Exocrine Glands – glands may become blocked‚ produce excessive secretions Sweat Glands – extreme decrease in salt reabsorbtion‚ resulting in high salt content in sweat. Lungs – Mucus plugging‚ chronic bacterial infections‚ pronounced inflammatory response‚ damaged airways leading to respiratory insufficiency

Understanding the functions of the body systems associated with energy metabolism Energy is used for many of the bodily functions including the ability to ventilate‚ respire‚ move‚ grow and repair. The first law of thermo dynamics states that energy can be transformed from one state to another but cannot be lost. Energy comes in many forms‚ some of these are as follows:- Light Sound Kinetic Heat Chemical In accordance with the First Law an example of how energy can transform is when the sun creates

system What it consists of The male reproductive system consists of two major parts: the testes‚ where sperm are produced‚ and the penis. The male reproductive organs are the penis‚ the testicles‚ the epididymis‚ the vas deferens and the prostate gland. Having the testes outside the abdomen facilitates temperature regulation of the sperm‚ which require specific temperatures to survive. If the testicles remain too close to the body‚ the higher temperature will likely harm the spermatozoa‚ making conception

I. Introduction (pp. 526–528‚ Figs. 14.1–14.2) A. Comparison of the Somatic and Autonomic Nervous Systems (pp. 526–527; Fig. 14.2) 1. The somatic nervous system stimulates skeletal muscles‚ while the ANS innervates cardiac and smooth muscle and glands. 2. In the somatic nervous system‚ the cell bodies of the neurons are in the spinal cord and their axons extend to the skeletal muscles they innervate. The ANS consists of a two-neuron chain. 3. The neurotransmitter released by the somatic motor

two. Just like everything else in our body‚ the digestive system is a process and is made up of different components that all work together. The digestive system starts with the saliva in your mouth. The salivary glands recognize the sight and smell of food. The saliva contains the enzyme salivary amylase which begins the chemical digestion of food. The food you eat is moistened‚ chewed up by your teeth and then is transferred into a bolus. Once the bolus leaves the mouth‚ it moves into your pharynx

To numerous people‚ pigs are a nuisance. They are usually viewed as dirty animals with no purpose other than for food. However‚ pigs contribute greatly to the environment. They are able to digest certain substances easier than humans and use resources to make life easier for us. On the other hand‚ phosphorus‚ one of the many essential nutrients for swine‚ has negatively impacted the environment due to swine excretions. Elevating this problem has led to the genetic improvement of swine. Phosphorus

control system of ductless glands that secrete chemical "instant messengers" called hormones that circulate within the body via the bloodstream to affect distant cells within specific organs. Endocrine glands secrete their products immediately into the blood or interstitial fluid‚ without storage of the chemical. Hormones act as "messengers‚" and are carried by the bloodstream to different cells in the body‚ which interpret these messages and act on them. Typical endocrine glands are pituitary‚ thyroid
