Chapter 1 - Organization and General Plan of the Body Flashcards
Define:
Anatomy
The science that studies the structures of living things
ie: the structures of cells, tissues, and organs
Define:
Physiology
The study of how the body functions
ie: What cells do, how they do it, how it relates to the the body
Define:
Pathophysiology
The study of disorders of functioning
Mention:
Two Major Categories of Chemicals
Inorganic Chemicals and Organic Chemicals
Explain:
Inorganic Chemicals
Usually simple molecules made of one or two elements and does not have a covalent bond between hydrogen and carbon
ie: water, oxygen, and carbon dioxide
Explain:
Organic Chemicals
Often very complex and always contain the elements carbon and hydrogen
Explain:
Cell
The smallest living units of structure and function
Explain:
Tissue
Group of cells with similar structure and function

Mention:
4 Main Types of Tissues
- Epithelial tissues
- Connective tissues
- Muscle tissues
- Nerve tissue

Explain:
Epithelial tissues
They cover or line body surfaces and some are capable of producing secretions with specific functions.
ie: Skin, sweat glands, walls of capillaries, kidney tubules
Explain:
Organ
A group of tissues precisely arranged so as to accomplish specific functions.
Explain:
Organ System
A group of organs that all contribute to a particular function.
ie: urinary system, digestive system, and respiratory system
Explain:
Metabolism
Connective tissues
Muscle tissues
They are specialized for contraction, which brings about movement.
Connective tissues
They connect and support parts of the body and some transport or store materials.
ie: Blood, bone, cartilage, and adipose tissue
Muscle tissues
They are specialized for contraction, which brings about movement.
Nerve tissue
They are specialized to generate and transmit electrochemical impulses that regulate body functions.
ie: Optic nerves
