excretion and waste mangement biology

The Five Primary Metabolic Waste Products and how they leave the body

Ammonia - Leaves the body through the liver.

Urea - Leaves the body through the kidneys and skin.

Mineral Salts - Leaves body through kidneys or skin. Carbon Dioxide - Leaves the body through the lungs.

Water - Leaves the body through the kidneys, skin, and lungs.

How Toxic Waste Ammonia Is Produced and How It Is Taken Care Of.

Amonia is Produced when protein and amino acids are broken down. Ammonia is taken care of through the urea cycle.

Ammonia is toxic to our body so letting it accumulate in our bodies can cause damage to our cells and organs. It is so toxic that the amount of water needed to dilute it is too great.

Parts of the Urinary System

Kidney - A filter system for your body, removes waste from blood and produces urine.

Ureter - Connects the kidneys to the bladder. Transports urine from the renal pelvis into the bladder.

Bladder - Functions as a reservoir for urine until excretion occurs.

Urethra - Urethra allows urine to pass out the body.

How does a Nephron work?

The glomerulus found on the nephron filters your blood and the tubules return needed substances to your blood and removes waste.

3 Processes that occur to produce urine

Filtration, Reabsorption, and Secretion.

What is a filtrate?

A filtrate is liquid that has been passed through a filter.

Which materials are reabsorbed and which ends up as urine.

Glucose, amino acids, Sodium Chloride, and essential salts are reabsorbed, and urea ends up as urine.

What is osmoregulation, how does the body achieve it?

It is a process that regulates osmotic pressure of fluids and electrolyte balance in organisms. It is detected by osmoreceptors in the hypothalamus. The kidneys help maintain the osmoregulation of the body.
