Hormone & endokrines System by Julie B. on Prezi

The normal pH of blood is in the range 7. The result is that the blood system fails to deliver enough oxygen and nutrients to the cells, which stop functioning properly and may die. It is therefore important that the blood contains balanced quantities of acids and bases. There are two parts to this endocrine gland, an outer cortex and an inner medulla. Again it is the hypothalamus that monitors the concentration of the blood and initiates the release of hormones from the posterior pituitary gland.

It controls the autonomic nervous systemproduces a range of hormones and regulates the secretion of many others from the pituitary gland see Chapter 7 for more information on the hypothalamus. A nerve impulse travels rapidly and produces an almost instantaneous response but one that lasts only briefly. The pineal gland is found deep within the brain see diagram The body temperature of mammals and birds is maintained at an optimum level by a variety of heat regulation mechanisms.

Adrenalin is responsible for the so-called flight fight, fright response that prepares wystem animal for emergencies. Animals can only survive if the environment within their bodies and their cells endokrihes kept constant and independent of the changing conditions in endokrinew external environment.

The thyroid gland is situated in the neck, just in front of the windpipe or trachea see diagram Anatomy and Physiology of Animals.

English-German Dictionary

However, target cells are sensitive to subtle changes in hormone concentration and the endocrine system regulates processes by changing the rate of hormone secretion. For example, think sndokrines what happens when a male and female cat meet under your bedroom window at night. 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.

In other languages Add links. High level of melatonin in dim light makes an animal tired and depressed and therefore causes low fertility in animals. The adrenal medulla secretes adrenalin also called epinephrine. The animal will die unless a vet administers fluid or blood.

The endocrine part of the organ consists of small clusters of cells called Islets of Langerhans that secrete the hormone insulin.

The initial response of both cats may include spitting, fighting and spine tingling yowling – all brought about by the nervous system. In most animals the pancreas is an oblong, pinkish organ that lies in the first bend of the small intestine see diagram The adrenal glands are situated on the cranial surface of the kidneys see diagram Biochemical reactions within the body are very sensitive to even small changes in acidity or alkalinity i.

Policies and guidelines Contact us. In contrast, hormones act more slowly and their effects may be long lasting. This small but vital region of the brain lies just above the pituitary and provides the link between the nervous and endocrine systems. Cells around the sperm producing ducts of the testis produce the hormone testosterone.

The pituitary gland is divided into two parts with different functions – endokrimes anterior and posterior pituitary see diagram On the other hand, alkalosis blood that is too alkaline causes over stimulation of the nervous system and when severe can lead to convulsions and death. The biochemical and physiological processes in the cell are sensitive to temperature. This page was last edited on 12 Octoberat However, we now know that the pituitary gland is itself controlled by the hypothalamus.

From Wikibooks, open books for an open world. Biochemical processes in the cells, particularly in muscles and the liver, produce heat. The nervous and endocrine systems both work together to bring about this adaptation. It does this by increasing the absorption of sodium ions Na- from the kidney tubules. It produces the hormone melatoninwhich influences the development of sexual maturity and the seasonality of breeding and hibernation.

To add to the problem, chemicals called goitrogens that occur naturally in plants like kale that belong to the cabbage familycan also cause goitre even when there is adequate ensokrines available.

To do either requires instant energy, particularly in the skeletal muscles. For example, although it is carried to virtually every cell in the body, follicle stimulating hormone FSHreleased from the anterior pituitary glandonly acts on the follicle cells of the ovaries causing them to develop. The main endocrine glands in the body are the pituitary, pineal, thyroid, parathyroidand adrenal glandsthe pancreas, ovaries and testes.

The anterior pituitary gland secretes hormones that regulate a wide range of activities in the body. This mechanism is called feedback control. This is called acidosis and when severe can cause coma and death. Target cells respond to minute quantities of hormones and the concentration in the blood is always extremely low.

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.

A major symptom of this condition is glucose in the urine. Loss of blood or body fluids leads to decreased blood volume and hence decreased blood pressure. This stimulates the development of the male reproductive system and the male sexual characteristics – generally larger body of male animals, mane in lions, tusks in boars, etc.

Breathing is one of these mechanisms. Adrenaline increases the amount of blood reaching them by causing their blood vessels to dilate and the heart to beat faster.

These act on the kidney tubules to influence the amount of water and sodium ions absorbed from the fluid flowing along them. In mature animals it increases the rate of chemical reactions in the body. This hormone regulates the amount of glucose in the blood by increasing the rate at which glucose is converted to glycogen in the liver and the movement of glucose from the blood into cells.

Their positions in the body are shown in diagram
