Answer:
When a person engages in physical activity, he undergoes aerobic situations where the heart muscle is optimally strained and improves its muscle strata.
There are scientific studies that compare the muscular walls of athletes and sedentary people, the walls of athletes are thicker and have more power when it comes to pumping and ejecting blood, that is, they make fewer contractions of the heart muscle but more effectively due to They eject more blood, while in unhealthy or sedentary people their muscles are weak, and they pump less blood into the torrent for each contraction, so they need to compensate for non-ejected blood volume by contracting more times and therefore increasing the heart rate.
Thus, physical activity generates a more effective contraction, which is why the heart rate of athletes is lower.
In the case of blood pressure, blood pressure is lower and there are no atheroma plaques or fatty tissue accumulation as in the case of sedentary patients.
Venous return in athletes is aided by contraction of the skeletal muscles of the lower limb, so cardiac filling is better and the heart has less energy demand (this does not happen with sedentary).
Explanation:
In summary, the heart rate is decreased by the great contractile power of each cardiac pump, the blood pressure is decreased by the low cardiac demand and by the good blood circulation, the venous return is favored by the contraction of the skeletal muscles of the Lower limb and myocardial walls are much thicker or hypertrophic due to good oxygenation and sports activation during physical activity.
Answer:
The best answer for the question: These data indicate a defect in which of the following? when talking about a patient who is able to absorb disaccharides, like maltose, fructose and lactose, but not complex polysaccharides, like starch, would be, D: Pancreatic enzyme secretion.
Explanation:
The importance of the pancreas for human nutrition, cannot be stated enough. It is this organ that is responsible for the secretion of the majority of the enzymes responsible for breaking apart the molecular unions of complex nutrients, such as starchs, fats, and proteins, to reduce them to their more basic units, so the body can absorb them and use them. If these pancreatic enzymes are either absent, or faulty, then complex nutrients cannot be broken down, regardless of what other enzymes might be working properly after. If the main chemical bonds of the molecules cannot be undone, then other enzymes cannot do their own work. Panceatic amylase is central for starch break up into smaller mono and disaccharide units, and from there, brush border enzymes in the small intestine take over to further break these into basic units that will be absorbed. In the case of this patient, amylase is probably absent, or is faulty, which is why he cannot absorb glucose from starch, but he can if he eats simpler foods with more basic sugars. This is why the answer is D.
Answer: False.
Explanation:
The main function of hemoglobin is to transport oxygen to the various cells of the body. For this process to occur the oxygen from the lungs gets attached to the hemoglobin and travels throughout the body to reach at every possible place.
This hemoglobin also gets attached to the carbon dioxide from various cells of the body to lungs for gaseous exchange.
There are many factors that affect the loading and unloading of oxygen from hemoglobin. The increased temperature increases the rate of unloading of oxygen from hemoglobin and increased temperature does not favors loading of oxygen to hemoglobin.
Hence, the given statement is False.
Answer:
B.With pillow between the legs.
Answer:
Plague doctor
Explanation:
They were doctors that offered services to people affected by the plagues then. They were sent specifically to areas affected by the plagues and paid by the government themselves. They helped to keep records of victims affected by the plagues too.
