In this process cells use oxygen gas and produce carbon dioxide gas — a waste product that must be removed from the body. The process of breathing allows these gases to be exchanged between the blood and lungs.
Reproductive system The human body has a system of organs that work together for the purpose of reproduction. The biological purpose of this process is the continuation of life.
Nervous system The nervous system is made up of a network of specialised cells, tissues and organs that coordinate and regulate the responses of the body to internal and external stimuli. Equipped with his five senses, man explores the universe around him and calls the adventure science. Our five senses make up a system within the nervous system. They are responsible for receiving information from the environment outside the body and relaying it to the brain for processing.
Scientific knowledge is concerned with understanding how individual parts of a system work and how these systems work together to create a whole. Add to collection. Our skin also helps regulate body temperature and eliminate waste through perspiration. In addition to skin, the integumentary system includes hair and nails.
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. The human heart is a responsible for pumping blood throughout our body. The job of the kidneys is to remove waste and extra fluid from the blood. The kidneys take urea out of the blood and combine it with water and other substances to make urine. The liver has many functions, including detoxifying of harmful chemicals, breakdown of drugs, filtering of blood, secretion of bile and production of blood-clotting proteins.
The lungs are responsible for removing oxygen from the air we breathe and transferring it to our blood where it can be sent to our cells. The lungs also remove carbon dioxide, which we exhale.
You use your eyes to see, your ears to hear and your muscles to do the heavy lifting. Even seemingly unrelated body systems are connected.
Your skeletal system relies on your urinary system to remove waste produced by bone cells; in return, the bones of your skeleton create structure that protects your bladder and other urinary system organs.
Your circulatory system delivers oxygen-rich blood to your bones. Meanwhile, your bones are busy making new blood cells. Working together, these systems maintain internal stability and balance, otherwise known as homeostasis. Disease in one body system can disrupt homeostasis and cause trouble in other body systems.
October 27, September 2, August 6, The nervous system allows us to perceive, comprehend, and respond to the world around us.
