What is the function of the stomach?
Mixes food with acid and breaks it down into a liquid.
What is the function of the pyloric sphincter?

Duodenum, jejunum, and ileum.
What happens in the small intestine?
Breaks food down more and absorbs nutrients into the blood.
What is the function of the liver in digestion?
Makes bile to help digest fats and cleans toxins.
What is the function of the gallbladder?
The gallbladder stores and releases bile to help digest fats in the small intestine.
What is the function of bile?
Bile breaks down fats into smaller droplets so enzymes can digest them more easily.
What is peristalsis and why is it important?
Peristalsis is wave-like muscle movement that pushes food through the digestive tract.
What is chyme and where is it formed?
Chyme is the thick liquid mixture of partially digested food and gastric juices formed in the stomach.
Large Intestine
Absorbs water and forms solid waste (poop). remains the the colon(12-24hrs)
Pancreas
Makes enzymes that help digest food and controls blood sugar.
What is the difference between the renal artery and the renal vein?
The renal artery carries blood to the kidneys to be filtered, and the renal vein carries cleaned blood away from the kidneys back to the heart.
functions of the parts of nephron ( bowman, glomerulus, loop of henle)
bowman’s capsule: contains glomerulus glomerulus: cluster of capillaries where waste products are flitered from blood. loop of henle: area of where the reabsorption of water happen
What is urea and what is the role of the liver in this process?
Urea is a waste product made when the body breaks down proteins. The liver converts toxic ammonia into urea, and the kidneys remove urea in urine.
