In our body the blood glucose levels are regulated by a negative feedback system. The negative feedback system is a type of homeostatic system, and allows the body to maintain homeostasis. It detects changes, using the sensor, (which in glucose regulation is the pancreas recognizing the change in levels of glucose in the blood), caused by the stimulus. Then the control centre (pancreas) which is the response to the change, sends a message to the effector (liver) to counteract the change. The effector acts about to bring the body to its original set
From the synaptic cleft, the ACh binds to the receptors located on the muscle fiber’s plasma membrane. After the ACh has found its way to the receptors and is bound to them, the muscle fibers become stimulated. The stimulated muscle fibers result in an impulse being generated. This impulse travels down the membrane until it reaches the Sarcoplasmic Reticulum. The Sarcoplasmic Reticulum is responsible for regulating the Ca2+ ion concentration.
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”.
Golbidi & Laher (2012) state that human may develop a different kinds of antioxidant system to govern ROS production and circulation. Performing aerobic exercise on regular basis slows down the build-up of ROS-mediated cell damage by enhancing the antioxidative protective mechanism in the heart or to be specific, myocardium. That to be said, exercise helps to increase antioxidant level. There is a link between myocardial antioxidants and exercise-induced cardioprotection that involves a contributory role for manganese superoxide dismutase (MnSOD) (Demirel, Powers, Zergeroglu, Shanely, Hamilton, Coombes, Naito, 2001). In general, whether it is short-term or long-term, aerobic exercise can increase the myocardial MnSOD activity (Demirel et.
Controlled Variables temperature, pH, sucrase + sucrose incubation time 4. Describe what is measured as an indicator of sucrase activity and why this is an indicator of sucrase activity. I believe glucose and fructose was used as an indicator because they are what produces sucrose and sucrose creates more sucrase activity. 5. Explain why denatured sucrase was used as a control.
Alternative Health Care Therapies Introduction Biofeedback therapy, also called biofeedback training is a technique in which you can learn how to train yourself to control involuntary bodily functions at will; like Asthma. There are three types of biofeedback therapy, and they are: Thermal biofeedback - which measures skin temperature. Electromyography - which measures muscle tension. Neurofeedback - which measures brain wave activity. Biofeedback may be used to improve health, performance, and the psychological changes that often occur in conjunction with changes to thoughts, emotions, and behaviour.
The cardiovascular system also known as the circulatory system consists of the heart and blood vessels. One of the most important jobs it has is to “circulate” blood. The heart works to pump the deoxygenated blood to the lungs for gas exchange while simultaneously pumping oxygenated blood to the body’s tissues. The blood vessels work to continuously bring the blood to all areas of the body which helps regulate body temperature. The flow of oxygenated blood to the tissues helps deliver nutrients such as amino acids and electrolytes, water and oxygen.
The endocrine system is such an important system to the body because it functions the bodies use of hormones. The body uses many different hormones and the endocrine system regulates these. When the glands of the endocrine system secrete the hormones, the hormones are put into the bloodstream to be sent to the different parts of the body. The glands that comprise the endocrine system are the hypothalamus, the pituitary gland, and the pineal gland which are all located in the brain, the thyroid, parathyroid, and thymus which are located in the throat, the adrenals and pancreas which are located in the body’s midsection, and the ovaries (female) and testes (male) which are located in the pelvic region. The system is so important because it regulates the body’s metabolism, growth and sexual development, digestion, heart rate, and many of the other body functions regulated by hormones.
HOW THE SKIN PROTECTS THE BODY The skin plays a major part in regulating human body temperature and protecting the body. It consists of two layers: the outer epidermis and the inner epidermis. Beneath these layer is the adipose tissue, which contains fat-rich cells. PROTECTION:The outermost layers of the skin are dead cells, this protects the living cells below from Infection, Mechanical, Dehydration. The epidermis protects the body from damage and acts as barrier to prevent the loss of water and the entry of pathogens.The epidermis is the outer layer of the skin.
