Answer:
a. Proximal convoluted tubule is responsible for reabsorbing most part of the ultrafiltrate. This means that at this level, substances like glucose and amino-acids are reabsorbed almost completely throughout this tube. Other substances, like potassium and bicarbonate are also reabsorbed in a big percentage here.
Also depending on the organism needs to keep the water balance, sodium, chloride and water are reabsorbed partly.
b. If the glucose transport is exceeded in the PCT, glucose will pass to the filtrate. Given the fact that glucose is osmotically active, high concentrations of glucose not being reabsorbed will consequently 'drag' water along. This situation ends up in an increase urine volume.
When diabetes mellitus is not controlled, patients will experience high volume of urine. Meaning they feel the need to go to the toilet very often. Also there is presence of glucose in the urine, which is normally not there.
c. The nephron loop is designed so the urine can be concentrated, saving water. The TCP is connected to the descending limb of the nephron loop, which is very permeable to water but not to other solutes like ions and urea. Then the following ascending limb of the loop, is not permeable at all to water, but ions can be reabsorber, especially cations. Therefore in a non pathological situation. This mechanism enables the production of concentrated urine when needed to save water and more diluted urine if there was a need to excrete water.
Answer:
i think the most difficult part about communicating using medical terminology is
- 1. knowing and remembering the correct words in the medical terminology.
- 2. if you're a doctor and you're talking to a patient you can't be speaking in medical terms. you have to speak to them with words they would be able to understand .

Answer:
With respect to the anterior pituitary gland, it is true that it is often referred as the "master gland" of the endocrine system (option C).
Explanation:
The pituitary gland —also called hypophysis— divided into two parts, an anterior part called the adenohypophysis and a posterior part called the neurohypophysis.
The adenohypophysis or anterior pituitary gland is in charge of the secretion of hormones that serve to regulate the hormonal secretion of other glands, such as the thyroid, the suprarenal glands and the gonads. This is the reason why it is considered and often referred as the "master gland" of the endocrine system.
The neurohypophysis depends on the control of the hypothalamus and the neurotransmitters that this structure sends to the pituitary, releasing hormones whose effect is direct on the target organ.
The other options are not correct because:
<em> A. Anterior pituitary does not </em><u><em>release hormones made by the neurons in the hypothalamus</em></u><em>.
</em>
<em> B. Adenohypophysis has </em><u><em>hormone-producing cells</em></u><em>.
</em>
<em> D. The anterior pituitary is </em><u><em>not regulated by the hypothalamus and is considered part of the endocrine system</em></u><em>.</em>
Answer:
The correct answer is b. CRH
Explanation:
CRH (Corticotropin-releasing hormone) is released by hypothalamus gland in stress condition. After it's release it reaches to the pituitary gland and initiate the secretion of ACTH (adernocorticotropic hormone).
ACTH then stimulate the secretion of steroid hormones from adrenal cortex. Secretion of steroid hormone like cortisol are essential in fight and flight response under stress condition. This whole path is known as HPA(hypothalamic-pituitary-adrenal) axis.
So the correct answer is b. CRH
