Effect of Substances on the Heart Rate of a Daphnia Magna Lab Report Katherine Schmucker WCCC/Semester 2 A&P 2/Bio-072 Dr. Matthew Sisak February 6, 2015 Introduction: The substances that were applied to the Daphnia were aspirin, nasal spray, adrenalin, acetylcholine, and alka seltzer (College, p. 42). Aspirin’s active additive is acetyl salicylic acid (Henderson, n.d.). The nasal spray’s active additive is “therapeutic (Administration, 2002).” Adrenalin’s active additive is “acid tartrate

pathways. The parasympathetic nervous system is responsible in the “rest and digest” responses of the body, including the role of slowing down the heart rate and reducing the strength and output of each cardiac cycles, which causes the lowering of blood pressure. Neurons located in the spinal cord and medulla of the brain stem project closely towards their target organ to form a synapse, in which the neurohormone, acetylcholine, is secreted from the vagus nerve to the heart. Acetylcholine is an inhibitory

successful remission. Last month, she presented at her primary care provider with increased fatigue and shortness of breath. Initial blood tests showed reduced WBC and platelet count. Her PCP referred LV to the Colorado Blood Cancer Institute for further evaluation. The CBCI completed a bone marrow biopsy. The results were consistent with relapse. Their blood tests showed the following: WBC count, 2200 cells/mm3; Hgb, 6 g/dL; Platelets, 60,000/L; Albumin, 2.0 g/dL; Creatinine, 0.7 g/dL; Sodium

1. What are two types of medicine? How do the types differ from each other? What is an example of each? Curative medicine focuses on the individuals who are already ill or injured. It tries to restore an individual to normal functioning. Preventative medicine focuses on stopping illnesses from happening before they occur. For example, you would experience curative medicine when you go to the doctor for treatment for strep throat. If you have received a vaccine, you have experienced preventative medicine

The Xstat is a device that helps stop the bleeding from critical wounds, such as a gunshot wound. It was designed by a group called “Revmedx” from Oregon. The group consists of scientists and many combat veterans. The FDA announced and made it an official medical product on April 3rd, 2014. In the past, squad medics would have to use a gauze and bandages, along with applying direct pressure to stop the bleeding of a gunshot wound, and sometimes even that wouldn't work. With the XStat the bleeding

higher the BMI the higher the HR is going to rise without plateauing somewhere. This shown by Patrick and Nicole’s HR in the last trials of each exercise. Their HR would have kept increasing to a point where the heart can't keep up with the amount blood needed for the muscle. This investigation also proved the other hypothesis we had about the intensity of the level of exercise and it’s positive correlation with the HR. The HR increased substantially as the level of the exercise increased. This can

I chose to summarize this review article to understand the reasons behind exercising a patient with hypertrophic cardiomyopathy (HCM). Prior to the reading, my knowledge of stress echos only covered the bases of diagnosing coronary artery disease. This review focuses on the patient’s subjective complaints and its correlation with sudden death from HCM. It’s common for us to see patient with HCM and to perform Valsalva maneuvers to check for LVOT obstruction with increased velocities. However,

wastes, salt, and extra water from your blood. It also helps keep healthy mineral levels in your blood. It is done when your kidneys cannot keep your blood clean. During hemodialysis, your blood travels outside of your body to a machine (dialyzer). A filter in the machine cleans the blood. It is usually done 3 times a week. Visits last 3–5 hours. What happens before the procedure? You will need a procedure to make an opening (vascular access). This is where blood is removed and returned to the body.

In normal physiology, circulating endothelin helps maintain normal vascular tone. In PAH, levels are elevated in the blood stream and the capacity to clear endothelin from the circulation is reduced. Endothelin exerts its effects by activating two distinct receptors, endothelin A (ETA) and endothelin B (ETB) (Archer et al., 2010). These receptors mediate the pathophysiologic
