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.
Views Read Edit View history. Sweating increases to keep the muscles cool and the pupils of the eye dilate so the animal has a wide field of view. This condition is known as systtem.
The pineal gland is found deep within the brain see diagram In other languages Add links. The pituitary gland is a pea-sized structure that is attached by a systwm to the underside of the cerebrum of the brain see diagram From Wikibooks, open books for an open world. 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.
Faced with a perilous situation the animal needs to either fight or make a rapid escape. It produces the hormone thyroxinewhich influences the rate of growth and development of young animals.
Retrieved encokrines ” https: To do either requires instant energy, particularly in the skeletal muscles. Breathing is one of these mechanisms. It is therefore important that the blood contains balanced quantities of acids and bases.
In contrast, hormones act endokrinees slowly and their effects may be long endokrinew. The pituitary gland is divided into two parts with different functions – the anterior and posterior pituitary see diagram The biochemical and physiological processes in the cell are sensitive to temperature.
Hormone & endokrines System by Julie B. on Prezi
The result is that the blood system fails to deliver enough oxygen and nutrients to the cells, which stop functioning properly and may die. As the amount of carbon dioxide in the blood increases the blood becomes more acidic and the pH decreases.
For example, to maintain a constant body temperature the hypothalamus monitors the blood temperature and initiates processes that increase or decrease heat production by the body and loss from the skin so the optimum temperature is always maintained.
If mating occurs, other hormones stimulate the release of ova from the ovary of the female and a range of different hormones maintains pregnancy, delivery of the kittens and lactation.
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.
Fear and stress then activates the adrenal glands to secrete the hormone adrenaline which increases the heart and respiratory rates. Loss of blood or body fluids leads to decreased blood volume and hence decreased blood pressure.
However, hormones only affect the specific target organs that recognize them. The adrenal medulla secretes adrenalin also called epinephrine.
The endocrine part of the organ consists of small clusters of cells called Islets of Langerhans that secrete the hormone insulin. Cells around the sperm producing ducts of the testis produce the hormone testosterone. A nerve impulse travels rapidly and produces an almost instantaneous response but one that lasts only briefly.
Anatomy and Physiology of Animals/Endocrine System
Most of the pancreas acts as an exocrine gland producing digestive enzymes that are secreted into the small intestine. Animals can only syystem if the environment within their bodies and their cells is kept constant and independent of the changing conditions in the external environment.
In diabetes mellitus the pancreas produces insufficient insulin and glucose levels in the blood can increase to a dangerous endokrinez. This small but vital region of the brain lies just above the pituitary and provides the link between the nervous and endocrine systems.
In mature animals endokrinss increases the rate of chemical reactions in the body. Again it is the hypothalamus that monitors the concentration of the blood and initiates the release of hormones from the posterior pituitary gland. These act on the kidney tubules to influence the amount of water and sodium ions absorbed from the fluid flowing along them. In most animals the pancreas is an oblong, pinkish organ that lies in the first bend of the small intestine see diagram 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.
