Human Body Structure Flashcards
Physiology
How the parts work
Anatomy
Structure of the body parts and thier location
What are the five levels of structural organization
Cells, tissues, organs ,body systems , and organism
what are the five functions of the cell
To take in food or oxygen, produce heat energy, eliminate waste, reproduce, perform special functions
What are tissues
Cells the same type that join for a common purpose
What are the four tissue groups
Epithelial, connective, nerve, and muscle
What is connective tissue
Tissue that supports and protects such as fat blow bone and blood
What is epithelial tissue
Secrete and protect such as skin
What is nerve tissue
Controls and communicate such as nerves brain spinal cord
Is muscle tissue
Moves and protects
What are the three types of muscle tissue
Skeletal smooth and cardiac
What percentage of body tissues are is water
66 to 90%
Is dehydration
When tissue shrink with two little fluid
What is Edema
When tissue swell from too much fluid
What is homeostasis
The state of balance that the body tries to maintain and when body systems regulate internal environment for a stable and constant condition
What are some examples of the body trying to maintain homeostasis
Fluid balance blood pressure balance and temperature balance
What are the two things affecting fluid balance
Dehydration versus fluid retention
Are the two things affecting blood pressure balance
Cardiac output versus blood pressure
What are the two things affecting temperature counts
Hot and cold
What are organs
Two or more tissues join together for a specific function
