The size of a stone crab claw is considered to be the length of the propodus. The propodus is the larger, immovable part of the claw. Legal-sized (harvestable size) claws are 70 mm (2 3/4 inches) or greater in propodus length.
Blood is called a connective tissue because it carries with it many digestive substances, oxygen from lungs, foods from small intestines and provide it to other tissues and organs of the body.
Arteries. Arteries carry blood which is full of oxygen away from the heart. Arteries have three layers of tissue-the outside and inside layers are made of a connective tissue which covers the muscular middle layer of smooth muscle, and elastic fibers.These tissues provide a smooth path for our blood to flow through.hey explain that healthy arteries are made of muscle and a semi-flexible tissue that stretches like elastic when the heart pumps blood through them. The more forcefully that blood pumps, the more the arteries stretch to allow blood to easily flow.
