Question

68) As you go from the cortex to the outer medulla and to the inner medulla the interstitial solute concentration_______

1. Increases
2. Stays about the same
3. Decreases
4. None of these

69) Osmoregulation involves the Homeostasis of the

1. Blood platelets
2. Brain tissue
3. Water and solutes inside the body of an animal
4. Red blood cell number

Use the next 5 answer choices for the next seven questions (some questions require you to mark two answer choices on your scantron)

A) Antidiuretic hormone (ADH)

B) Adrenocorticotropic hormone (ACTH)  

C) Glucagon

D) Insulin

E) Thyroxin

70) Which controls the rate of cellular Metabolism?

71) Which is involved in controlling long term responses to stress?

72) Which causes glucose to be released from tissues into the blood

73) Which causes glucose to be taken from the blood and stored by tissues as glycogen?

74) Which are synthesized by the Pancreas?

75) Which controls water uptake in the luminal epithelium of the nephron’s collecting duct?

76) ADH is water soluble so requires

1. a G-Protein coupled receptor to transduce the signal through the membrane for cAMP signaling
2. a blood transport protein to travel through the circulatory system
3. hormone targets inside the cell’s nucleus

77) Estrogen and testosterone are fat soluble hormones so do NOT need

1. targets in the nucleus of the cell
2. blood transport proteins
3. a G protein coupled receptor for signal transduction

78) ADH causes

1. The nephron to conserve water by reabsorption
2. The nephron to lose water by expelling it in the urine

79) Which releases ADH into the blood?

1. The Hypothalamus
2. The Medulla Oblongata
3. The Pituitary
4. The adrenal glands

Answer 1

It increases . Kidney expends energy as it macimises diffusion of slat put of the tubule

Water and solutes inside the body of an animal . Homeostasis is a balance that helps all key processes of the human body to function in coordination with each other.

• thyroxin controls the rate of cellular metabolism . When its conc increases the rate of metabolism increases and vice versa
• ACTH is involved in long term repsonse to stress via cortisol hormone
• Insulin helps in glucose absorption and utilisation and if not then storage
• Insulin and glucagon
• ADH and then it causes less urine output.

Adh acts throug option 1 - G protein couples receptors which transduce the signal theough the membrane for cAMP signalling

adh - nephrons conserve water by reabsorption. It acts on DCT to do that

The pituitary . ADH is produced by hopthalamus in the brain and them the posterior pituitary stores it and releases it when it receives the requisite signal
