   Your heart pumps blood through three types of blood vessels: Arteries carry oxygen-rich blood from your heart to your body’s tissues. The exception is your pulmonary arteries, which go to your lungs. Veins carry oxygen-poor blood back to your heart. Capillaries are small blood vessels where your body exchanges oxygen-rich and oxygen-poor blood.

   The base of the heart is located along the body's midline with the apex pointing toward the left side. Because the heart points to the left, about 2/3 of the heart's mass is found on the left side of the body and the other 1/3 is on the right. Anatomy of the Heart Pericardium. The heart sits within a fluid-filled cavity called the pericardial ...

   Aug 8, 2023 · Cardiac muscle (or myocardium) makes up the thick middle layer of the heart. It is one of three types of muscle in the body, along with skeletal and smooth muscle. The myocardium is surrounded by a thin outer layer called the epicardium (AKA visceral pericardium) and an inner endocardium. Coronary arteries supply to the cardiac muscle, and cardiac veins drain this blood. Cardiomyocytes are the ...

   Where is cardiac muscle located?

   • Cardiac muscle is found in the walls of the heart. It helps the heart perform its function of pumping blood throughout the body. Cardiac muscle tissue is located in the middle of three layers of the heart, called the myocardium. Problems in the myocardium can cause heart failure and arrhythmias or contribute to sudden cardiac death.

   What is heart muscle tissue made up of?

   • At a cellular level, heart muscle tissue is made up of bundles or fibers of interconnected muscle cells, called cardiomyocytes. These cells are packed with units called sarcomeres that are made of proteins called actin and myosin. When stimulated, these two proteins slide against each other to result in contraction of the heart.
