Functions of water in the body

FUNCTIONS OF WATER IN THE BODY Presented by Group 42 Tong Ling Yat (3036219190) Wong Yat Ho (3036221624) Chan Yu Wai (3036219607).

Water is an essential component of the human body. It makes up a significant portion of our body weight and is involved in various physiological processes Help to maintain hydration and fluid balance and more...... About 20% of daily fluid intake usually comes from food and the rest from drinks. Up to 65% of human body is made up of water About 15.5 cups (3.7 liters) of fluids a day for men. About 11.5 cups (2.7 liters) of fluids a day for women.(Mayo Clinic, 2022) Water?.

Important functions of water Hydration: Temperature maintenance Lubricate joints Skin health Digestion: Food Digestive track Metabolism: Energy production Waste removal Transportation: Dissovle important minerals and vitamins Waste removal Temperature maintenance: Heat redistribution Lubrication: Digestive track Joint.

Hydration is the replacement of body fluids lost through sweating, exhaling, and eliminating waste. Water is essential for maintaining proper hydration levels in the body. It helps to regulate body temperature, lubricate joints, and support various biochemical reactions. Hydration Source: RawBlend.

Drinking fluids is crucial to staying healthy and maintaining the function of every system in your body, including your heart, brain, and muscles. Fluids carry nutrients to your cells, flush bacteria from your bladder, and prevent constipation. Insufficient intake of water or excessive water loss in body may cause dehydration and fatigue.

Water is involved in various metabolic processes in the body. It helps in the breakdown of carbohydrates, proteins, and lipids, which are essential for energy production. Water is also required for the elimination of waste products generated during metabolism. Metabolism Source: lybrate.

Metabolism WritWater is involved in various metabolic processes in the body Breakdown of carbohydrates, proteins, and lipid . This breaks down large molecules into smaller molecules, which allow the absorption of the nutrients into the blood . This process are essential for energy production.

The skin consists of different layers, and the water content varies accordingly. The outermost layer, the epidermis, has a water content of about 15-30%. Sufficient water intake promotes healthy skin by keeping it hydrated and moisturized. It helps maintain skin elasticity, prevents dryness, and contributes to a glowing complexion.

Removing heat from body: Sweating The high heat capacity allows sweat to absorb more heat before it evaporated Heat redistribution : Blood circulation Blood circulate in our body and carry the heat around the body This redistribute the heat throughout our body Important property of water: High specific heat capacity (4.182 kJ) Regulation of body temperature.

Water as a carrier 1.Dissolving important minerals and water-soluble vitamins Minerals(like Ca, Na, K, Mg) and vitamins(water soluble, vitamin B and C) are needed to be dissolved in water, in form of ions, before absorption The polar properties of the water allow ions to separate from their crystal structure Credit: baristahustle.

Water as a carrier 2. Remove wastes from cell The intestines, kidneys and liver use water to help flush out waste through defecation, urination and perspiration. Fun Fact: There is no evidence to prove that increasing water intake will cure constipation..

Lubrication of food : When we masticate the food, we mix the food with the salivary. This soften and moisturize the food, allowing the food easier to swallow. Lubrication in the digestive track : Mucus acts as a lubricant, which is produced along the esophagus, stomach, and intestines Water also soften up and bulk up stool This allow stool to move smoothly through the digestive system Lubrication.

Joint lubrication Water forms a thin layer of fluid(called synovial fluid) between the joint surfaces, reducing wear and tear This reduce friction between the surfaces of joints, allowing them to move smoothly. Synovial fluid Credit : dkfindout.

Structural support Bilayer of cell membrane Phospolipid has a hydrophilic head and hydrophobic tail The phydrophilic head face the aqueous environment inside and outside of the cell and the hydrophobic tail points inward Credit : National Human Genome Research Institute.

Cell shape : Water help excert pressure on the cell membrane, and thus maintaining its shape This prevent the cell to wrinkle, which is important for function cell membrane Cushions for some organs : In our joints, brain and the spinal cord, there is some fuild that is very important can help us to cushions shocks Credit : Harvard Credit : kenhub Cerebrospinal fluid.

Causes of Dehydration Excessive sweating 1. Inadequate fluid intake 2. Vomiting and diarrhea 3. Other diseases 4. If your Water Gain < Water Loss, you will eventually dehydrate. Research Study : Dehydration and fatigue Source: greatwater.

Effect of dehydration Major symptoms of dehydration Fatigue/Drowsiness Feeling slowed down Difficulty in concentrating/remembering Balance Problems And many more! Very important to drink enough water J Athl Train et al. (2007) *Mean Sympton Score is calculated by measuring the total severity of the symptoms reported, then divided by the total number of symptoms reported.

Also reduce friction Brain and spinal cord Shock absorber Skin Maintain skin elasicity and regulate temperature Quick summary.
