M4 Explain positive and negative feedback in homeostasis using examples from the human body.
Negative feedback is the process which is used to describe how the body maintains our normal environments. Homeostatic is used on this process to help regulates our body system for example when your body is too hot it is cause by due to the extreme environment. if the body is too cold shivering is one of the responses which keep you up.
Another example of a negative feedback is the glucose regulation. glucose regulation is one of the most important things which is needed in order for us to have energy in our bodies. There are two importance hormones in our blood glucose regulation they include insulin and glucagon. What the insulin

What the tamoxifen does to the women body is that it stimulates the growth of follicles in the ovaries. It is a pills. It has some side effect on the women such as headache, nausea, insomnia, sweating. What the Pergo time does to the women body is that it stimulates its pituitary gland to produce more of the natural of FSH. This stimulate the growth of the follicles which are inside the ovaries. There are some side of Pergo time which are the breast tension, nausea feelings of warmth, headache, stomach ache blurred vision. these are some of the possible side effects on the hormones treatment of the women.
M5 Explain the semen analysis in men.
Semen analysis is a test which is carried out in a hospital to test whether a couple is able to conceive a child. The semen analysis is usually performed on fertility by taking two samples at least seven days more of that samples are taken period two or three months. The sperm count and the semen which is in the male may change from day to day. The reason is that they may have some medical conditions which can affect the sperm levels. The test is done by taking some sample from the males’ semen and check if they are normal.
How is semen analysis carried out?
The semen is done in the laboratory by taking by following some procedures. First the patient is given a specimen tubule and after that it will produce some semen into the bottle by
Homeostasis is what allows our internal system to maintain at a constant condition. In order to maintain equilibrium the body must communicate using the control system. It is essential that the body monitors its conditions whether that be blood pressure, thirst sensation or body temperature (this is either gained or lost). Negative feedback is most important and comes first, this allows for the body to correct itself and get back to a set point when it is off track. There are three components that link with this feedback. A sensor (receptor) sends signals to the control center that something is unusual, the control center compares the many values of our normal body range and decides
There is a variety of method which allows the separation of sperm but very few of these have withstood scientific checks which prove they work.
“Homeostasis in a general sense refers to stability or balance in a system. It is the body's attempt to maintain a constant internal environment. Maintaining a stable internal environment requires constant monitoring and adjustments as conditions change” (Human Physiology/Homeostasis, 2016). Negative feedback will operate to return Mrs. Loiselle’s body back to homeostasis in such a way her body, system responds in which it reverse the direction of changes. Since negative feedback tends to keep things constant, it allows the maintenance of homeostasis. As Mrs. Loiselle’s fainted by going for the run without eating something from last evening that made her week and she lost an enormous amount of energy in her exercise through sweating continuously. That made her dehydrated and because
Homeostasis is a characteristic of life in which all Living things maintain. some of the traits of Homeostasis are perspiration and some form of breathing and other natural body functions. An example of a negative feedback mechanism is a Thermostat If the heat is turned on and is set at 80 degrees the heat is turned on, If the temperature drops below 80 degrees, After the heater heats the house to 80 degrees, it shuts off keeping the desired temperature. An example of a positive feedback system is when a baby is born. while the mother is in labor, a hormone is released that boosts and quickens her contractions. The more contractions causes more of that Hormone to be let out and it continues to goes on until the
Homeostasis is a biological process that maintains a constant internal environment, regardless of what is going on in the external environment. This process ensures the bodily functions and chemicals are kept in a state of balance which in return allows the body to function optimally. Homeostasis requires coordination of the hormonal (endocrine system) and nervous systems, which together regulate the activity of the body’s organ systems. The regulatory activities are constantly adjusted in response to stimuli (change) from both the internal and external environment. A change influenced by the external environment can cause a state in the body that will take it away from the normal, the body will act to counteract this change and return the internal environment back to a steady state. This is negative feedback. Negative feedback has a stabilising effect reducing changes from a set point and returning internal conditions to a steady state. Most body systems e.g. controlling blood glucose levels, obtains homeostasis through negative feedback which makes the negative feedback system critically important in obtaining homeostasis. However there is also positive feedback which is a system that results in the escalation of a response to a stimulus. It causes instability in the system and is used when there is a specific outcome required. Positive feedback ceases once the natural resolution is reached e.g. baby is born, pathogen is destroyed, blood clot forms. This system is not used
The Mechanism of Negative Feedback Homeostasis means beatified sex. It is an ability of an organism to control its internal environment, that is the composition of their body fluids, for them to survive fluctuating external conditions. Homeostasis is used to describe all the mechanisms by homeostatic control. Maintenance of stability requires control systems capable of detecting any deviation from the usual and making the necessary adjustments to return it to its normal condition.
Semen is the male reproductive fluid, containing spermatozoa in suspension. Sperm is a male reproductive cell. Prostate is a gland surrounding the neck of the bladder in male mammals and releasing prostatic fluid. Urethra is a duct by which urine is convey out of the body from the bladder, and which in male vertebrates also conveys semen. Penis is the male genital organ of higher vertebrates, carrying the duct for the transfer of sperm during copulation. Glans is the head of a penis. A shaft is the cylindrical part of the penis between the scrotum and head. Seminiferous tubules is any of the numerous long convoluted tubules in the testis which are the sites where spermatozoa mature. Seminal vesicles is each of a pair of glands that open into the vas deferens near its junction with the urethra and secrete many of the components of semen. Bladder is a membranous sac in human and other animals, which urine is collected for excretion.
The body can regulate its internal environment through feedback systems. A feedback system is a cycle of events in which the condition of the body is monitored, changed, re-monitored and re-evaluated. Each monitored variable such as temperature, blood glucose and blood pressure is termed as a controlled condition. Any disruption that changes a controlled condition is called a stimulus. Only three components make up the feed back system - a receptor, a control center and an effecter.
Since the time of insemination is extremely important, your partner should be prepared to have to collect semen by masturbation in the clinic. The procedure may also cause discomfort to the woman if there are difficulties in catheter insertion. Furthermore, when possible insemination cramping like menstrual.
Negative feedback is what the correctional mechanism is doing, it is going to serve to turn it off. According to an article Homeostasis: Negative Feedback, Body Temperature, Blood Glucose it gives an example of another negative feedback which is blood glucose when blood rises then insulin is produced in the pancreas where it lowers our blood sugar and once it lowers it insulin production is stop (N.A
Negative and positive feedback loops assist the bodily systems to help keep control of their normal state. Negative feedback occurs when the internal system entirely stops or slowdowns the procedure that was taking place. Even though more than half of the control mechanisms in
It is common for the semen of 2-3 bulls to be used to ensure at least one quality sample to produce a pregnancy. In the instance that multiple donors are used, parentage is confirmed via DNA analysis. Most frequently, nonsurgical insemination is performed. This method calls for a trained and accommodating elephant as a large bore cannula is inserted into the lower urogenital tract. A 3m endoscope is inserted through the cannula and conducted to the hymen in first time mothers and the cervix or uterine horn of a cow that has calved. A small insemination cannula is used to deposit semen into the vagina, threaded through the hymen in nulliparous cows. In parous cows the semen may be deposited further into the uterus.14 Surgical insemination
The control of glucose levels in the blood is an example of homeostasis. Homeostasis is the body maintaining a stable internal state despite changes in the external environment. This homeostasis is achieved through negative feedback. Negative feedback is when a deviation of normal levels is brought back to the normal level by a corrective response. The larger the deviation from the normal, the greater the corrective response will be. The level of glucose in the blood achieves homeostasis by its removal from the blood being balanced with its entry into the blood.
The outcome from the system is also regulated by a feedback mechanism. In essence, the quantity of these hormones is in homeostasis
