Blood flows directly from the left atrium to ________.

  1. a. the aorta
  2. b. the left ventricle
  3. c. the right atrium
  4. d. the pulmonary arteries

Summary Introduction

Concept introduction: The heart is a muscular pumping organ composed of two atria and two ventricles. Transport of blood to different body parts is done by the effective pumping of the heart. It provides functional supply of oxygen and all other essential nutrients to all body parts. Based on the path of blood circulation, it has been classified into systemic and pulmonary circulations.

Explanation

Reason for the correct answer: The blood circulation inside the heart always follows a common root. It starts from the flow of deoxygenated blood to the right atrium and then draining to the right ventricle. Then, from the right ventricle, the blood goes for oxygenation to the lungs; from lungs, it goes to the left atrium and then to the left ventricle. Finally, the oxygenated blood in the left ventricle will be pumped into the largest artery, the aorta. Numerous small arteries arising from the aorta will carry the blood to different body parts.

Option b. is given as “the left ventricle”. Oxygenated blood entering the right atrium will move to the left ventricle and from there, it goes to the aorta. Therefore, option b. is the correct answer.

Reason for the incorrect answers:

Option a. is given as “the aorta”...
