Thin filaments
What is actin?
Atrioventricular valve with 3 flaps
What is the tricuspid valve?
A usually translucent somewhat elastic tissue that composes most of the skeleton of vertebrate embryos and except for a small number of structures (as some joints, respiratory passages, and the external ear) is replaced by bone during ossification in the higher vertebrates.
What is cartilage?
Attachment site that moves

Blood vessels with the thickest middle layer
What are arteries?
Translucent bluish white cartilage consisting of cells embedded in an apparently homogeneous matrix, present in joints and respiratory passages, and forming most of the fetal skeleton
What is the hyaline cartilage?
dense fibrous tissue that connect muscle to bone
What is a tendon?
