Blood, Nutrients, Oxygen and other gases, and hormones to the cells and from the cells are the responsibility of the circulatory system.

Answer to Problem 8STP

Correct answer:

The correct answer is option (B) four-chambered heart, two circulatory loops.

Explanation of Solution

Explanation/justification for the correct answer:

Option (B) four-chambered heart, two circulatory loops. The human circulatory system consists of a four-chambered heart and two circulatory loops. The blood flows through the four chambers of the human heart. The four chambers are right and left atrium and right and left ventricle. And The two chambers are pulmonary and systematic loop. The pulmonary loop transfers deoxygenated blood to the lungs from the right side of the heart and the systematic loop transports oxygenated blood from the left ventricle of the heart. So, this is the correct option.

Explanation for incorrect answer:

Option (A) four-chambered heart, one circulatory loop. The human circulatory system consists of a four-chambered heart and two circulatory loops. So this is an incorrect option.

Option (C) two-chambered heart, one circulatory loop. The human circulatory system consists of a four-chambered heart and two circulatory loops. So, this is an incorrect answer.

Option (D) two-chambered heart, two circulatory loops. The human circulatory system consists of a four-chambered heart and two circulatory loops. So, this is an incorrect answer.
