What tissue is the heart and blood vessels lined by?

simple squamous epithelium

What are the four main tissue categories?

(1) Muscle Tissue (2) Connective Tissue (3) Neural Tissue (4) Epithelial Tissue

Close examination of a healthy organ reveals a lining of several layers of cells. The layers do not contain any blood vessels and one surface of the cells lines the cavity of the organ. What type of tissue is this?

hyaline cartilage

To celebrate her 50th birthday, Anna got her ear pierced in the elastic cartilage portion (pinna). The piercing specialist informed her that it will take at least 6 weeks to heal. Why is this?

cartilage is avascular, so healing takes longer.
