What structure of the heart is responsible for holding together adjacent cardiac muscle cells of the heart?
Pericardium
Desomosomes
Gap Junctions
Sarcomeres
Gap junctions are very important structures found within the heart. Which of the following DOES NOT apply to gap junctions.
Gap junctions allow ions to travel from one cardiac muscle cell to the next
Gap junctions are found in intercalated discs
Gap junctions are pores or openings between cardiac muscle cells
Gap junctions allow the four chambers of the heart to contract at the same time
What is the role of the sarcoplasmic reticulum found in cardiac tissue?
It releases sodium and potassium to help produce an action potential
It regulates the pace of the heartbeat
It releases ATP to power the cross bridge cycle
It stores and releases calcium into the sarcomeres
Which of the following statements is ALWAYS true

Which of the following applies to elastic arteries
They transport deoxygenated blood
They make up the aorta
They have relatively thin walls

They help control vasoconstriction
They are the smallest arteries
They transport blood to most of the major organs of the body
What structure would you least likely find a valve in?
Veins

Aorta
Which of the following statements is true?
Arteries have thinner walls than veins
Semilunar valves are found between the atria and ventricles
