Biotechnology is the “technology based on biology.” Specifically, it involves the use of living systems and organisms—or their derivatives—to develop or make products for specific uses. Modern biotechnology is heavily underpinned by Genetic Engineering (recombinant DNA technology), which allows us to transfer specific genes from one organism to another to achieve desired traits.
The respiratory system is responsible for breathing and gas exchange, ensuring that oxygen reaches body cells and carbon dioxide is removed.
The circulatory system is responsible for the transport of blood, oxygen, nutrients, hormones, and waste products throughout the body. It helps maintain homeostasis and supports all vital organs.
The excretory system is responsible for removing metabolic waste products from the body and maintaining water, salt, and pH balance.
The nervous system controls and coordinates all body activities by receiving, processing, and transmitting nerve impulses. It enables the body to respond quickly to internal and external stimuli.
