COLORANTES

Why are they used?

  • To provide consistent color to food.
  • To replace color lost during processing.
  • To color foods that are naturally colorless (e.g., candy, imitation shellfish).
  • To improve the appearance of food.

ITEM 7 Parts of the Urinary System

Secretory (Kidneys)

: produces and secretes urine

Excretory

: expels urine out of tissues

Tips on Kidney Tissues

: medullary fibrous tissue is composed of native tissue and supporting tissue filler

Adrenal Glands

: located on the sup limb of the kidney, no renal function

Medulla Composition

: Pyramids of Malpighi are rectangular spaces within the kidney formed by tube straight uriniferous peeking into a pore

Cortical Substance Structures

: Ferrein Pyramids rest on the pyramids

ITEM 6: Digestive System

The Digestive Tract

The digestive tract is a series of interconnected organs responsible for the breakdown and absorption of food. It includes the following parts:

  • Mouth
  • Pharynx
  • Esophagus
  • Stomach
  • Small intestine (duodenum, jejunum, ileum)
  • Large intestine (cecum, colon, rectum)

Accessory Digestive Organs

Several glands play crucial roles in digestion by secreting enzymes and other substances:

  • Salivary glands
  • Liver
  • Pancreas

Organs Within the Mouth

The mouth contains various structures involved
