The four valves in the heart are: * the two semi-lunar valves - one at the stem of the aorta, the other is found at the trunk of the pulmonary artery. * The tricuspid valve is on the right-hand side of the heart. * The bicuspid valve is on the left side of the heart.

∙ 9y agoThe atrioventricular valves are the "doors" that control blood flow between the atria and ventricles. The semilunar valves control blood flow out of the ventricles.

What is the function of the pericardium?
it prevents the heart from over expanding when the blood volume increasepericardium is a bag suuronding the heart which acts as a shock absorber.pericardium is a bag surronding the heart which acts as a shock absorber.The pericardium is the outer layer of the heart or a sack in which the heart is stored. It basically protects the heart and it's vessels.The purpose of it is to protect and lubricate the heart.the peircardium is the outermost coverin of your heart.. protects against friction rubs and protects againsts shocks(traumatic) as it contains 40-50 ml of pericardial fluid.. acts as a shock absorber
Do the lungs pump blood around the body?
The heart acts as a powerful pump to push the blood through the veins, arteries & capillaries to carry oxygen & sugar to fuel the muscles & organs that keep us alive; then carries the depleted blood to the lungs to pick up oxygen & the intestines to replenish the sugar
What happens during a heart attack and what is the effect of a heart attack on heart cells?
In a heart attack, the arteries are clogged up, and the heart cannot get blood circulation. It starts when a nick is created in the arteries. Floating LDL (bad cholesterol) binds up onto the nick, and white blood cells detect the bump, and responds by "eating" the LDL. However, the white blood cells get stuck ther that makes it grow even larger. Soon, the plaque ruptures, and it floats down the bloodstream. It settles in a different location, where it is blocking the bloodstream. If it settles in a critical location, then a heart attack ensues. A heart attack causes the heart to not be able to circulate blood. Without blood, people die. The best thing to do is to get more HDL (good cholesterol). It acts as a remover of excess LDL. You also can lower high blood pressure, if you have it.
How the heart acts as a double pump?
The heart has two sides which are independent of each other. When it pumps, it pumps both on the left and right sides. The left carries blood throughout all the body tissues, and the right side pushes blood into the lungs for oxygenation.
How does the heart help the lungs do its job in the human body?
The heart is the bodies blood pump. Blood with a low oxygen level enters the heart at the right atria where it is pumped to the right ventricle and then out of the heart through the pulmonary artery ( the only artery in the body that contains low oxygenated blood) and to the lungs. While in the lungs, the blood enters the alveoli where it off loads carbon dioxide molecules and up loads oxygen molecules. The now oxygenated blood returns to the heart into the left atria, is pumped to the left ventricle and then out to the body through the Aorta where it supplies the oxygen to the bodies cells and collects carbon dioxide and other wastes. The cycle begins again.
What acts like a pump that circulatory the blood?

Which organ acts as the control center of the body?

Aspirin acts as a blood thinner. Thus making the blood less likely to form clots. Clots are what can cause heart attacks and stroke.
How doees the heart and blood vessels maintain the circulation of blood in mammal?
The heart acts as a pump which circulates oxygenated blood through the arteries around the body at high pressure. Once gaseous exchange takes place between the cells and capillaries the deoxygenated blood flows back to the heart through the veins where it is pumped to the lungs via the pulmonary arteries. When the blood becomes oxygenated by external respiration it flows back to the heart via the pulmonary veins and the cycle starts again. Therefore the heart acts a pump and the blood vessels are a channel to circulate the blood around the body.
What does the parietal pericardium layer help to do?
acts to protect the heart, anchoring it to the surrounding walls, and preventing it from overfilling with blood
Why are the chest compression important in CPR?
It temporarily acts as the muscles to keep the heart beating and blood circulating through the body.

What keep blood flowing in a forward direction?
Your heart is responsible for keeping your blood flowing. It acts like a pump. The right side receives blood from the body where it is pumped to the lungs and the left side pumps the oxygenated blood out to your entire body. The valves of your heart keep it flowing in one direction.
