Inner lining of Blood vessels and heart is tessellated Epithelium. This is also known as endothelium. The correct option is "A" which is simple squamous with a wavy appearance.
Explanation:
• The inner lining of blood vessels and heart is made up of a thin layer of flat cells known as endothelium or tessellated epithelium.
• The endothelium is composed of simple squamous epithelium that lines the lumen of blood vessels and the heart.
• The cells of endothelium are flattened and elongated, and they form a continuous layer.
• The cells of endothelium have a wavy appearance due to the presence of cytoplasmic extensions that overlap each other.
• These extensions are known as microvilli, which increase the surface area of the cells and help in the exchange of materials between the blood and tissues.
• The endothelium serves as a barrier between the blood and the underlying tissues.
• It regulates the exchange of nutrients, gases, and wastes between the blood and the tissues.
• The endothelium also plays a key role in the regulation of blood flow and blood pressure.
• It produces and releases various vasoactive substances that regulate the contraction and relaxation of blood vessels.
Therefore, option A is the correct answer which states that the inner lining of blood vessels and heart is made up of simple squamous epithelium with a wavy appearance.

The correct answer is option 'A' which states that the inner lining of blood vessels and heart is a simple squamous epithelium with a wavy appearance.
Explanation:
The inner lining of blood vessels and heart is called the endothelium. It is a thin layer of cells that form a continuous lining throughout the circulatory system. The endothelium is made up of a single layer of cells called endothelial cells, which are a type of epithelial cell.
The endothelial cells of the endothelium are simple squamous epithelial cells, which means that they are flat and thin cells. They have a wavy appearance because they are constantly being stretched and contracted as blood flows through the vessels. This wavy appearance allows the endothelium to expand and contract without tearing or rupturing.
The endothelium is also tessellated, which means that the cells are tightly packed together like the tiles of a mosaic. This tessellation helps to create a smooth and continuous surface for blood to flow over, reducing friction and preventing the formation of blood clots.
Conclusion:
In conclusion, the correct answer is option 'A' which states that the inner lining of blood vessels and heart is a simple squamous epithelium with a wavy appearance. This endothelium is tessellated, which helps to create a smooth and continuous surface for blood to flow over.
