The four basic human structure units are : * Cells * Tissues * Organs * Systems Cells : These are the basic structural unit of the body that maintain life. Every person consists of billions of cells that perform a infinite number of tasks in order to maintain the continuation of life. These live independently and can reproduce themselves. A cell also comes in different shapes and sizes depending on their function within the stability of life, for example, a mature red blood cell is less than 1mm in diameter and their function is to transport oxygen around the body. Tissues : Tissue is a collection of cells, not identical but a similar function, specialised to perform a specific function. Tissue comes in many different forms including blood, muscle, glands and bone(such as cartilage). These can also form nerve tissue to which are cells that specially conduct electrochemical nerve impulses throughout the body. Organs : All organs are formed when tissue combines with other forms of cells. This then gives you a structural unit, for example, a heart, that perform a specific function. Other examples of organs include the eye, liver, stomach, testis, uterus and kidneys all with their own particular function in sustaining life. Systems : System are cells, tissues and organs all working together to get a final outcome. For example, your digestive system needs a mouth,...

...1.1 Describe the four basic human body structure units and their functions The four basic human body structures and their functions are as follows: • Cells • Tissues • Organs • Systems Cells Cells have been identified as the simplest unit of living matter that can maintain life. A cell is the simplest and smallest unit of living matter and cells can live independently and can also reproduce themselves. Cells exist in a varity of shapes and sizes including elongated, oval, and square, cells also have many different function. A group of cells is called a tissue and the study of the structure, form of cells and tissue is called histology. Tissues Tissue is a group/organisation of a number of similar cells, not all identical but from the same origin, that carry out a similar function, which also consists of varying amounts and varity of non-living, intercellular substance between them. It is the level between cells and organs. There are four types of tissue: Epithelial – tissue that is widespread throughout the body. They form the covering of all the body surfaces and are the main tissue found in glands. Epithelial tissue performs a variety of functions that include protection, secretion, absorption, filtration and sensory reception. Connective - tissue that binds structures together, and forms a framework and support for organs and the body as a whole. Connective tissue also acts as a transport system for substances to be carried around the body, and...

The four basic human structures are cells, tissues, organs, and systems. The cell is the smallest building block of the body, and is the basic structural and functional unit of all known living organisms. They live independently and can reproduce itself. A group of cells form Tissues. They come in all different sizes such as elongated, square, oval and even star shaped. The cell is made up of protoplasm (jelly like substance), it is 70% water plus organic and inorganic salts, carbohydrates, lipids (fatty substance), nitrogenous substances, (these are amino acids obtained from protein), and compounds of all the above. Blood for example is a liquid tissue made up of several different types of cells. Cells allow us to breathe, digest, excrete, reproduce, sense, grow, move, die. When a cell goes wrong this can be the origin of disease and illness. Tissues, is a group or cells joined together, there is four different types of tissue, epithelial, connective, nervous and muscular. Epithelial There is two categories of epithelial tissue, simple and compound, simple is often found as a covering or lining...

...Clinical Notes The Visible Human Project p. 7 Homeostasis and Disease p. 13 An Introduction to Studying the Human Body This textbook will serve as an introduction to the inner workings of your body, providing information about both its structure and its function. Many of the students who use this book are preparing for careers in health-related fields—but regardless of your career choice, you will find the information within these pages relevant to your future. You do, after all, live in a human body! Being human, you most likely have a seemingly insatiable curiosity—and few subjects arouse so much curiosity as our own bodies. The study of anatomy and physiology will provide answers to many questions regarding the functioning of your body in both health and disease. Although we will be focusing on the human body, the principles we will learn apply to other living things as well. Our world contains an enormous diversity of living organisms that vary widely in appearance and lifestyle. One aim of biology—the science of life—is to discover the unity and the patterns that underlie this diversity, and thereby shed light on what we have in common with other living things. Animals can be classified according to their shared characteristics, and birds, fish, and humans are members of a group called the vertebrates, characterized by a segmented vertebral column. The shared characteristics and organizational patterns provide useful clues about how these animals have evolved over time...

...versus disease as an unbalanced state. The Western approach tends to change the environment and the Eastern way is to prefer to adapt to the environment. There are numerous difficulties in comparing these two approaches. The same terminology may apply to entirely different facts, the teaching and learning methods are quite different, and the evaluation of the treatment is almost not comparable. In order to help understand the Eastern approach better, an understanding is needed of the basic Chinese concepts: the concept of a small universe living in a large universe; the duality concept of yin and yang; the concept of anatomy; the concept of physiology in Chinese medicine-the state of equilibrium expressed by the five elements; the concept of pathophysiology expressed by the external and internal insults; the concept of maintaining and promoting health expressed by the circulation of chi and hsieh; the therapeutic concept in Chinese medicine-the normalization or reestablishment of balance of the body function; the concept of preventive medicine.

...i.e., law of nature in Taoism. The human body and almost all animals are symmetric, which shows a beauty of health and balance. Rather asymmetry leaves people an impression of displeasure. Symmetry is also the manifestation of Chinese philosophy of harmony and zhongyong (the Mean thought) in Confucianism. The aesthetic principle of symmetry in Chinese art is similar to the “Golden Rule” in the West, the aim of which is to achieve balance. This essay aims to discuss the aesthetic principle of symmetry used in Traditional Chinese Art and Design, including ancient Chinese Bronze artwork, ancient Chinese architecture and Chinese paper cutting. I. Symmetry in Ancient Chinese Bronze artwork Bronzes basically can be classified into four types in terms of function: food vessels, wine vessels, water vessels and musical instruments. Various shapes and designs can be found in each type, fully demonstrating the creativity and skills of the ancient people. Despite of this, symmetry was used as a universal basic aesthetic principle. Ancient Chinese bronzes stressed balance and symmetry of form, and communicated solemnity and ceremony. Among the various kinds of bronze vessels, ding is a significant category. Originally ding was used as food vessel and later evaluated to sacrificial vessel. Ding was describes as a kind vessel with three feet and two ears in Shuo Wen Jie Zi by XU Shen. Actually, most of the ding have three feet while some have four, like the famous Si Mu Wu Ding. In the...
