Answer:
a. Diameter of afferent astride is bigger than efferent arteriole to generate force for efficient filtration
b. Urine is slightly thicker in summer than in winter to reduce water loss from the body
c. Always vasopressin is not secreted when a person drinks sufficient water
d. ESRD stands for End stage renal disease
Explanation:
a. While transferring blood from afferent astride to efferent arteriole blood gets filtered. Filtration is efficient when the blood flows with force which is generated when blood flows from large arteriole to the small arteriole. Hence the diameter of afferent astride is bigger than efferent arteriole.
b. Urine is slightly thicker in summer than in winter to reduce water loss from the body. In summer water is lost in the form of sweat as well. Hence, urine gets concentrated to compensate for the lost body fluid.
c. Always vasopressin is not secreted when a person drinks sufficient water. The osmoregulation is maintained externally.
d. ESRD stands for End stage renal disease
<span>The respiratory system deals with the body's breathing system, including the mouth, throat and lungs. An example of something the respiratory system doesn't do is anything with the digestive system. The digestive system consists of the mouth, throat, stomach, intestines and colon. It processes food and liquids into nutrients and energy for the body.</span>
Cancer or any number of other genetic mutations like diabetes, birth defects, etc.
D: After many experiments and much more data has been collected.
