increases while you work out because your muscles start to make increased amounts of carbon dioxide which causes you muscles to fatigue.Also the amount of air taken in from each breathe increases.The changes in the cardiovascular system is that the blood is able to carry more oxygen which helps to prevent muscle fatigue. Your heart rate increases

“Survival of the Sickest” by Dr. Sharon Moalem 1) What prompted the author’s interest in biology? The author’s grandfather was a strong, loving man that loved bleeding. He loved donating blood because it made him feel great both emotionally and physically. The reason behind his physical please from donating blood was because he was diagnosed with hemochromatosis or iron overload disease. Her father passed away early but she was still motivated to find a cure to hemochromatosis for others with the

Abstract The Effect of Drugs on a Daphnia’s Heart Rate This experiment attempts to perceive the effects of certain chemicals, caffeine in cola, and alcohol. The daphnia was dropped into each of these solutions while we observed them for 15 seconds at a time. The heart rate was the dependent and main variable in the experiment. We record the number of heart beats in 15 seconds and then multiply it by for to

Biology Sem3 Assignment – Blood Diseases Leukaemia is cancer of the body’s blood-forming tissues, containing the bone marrow and the lymphatic system (7). There are many types of leukaemia exist. Some forms of leukaemia occur commonly in adults, other forms of leukaemia are more usually in children. Leukaemia usually contains the white blood cells. Your white blood cells are powerful infection fighters. They normally grow and divide in a proper way as your body needs them. However, the bone marrow

NUR209 Module 6 Identify two (2) variables needed to promote the accuracy of pulse oximetry results in the newborn. Discuss why these variables are important to address. One of the variables needed to promote the accuracy of pulse oximetry results would be the flexibility of the fit. A flexible fit for all finger sizes from adults to pediatrics. Also to be accurate with low circulation or dark skin tones. A good to low perfusion. Another variable needed is a pulse oximetry that is easy to clean

2. What are the normal ranges for the measurements listed in the blood and urine tests? The measurements taken will be through Arterial Blood Gas analysis which is used to diagnose the patient’s oxygenation levels, ventilation status, and acid-base balance. Normal PH blood levels are 7.35-7.45 which measures acidity or alkalinity. Normal Pco2 is 35-45 mmHg which measures carbon dioxide in the blood. Normal Bicarbonate is 22-26 mEq/L which acts as a buffer. Urinalysis PH levels range different from

1. Explain how the different solutions affected the frog heart. Be sure to include specific information from the lab and then relate the results to how the heart functions in the body normally and in conjunction with the sympathetic and parasympathetic nervous system. The regular solution values throughout the experiment for amplitude, interval, frequency, cardiac output is as respectively followed, 4.9, 0.96, 62.5, and 307. The cold solution caused the amplitude, interval, frequency, and cardiac

stimulates the production of cortisol, which is a vital stress hormone, by the adrenal glands. Adrenal glands are the small glands that sit on top of the kidneys.Cortisol has a number of functions. It promotes normal metabolism, maintains blood sugar levels and blood pressure, provides resistance to stress and acts as an anti-inflammatory agent. It also plays a part in regulation of fluid balance in the body.When we’re under stress, cortisol is produced largely. The second secretion is prolactin. Prolactin

which includes capillaries, vessels, cells, organs, ducts, lymph nodes and valves which all contribute to linking different structures together in order to transport excess fluid from the body tissues to the bloodstream and permeate pathogens from the blood (2, 3). Figure 2. Figure 1. The lymphatic vessels form a major element of the lymphatic system and are extensively distributed in most areas of the body excluding the central nervous system, bone marrow, bones, teeth, eyeball and avascular tissues
