Explain how CO interacts with the circulatory system, especially the relationship among CO, CO2, and O2 in blood cells and how exposure to CO influences normal oxygenation mechanisms. (b) Why are individuals with heart disease at greater risk when exposed to elevated CO levels?

. Nicotine, one of the components of cigarettes, slows cilia" lining the respiratory tract, causes blood vessels to con­strict, and increases heart rate. Another component of cigarette smoke is carbon monoxide. As you have read, carbon monoxide competes with oxygen for binding sites on the hemoglobin molecule found in red blood cells. Analyse the data presented, and describe the potential dangers associated with smoking.

Considering the nature of negative-feedback control and the function of the respiratory system, what effect do you predict that a decrease in CO2 in the internal environment would have on how   rapidly and deeply a person breathes?

Explain in a few sentences what the effects are of cryotherapy on the blood vessels. How can that be used to help with an acute injury?

All of the statements are true except A)Decreasing levels of oxygen in the blood are detected by chemoreceptors in the kidney. B)As a person's activity level increases, the level of CO2 in the blood increases and stimulates faster breathing. C)Chemoreceptors involved in the control of breathing are located in the brainstem and the carotid and aortic bodies. D)Breathing is controlled by both voluntary and involuntary mechanisms.

Pulmonary edema related to heart failure is caused primarily by which mechanism?   Question 2 options:   Left to right cardiac blood shynting via ventricular septal defect   Increased pulmonary capillary blood pressure   Initiation of the inflammatory response   Hypoxic injury to the alveolus

Which of the following combinations would all result in an increase in stimulation to breathe? Group of answer choices decrease in PCO2 : increase in H+ : decrease in PO2 increase in PCO2 : increase in H+ : decrease in PO2 decrease in PCO2 : decrease in H+ : decrease in PO2 increase in PCO2 : decrease in H+ : increase in PO2 decrease in PCO2 : decrease in H+ : increase in PO2

Listed below are cellular adaptations to altitude stress. All are correct except...     Increased 2,3-DPG concentration   Increased myoglobin    Remodeling of capillary diameter and length   Reduced microcirculation

Put the structural components provided in the order that an oxygen molecule travels by matching them with numbers 1-5.  (Not all structures will be used.) Left ventricle, aorta, left atrium, right ventricle, right ventricle, alveolus, cell, right atrium

Based on further discussions with Paul and conducting some literature research, Singh understood that sufficient cardiac output is vital in maintaining normal body function due to sufficient tissue perfusion and oxygenation. Therefore, the respiratory system is intimately linked to the cardiovascular system. He noted that two factors that affect the respiratory exchange of gases are the changes to blood flow and the surface area of alveoli. In addition, he learned that to meet the high metabolic oxygen needs of a newborn, the myocardium contractility is at its maximum. In addition, the myocar- dium is less compliant due to the disorderly organization of the higher amount of non-contractile proteins compared to
