Skin Wrinkling Lab

Have you ever soaked in the tub or swimming pool for an extended amount of time and either your fingers or toes, maybe both, began to feel smooth-like and wrinkly? For a long time, people assumed that the reason our fingers prune was for no reason at all. Moreover, scientists started to investigate and experiment on how and why our fingers prune when immersed in water. There has been much laboratory tests that showed that wrinkly fingers improve our grip. Likewise, an analogy scientist used to help get a better understanding that wrinkly fingers improve our grip was compared to the rain trends in car tires to help channel away the water. The biology goes beyond how our skin works and gives us answers on why our fingers prune after exposed

The purpose of this lab is to understand how to measure the heart rate and blood pressure of an individual by the appropriate method. It is important to know how to take these measurements accurately in the healthcare or fitness professions. In this lab, the heart rate was measured by a stethoscope over the chest, and with the middle and index fingers for the carotid and radial arteries. For blood pressure, a sphygmomanometer and stethoscope were used to identify the Korotkoff sounds that indicate the systolic and diastolic pressures. Risk factors such as heart disease and high blood pressure can be discovered through the

Ensuring that the patient was relaxed and comfortable I began to take her pulse, using my three middle finger tips to locate the pulse. I did so for 15 second and timed by fore for the next 15 seconds I measured her respiration rate and timed by 4. I did not explain to my patient that I was taking her respirations as looking at her chest may have made her feel uncomfortable and increase her respirations. Her pulse rate ending up being 85 beats per minute and respirations were 15 breaths per minute. These results were within normal range, as her pulse rate was between 80 and 120 bpm and respirations were between 12 and 20 (Tollefson, 2010). The change in pulse and respiration rate can increase during excercise. If a pulse is recorded below 50 bpm the patient can be at risk of a heart attach. A fast pulse exceeding 100 bpm can be a sign of infection or dehydration. This can be detected quickly and appropriate action taken to prevent negative affects on the patient’s well being.

The hypothesis: If exercise increases, then blood pressure and HR will increase initially as a result of increased QC, and as time progresses the initial increase in blood pressure and HR will adjust to their normal resting values, was not supported by the results (p-value>0.05). The initial rise in blood pressure can be tied to the increased need of oxygen delivery to the contracting muscle cells. The increase in oxygen demand causes an increase in hyperemia to the skeletal muscles3. The increased blood flow increases blood pressure as a result of increased QC. QC is also influenced by a high level of sympathetic nervous innervation3. By increasing sympathetic tone there is an increase in SA node pacing, increased contractility, and increased irritability of foci. All of this results in an increase in SV and inevitably increases QC. With the heart pumping faster and harder, blood pressure increases.

Wrinkles usually appear as a result of dry skin. Dermatologists recommend strict moisturizers to keep the skin hydrated regularly. So choose Vaseline instead of some expensive moisturizer! Leave it to penetrate deep into your skin, keeping it supple and soft, and prevent

The study into the mechanics behind abnormal thermoregulation has been investigated in different ways, however these two studies (as well as numerous others) agree that prolonged vasoconstriction of cutaneous blood vessels (post-denervation hypersensitivity) is a primary cause of the peripheral coldness experienced by many sufferers of PD. Different methods were used to observe this phenomenon, both of which are valid however they also deal with other variables. **Shindo et. al** chose to focus on electric stimulation producing a response, of which they measured skin sympathetic nerve activity, reflex burst amplitude, decrease of blood flow and recovery time. Ultimately the only variables which were relevant to the understanding of thermoregulation

During phase 1 and the beginning of phase 2, the variables measured were relatively stable as the body was in a homeostatic state and skin temperature was within a thermoneutral zone (34°C). Thus, thermoregulatory responses could be regarded as passive.

Dry skin can cause wrinkles. Dermatologists recommend people with dry skin to apply moisturizer frequently to keep the skin hydrated because it prevents wrinkles. How does Vaseline petroleum jelly prevent wrinkles?

The heart rate increases as activity intensity in the body increases. The cause of this increase in heart rate is due to the working tissues in the body increasing their need for oxygen and nutrients. The heart needs to pump faster to supply the tissues with an adequate amount of oxygen and nutrients needed for the muscles (Tortora & Derrickson, 2014, p. 716). During the increase of activity levels in the body and rise of heart rate, blood pressure is additionally effected because of the increased need of oxygen flow to tissues in use and cardiac output directly affects blood flow (Tortora & Derrickson, 2014, p. 741). Therefore the main focus of this report will be discussing the two main concepts of the effects of increased intensity of exercise on heart rate and blood pressure.

They say that if you treat your body right, it will treat you right back. Today’s hustle and bustle is not easy to get around. We sometimes forget to eat breakfast, let alone remember to take care of our body and skin. No matter how busy and hectic life gets, our priority should always be taking care of ourselves, as an unhealthy body cannot withstand pressure. Skin care is one of the most important body treatments, and we should always make time for it. Our skin is the first line of defence against the outside world, which contains bacteria and other harmful agents. Healthy skin ultimately means healthy body. Many of us have dealt with facial skin issues at some point or another in our lives. The issue we have

Regular consumption of alcohol will gradually dilate the small blood vessels in the skin and increase the blood flow near the surface of the skin, especially on the face. This condition can become permanent and create a flushed appearance caused by broken blood vessels. Alcohol also dehydrates the skin causing wrinkles.

There are biophysical devices with the capacity to determine various pressure injury-related skin parameters, such as hydration, colour (melanin and erythema) and lipids. This pilot study used a descriptive-correlational design to examine correlations between subjective (visual) assessment of skin hydration (dryness and wetness) and colour, as well as objective (parametric) assessment of skin hydration, colour and lipids at PI-prone areas amongst geriatric persons (n = 38). Twice daily measures of hydration, colour and lipids were assessed using a skin measuring device over pressure-prone areas of study participants over seven consecutive days. Concurrent visual assessment of hydration and colour was performed by the researcher. Results were

Normal skin carries a soft, supple texture due to the water content. For the skin to feel soft, pliable and "normal," its top layer must have a minimum of 10% water and ideally between 20% and 35%. To help protect the outer layer of skin from losing water, your skin layer's oil glands produce an oily substance called sebum. Sebum is really a complex mixture of sugars, and waxes along with other natural chemicals that form a protective barrier against water evaporation. If the skin doesn't have enough sebum, it loses water and feels dry. If environmental factors cause more water evaporation and overwhelm the ability of sebum to prevent water loss, your skin will shrivel and crack.

Drink plenty of quality water to keep your skin hydrated and flush out toxins. When toxins build up, they cause organs such as your kidneys to work less efficiently which has a direct impact on your skin.
