Bio 249 Physiology Exam 5 Study Guide V 0 Pre Course Study Questions And Answers 100% Correct.

Blood flow can be quantified in "mm/s" units. T/F - correct answer False Myogenic control is a process that allows arterioles to vasocontrict to reduce blood flow. T/F - correct answer True There is a net movement of water from the capillaries to the interstitial spaces. T/F - correct answer True By increasing blood volume, blood pressure will increase as well. T/F - correct answer True Pulse pressure is calculated as diastolic pressure - the systolic pressure. T/F - correct answer True Blood velocity is the slowest in the capillaries because that is where blood pressure is the lowest. T/F - correct answer True Adaptive immunity has "memory" of past infections because of lymphocytes. T/F - correct answer True The innate immune responses can be enhanced by antibodies made by the adaptive immune response. T/F - correct answer True Macrophages can be antigen-presenting cells (APCs). T/F - correct answer True A mucous membrane is considered part of the adaptive immune response since it can dynamically change mucus production. T/F - correct answer True Plasma stores a vast majority of oxygen in the bloodstream. T/F - correct answer False Increased ventilation will reduce the concentration of carbon dioxide in the blood. T/F - correct answer True Bicarbonate ions (HCO3-) is considered the pH buffer in blood. T/F - correct answer False According to Boyle's law, when there is an increase in volume, there is a proportional increase in pressure. T/F - correct answer False As a person grows and their airways grow in the length, the resistance to airflow will increase as well. T/F - correct answer True As resistance to airflow increases, airflow through the lungs will increase. T/F - correct answer False If the total peripheral resistance increased, what would happen to the mean arterial pressure? - correct answer it would increase If the contractility of the heart decreased, what would happen to the mean arterial pressure? - correct answer it would decrease Which will have a greater effect on mean arterial pressure? - correct answer Increased diastolic pressure Where would blood flow be the lowest in the systemic ciruit? - correct answer Capillary beds in the stomach Where are the baroreceptors found in the systemic circuit? Note: Select all correct answer choices. - correct answer Aorta Carotid Arteries Which of these events will increase the total peripheral resistance? Note: Select all the correct answer choices. - correct answer Blood vessels have lengthened during body growth. Blood viscosity has increased from eating a meal. You are the medical office and the absent-minded nurse takes your blood pressure using the pressure cuff. They pressurize the cuff and restrict blood flow in your arm. The nurse forgot their sandwich in their car and immediately runs off to get it. The pressure cuff is still on you and pressurized. How will your body respond to blood flow being restricted? Assume the cardiac control centers are sensitive to changes in blood flow in your arm. - correct answer Total peripheral resistance will decrease Puff Daddy drank too much of his own product, Ciroc, and now his Alcoholic Cihorsis (pun intended). Now, his liver doesn't make a plasma protein called Albumin. Albumin is an actively osmotic protein in high abundance in the plasma of blood and helps create the colloid osmotic pressure. Because of his condition, how will P. Diddy's blood volume change? - correct answer His blood volume will decrease Why does arterial blood pressure vary over time? - correct answer Artery walls are elastic and can stretch and recoil Put the following blood vessels in the highest to lowest blood pressure order: - correct answer i. ii, iii Count Strahd von Zarovich realizes you're the latest incarnation of Tatyana, his consort from another lifetime. In a frenzy, he lunges for your neck and drinks deeply in your blood. Other than becoming a vampire, soon you have lost a lot of blood volume. For now, you live as a human and still have functioning human physiology. Initially, how will this affect your blood pressure, and what is one way your body will react to compoensate? - correct answer Your blood pressure will decrease, but our heat will beat faster to increase cardiac output Arterioles can respond to local demands in blood flow. If receptors in the arteriole wall detect an increase in carbon dioxide concentration and a decrease in oxygen concentration, how will it respond? - correct answer Dilate to create greater blood flow As heart contractility goes up, how will it affect blood pressure? Note: Select all the correct answer choices. - correct answer Mean arterial pressure will increase. Systolic pressure will increase. Skin and mucous membranes are effective first lines of defense against pathogens because: - correct answer They act as physical barrier that blocks physical entrance of the pathogen. Memory cells stay in the body for a long time and they eventually produce the secondary immune response if the body is exposed to same triggering antigen. What is the difference between the secondary immune response and the primary immune response? Note: Select all correct answer choices. - correct answer It can last for years. It happens faster. It happens with a greater intensity What benefit can antibodies have in fighting pathogens? Note: Select all the correct answer choices. - correct answer Neutralization of infectious agent Stimulus of phagocytosis Agglutination/Precipitation Stimulus for inflammation Dr. Nair has developed antibodies for the Snow Crash virus. He will siphon his blood to collect those antibodies and administer them to his students who want it. What kind of immunity is Dr. Nair conferring to his students? - correct answer Artificial passive immunity Which of these cells are considered phagocytes? NOTE: Select all correct answer choices. - correct answer Macrophages Neutrophils Monocytes During the initial injury, mast cells react by secreting numerous chemical signals. What do these chemical signals directly trigger? Note; Select all cor
