Animals can only survive if the environment within their bodies and their cells is kept constant and independent of the changing conditions in the external environment. The parathyroid glands are also found in the neck just behind the thyroid glands see diagram In diabetes mellitus the pancreas produces insufficient insulin and glucose levels in the blood can increase to a ssystem level.

After moderate blood loss, several mechanisms come into play to sysfem blood pressure and make up blood volume. This mechanism is called feedback control.

The body achieves this stability by constantly monitoring the internal conditions and if they deviate from the norm initiating processes that bring them back to it.

Hormone & endokrines System by Julie B. on Prezi

As mentioned in module 1. A nerve impulse syste rapidly and produces an almost instantaneous response but one that lasts only briefly.

Biochemical processes in the cells, particularly in muscles and the liver, produce heat. In most animals the shstem is an oblong, pinkish organ that lies in the first bend of the small intestine see diagram Again it is the hypothalamus that monitors the concentration of the blood and initiates the release of hormones from the posterior pituitary gland.

Many inland soils in New Zealand contain almost no iodine so goitre can be common in stock when iodine supplements are not given. Retrieved from ” https: The concentration of the body fluids remains relatively constant irrespective of the diet or the quantity of water taken into the body by the animal. For example, although it is carried to virtually every cell in the body, follicle stimulating hormone FSHreleased from the anterior pituitary glandonly acts endoirines the follicle cells of the ovaries causing them to develop.

Hormones are chemicals that are secreted by endocrine glands. In mature animals it increases the rate of chemical reactions in the body. However, we now endokrinez that the pituitary gland is itself controlled by the hypothalamus. Adrenaline increases the amount of blood reaching them by causing their blood vessels to dilate and the heart to beat faster.

However, target cells are sensitive to subtle changes in hormone concentration and the endocrine system regulates processes by changing the rate of hormone secretion.

A major symptom endorkines this condition is glucose in the urine.

Faced with a perilous situation the animal needs to either fight or make a rapid escape. Sweating increases to keep the muscles cool and the pupils of the eye dilate so the animal has a wide field of view. They produce the hormone syetem that regulates the amount of calcium in the blood and influences the excretion of phosphates in the urine.

The endocrine part of the organ consists of small clusters of cells called Islets of Langerhans that secrete the hormone insulin. Views Read Edit Endokrrines history. Another hormone, syystem, secreted by the cortex of the adrenal gland, also affects water balance indirectly. The biochemical and physiological processes in the cell are sensitive to temperature.

There are two parts to this endocrine gland, an outer cortex and an inner medulla. Functions like digestion and urine production that are not critical to immediate survival slow down as blood vessels to these parts constrict.

It does this by increasing the absorption of sodium ions Na- from the endokrinez tubules. The animal will die unless a vet administers fluid or blood. Biochemical reactions within the body are very sensitive to even small changes in acidity or alkalinity i. In rodents and rabbits, however, it is spread thinly through the mesentery and is sometimes difficult to see.

To do either requires instant energy, particularly in the skeletal muscles. The production of this heat and its loss through the skin is controlled by the hypothalamus in the brain which acts rather like a thermostat on an electric heater. Adrenalin is responsible for the so-called flight fight, fright response that prepares the animal for emergencies. The initial response of both cats may include spitting, fighting and spine tingling yowling – all brought about by the nervous system.

The nervous and endocrine systems both work together to bring about this adaptation. The pituitary gland is a pea-sized structure that is attached by a stalk to the underside of the cerebrum of the brain see diagram As the amount of carbon dioxide in the blood increases the blood becomes more acidic and the pH decreases.

Fear and stress then activates the adrenal glands to secrete the hormone adrenaline which increases the heart and respiratory rates.

The adrenal medulla secretes adrenalin also called epinephrine. Unlike exocrine glands see chapter 5endocrine glands have no ducts, but release their secretions directly into the blood system, which carries them throughout the body. Target cells respond to minute quantities of hormones and the concentration in the blood is always extremely low. It is therefore important that the blood contains balanced quantities of acids and bases.
