How does venous return and heart rate affect exercise EDV? (a) Why might myocardial hypertrophy be good for an endurance athlete but bad for a hypertensive patient? (b) What does hypertension do to the heart? List two ways in which the autonomic nervous system (ANS) influences blood pressure...
How does the respiratory system maintain homeostasis during exercise? Does the environment affect how structures of the cardiovascular and respiratory systems work together to meet the demands of the body during rest and exercise? Explain how an individual can increase the unloading of oxygen f...
In mechanically ventilated patients, PEEP is used to keep alveolar pressure above the closing pressure of alveoli thereby maintaining end-expiratory lung volume (EELV) and arterial oxygenation. In another words, PEEP does not strictly induce alveolar recruitment but PEEP avoids alveolar derecruitment by...
whereas the combination of strength and aerobic exercise reduces the possibility ofcesarean sections. Sensible strength training, as well as aerobic, does not harm but even improve the health of both mother and child.
We added to the original scheme an arrow for venous return from the skin to body core and description of counter current heat exchange and convective heat transfer from core to the skin (Fig. 3). The advanced body temperature regulation observed in the tropical participants would be due to ...

Moreover, we need to know the long-term consequences of the above effects. In other words, we need to know if and how changes in the crucial biological processes mentioned above can increase the risk of acute and chronic disease onset and/or influence disease progression. ...
Exercise Machines that squeeze your limbs to improve circulation Special warming boots Doctors also are comparing drugs used to treat DVT. They want to learn whether some are more effective than others, and whether certain medications can help prevent DVT. They’re testing new drugs, too. How D...
Blood clots can form in veins (venous clots), interfering with the return of blood from tissues to the heart, or arteries (arterial clots), interfering with movement of oxygenated blood from the heart to tissues and organs throughout the body. A blood clot attached to a vessel wall is know...
The following week a consultant from my own ward took me aside and told me that what this professor had said to me in the lecture would have no influence on my future career. I resolved that it wouldn’t. I was miserable and it was contaminating my private life. Having turned into ...
