Explain left auricle and left ventricle in brief
Answers
Answer:
The left ventricle is the thickest of the heart's chambers and is responsible for pumping oxygenated blood to tissues all over the body. By contrast, the right ventricle solely pumps blood to the lungs.
The left auricle, also known as the left atrial appendage (LAA), is actually a small, muscular pouch at the upper corner of the left atrium. It collects oxygenated blood as it leaves the lungs and moves the blood into the left ventricle.

→ Circulation is an important aspect of living organisms.
→The presence of a circulatory system in living organisms ensures the transportation of essential elements throughout the body.
→ The human circulatory system possesses a heart as the pumping device.
Auricle
The upper chamber of the heart where blood is entered is referred to as auricle or atrium. The human heart possesses two atria, left atrium and right atrium. The two atria are separated into the left atrium and right atrium by a muscular wall at the medial edge of the right atrium.
Ventricle
The lower chambers of the heart are ventricles. Similar to auricles, ventricles are of two types, the left ventricle, and the right ventricle. Both left and right ventricles are equal in size. The left ventricle in comparison with the right ventricle is longer and provides a conical shape to the heart. The walls of the left ventricle are thicker than the walls of the right ventricle in order to withstand the pressure since it involves in pumping blood throughout the body
