Anatomy Flashcards
Anatomy
the study of the structure and shape on the body and its parts and their relationships
Physiology
the study of how the body and its part work or function
What is the level of structure of organization?
Atoms, Molecules, Cells, Tissues, Organs, Organ Systems
Atoms
tiny building block of matter (Oxygen, Hydrogen, Sodium)
Molecules
atoms come together to form ___ (Water, Sugar, and Proteins)
Cells
molecules combined form___. smallest living thing. common structures and functions, but individual ones vary in size shape, and role (Red Blood, White Blood, bone, skin)
Tissues
Cells come together to form ____. groups of similar cells which work together to perform a common goal or function
4 main types of tissue
Epithelial, Connective, muscle, and nervous
Epithelial
cover the body and organs, protecting and separating the body for its environment. (Think SKIN)
Connective
binds, connects, and cushions the body (think BONES)
Muscle
allow for contraction and movement
Nervous
allows for communication by transmitting electrical pulses
Organs
a collection of tissues that structurally form a functional unit specialized to perform a particular function (Think LUNGS, LIVER, HEART)
Organ Systems
a group of anatomical structures in the body that work together to perform various functions
Homeostasis
a self-regulating process that living systems maintain in their internal physical and chemical conditions by adapting to survive in changing environments
How many Organ Systems are there? What are they?
11; Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic, Respiratory, Digestive, Urinary, and Reproductive
Two examples of homeostasis explained:
- Body temp: if your body temp is too hot, blood vessels will dilate making you sweat to cool you down. If your body temp is too cold, they will constrict to help you retain body heat causing “goose bumps”
2.Blood sugar: keeps blood sugar regulated based on internal conditions like the amount of carb intake
What are the 3 main components of homeostasis?
receptor, control center, and effector
What are the 4 categories of organ systems based on their function?
- support, movement, and protection
- integration and condition
- maintenance of the body
- reproduction and development
Integumentary system organs
skin and accessory organs (nails and hair) skin is the largest organ
Integumentary system function
protects tissue, regulates body temp, and contains sensory organs
What category is the Integumentary System
support movement and protection

Skeletal System organs
bones, cartilage and ligaments. 206 bones
