The internal environment differs more or less greatly from the external environment, depending on the species. The lungs are part of the respiratory system. Molecules are normally conveyed between cells and throughout the body of multicellular organisms in a circulatory fluid, called blood, through special channels, called blood vessels, by some form of pump, which, if restricted in position, is usually called a heart. The human circulatory system consists of blood, heart, blood vessels, and lymph. The major parts of the circulatory system are the Heart, Blood & Blood Vessels. When ventricular pressure rises above atrial pressure, the blood in the ventricle pushes the AV valve closed. The other two sulci extend obliquely down the heart from the coronary sulcus toward the apexone on the front of the heart called the anterior interventricular sulcus and one on the back called the posterior interventricular sulcus.

The right atrium is one of the four chambers of the heart. The contraction of the heart begins with autorhythmic depolarization of the sinoatrial node located in the superior portion of the posterior atrial wall.

Another part of the circulatory system is to remove waste from cells and organs so your body can dispose of it. The mitral valve, or bicuspid valve, separates the left atrium from the left ventricle. The main artery of the systemic circuit is the aorta which branches out into other arteries, carrying blood to different parts of the body. An instrument called the electrocardiograph amplifies these signals and produces a record on a moving paper chart. Skeletal muscle, the liver, and the kidney all have a large number of capillaries because their body systems need a lot of oxygen and nutrients.
