AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Structure of the Heart**: The human heart is divided into four chambers. These chambers are categorized into two types: atria (upper chambers) and ventricles (lower chambers). 2. **Identifying the Chambers**: The heart consists of two atria (right atrium and left atrium) and two ventricles (right ventricle and left ventricle). 3. **Focusing on the Lower Chambers**: Since the question specifically asks for the lower chambers of the heart, we need to identify which of the four chambers fall into this category. 4. **Naming the Lower Chambers**: The two lower chambers of the heart are called the ventricles. Therefore, the answer to the question is "ventricles." **Final Answer**: The lower chambers of the heart are called ventricles. ---

Left ventricle is the thickest chamber of the heart.

What is the number of chambers in the heart of periplaneta americana ?

Oxygen-rich blood from the lungs comes to the thin-walled upper chamber of the heart on the left. The left upper chamber (A) then relaxes. It then contracts and the blood is allowed to enter the next chamber (B), as it expands. When the muscular left lower chamber of heart contracts the blood is pumped out to the body via aorta. Deoxygenated blood reaches from the body to the upper chamber on the right side of heart (C) and it expands. As this part contracts, the corresponding lower chamber (D) dilates. This transfers the blood to right ventricle, which in turn pumps it to the lungs for oxygenated. Which chambers of human heart contain oxygenated blood?
