Question

Jeff Iliff says that the "biology that we observe can be thought of as a series of problems and their corresponding solutions." What is the brain’s first problem and how does the circulatory system solve it?

A. The brain's first problem is oxygen supply, and the circulatory system solves it by delivering oxygen-rich blood through the bloodstream.
B. The brain's first problem is temperature regulation, and the circulatory system solves it by circulating cooled blood throughout the brain.
C. The brain's first problem is waste removal, and the circulatory system solves it by transporting waste products away from the brain.
D. The brain's first problem is nutrient absorption, and the circulatory system solves it by facilitating the uptake of essential nutrients by brain cells.

Answer 1

The brain's first problem is the supply of oxygen, which is solved by the circulatory system delivering oxygen-rich blood through blood vessels, crucial for maintaining neurological function.

Step-by-step explanation:

Jeff Iliff suggests that the biology we observe is a result of problems and their solutions. The brain's first problem is supplying itself with oxygen. The circulatory system solves this problem by delivering oxygen-rich blood through an extensive network of blood vessels. A constant blood supply is crucial for the brain's function, as it needs oxygen and glucose to maintain its electrical activity. Without this steady supply, neurological function can be compromised. The heart and the blood vessels work together to ensure that the brain receives an uninterrupted flow of nutrient-rich and oxygenated blood, thereby maintaining homeostasis and proper function of the central nervous system (CNS).
