Electrical Stimulation Activity 1: Direct Heart Stimulation 1. Did you see any change in the trace? No change in the trace 2. Why or why not? This is because it needs more simulation 3. Did you see any change in the trace? I did see a change in the trace 4. Why or why not? There is double stimulation 5. Describe the change you see in the trace. How does it differ from the baseline trace? The trace increased from the baseline trace 6. What effect do the repeated stimuli

PhysioEx – Exercise 9 Activity 1: 1. excretion and regulation 2. glomerular capillaries (glomerulus) & Bowman’s capsule 3. The filtrate flows from the Bowman’s capsule into the renal tubule called the proximal convoluted tubule then into the loop of Henle‚ and finally into the distal convoluted tubule: a. Proximal Convoluted Tubule b. Loop of Henle c. Distal Convoluted Tubule 4. When the radius of the afferent arteriole was decreased‚ the pressure and the filtration rate both decreased

At 40 seconds‚ pH = 7.4 3. At 60 seconds‚ pH = 7.4 4. Did the pH level of the blood change at all during normal breathing? If so‚ how? No‚ it stayed at 7.4 5. Was the pH level always within the “normal” range for the human body? Yes 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No‚ it stayed at 40mm Hg Activity 2a: Hyperventilation – Run 1 1. At 20 seconds‚ pH = 7.43 2. At 40 seconds‚ pH = 7.52 3. At 60 seconds‚ pH = 7.67

through the 20 MWCO membrane? How well did the results compare with your prediction? Since the chemical formula for urea is (NH2)2CO and its molecular weight is about 60. It will not diffuse through the 20 MWCO membrane because it does not ionize. 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? Glucose will diffuse through the 200 MWCO membrane because its MW is 180. The MW of the protein

Skeletal muscle fibers are innervated (stimulated) by c. motor neurons. 2. A single action potential propagating down a motor axon results in d. a single action potential and a single contractile event in the muscle fibers it innervates. 3. In resting skeletal muscle‚ calcium is stored in c. the sarcoplasmic reticulum. 4. During the latent period

Assignment 1. 1. Summarise the main development of a child from the age range 0-2 years‚ 3-5 years and 5-8 years. 0-2 Years Newborn babies grow extremely quickly. During ‘Infancy’‚ which lasts from birth to eighteen months‚ babies change from a helpless newborn‚ to a child who can lift up their own head at three months‚ sit up unsupported at six months‚ walk at sixteen months and kick and throw a ball at two years old. Newborn babies actually lose some of their birth weight to begin with
