Anatomy has its roots in ancient times and has been around for thousands of years. Today, the field of anatomy continues to be studied and researched by scientists and physicians throughout the world.
The human body is made up of three separate systems: the muscular tissue; the nervous tissue; and the skeleton. These three separate systems are interrelated and together are known as the whole organism. Anatomy will tell you how all of these parts work together to support human life.
All cells of the body play a major role in supporting the life of the human being. They produce hormones, build muscles, produce red blood cells and perform many other functions. Many cells can be separated into two types: internal and external. Internal cells can be found inside the body while external cells are outside the body.
The body’s immune system works in conjunction with all of the other organs to protect the person from infectious organisms. A person has two sets of immune cells – white blood cells and white blood cell receptors. In order for a white blood cell, to be able to travel through the blood it must have antibodies.
The immune system helps keep diseases from attacking the body and keeping it healthy. Some diseases such as colds, viruses and even cancer can be prevented or controlled if the immune system is strong enough. All living things contain enzymes that break down food into smaller molecules called amino acids. This process breaks down proteins into peptides and small chains of amino acids known as peptide chains.
Metabolism is the use of energy to create and utilize the food in the body. It is the body’s primary source of energy. The body uses all of its energy to create heat, make energy, and break down food. Metabolism can also be used to create muscle tissue, chemicals and hormones.
Blood is a fluid-filled vessel that carries nutrients and wastes from cells to tissues where they can be used or disposed of. When nutrients and wastes from tissues are not properly utilized or disposed of, the waste builds up and is stored as urine. The purpose of urine is to remove wastes from the body.
The bones, muscles, nerves, organs and glands of the body are all connected to each other through the blood vessels. If a part of the body has problems, the problem spreads to all of the other parts of the body.
The body has four major organs which can be divided into different types. The liver is the organ that produces bile. The liver also produces some fats and proteins, which help break down the foods that are eaten into smaller particles for absorption into the bloodstream.
Stomach contains bile production, which helps to break down fats. The gallbladder is an organ that absorbs liquid that is excreted from the fat that is absorbed.
Bowels is the organ that produces bile and is responsible for digestion. Kidneys help break down sugar into the urine and fats which are excreted through the urethra.
Skin contains epidermis, hair, teeth, digestive system, and kidneys. Kidneys are important in the absorption and use of nutrients.
The body has several different systems that break down foods into usable substances. Digestion is a complex series of processes that involve the breakdown of protein, fats and carbohydrates into useful materials.
Bones are made of minerals that are broken down into tiny pieces. Bones break down into powder and are used for making everything from clothing to weapons.
Blood vessels are used to deliver oxygen to different parts of the body. They carry nutrients and blood to different parts of the body. When nutrients are not used correctly, the body can become weak and sick.
