Macrophages are major sentinels of the lung, functioning as the first line of defense against inhaled pathogens. They are located in the alveoli, interstitium, airways, pleura, and in some species, the vasculature. The macrophage is a large white blood cell that is an integral part of our immune system. Its job is to locate microscopic foreign bodies and 'eat' them. Macrophages use the process of phagocytosis to engulf particles and then digest them

Robotics is Devices that act largely, or partly, autonomously, that interact physically with. People or their environment and that are capable of modifying their behaviour. Based upon sensor data, an advanced robotics programming concept is the use of sensors, such as touch, ultrasonic, or light sensors that allow a robot to interact with the real world around it. Based on movement and sensors, robots can now also use cognition to plan its next move. Robotics is a part of Engineering and Science. It has to do with the creation and building of robots, as well as computer programming. Some robots look like humans, but most just look like machines. Robotics comes from the word robot, which in turn comes from the Slavic word robot.
