The systems of the body includes the circulatory, immune, skeletal, excretory, muscular, endocrine, digestive, nervous and respiratory.
The circulatory system is the body's transport system. It is made up of a group of organs that transport blood throughout the body. The heart pumps the blood and the arteries and veins transport it. Oxygen-rich blood leaves the left side of the heart and enters the biggest artery, called the aorta. The digestive system is made up of organs that break down food into protein, vitamins, minerals, carbohydrates, and fats, which the body needs for energy, growth, and repair. The human body includes the entire structure of a human being and comprises a head, neck, trunk (which includes the thorax and abdomen), arms and hands, legs and feet. Every part of the body is composed of various types of cells, the fundamental unit of life. The study of the human body involves anatomy and physiology. The human body can show anatomical non-pathological anomalies known as variations which need to be able to be recognised. Physiology focuses on the systems and their organs of the human body and their functions. One of the most important systems in your body, the nervous system is your body's control system. It sends, receives, and processes nerve impulses throughout the body. These nerve impulses tell your muscles and organs what to do and how to respond to the environment. The digestive system is made up of organs that break down food into protein, vitamins, minerals, carbohydrates, and fats, which the body needs for energy, growth, and repair. Human anatomy is the study of the systems of the body which is made up of cells, tissues, and organs. Human anatomy is important to study to help explain how organs and other structures of the body work. There are eight systems in the human body. Each system relies on the other to keep the body functioning. The systems of the body includes the circulatory, immune, skeletal, excretory, muscular, endocrine, digestive, nervous and respiratory. It is important to understand how human body systems work together. Body systems. Our bodies consist of a number of biological systems that carry out specific functions necessary for everyday living. The job of the circulatory system is to move blood, nutrients, oxygen, carbon dioxide, and hormones, around the body. It consists of the heart, blood, blood vessels,arteries and veins. Vital organs. Humans have five vital organs that are essential for survival. These are the brain, heart, kidneys, liver, and lungs. The human brain is the body's control center, receiving and sending signals to other organs through the nervous system and through secreted hormones. It is responsible for our thoughts, feelings, memory storage and general perception of the world This activity should help teach students that organs within a system work together to make that system function, and it should be pointed out that in turn all systems function together to make the human body function. At this point, ask students to name any other body systems. Context. At this level, children can begin to view the body as a system, in which parts do things for other parts and for the organism as a whole. Through the use of an online interactive activity, children learn about the concept of separate components working together to build a body system. The respiratory system brings oxygen into the human body and gets rid of carbon dioxide. The body needs oxygen to live. The organ used in the respiratory system is the lungs. Inside the lungs are tiny sacs. There are eight systems in the human body. Each system relies on the other to keep the body functioning. The systems of the body includes the circulatory, immune, skeletal, excretory, muscular, endocrine, digestive, nervous and respiratory. It is important to understand how human body systems work together. The organ systems of the body include the musculoskeletal system, circulatory system, digestive system, endocrine system, integumentary system, urinary system, lymphatic system, immune system, respiratory system, nervous system and reproductive system. 1 Integumentary System: The integumentary system is the organ system that protects the body from damage, comprising the skin and its appendages (including hair, scales, and nails). 2  Respiratory System: A respiratory system’s function is to allow gas exchange.
