The Endocrine System

By Fordo Harris and Brennan Lantzy

System Organs

The Endocrine System is a collection of glands that make hormones that regulate metabolism, growth and development, tissue function, reproduction, sleep, mood, and other things. Some major organs include the pituitary gland, the pineal gland, the thyroid gland, and the parathyroid glands.

Follicular Cell

These cells are the cells of the thyroid. Follicular cells are simple cuboidal epethelium. Follicular cells have thyrotropin receptors on their surface, which react to thyroid simulating hormones

Thyroid Tissue

Thyroid tissue contains follicules and colloid. It's function is to transport iodine.

Thyroid

Is one of the largest endocrine glands in the body. Consists of two connected lobes. It controls how quickly the body uses energy, makes proteins, and controls the body's sensitivity to other hormones

Endocrine System

The Endocrine System stabilizes blood sugar, it makes and secretes chemical messengers essential for homeostasis. It includes such organs as the thyroid, thymus, adrenal glands, and the pancreatic islets.

Organism

The thyroid is found in the neck below the adam's apple. It produces thyroid hormones, which contain thyroxine. The thyroid can be affected by many common diseases.

Homeostasis

Endocrine Homeostasis

The Endocrine System helps maintain homeostasis by controlling our growth and body changes. Hypothyroidism, a major disease of the endocrine system, occurs when the thyroid produces excessive amounts of hormones this affects homeostasis because the body gets hot very easily.

Working Together

Nervous System and Endocrine System

The Nervous System and the Endocrine System work together by sending hormones to cells and thereby causing a physical reaction. These hormones provide feedback to the brain and affect neural processing, they give your body instructions on how and when to react to certain external stimuli. Other hormones, such as reproductive hormones, affect the development of the nervous system.

Digestive System and Endocrine System

The Endocrine System works with the Digestive System through the pancreas, which produce hormones. When we digest carbohydrates (through the digestive system) they are then transformed into sugars. The pancreas, which is part of the Endocrine System, produce hormones to regulate how quickly the sugars are broken down; therefore, some hormones regulate the amount of sugar in the blood.

Circulatory System and Endocrine System

The Endocrine System works with the Circulatory System to aid in the transportation of the chemical messengers that the endocrine system produces. It basically works with the Circulatory System to send hormones throughout the body where they can be received by various organs and cells, and are then put to use through bodily functions.
