: 6
◉ How many body systems.
Answer: 11
◉ Chemical level.
Answer: atoms>molecules(DNA)
◉ Cellular level.
Answer: Smallest structural/functional units of organisms and the
smallest living units in the body ex. nerve, muscle, epithelial
◉ Tissue level.
,Answer: groups of cells & materials surrounding them working
together for a particular function
4 basic types:
1. epithelial
2. connective
3. muscular
4. nervous
◉ Epithelial Tissue.
Answer: covers body surfaces, lines inside of organs, forms glands
◉ Connective tissue.
Answer: support, connects, and protects organs
◉ Muscular Tissue.
Answer: generates a force through contraction and relexation
◉ Nervous Tissue.
Answer: Transmit electrical impulses
◉ Organ level.
, Answer: (paragraphs) diff types of tissues are joined together to
make organs= structures composed of 2 or more diff types of
tissues; have specific functions and usually recognizable shapes ex)
stomach, skin, heart, lungs
◉ System level.
Answer: consists of related organs with a common function
**sometimes an organ can be a part of more than 1 system
◉ Organism level.
Answer: organism: any living individual
all parts of the human body functioning together constitute the total
organism
◉ Integumentary System.
Answer: Components:Skin, Hair, Nails, Sweat and Oil Glands
Function: protects body, helps regulate body temperature,
eliminates some wastes, helps make vitamin D, detects sensations
such as touch, pain, warmth, and cold, stores fat and provides
information
◉ Skeletal system.
Answer: Function: supports and protects body, muscle attachments,
aids body movement
