Multicellular Organisms Flashcards
Explain the Process of Nephrons
The glomerulus filters your blood, and the tubule returns needed substances to your blood, and removes waste.
Role of Nephrons in the digestive system
Regulate blood acidity, and remove toxic wastes from blood.
Which substances can be filtered through nephrons?
Proteins, water, glucose.
What can’t go through capillaries?
Red blood cells
What are villi’s?
Increase the surface area of a membrane.
Where does urea go after being in the collecting duct?
The collecting ducts pump urea into the medulla.
Role of Blood capillaries in renal tube.
Allows reabsorption and secretion between blood and the inner lumen of the nephron
Induced fit theory:
When a substrate is joined with the enzyme’s active site, the active site changes its shape to mould around the substrate. This increases the rate of a chemical reaction.
How is a long renal tube with large surface area helpful.
To maximize the absorption and secretion of solutes.
Why are thin walls helpful within the renal tube?
Allow smaller molecules, wastes, and fluids to pass into the tubule.
Explain first step in the process of nephrons
The glomerulus filters your blood.
Explain second step in the process of nephrons
The tubule returns needed substances to your blood, and removes waste.
