Hydrocarbons are organic compounds composed of hydrogen and carbon atoms. They are the fundamental building blocks of many organic substances, including fossil fuels such as coal, petroleum, and natural gas. Hydrocarbons are characterized by their carbon ske There are different types of hydrocarbons, classified based on the arrangement of carbon atoms and the types ofContinue reading “Hydrocarbon”

A hydrogen engine, also known as a hydrogen internal combustion engine (HICE), is an engine that burns hydrogen as its fuel source to generate power. Similar to traditional internal combustion engines, hydrogen engines use a combustion process to convert the chemical energy in hydrogen into mechanical energy. A hydrogen engine is an internal combustion engineContinue reading “Hydrogen engine”

Blood circulation, also known as the cardiovascular system or the circulatory system, is a vital process that transports oxygen, nutrients, hormones, and other essential substances throughout the body. It plays a crucial role in maintaining homeostasis, delivering oxygen to tissues, removing waste products, and supporting overall bodily functions. Circulation Summary Systemic circulation refers to theContinue reading “Systemic circulation of heart”

Photosynthesis is a process that occurs in plants, algae, and some bacteria. It is the primary means by which these organisms convert light energy into chemical energy, which is stored in the form of glucose or other carbohydrates. This process is crucial for life on Earth as it provides the oxygen we breathe and servesContinue reading “Photosynthesis”

Osmosis is a biological process that involves the movement of solvent molecules (usually water) through a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. It is a form of passive transport, meaning it does not require energy input from the cell. The semipermeable membrane allows the passageContinue reading “Osmosis”

The spinal cord is a long, cylindrical bundle of nerve tissue that extends from the base of the brain down the vertebral column. It is a crucial part of the central nervous system (CNS), along with the brain. The spinal cord is responsible for transmitting sensory information from the body to the brain and conveyingContinue reading “Spinal cord”

Ribe cage The term “rib cage” refers to the bony structure that surrounds and protects the thoracic cavity in vertebrates, including humans. It consists of twelve pairs of ribs that are attached to the spine at the back and curve around to the front, joining the sternum (breastbone) in the middle. The rib cage providesContinue reading “Rib cage”

Human brain The human brain is a complex organ that serves as the control center of the central nervous system in humans. It is responsible for processing information, coordinating bodily functions, and enabling conscious thought and awareness. Here are some key facts about the human brain: 1. Structure: The brain is located within the skullContinue reading “Human brain”
