Answer: Option B. "False"
Explanation:
Nephron can be defined as the functional unit of the kidney.
Descending limb and ascending limb are the combinly called loop of nephron or henle and are the part of renal tubule in the nephron.
Descending limbs and ascending limbs have different permeabilities to water and salt that causes high osmolarity in the Medulla.
The thin descending limb is having high permeability to water as they have low permeability to ions and urea while the thick ascending limb has impermeablity to water as there is active reabsorption of ions.
Hence, the correct option is B.
Answer:
The correct answer will be option- C.
Explanation:
Dehydration is the loss of water from the body in the response to which body undergoes physiological and metabolic changes as:
1. The hypothalamus produces Anti-diuretic hormone or ADH from the posterior of the pituitary gland which produces its effect on the kidney to reabsorb the water.
2. The body produces renin, angiotensin II and aldosterone which increases the permeability of the distal convoluted tubule and the collecting ducts.
3. The extracellular blood or the blood becomes more concentrated due to dehydration.
Thus, option- C which is that renal tubules decrease water reabsorption is the incorrect option as water absorption is increased in the kidney.
Answer:
Delegatee Responsibilities
Everyone is responsible for the well-being of patients. While the nurse is ultimately accountable for the overall care provided to a patient, the delegatee shares the responsibility for the patient and is fully responsible for the delegated activity, skill or procedure
Greater decreases in overall brain volume in later adulthood is associated with an unclear exact relationship in cognitive abilities and cognitive functioning.
<h3>How brain changes in late adulthood?</h3>
The brain's size reaches roughly 90% of its adult volume by the time a child is six years old. The brain begins to contract in our 30s and 40s, and by the time we reach our 60s, the brain is contracting even more rapidly. The brain begins to change in appearance, just like wrinkles and gray hair do later in life.
The brain actually shrinks and its overall mass decreases as adults. There are decreases in some neurotransmitters as well, including dopamine and acetylcholine. Loss of memory for recent events, familiar names, and familiar duties is the first sign of Alzheimer's disease. In old age, general knowledge memory does not deteriorate. There has been a deterioration in episodic and event memory.
