Study Notes
- Water is essential for the human body and is required for its structure and various physiological activities.
- The human body is made up of 60-70% water, with two-thirds of this water found inside cells (intracellular) and the remaining in the extracellular space.
- Water plays a crucial role in protecting the body from injuries and maintaining the proper functioning of organs and systems.
- Water helps regulate body temperature and sweating is one of the ways water helps in temperature regulation.
- Water is an important solvent in biological processes and can dissolve a variety of polar substances, allowing for the transportation of nutrients, oxygen, and waste products in the body.
- Water facilitates chemical reactions, such as hydrolysis, which breaks down larger molecules into smaller ones.
- Water is involved in immune responses, as it is present in the lymph and mucus, helping to remove infectious agents from the body.
- Water molecules are polar, which allows them to form bonds with other polar molecules, making it a versatile and important compound in biological systems.
