it's a valve- not a muscle

What is it called when Blood coming into the right side of the heart from the body?
The circulation performed by the right side of the heart is the Pulmonary Circulation. When the heart receives oxygen poor blood - because the oxygen in the hemoglobin of the red blood cells has been offloaded to all the body's cells - it enters the first chamber, the right atrium, goes through a valve to the right ventricle, the first valve is closed, the ventricle contracts (the heart is a muscle after all) and ejects its load of blood through a second valve into the pulmonary trunk which splits into two pulmonary arteries that go to the right and left lung. In the lungs, the red blood cells get rid of carbon dioxide that they picked up as waste products from the body's cells, which we breath out, and then picks up a new load of oxygen that we breath in. This oxygen rich blood is returned to heart via the pulmonary veins to enter the Systemic Circulation on the left side of the heart to send the blood out to provide oxygen once again to body cells.
What is the movement of blood around heart tissue called?
The movement of blood to the heart tissue is called myocardial perfusion. In order for the myocardium (the heart muscle) to get oxygen and nutrients it has its own circulation providing a blood supply known as the coronary circulation. The coronary arteries (oxygenated blood vessels of the heart) supply nutrients and oxygen to the heart muscles between heart beats when the heart is relaxed (during diastole). Blood is routed from the surface of the heart muscle to deeper tissues of the myocardium. After delivering oxygen and nutrients to the cells of the heart, coronary veins pick up the blood and route it into the pulmonary (lungs) circulation where it can become re-oxygenated and return oxygenated blood back to the heart.
Why does walking prevent stagnation of blood in the legs?
The venous circulation of the legs requires muscle contractions to assist with blood return. Walking helps provide this muscle contraction.
Where is the thickest wall of the heart located?
The left ventricle, being responsible for pumping the blood through the systemic circulation, generates the highest pressures. For this reason, the left ventricle has the thickest muscular walls.
What is the difference between cor pulmonale and pulmonary embolism?
A pulmonary embolism is a tissue fragment (part of a blood clot, fat, amniotic fluid, part of a tumour or bullet fragment) that became loose in the blood stream and was carried by the blood stream to a different location. A pulmonary embolism is, in most cases, a thromboembolism (part of a blood clot), which is carried from the deep veins of the legs or the pevis. It travels up the blood stream, through the inferior vena cava, into the heart, and subsequently into the pulmonary artery. In the pulmonary artery, it arrests, forming a potentially life threating occlusion. Cor pulmonale is hypertrophy of the right ventricle due to chronic pulmonary hypertension. The pulmonay hypertension means that the right ventricle has to pump blood with greater force, causing its muscle to hypertrophy (enlarge in size). Therefore, to summarize, a pulmonary embolism is an obstruction of pulmonary blood flow while cor pulmonale is the morphological change of the right ventricle due to pulmonary hypertension.
What is the type of circulation that provides blood to the heart?
The coronary circulation provides a blood supply to the muscle of the heart. It is considered part of the systemic circulation.
Function of the cardiac muscle?
Cardiac muscle tissue is the tissue that makes up the bulk of your heart and when it contracts it will squeeze blood to your lungs through the pulmonary circuit, and to the rest your body through the systemic circuit.
The muscle that separates the abdominopelvic cavity from the pleural cavity is what?
The muscle that separates the abdomen pelvic cavity and the pleural cavity is the diaphragm.
What are the subsystems of the circulatory system and what does each subsystem do?
Pulmonary circulatory system pumps the oxygen-depleted blood away from the heart.Systemic circulation is the circulation of the blood to all parts of the body except the lungs.Coronary circulatory system provides a blood supply to the myocardium (the heart muscle).
What's the main muscle of the pulmonary system?
The main muscle of the pulmonary system is the diaphragm,which is important for breathing and respiration.It is responsible for 45% of the air that is inhaled.
What muscle separates the chest from the abdomen and forms the floor of the thorax?
The muscle that separates the chest from the abdomen and forms the floor of the thorax is called the diaphragm.
What are the three paths of blood circulation?
The three main paths are the pulmonary path which moves from the heart to the lungs and back, the somatic path where blood flows to the tissues and back and the flow of blood to the muscle of the heart and back.
What is the thin sheet of muscle called that separates the lungs from the intestines?
the diaphragm muscle
What is the muscle that separates the left side and right side of the heart?
The muscle that separates the right and left side of the heart is called the interventricular septum and is just a continuation of the cardiac (Heart) muscle of the heart's walls.
What has the author D H Glaister written?
D. H. Glaister has written: 'The effect of positive acceleration upon pulmonary artery pressure in man' -- subject(s): Acceleration (Physiology), Blood pressure, Pulmonary circulation 'Muscle blood flow determined by radioisotope clearance' -- subject(s): Blood flow, Measurement
Differentiate clearly between the location and appearance of pectinate muscle and trabeculae carnea?
In terms of location, the pectinate muscle can be found in the atrium, while the trabeculae carnea can be found in the ventricles. Also notice the trabeculae carnae should be thicker in the left ventricle as it is pumping blood into the systemic circuit (which has more surface area than the pulmonary circuit).
Is the muscle that separates the thoracic and abdominal cavitie?
The diaphragm
