Excessive secretion of aldosterone causes which of the following responses?
Increased plasma potassium
Increased plasma sodium
Decreased plasma phosphorus
Decreased plasma calcium
The Correct Answer is B
A. Excessive aldosterone causes increased reabsorption of sodium and water, and the excretion of potassium. Therefore, excessive aldosterone would typically decrease plasma potassium levels, not increase them.
B. Aldosterone stimulates the kidneys to reabsorb sodium and excrete potassium, leading to increased plasma sodium levels. This is the correct effect of excessive aldosterone secretion.
C. Phosphorus levels are not directly affected by aldosterone; its primary role is in regulating sodium and potassium balance.
D. Aldosterone does not directly regulate calcium levels in the blood, so plasma calcium levels are not significantly affected by aldosterone secretion.

A. The thyroid gland functions only as an endocrine gland. It secretes hormones like thyroxine (T4) and triiodothyronine (T3) into the bloodstream, but it does not have an exocrine function.
B. The pituitary gland is an endocrine gland that secretes hormones into the bloodstream but does not have exocrine functions.
C. The hypothalamus is involved in hormone production and regulation but is considered part of the brain rather than an endocrine or exocrine gland itself.
D. The pancreas functions as both an endocrine and exocrine gland. It produces insulin and glucagon (endocrine functions) and secretes digestive enzymes into the small intestine through ducts (exocrine function).
Correct Answer is C
Explanation
A. Oogenesis is the process of egg cell (ovum) formation in females and is responsible for producing gametes, not somatic cells.
B. Spermatogenesis is the process of sperm cell formation in males, also producing gametes, not somatic cells.
C. Mitosis is the process that produces somatic cells. It is a type of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell. Somatic cells are all body cells except for gametes.
D. Meiosis is the process that forms gametes (sperm and eggs), reducing the chromosome number by half to ensure sexual reproduction results in a normal chromosome count. It does not form somatic cells.
