1. This is part of the heart that is under the simplesquamous epithelium, fibroelastic connective tissue and some smoothmuscles. This is where modified cardiac muscles arelocated.

2. These are structures made up of dense irregularconnective tissue that acts as insulator for the flow of electriccurrent across the heart, surrounds the cardiac valves, and wherethe ventricular and atrial muscles are inserted.

3. These are modified cardiac muscle that are palestaining, smaller with fewer myofibrils and intercalated discs thanthe regular cardiac muscle and located in the right atrialwall.

4. What tissue within the vascular wall which is the keyin regulating blood pressure.  

5.This is a part of the blood vessel consisting of asingle layer of squamous cells, loose connective tissue andsometimes few smooth muscle cells.

6. This is a collective term that refers to thecapillaries, arterioles and venules in the outer part of the largeblood vessels.

7. These are cells that surrounds the capillaries whichcontains dopamine, acetylcholine, and other neurotransmitters. Itcontains ion channels that responds to low oxygen and high carbondioxide levels in the arterial blood.

8.These are blood vessels whose walls contains a singlelayer of squamous cells, 2 layers of smooth muscle cells, and anouter layer of thin connective tissue. It is the major determinantof the systemic blood pressure.

9.This is part of the circulatory system wherein thearterioles connect directly to venules. It is richly supplied bysympathetic and parasympathetic nerve fibers.

10. These are structures in the circulatory system thatallows blood to flow into the capillary bed in a cyclicalmanner.
