Answer:
The answer to the question: velocity of blood is relatively constant as blood flows from the aorta towards the capillaries, would be, B: False.
Explanation:
One way to figure this one out is knowing that the velocity of the blood as it flows through the aorta, comes from the pumping strength of the heart. However, as the blood starts traversing the length of the different arteries, arterioles, and finally reached the capillaries, it encounter two things; first, the speed with which it was originally launched by the heart into the aorta, has already diminished as it moves away from the heart. Second, blood will encounter a series of barriers, not the least of which is resistance from the blood vessels themselves, that will lower the speed with which it will reach the capillares. And this is just as well, as capillaries are much more fragile than arteries themselves, their purpose actually being to serve as exchange points between the cardiovascular system and the different tissues of the body. Their structure is much thinner, and thus needs less speed, in order for exchanges to take place. This is why it is false.
Answer:
The correct answer to this question: A nurse is teaching a client about nitroglycerin sublingual tablets. Which of the following statements by the client indicates an understanding of the teaching?, would be: B: "I should take this medication as soon as pain begins."
Explanation:
Nitroglycering sublingual tablets, also known commercially as Nitrostat, are a type of medication used to help by reducing the tension in blood vessels on people who have certain heart conditions, like coronary artery disease. Essentially, when a person feels pain in the chest (angina), or knows it will happen because there will be exercise, caused by the increase in blood vessel tissue tension, which limits the flow of blood to the heart, they must take the tablet and place it under the tongue as soon as the pain sets in, while in the case of exercise, they should take the medication at least 10 minutes before the initiation of exercise. So, this is why, the answer is B, because it shows that the patient understood that as soon as he feels pain, he must take the tablet.
Answer:
Catabolism is method by which large complex molecules like lipids, proteins and carbohydrates are broken down into the simpler smaller molecules.
Protease or peptidase are the enzymes that catalyzes the breakdown of proteins into amino acids or smaller polypeptide units. The protease enzyme pepsin is secreted in the<u> stomach</u>; and trypsin and chymotrypsin is secreted in the<u> pancreas.</u>
Amylases are the enzymes that breaks down the complex carbohydrates to simple sugars. The enzyme salivary amylase is secreted by the <u>salivary gland in mouth</u> and the enzyme pancreatic amylase is secreted by <u>pancreas.</u>
Lipases are the enzymes that catalyzes the breakdown of lipids or fats. Lipases are secreted in the <u>mouth, stomach, and pancreas.</u>
