Liver-ing The Life
This reddish-brown organ produces bile and detoxifies harmful substances.
What is the liver?
This highly toxic waste product is formed when amino acids are deaminated in the liver.
What is ammonia?
This organ filters blood, removes waste, and produces urine.
What are the kidneys?
This is the functional unit of the kidney where filtration occurs.
What is the nephron?
Homeostasis maintains a stable internal environment by responding to these changes.
What are stimuli?
The liver receives oxygen-rich blood from this artery.
What is the hepatic artery?
Ammonia is converted into this less toxic compound for excretion in urine.
What is urea?
This kidney region contains nephrons and appears granular in texture.
What is the renal cortex?
These two parts make up the renal corpuscle.
What are the glomerulus and Bowman’s capsule?
This part of a homeostatic system detects changes in the environment (stimuli).
What is a receptor?
In the urea cycle, ammonia combines with this molecule to form urea.
What is carbon dioxide (CO₂)?
This waste gas is a byproduct of cellular respiration.
What is carbon dioxide (CO₂)?
These muscular tubes carry urine from the kidneys to the urinary bladder.
What are the ureters?
This fenestrated structure creates high hydrostatic pressure to filter blood into the nephron.
What is the glomerulus?
Sweating to cool the body is an example of this type of feedback mechanism.
What is negative feedback?
The liver detoxifies harmful compounds like alcohol and excretes bilirubin, a byproduct of this molecule.
What is hemoglobin or red blood cells?
Excess sodium, potassium, and chloride are excreted through these two routes.
What are sweat and urine?
The detrusor muscle in this organ contracts to release urine.
What is the urinary bladder?
This hormone increases water permeability in the collecting ducts.
What is ADH (antidiuretic hormone)?
Blood clotting is an example of this feedback mechanism that amplifies changes.
What is positive feedback?
Bile is stored and concentrated in this organ before being released into the small intestine.
What is the gallbladder?
Excess ammonia in the bloodstream can harm the body by disrupting this critical physiological balance.
What is homeostasis?
This urinary sphincter is controlled voluntarily and prevents urine leakage.
What is the external urinary sphincter?
The descending limb of the Loop of Henle reabsorbs this substance.
What is water?
Homeostasis works to maintain this specific range or level for a given physiological variable like temperature or pH.
What is the set point?
