Functions of Digestive system

Organs of Urinary system

Elimination of waste products like toxins,drugs and nitrogenous wastes

Digestive enzymes

Layers of GI

Disorders of digestive/urinary systems

Nephron anatomy

Regulates aspects of homeostasis

Kidneys- filters about 200 liters of fluid daily

Ureters- transports urine from kidney to bladder

Urinary bladder- temporary storage reservoir for urine

Urethra- transports urine from bladder to the external environment

Structural and functional units of kidneys

responsible for forming urine

consists of Glomerulus and renal tubule

Volume and chemical makeup of the blood

Water and electrolyte balance

Acid base balance in the blood

Produce hormones

Renin- regulates blood pressure and kidney function

Erythropoietin- red blood cell production

Breakdown and absorption of food for metabolism

Mechanical digestion- physical breaking of large food pieces into smaller pieces

Chemical digestion- Breaks food into simpler chemicals that can be absorbed by cells in the body

Carbohydrates: Amylase-poly->di

Peptidase reduce peptides to amino acids

Maltase reduces maltose to glucose

Lactase reduces lactose to glucose and galactose

Sucrase reduces sucrose to glucose and fructose

Nuclease-> nucleotides

Lipase reduces fats into fatty acids and glycerol

Liver- helps maintain concentration of blood glucose levels, metabolizes proteins

Tongue- moves and mixes food with saliva

Gall bladder- concentrates and stores bile

Teeth- breaks down food

Pancreas- secretes pancreatic juice into duodenum

Mouth- opening for food and food enters the mouth

Lips- keeps food in mouth

Mucous membrane- produces mucus for reduction of friction and protections

Submucosa- Areolar connective tissue and has many elastic fibers

Muscularis layer- has two layers of smooth muscles to allow peristalsis and segmentation

Serosa- Areolar connective tissue and simple squamous epithelium and produces serous fluid

Salivary glands- keeps oral cavity moist

Pharynx- passage for food from mouth to esophagus

Esophagus- passageway only for food and connects pharynx to stomach

Stomach- mixes and holds the food

Hepatitis- inflammation of the liver

Cirrhosis- a chronic inflammation of the liver usually resulting from alcoholism or chronic hepatitis

Small intestine- absorption of water and nutrients

Large intestine- absorption of water and salts

Glycosuria- diabetes mellitus

Proteinuria- non- pathological: excessive physical exertion

Hemoglobinuria- transfusion reaction, hemolytic anemia

Bilirubinuria- liver disease

Hematuria- bleeding

Pyuria- urinary tract infection
