Level 1
scientific discipline that investigates the structure of the body.
Anatomy
basic living units of all plants and animals, molecules combine organelles to form small structures.
Cell
What system provides protection and support, allows body movements, produces blood cells, and stores minerals and fat?
Skeletal System
What is the ability to use energy to perform vital functions?
Metabolism
The existence and maintenance of a relatively constant environment within the body.
Homeostasis
Scientific discipline that deals with the processes or functions of living things.
Physiology
a group of similar cells and the materials surrounding them
Tissue
What system consists of the mouth, esophagus, stomach, intestines, and accessory organs?
Digestive System
Condition in which the parts of the organism have specific relationships to each other and the parts interact to perform specific functions.
Body Organization
Positive and negative homeostatic mechanisms maintain a constant internal value.
Feedback Mechanism
Childbirth and nursing are examples of?
Positive Feedback
Chemical, cell, tissue, organ, organ system, organism
Organization of Human Body
What system removes foreign substances from the blood and lymph, combats disease, maintains tissue fluid balance, and absorbs fats from the digestive tract?
Lymphatic System
What is the ability of an organism to sense and go with changes in the environment?
Responsiveness or Adaptability
A normal value that is maintained by homeostatic mechanisms.
Set Point
Thirst, shivering, and increased heartbeat when exercising are examples of?
Negative Feedback
a group of organs classified as an until because of common functions
Organ System
This organelle contains digestive enzymes that break down materials.
Lysosome
Homeostatic mechanisms resist or shrink any deviation from a set point.
Negative Feedback
The receptor, control center, and effector are?
Components of Homeostasis
integumentary, skeletal, muscular, lymphatic, respiratory, digestive, nervous, endocrine, cardiovascular, urinary, reproductive
Organ Systems
A central regulatory system that influences metabolism, growth, and reproduction. It consists of glands that secrete hormones.
Endocrine System
This organelle is a network of tubes/membranes that transport materials throughout the cell.
Endoplasmic Reticulum
Non-Homeostatic responses that when a deviation from a set point occurs, the reaction is to make that deviation greater.
Positive Feedback
