What does the liver do?
The liver is the largest solid organ and the largest gland in the human body. It carries out over essential tasks. Classed as part of the digestive system, the roles of the liver include detoxification, protein synthesis, and the production of chemicals that help digest food. This MNT Knowledge Center article will cover the main roles of the liver, how the liver regenerates, what happens when the liver does not function correctly, and how to keep the liver healthy. Weighing between 3. It is situated above and to the left of the stomach and below the lungs.
The human body is everything that makes up, well, you. The basic parts of the human body are the head, neck, torso, arms and legs. 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. The digestive system consists of a series of connected organs that together, allow the body to break down and absorb food, and remove waste.
Younger primary students may have little knowledge about internal bodily organs. They tend to think the contents of the body are what they have seen being put into or coming out of it, such as food and blood. Their experiences with everyday cuts, scratches and bruises seem to reinforce a view that blood is below the surface of the skin, filling the spaces inside the body like a bag of blood. Older children are more likely to be able to list a large number of organs but may not fully understand the function or interconnected nature of these. For example, students at these levels may realise that the heart is a pump but not realise that the blood returns to the heart, or they may believe that the brain helps the body parts but not always realise that the body helps the brain. To survive and reproduce, the human body relies on major internal body organs to perform certain vital functions.
List of systems of the human body
Different organs can work together to perform a common function, like how the parts of your digestive system break down food. We refer to an integrated unit as an organ system. Groups of organ systems work together to make complete, functional organisms, like us! There are 11 major organ systems in the human body. The circulatory system is a body-wide network of blood, blood vessels, and lymph. Read more.
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell. Human cells contain the following major parts, listed in alphabetical order:.
