Anatomy/Phys Intro
WEEK 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY
1. Define the terms anatomy and physiology, and explain their relationship using an example of a human structure with its corresponding function.
The term anatomy refers to the structure and relationship of body parts such as tissues and organs. Physiology on the other hand is how these structures work as in individual and in the body as a whole. Take the circulatory system for example. The heart itself, blood vessels and blood is the anatomy. How these vital parts work together to transfer oxygen, nutrients, and waste throughout the body is the physiology.
2. List, in order from least to most complex, the levels of structural organization, discuss the relationship between the levels, and name an example at each level.
The smallest level is the chemical level. Here atoms form together to create molecules. Next is the cellular level where these molecules have formed cells that are smooth muscle cells. When similar types of cells come together they form tissue thus creating the tissue level. These cells are also further divided into 3 types of tissue: Epithelial, smooth muscle, and connective. These tissues also create blood vessels which are formed together to make up the organ level. When various organs are formed, they have specific purposes. Those that work together create organ systems. Several organ systems are then created, each with its own vital function for life, make up an organism, the largest level of structural organization.
3. List the 11 organ systems of the human organism, name the major organs within each, and give a general function for each system.
The Integumentary system is the organ that protects the deeper tissues from injury because it is the outer covering of the human body. The major organ is the skin. The Skeletal system also protects and adds support to the body organs. It attaches to muscle to assist in locomotion as well. The major organ is
