How do we excrete?
Big Ideas
100
Main functional and structural unit of Kidney responsible for filtering blood. Each Kidney contains approximately 800,000-1.5 million of these.
What is the nephron.
100
Extremely toxic substance formed we our body metabolizes proteins.
What is Ammonia.
100
This process occurs usually during intense activity. Also functions to cool body down and regulate temperature.
What is sweating.
100
The excretory is like a bicycle in that all of its components and parts do not serve the same function or purpose when separates, but when working together they form an intricate and complex filtration process that is vital to our bodies. This reflects the concept of...
What is emergent properties.
200
Massive capillary located in the nephron that filters blood using blood pressure.
What is the glomerulus.
200
Nitrogenous wastes that our body turns ammonia into because they are less toxic but still must be excreted from the body.
What is urea and uric acid.
200
The substance excreted from our bodies most usually when we are sick. Protects against infectious agents such as fungi, bacteria and viruses. The average human body produces about a liter of this substance per day.
What is mucus.
200
The hormone ADH is produced in the brain when water levels in body fluids are too low. Once the ADH has done its job to signal enough water from the filtrate back into our body fluids, the release of ADH from the brain stops. This is an example of
What is negative feedback response
300
Location in nephron where final sodium regulation takes place and where the filtrate is processed into urine.
What is the collecting tubule or duct.
300
The substance formed when nitrogenous wastes, water, and nutrients have all been filtered out of our body fluids and collected in one place.
What is filtrate.
300
Main way we excrete wastes from our body. Drinking plenty of water is necessary to keep this process functioning smoothly.
What is urination.
300
The excretory system functions to balance water and solute concentrations in the body (Osmoregulation) and to make sure our body stays unharmed by toxic substances we consume. This is an example of maintaining...
What is homeostasis.
400
Part of nephron that surrounds the glomerulus and is only permeable to small solutes and water.
What is the Bowman's capsule.
400
The final substance that is to be excreted from the body, can no longer reabsorb nutrients or water from this.
What is urine.
400
The process is occurring continuously. Helps us to rid CO2 from our bodies.
What is exhalation.
500
Its main function is to create a concentration gradient in the medulla of the kidney and plays a role in the concentration of urine.
What is the Loop of Henle.
500
colorless, odorless, tasteless, and kills uncounted thousands of people every year. Main component of acid rain. Excess ingestion can lead to bloated feeling, nausea, vomiting and body electrolyte imbalance. Also known as hydroxyl acid.
What is water.
500
This is NOT one of processes of the excretory system and involves the digestion of food.
What is bowl movements.
