Elizabeth Maciel Digestive & Urinary System Period 3
Digestive enzymes
secreted by epithelial cells of the mucosa, and
embedded in their microvilli:
Salivary amylase
carbohydrate digestion by breaking
down starch
Pepsin
Begins protein digestion
Intestinal lipase
Breaks down fats into fatty acids and glycerol
Sucrase, maltase, lactase
Break down disaccharides into
monosaccharides
Peptidases
Breaks down peptides into amino acids
Nucleases
Break down nucleic acids into nucleotides
Pancreatic lipase
Breaks down fats into fatty acids and glycerol
Enterokinase
Converts trypsinogen into trypsin
Pancreatic amylase
Breaks down starch into disaccharides
Proteolytic enzymes
Break down proteins or partially digested
(a) Trypsin
(b) Chymotrypsin
(c) Carboxypeptidase
Major functions of the urinary system
Regulates pH and body fluid volume
Helps control red blood cell production and blood pressure
Filters salts and wastes from the blood
Location of digestion and absorption of each macromolecule
Nucleic Acids
Small intestines
Carbohydrates
Oral cavity and small intestines
Proteins
Located stomach and small intestines
Lipids
Oral cavity, stomach, and small intestines
Major functions of the digestive system
Digestion
mechanical and chemical breakdown of foods and
absorption of nutrients
Mechanical Digestion
breaks down large pieces of food into
smaller ones
Chemical Digestion
breaks down large nutrient molecules into
smaller chemicals
Major organs of the digestive system
Small Intestines
Stomach
Esophagus
Pharynx
Large Intestines
Rectum
Anus
Pancreas
Mouth
Major organs of the urinary systems
Urters
transport urine from kidneys to bladder
Urinary Bladder
stores urine
Kindeys
filter the blood
Urethra
conveys urine outside of the body
Layers of the GI tract
Submuscosa
Lies under muscosa
Muscularis
Propels food through canal
Muscosa
Inner layer
Serosa
Outer layer
Nephron
Can produce urine independently
About one million nephrons per kidney
Consists of Renal corpusle, and Renal tubule
Renal Corpusle
Filtration structure in renal cortex, which performs the first
step of urine formation
Renal Tubule
Consists of the following in this order
Glomerular capsule
Proximal convoluted tubule
Nephron loop
Distal convoluted tubule
Collecting duct
Disorders of the digestive and urinary systems
