Answer: The heart has four chambers: the right and left atrium are superior to the right and left ventricles. The atrium are smaller and have thinner walls than the ventricles. Internally, the atria are separated by the interventricular septum. Thus, the heart has a right and left side. ...
The left semilunar valve, between the left ventricle and aorta, is also called the aortic valve. Muscle tissue known as myocardium or cardiac muscle wraps around a scaffolding of tough connective tissue to form the walls of the heart’s chambers. The atria, the receiving chambers of the heart...
one of the pair of smaller cavities of the heart, with thick muscular walls, from which the blood passes to the ventricles. right atrium - (right side of the heart) receives blood from the superior and inferior vena cava and delivers it to the right ventricle. left atrium receives blood ...
• The left ventricle has even thicker muscular walls than the right ventricle. The left ventricle needs a more powerful contraction to propel blood to the systemic circulation (all of the body apart from the lungs). The right ventricle propels blood to the nearby lungs. The contraction does...
The primary function of the heart is to serve as a muscular pump propelling blood into and throughvesselsto and from all parts of the body. The arteries, which receive this blood at high pressure and velocity and conduct it throughout the body, have thick walls that are composed of elastic...

Many bacteria and archaea possess a two-dimensional protein array, or S-layer, that covers the cell surface and plays crucial roles in cell physiology. Here, we report the crystal structure of SlpA, the main S-layer protein of the bacterial pathogen Clos

The cell walls of lymph vessels are more permeable than those of the capillary walls of blood vessels. Thus, proteins that may have been delivered to the tissues by the bloodstream but that are too big to reenter the capillaries, along with waste products and large proteins synthesized in the...
Epithelial tissue is found in many locations throughout the body. A few examples include the outside surface of skin, the linings of all digestive organs, the lining of the heart, the inner and outer membranes of the respiratory system, vessel walls, and the internal body cavities. What are...
