Homeostasis in Humans

What is mean by homeostasis?

• Controls and coordinates body activities through chemical 
• controls and coordinates body activities through electrical impulses
• For maintenance of a steady state in the internal environment
• remove metabolic waste products from the cel

How blood osmotic pressure will regulate in our body?

• regulate the glucose level in the body
• regulate the amount of water and concentration of salt in the blood
• regulate concentration of carbon dioxide and oxygen
• regulate the level of hydrogen ions, hydroxide ions, hydrogen carbonate ions

If the environment gets cold, we will often shiver in order to:

• keep body temperature the same as the external temperature
• decrease body temperature
• increase body temperature
• regulate blood pressure

Why is the sensation of thirst important to maintaining homeostasis?

• Water removed by the kidneys must be replaced

• Oxygen cannot diffuse into cells if a person is dehydrated

• Water molecules are needed to carry carbon dioxide waste to the kidneys

About 85% of water is reabsorbed from the filtrate at

• Bowman's capsule.

• Proximal uriniferous tubule.

• Collecting duct.

• Henle's loop.

The substance present in blood passes through the glomerulus and the Bowman's capsule by a process called

• diffusion.

• ultra filtration.

• active transport.

• osmosis.

Reabsorption of useful substances from the filtrate begins at the

• Proximal tubule.

• Henle's loop.

• Collecting duct.

• Bowman's capsule.
