Danielle Rollins Cardiovascular Physiology Activity 1 1) Explain why the larger waves seen on the oscilloscope represent ventricular contraction. The ventricular contraction is when the blood is sent through the whole body as opposed to the atrial contraction that sends the blood to the heart and lungs. 2) Explain why the amplitude of the wave did not change when you increased the frequency of the stimulation. (Hint: relate your response to the refractory period of the cardiac action

Review Sheet Results 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Your answer: If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare

The Renal Diet 1.The kidneys: * The kidneys are a pair of bean-shaped organs that lie on either side of the spine in the lower middle of the back. Each kidney weighs about ¼ pound. * It is important to keep the kidneys in good working order to allow them to work at an optimum level. * The main function of the kidneys is to remove waste products and excess water from the blood. The kidneys process about 200 l’s of blood every day and produce about 2 l’s of urine. * The kidneys

Renal calculi literally translates to kidney stones. These kidney stones form inside your kidneys but can affect your entire urinary tract as it travels (which includes the bladder‚ urethra‚ and ureters.) Stones form when urine is too rich with minerals and salts causing them to stick together creating a small‚ hard‚ pebble-like sediment. Kidney stones are a collection of proteins and mineral salts that aggregate into a solid crystalline structure. The stones structure is made of two phases‚ crystalline

from 40 to 19.7 because the body was getting rid of CO2 by hyperventilating. 8. If you observed an acid/base imbalance during this run‚ how would you expect to renal system to compensate for this condition? The renal system would generate H+ and excrete HCO3- to counteract the respiratory system and lower the pH back to homeostasis. 9. How did the hyperventilation trace differ from the trace for the normal breathing? Did the tidal volumes change? The tidal volume and the rate increased drastically

LAB ONE: Exercise 4 – Endocrine System Activity 1: Metabolism and Thyroid Hormone Part 1: 1. The normal rat had the fastest basal metabolic rate. 2. The metabolic rates differed between the normal rat and the surgically altered rats because the surgically altered rats didn’t have a thyroid or pituitary gland and therefore‚ the normal rat had a faster basal metabolic rate. The results turned out to be the way I predicted them to be. 3. T3 and T4 would be missing in the animal’s blood
