Blood flows past the aortic semilunar valve when the contracts. A. left atrium B. right atrium C. left ventricle D. right ventricle 5. Which is true? A. The left atrium contracts before the right atrium.
Describe the four valves of the heart, including their name, location, and function. The four valves of the heart are the tricuspid valve, the pulmonic valve, the mitral valve, and the aortic valve. The tricuspid valve: It is located between the right atria and the right ventricle. It is comprised of three “flap-like cusps” which when in its closed position, prevents the deoxygenated blood entering the heart from the body, from backing up in the right atrium from the right ventricle (regurgitation). http://www.healthline.com/human-body-maps/tricuspid-valve The Pulmonic Valve: This valve is found between the right ventricle and the lungs.
1. Cardiovascular System is a complex network of the heart, blood vessels and blood. Its job is to deliver nutrients to the human body and remove excretory products from the body parts, it’s also protects the human body against infections, distribution of heat. At the centre of the cardiovascular system is the heart, a four chambered pump that dispenses blood to the arteries. The arteries carry nutrients and oxygenated blood to the body’s tissues.
The heart consists of 2 ventricles, and also 2 atria. There is a right atrium and also ventricle, this is where the blood comes from the veins. The deoxygenated blood then goes into the right atrium of the heart. Blood is released from the atrium and goes into the right ventricle, this happens when the heart relaxes, this is where the right ventricle pushes blood in through pulmonary valve and eventually into pulmonary artery, this is the place where the blood its given to the lungs because to get back oxygen. Lastly the blood is then given back to hearts left side.

The cardiac cycle is vital in all organisms with a heart, to pump blood round the body. There are phases of the cardiac cycle; systole (contraction) and diastole (relaxation). The heart consists of 4 chambers, 2 being the atria at the top of the heart and the other 2 being the ventricles at the bottom of the heart. Systole occurs separately in the atria and ventricles and diastole occurs simultaneously in all 4 chambers. The cardiac cycle is controlled by electrical waves that spread throughout the heart.
This paper aims to describe the pathophysiology of atrial fibrillation and the rationale behind the information included in the patient education tool. Atrial Fibrillation: A Patient Education Guide The heart is a muscle that contains four chambers; the right atrium, left atrium, right ventricle, and left ventricle. Each of these chambers has a purpose. The right ventricle pumps blood to the lungs and the left ventricle pumps blood to the rest of the body. The right atrium receives deoxygenated blood via the superior and inferior vena cava.
Cardiopulmonary resecitation is an emergency procedure for life support consisting of artificial respirations and external cardio 18. Ishemic Heart Disease is a group of cardiac disabilities resulting from an insufficient supply of oxygenated blood to the heart. 19. Tissue Plasmogin Activator is administered after heart attacks and stroke to reduce blood clots. 20.
When the ductus arteriosus refuses to close, the oxygenated blood in the aortic arch passes into the left branch of the pulmonary artery and produces pulmonary hypertension. B. Draw a diagram outlining blood flow related to this clinical complication. C. Be prepared to discuss complications and treatments of this clinical conditional. In infants, complications that may occur are risks of developing heart failure, pulmonary artery hypertension, or infective endocarditis, which is an infection of the inner lining of the heart.
As we continue to make our way to the heart, we merge with the right external iliac vein. This is also another name for the femoral vein, and is also considered a deep vein in the lower leg. Its main responsibility is taking deoxygenated blood from the legs back to the heart. It is located right behind the inguinal ligament in the lower abdomen. The inguinal ligament support the area between the abdomen and the thigh (Inguinal Ligament, n.d.).
