At the peak of a contraction, the left ventricle has a higher pressure thanthe pressure of the veins.TrueFalse1234
2. Blood flows from the capillaries directly into _____.
3. In the systemic circuit, blood is carried away from the heart, delivered tomost organs and tissues, and returned back to the heart.TrueFalse4. As pressure builds in the right ventricle, the _____ valve closes, preventingthe backflow of blood into the right atrium.
5. Special junctions between cardiac cells that allow ions to pass freely fromone cell to another are called _____.

Copyright 2021 - Science Interactive | Exercise 1Cardiac contractile cells are present in the atria and ventricles of heart and are responsible for the heartcontraction which pump the blood to the various body parts. In cardiac contractile cells the sarcomeres arepresent which contain myofibril proteins along with the actin and myosin filaments. They also haveintercalated discs which allows the intercellular passage of ions and help in the transmission of the electricalimpulses rapidly. These all unique features are necessary for the heart contraction and are absent in theskeletal and smooth muscle cells.
