Chapter 1 Flashcards
Define Anatomy
The science of structure and the relationships among structures
Define physiology
Is the science of body functions, that is how the body parts work.
The six levels of organization of the human body
Chemical, cellular, tissue, organ, system, and organismal
Which two things are used in the chemical level
The chemical level includes atoms, and molecules.
What level do molecules combine to form structures at the next level of organization?
The cellular level
What are tissues?
Tissues are the groups of cells and the materials surrounding them that work together to perform a particular function.
What are the 4 basic types of tissue in the body?
Epithelial, connective, muscular, and nervous
At what level of structural organization has a recognizable shape and is composed of two or more tissues that have a specific function
The organ level
What is the largest level of structural organization
The organismal level
Describe the chemical level of organization in the human body
The chemical level of organization in the human body and provides the foundation of all higher levels of organization. This level includes Atoms and molecules. At this level interactions between atoms and molecules create the environment necessary for life.
Describe the cellular level of of organization in the human body
The cellular level bridges the gap between molecular and tissue levels. Theo organization is essential for understanding how tissues organs and systems function and interact within the human body.
What’s the basic difference between anatomy and physiology?
Anatomy focuses on the structure and the relationships among the structures, while physiology focuses on how the body works
Example of how the structure of the body is related to its function:
The bones of the fingers are more loosely joined which enables them to perform a variety of movements such as grasping an object.
Define atom
The smallest units of matter that participate in chemical reactions. Consists of nucleus (containing positively charged protons and uncharged neutrons) and negatively charged electrons that orbit the nucleus.
Define molecule
A combination of of two or more atoms that share electrons
Define cell
The basic structural and functional unit of all organisms, the smallest structure capable of performing all activities vital to life.
Define tissue
A group of similar cells and their intercellular substance joined together to perform a specific function
Define organ
A structure composed of two or more different kinds of tissue with a specific function and usually a recognizable shape.
Define system
An association of organs that have a common function
Define organism
A total living form; one individual
Which body systems help eliminate waste
Urinary system
digestive system
Respiratory system
Integumentary system
Lymphatic system
Define metabolism
Is the sum of all the chemical processes that occur in the body. It includes the break down of large complex molecules into smaller simpler ones and building up of complex molecules from smaller simpler ones
Define responsiveness
Is the body’s ability to to detect and respond to changes in its environment. Nerve cells respond to changes in the incitement by generating electrical signals, known as nerve impulses. Muscle cells respond to nerve impulses by contracting to move body parts

Define movement
Included motion of the whole body, individual organs, single cells, and tiny organelles inside cells.
Growth
Growth is an increase in body size, it may be due to an increase in the size of existing cells, the number of cells, or the amount of material surrounding the cells.
Differentiation
Is the process whereby unspecialized cells become become specialized cells. Specialized cells differ in structure and function from the unspecialized cells that gave rise to them. For example a single fertilized egg cell undergoes tremendous differentiation to develop into unique individual who is similar to, yet quite different from either of the parents
Define reproduction
Refers to either 1. the formation of new cells for growth repair or replacement or 2. the production of a new individual
What type of disease affects the entire body?
Systemic
Which organ system carries lipids from the gastrointestinal tract to blood
Lymphatic system
What is the correct order for a feedback system
Stimulus, receptor, control centre, effector, response
