The main systems of the human body are: . Describe the structure of the human body in terms of six levels of organization List the eleven organ systems of the human body and identify at least one organ and one major function of each Before you begin to study the different structures and functions of the human body, it is helpful to consider its basic architecture; that is, how its smallest parts are assembled into larger structures. Dominique Green Chapter 1 Learning Objective 1. The Chemical Level of Organization. Human organs are organized into organ systems, many of which are shown in Figure below. Chemical Level 2.) It then covers the characteristics of life and how the body works to maintain stable conditions. Levels of Structural Organization in the human body. Human body cavities are separated by membranes and other structures. Chapter 1. A drag-and-drop exercise completes the activity. Learning Objectives. 3.) You may be surprised to know that all complex animals consist of only four basic types of tissues. The force generation required for skeletal muscle function occurs at the molecular level. Chapter 1. Organ level 5.) 1. Define terms that describe the body and its structural units. Digestive system and Excretory system: . Circulates blood around the body via the heart, arteries and veins, delivering oxygen and nutrients to organs and cells and carrying their waste products away. Chemical level– is the simplest level within the structural hierarchy. The human body is incredibly complex, but it does have an underlying organization. Identify the basic structural elements of the human cell, describing the functions of each element. CHAPTER 1: INTRODUCTION TO THE HUMAN BODY At the end of this chapter, student will be able to: a) Define the terms anatomy, physiology, and pathophysiology. An Introduction to the Human Body. Two essential molecules a. DNA b. Glucose. Most processes that occur in the human body are not consciously controlled. Describe, in order from simplest to most complex, the major levels of organization in the human organism All living and non-living things are made of one or more unique substances called elements , the smallest unit of which is the atom , (for example, the element oxygen (O) is made of O atoms, carbon (C) is made of C atoms and hydrogen (H) is made of H atoms. Chapter 1. 1.0 Introduction; 1.1 How Structure Determines Function; 1.2 Structural Organization of the Human Body; 1.3 Homeostasis; 1.4 Anatomical Terminology; 1.5 Medical Imaging; Chapter 2. Cellular level. If a longitudinal section of the kidney is made by cutting with a long knife from the outer convex surface to the hilum three layers are seen. Cells form tissues, Tissues form Organs, Organs form Systems. ADVERTISEMENTS: Internal Structure of Kidney: Human kidney is like that of a goat or sheep. The Chemical Level of Organization. Organismal level. Organization of the Body Objectives: On completion of this chapter, you should be able to: Briefly describe the amazing human body. Question: Chapter 1-The Human Body: An Orientation List And Describe The 6 Levels Of Structural Organization From Least To Most Complex. Circulatory system / Cardiovascular system: . by the structural design and relationships of the various body parts that carry out each of these functions. Describe the four basic structural levels of the body, differentiating among each level. An organ is a structure that consists of two or more types of tissues that work together to do the same job.
