taking in of nutrients

Breakdown of complex organic molecules into smaller components

Transport of digested nutrients to the cells of the body

Removal of food waste from the body

Responsible for chemical and physical digestion

-Amylase
-Water
-Mucin

-Nasal Cavity
-Trachea
-Mouth Cavity
-Esophagus

Storage of food, Liquefaction of food, beginning of protien digestion

1.HCL
2.Pepsinogen -> Pepsin
3. Mucous
4.Horomones (Gastrin)

-Removes toxins from the blood
-maintains blood sugar
-regulates blood clotting
-sorts, stores, breaks and builds, balances, and produces nutrients, waste and enzymes
-regulates glucose
-produces urea

-Alkaline Salts
-Tripsinogen -> Trispin
-Erepsin
-Amylase
-Lipase

Duodenum, Jejenum, Ileum
-Majority of Digestion
-Proteases and carbohydrases digest food molecules

-litlle wave hairlike things obn the ridges of small intestines
-increase surface area

-Absorbs vitamins B and K, water, and ions
-Stores waste material
-Feces then build up and go to the rectum

1.Sensory Organs Stimulation
2.Mechanical Stimulation
3.Hormonal Stimulation

Convert toxin products into less harmful molecules and/or remove these products from the body

-Clean waste products from the blood
-Filled with millions of Nephrons

Bean shaped parts of the immune system
Swell due to signs of infection

-Blood enters thru renal artery
-Arterioles that are rebranched form the glomerules
-Proximal Tubule extends off bowmans capsule and absorbs 80% of sugar, filtrate, salt, etc.
-A loop forms and water/salt move by passive transport
-Distal tubule leads to a colleting duct and recieves urine
-Urine is carries to the renal pelvis and stored in the bladder

1. Filtration
2. Reabsorbtion
3.Secretion

-Produced in the hypothalamus
-releasted into blood and targets the collecting duct and distal tubule
-makes these tubes selectiviley permeable
-Causes less urine production

-Produced in the adrenal cortex
-targets nephrons and stimulates the reabsorption of Na ions in the loop of henle
-causes blood volume and pressure to increase

Causes nephrons to retain H2O
-makes urine more dilute and frequent

Blood is removed from your body through the needle. It's sent across a special filter, which removes harmful substances from the blood. Then, clean blood is sent back into the body

1. Blood runs through tubes of semiporoud membranes
2. Bloodrea is filtered and removed w a sterile solution
