5.

6.

Stomach

Break down food and absorb the nutrients

7.

Liver

Secretes bile, that breaks down fat so it can be digested.
8.

Small Intestine

Breaks down most of the food and absorbes the nutrients.
9.

Large intestine

Compacts and dehydrates the undigested material.
10.

salivary glands

Makes enzymes to digest carbohydrates.
11.

gallbladder

Stores and concentrates bile for the liver.
12.

Endocrine system

Includes: Pituitary, hypothalamus, pancreas, and endocrine glands
13.

Functions of the endocrine system

  • Regulates body body temperature
  • Regulates metabolism
  • Regulates development and reproduction
  • maintains homeostasis
  • Regulates all other systems
14.

Pituitary Gland

Regulates other glands and produces growth hormones.
15.

Hypothalamus

Cordinates the endocrine and nervous systems.
16.

Pineal gland

Secretes the hormone melatonin which regulates the sleep cycle.
17.

Thyroid gland

Regulates the bodies metabolic rate, controls the production of proteins. 
18.

Parathyroid gland

Regulates the calcium metabolism and creates parathyroid hormone.
19.

Pancreas

Creates insulin and glucagon that raises or lowers glucose levels.
20.

Adrenal glAnds

Regulates responses to stress and control mineral balance in blood.
21.

ovaries and testEs

Regulates the hormones needed for reproduction.
22.

THE DIGESTIVE SYSTEM USEs

HORMONES FROM THE ENDOCRINE SYSTEM

23.

The digestive proceses use hormones

LIKE GASTRIN AND SECRETIN FROM THE ENDOCRINE SYSTEM  
24.

medical conditions

  • Gigantism
  • Dwarfism
  • Hypothyroidism
  • Appendicitis
  • Peptic ulcer
25.

Dwarfism

Dwarfism is caused by lack of growth hormone from the pituitary gland.
26.

GIGANTISM

Gigantism is caused by too much growth hormones to the pituitary gland. 
27.

These systems are related because:

  • The digestive system provides the energy while the endocrine uses/regulates
