Unit 1 Flashcards
Branch of science that deals with the structure or morphology of body parts, their forms, and how they are organized.
Anatomy
Deals with structures that cannot be seen without magnification.
Microscopic anatomy
Structure and functions of plant & animal cells
Cytology
Microscopic structure of tissues
Histology
Deals with the examination of large human structures of tissues.
Macroscopic anatomy or Gross anatomy
Study of the external features of the body
Surface or Visual anatomy
Anatomical organization of specific areas of the body, such as the head, neck, or trunk
Regional anatomy
Study of the structure of organ systems
Systemic anatomy
Deals with the changes that occur during the period between conception and physical maturity
Developmental anatomy

Regional Anatomy
Systemic Anatomy
Developmental Anatomy
It is the science of life
Physiology
It is the branch of biology that aims to understand the mechanisms of living things, from the basis of cell function at the ionic and molecular level to the integrated
behavior of the whole body and the influence of the external environment
Physiology
What’s the difference between Anatomy and Physiology?
Anatomy refers to the internal and external structures of the body and their physical relationships, whereas physiology refers to the study of the functions of those structures
Forms the external body covering which protects deeper tissue from injury, prevents dehydration and waterproofs the body
Integumentary system
Protects and supports body organs as well as provides framework to the muscles thus causing movement.
Skeletal system
Allows manipulation of the environment through locomotion and facial expression
Muscular system
What are the levels of structural organization?
Atoms -> Molecules -> Cells -> Tissues -> Organs -> Organ System
Responds to internal and external changes by activating appropriate muscles and glands
Nervous system
Production of offspring
Reproductive system
Secrete hormones that regulate processes such as growth, reproduction, nutrient use (metabolism) by cells.
Endocrine system
Compose of the heart, blood vessels and blood which carries oxygen, carbon dioxide, hormones, nutrients, wastes etc. to cells where exchanges are made
Cardiovascular system
Protects body from invading pathogens and disposes of dead cells.
Lymphatic and Immune system
Keeps blood constantly supplied with oxygen and removes carbon dioxide
Respiratory system
Breaks down food into absorbable units that enter the blood for distribution to body cells
Digestive system
What are the characteristics of life?
- Irritability
- Growth and Development
- Reproduction
- Movement
- Self-Regulating Metabolism
- Adaptation
The ability to react to a stimuli (any change from the external or internal environment)
Irritability
Production of new organisms and new cells
Reproduction
A change in position of a body or a part
Movement
are all chemical reactions happening in the body
Metabolism
___ comes in where body attempts to balance regulatory processes to control or regulate metabolism
Homeostasis
A change in the way of life that allows people to survive in a particular environment
Adaptation
The body’s ability to maintain relatively stable internal conditions even though the outside world changes continuously
Homeostasis
carry signals away from the central nervous system
Efferent pathways
come from outside stimuli and tell your brain what they are sensing, such as temperature
Afferent signals
produces change in the variable
Stimulus
detects change
Receptor
information sent along afferent pathway to control center
Input
