System of the Human Body

The system of human body is actually a very complicated system and is difficult to understand. Still we shall try to study the system of our body which is as follows: The whole system is divided into different parts: Anatomy: Human Anatomy; Circulatory System; Digestive System; Nervous System; Muscle; Bone (anatomy); Respiration; Human Sexuality; Endocrine System; Immune System; Reproductive System; Lymphatic System; Cartilage; Urinary System. Muscle; Bone anatomy, the human skeleton consists of more than 200 bones bound together by tough and relatively inelastic connective tissues called ligaments. The different parts of the body vary greatly in their degree of movement. Circulatory System or cardiovascular system, in humans, the combined function of the heart, blood, and blood vessels to transport oxygen and nutrients to organs and tissues throughout the body and carry away waste products. Digestive System, series of connected organs whose purpose is to break down, or digest, the food we eat. Nervous system is composed of the central nervous system and the peripheral nervous system. The central nervous system, which includes the brain and spinal cord, processes and coordinates all incoming sensory information and outgoing motor commands, and it is also the seat of complex brain functions such as memory, intelligence, learning, and emotion. The peripheral nervous system includes all neural tissue outside of the central nervous system. It is responsible for providing sensory, or afferent, information to the central nervous system and carrying motor, or efferent, commands out to the body’s tissues. Respiratory System, in anatomy and physiology, organs that deliver oxygen to the circulatory system for transport to all body cells. Human Sexuality permeates many areas of human life and culture, thereby setting humans apart from other members of the animal kingdom, in which the objective of sexuality is more often confined to reproduction. Immune System group of cells, molecules, and organs that act together to defend the body against foreign invaders that may cause disease, such as bacteria, viruses, and fungi. The health of the body is dependent on the immune system’s ability to recognize and then repel or destroy these invaders. Endocrine System group of specialized organs and body tissues that produce, store, and secrete chemical substances known as hormones. Among their many jobs are regulating the body's growth and development, controlling the function of various tissues, supporting pregnancy and other reproductive functions, and regulating metabolism. Urinary System system of organs that produces and excretes urine from the body. The major organs of the urinary system are the kidneys, a pair of bean-shaped organs that continuously filter substances from the blood and produce urine. References: - Microsoft Encarta Encyclopedia.
