Homeostasis is the process of keeping of the internal environment of cells constant. It ensures that the changes that occur do not threaten to interfere with the proper functioning of the body. If the body detects changes in its working conditions, it brings about corrective changes to avoid repercussions of the change. The homeostatic mechanisms have at least three independent components, namely a receptor, integrating center, and effector. The receptor senses change in the environment known as stimuli and then sends the information to the integrating center. The integrative center sends instructions to the effectors. The effector then brings about the response that solves restores the variable to normal. The nervous system and the endocrine system help in coordination in animals. However, the endocrine system comprises of endocrine glands that are ductless which secrete hormones. The interaction between these hormones forms a communication network in the body. They work together in order to maintain homeostasis. Both the nervous and endocrine systems interact to bring about the homeostasis mechanisms. Nerve endings detect changes in the internal and external environment and relay the information to the brain. The hypothalamus and pituitary are endocrine glands situated in the brain.

Nerve endings detect changes in the internal and external environment and relay the information to the brain. The hypothalamus and pituitary are endocrine glands situated in the brain. The hypothalamus detect changes in the blood while the pituitary secretes a number of hormones involved in the homeostasis such as the antidiuretic hormone (ADH). The ADH controls the amount of water and is produced by the pituitary gland. On the other hand, Aldosterone controls the amount of salt and is produced by the adrenal glands. For example, if there are changes

The posterior lobe is then responsible for storing the hormones made by the neurons of the hypothalamus. The hypothalamo-hypophyseal portal system is the specific way the hypothalamus communicates with the anterior lobe of the pituitary gland. This portal system consists of blood vessels that carry hormones of the hypothalamus to the anterior lobe. The anterior lobe then responds by making its own hormones. The anterior lobe hormones can go and control other glands.

Define homeostasis and explain its significance. - Ability to maintain relatively stable internal conditions even though the outside world changes continuously. Indicates dynamic state of equilibrium, or a balance, in which internal conditions vary, but always within relatively narrow limits. In general, the body is in homeostasis when its needs are adequately met and it is functioning smoothly. 8) Describe how negative and positive feedback maintain body homeostasis.

The PNS contains somatic nervous system and the autonomic nervous system. The autonomic nervous system controls the function of internal organs like your heart, stomach, cardiac muscle, and your glands. The autonomic nervous system has an effect on the organs, muscles, and glands are all done voluntary. The autonomic nervous system can change the body temperture, send extra blood to a particular area, slow your heartbeat, and pull the stomach secretion. The somatic nervous system is made up of sensory organs and nerves that connects to the skin, also that connects to all the skeleton muscles.

According to Martini, F., Tallitsch, R., Nath, J., (2018), the ANS functions outside of our conscious awareness and makes routine adjustments in our body’s systems (Martini, Tallitsch, & Nath, 2018, p. 450). The autonomic nervous system helps maintain the homeostasis of our bodies by regulating body temperature and coordinating cardiovascular, repertory, digestive, excretory, and reproductive functions. Efferent axons innervate the visceral organs and the efferent nerve fibers and ganglia of the ANS organize in two systems or divisions. The sympathetic division and the parasympathetic division. The sympathetic division is most active during times of stress, exertion, or emergency, also known as “flight or fight”.

Homeostasis is the body's method of keeping internal stability no matter what external influence disturbs its normal functioning (Anna, 2011). And the respiratory system is one of the systems in the body that helps to maintain homeostasis by maintaining pH and regulating gas exchange. The main function of this system is take in oxygen and get rid of carbon dioxide. This system has external respiration and internal respiration. External respiration is a mechanical process that exchange of gases in and out of the body, while internal respiration is the chemical process that breaking down nutrients with oxygen to produce energy.

Sympathetic and Parasympathetic Nervous System Salma Ewing Feb 15, 2018 The sympathetic and parasympathetic nervous system are two divisions of the autonomic nervous system of the body. They are very closely related and coordinated with each other and regulate the unconscious functions of the body. The autonomic nervous system is responsible for our involuntary reactions and controls our heart beat, digestive processes, blood flow and hormone production. This means that we can’t consciously control whether our heart beats or not.

The nervous system is a compound set of specialized cells and nerves that integrate the voluntary and involuntary actions of the body and send signals between different parts of the body. When it comes to structure, the nervous system has two main parts: the peripheral nervous system and the central nervous system. The peripheral nervous system is made up of ganglia and nerves outside the brain and spinal cord. The central nervous system consists of the spinal cord, nerves and brain.

11. Explain how certain amounts and types of food can affect hunger and satiation. (max. 2 marks) The type of macronutrient a person consumes affects hunger and satiation, for instance, proteins have the strongest effects of satiation compared to carbohydrates and fats. Also, solid products that are rich in water and fibre have greater satiety values rather than those that don’t contain these characteristics.

The anterior pituitary is devoid of a nerve supply, but has a unique blood supply, a portal system. The hypothalamohypophyseal portal system begins in a series of capillaries in the median eminence of the hypothalamus sends blood via veins to the anterior lobe, where it ends in a series of capillaries. This portal system carries neurohormones from the hypothalamus to the anterior pituitary where they control the secretion of anterior lobe hormones. The anterior pituitary consists of five different endocrine cell types, identified by antibodies against pituitary hormones and capable of production and secretion of pituitary hormones: 1.
