Answer:
The correct answer is option D. give furosemide.
Explanation:
Digoxin is a drug that uses in the cardiovascular condition. It inhibits the Na-K ATPase enzyme, which functions to maintain the intracellular environment by regulating the entry and exit of sodium and potassium.
Digoxin toxicity may occur due to the low level of potassium (inside the cell)due to the inhibitaion of the sodium-potassium pump. Furosemide is a diuretic drug that decreases salt concentration (such as ions) in the body by increasing urine output. and causes a low level of potassium in the body
Thus, furosemide increases digoxin toxicity as during low levels of potassium, digoxin can easily bind with the sodium-potassium pump and shows severe effects.
Answer: Blood loss regulation
Explanation:
Positive feed back is response of body in which there is an increase in the effect of small disturbance and the effect is intensified on a system. The magnitude of the effect increases.
In case of blood loss the body releases clotting factors that helps in preventing the body from severe blood loss.
The body releases clotting factors and these clotting factors tend to release more and more clotting factors that begins the process of blood clotting in vessels.
This is an example of positive feedback which acts as a life saving cascade.
Answer:
The correct answer is option B- pressure within the alveoli.
Explanation:
Intrapulmonary pressure is the pressure within the lungs especially in the alveoli of the lungs so is also known as "intra-alveolar pressure".
This pressure helps in the breathing process as :
1. During inspiration - The thoracic cavity volume increases due to which the intra-pulmonary pressure becomes less than the atmospheric pressure which causes the lungs to inhale about 500 ml of air.
2. During expiration- the thoracic volume decreases which cause the intra-pulmonary pressure larger than atmospheric pressure which causes the lungs to exhale the air.
Thus, option B- pressure within the alveoli is the correct answer.
Answer:
The growth hormone/IGF-1 system stimulates both bone-resorbing and bone-forming cells, but bone formation is the dominant effect, resulting in increased bone mass. Thyroid hormones boost the energy production of all cells in the body, including bone cells.
