Human A and P: Introduction to Body Fluids

what are the fluids in your body composed of?

• water

• dissolved substances

• electrolytes

what tract do we ingest water through

GI tract, gastrointestinal

where are the fluids absorbed in the body?

they are absorbed in the plasma in the intestine 

what happens when the fluids are circulating 

they are circulating in the plasma and bathing the cells in the body 

what happens with excretion

the kidneys removes excess ion and water from the body through urine 

How does water help with temperature regulation in the body?

water helps maintain body temperature through vaporizing off the skin and taking large amounts of heat with it, cooling the body down.

Does water have a high or low heat capacity?

Water has a high heat capacity

What does water having a high heat capacity mean?

That it can absorb or release large quantities of heat before significantly impacting the body temperature.

How much water is our body made of?

50-70%

Since our bodies are made of 50-70% of water

it helps hold heat in out bodies and prevent the body temperature from fluctuating

Water acts as a protective cushion in

amniotic fluid and cerebrospinal fluid

Water acts as a lubricant in

serous fluid, joints, and in the gastrointestinal tract

Water is a reactant for

hydrolysis reactions that occur in our body

What happens to water with the help of enzymes 

water molecules are added to the bonds between the glucose unites in the starch(known as hydrolyzing that starch to glucose)

water can also form some chemical reactions in the body such as

reactions that produce metabolic water

water acts as a solvent meaning

it dissolves molecules and ions in the body

what type of molecule is water

polar molecule
