...TMA 1 1. Describe the four basic human body structure units and their functions The four basic human body structure units and their functions are: Cells, Tissues, Organs, and Systems. Cells Humans and all living things are made up of about 100 trillion small cells that can only be seen via a microscope. Cells can reproduce themselves and live independently. Some cells are specialized and become a different shape and size (elongated, oval, square, flat etc) dependant on its function. Here are just a few examples: * Epithelial cells – can be flat, cubed or column shaped. They protect the bodies tubes and cavities. They also cover the body forming the epidermis (the upper layer of skin) * Sperm cells and egg cells – for reproduction (sperm cells are tadpole shaped and egg cells are circular shaped. * Red Blood cells – these are doughnut shaped cells without a nucleus. They carry haemoglobin which gives the cell its red colour and carries oxygen around the body via the blood stream. * White Blood cells – are irregular in shape and size. They also have a nucleus. When foreign invaders like bacteria or viruses enter the body they detect it and then destroy it. * Platelets – are small bits of cells that clot the blood when there is a cut such as with a knife or abrasions received in a fall. Tissues Tissues are a group of similar cells working together to perform a function. The four main tissue types in the body are Epithelial...

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.

...Huddersfield, West Yorks HD3 4LN HUMAN ANATOMY AND PHYSIOLOGY LEVEL 2 Assignment 1 TMA 1 1.1 Describe the four basic human body structure units and their functions? 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 for organs and vessels. Compound provides external protection and the internal elasticity. All in all the tissue performs a variety of functions including protection, secretion, absorption, filtration...

...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...

...approaches to the human body. It’s imperative to understand how the human body works and complex systems. The seven organizational approaches are body cavities, body planes and direction, anatomy and physiology, quadrants and regions, medical specialty, microscopic-to-macroscopic, and body systems. Besides the importance of just understanding the human body, each can be used when applying knowledge to practical use in the healthcare industry. All of these approaches are imperative to learn and understand when in the healthcare industry. The body cavity is the study of body organs and cavities within them. Body cavities help divide the body into sections or compartments and help give organs a particular “place” in the body. Harris (2005) stated, “Humans have four body cavities: (1) the dorsal body cavity that encloses the brain and spinal cord; (2) the thoracic cavity that encloses the heart and lungs; (3) the abdominal cavity that encloses most of the digestive organs and kidneys; and (4) the pelvic cavity that encloses the bladder and reproductive organs.” .This type of approach is often used when a particular organ is being studied as an entire system like the gastrointestinal system that is in the abdominopelvic cavity or the brain in the cranial cavity. Body cavities can also be useful for observing how a disease affects numerous organs within the human body. Body planes and direction is the human body division. It involves four different sections...

...1.1 Describe the four basic human body structure units and their functions The way in which physical processes and functions take place in the body can be looked at on four main levels, moving progressively from the detailed to the general. At the most detailed level are the cells – the most basic of the physical structure units. Similar cells, when combined and held together, form tissue, the next main structure unit. Organs are collections of tissues that are combined to perform a particular function in the body. Organs do not work in isolation, however, and combine with other organs to create a biological system. Cells The cell is the most basic structural unit in the body. There are around 300 different cell types in the human body. While they differ in function, there are certain fundamental components or features that they generally have in common, such as a nucleus (with the exception of red blood cells), cytoplasm and a cell or plasma membrane. A cell membrane is composed of 60% protein, and 40% lipid, or fat. This membrane is a phospholipid bilayer which contains embedded protein molecules. It is a living boundary separating the living contents of the cell from its environment. Its function is to regulate the passage of molecules into and out of the cell. Within the membrane, the cell consists of cytoplasm, a gel-like substance containing organelles - small structures each with their own function. Common to all human cells except red blood cells, the nucleus is...

...Five Major Structures of the Brain Carolyn Jenkins University of Phoenix PSY 240 Pamela J. Reeves Introduction The brain is such an awesome machine with so many intricate working parts and components all working together at the same time for optimal functioning. Pinel, J. (2011) describes the neurons and synapse as highways and byways that seem to haul information and travel them to the body for several different functions. This essay will explain five parts of the brain, the Myelencephalon, the Met encephalon, the Mesencephalon, the Diencephalon, and the Telencephalon which all structure and cause different functions in the body. Myelencephalon The Myelencephalon is the part of the brain that has many functions; for example it causes all autonomic functions. Another function is the breathing portion of the body and the paths that all of the nerve tracts take as well. Digestion, Heart Rate, Swallowing, and Sneezing are also functions of the Myelencephalon which are all located in the brain stem and structured on the medulla oblongata. It seems that this portion of the brain carries many signals to the brain and throughout the body. Metencephalon According to Nakamura, H. (2008), “Primary brain vesicles such as the prosencephalon, mesencephalon and metencephalon are made and subdivided into secondary brain vesicles: the telencephalon, diencephalon, mesencephalon, metencephalon and myelencephalon (P.113).” Essentially the Metencephalon is the place...
