Where is the interventricular septum located?
The ventricular septum (also called the interventricular septum) is the wall that separates the two large chambers (called ventricles) of the heart. One of its major purposes is to ensure that the relatively deoxygenated blood of the right ventricle stays separate from the relatively oxygenated blood of the left ventricle.
What happens to the septum when it has a hole in it?
Some times the foramen ovale does not seal. Then you have blood flow from left atrium to right atrium. So there is more blood flow through the lungs. This may lead to pulmonary hypertension, with it's sequels.
Why are the walls of the lower chambers of the heart thicker and more muscular than the walls of the upper chambers?
Some terminology first: The upper chambers = atria (singular atrium) The lower chambers = ventricles The atria are responsible for receiving blood: the right atrium receives deoxygenated blood from the body and the left atrium receives oxygenated blood from the lungs. The atria only pump this blood into the ventricles and therefore do not need particularly thick muscular walls. The ventricles on the other hand are responsible for pumping the blood received from the atria to the body. The right ventricle pumps the deoxygenated blood it receives from the right atrium out of the heart and into the lungs. On the other hand, the left ventricle is responsible for pumping the oxygenated blood received by the left atrium to the rest of the body. It is because of the this that the walls on the side of left ventricle are the thickest. The left ventricle requires "more muscle" than the right ventricle as the distance it has to pump the blood is far greater. So, SHORT ANSWER: The walls of the lower chambers/ventricles are thicker and more muscular than the walls of the upper chambers/atria because they have to pump blood out of the heart and to the body as opposed to the atria which only receive blood from the body and then pump into the ventricles.
Do all body systems dump some product into the blood?
Yes, all the body systems usually dump some product into the blood. That is the essence of pumping blood to the heart.
What type of cells protect the neurons in the central nervous system from some substances in the blood?
Could one conclude that Ependymal cells & Oligodenrocytes blood cells in the CNS protects neurons from some blood substances in blood.
Is there a certain percentage of oxygen in the deoxygenated blood when it heads back to the heart in the veins?
The oxygen is given by way of diffusion in the capillary system. Oxygen is not taken actively by the cells. So some oxygen is bound to be there in the deoxygenated blood. You have roughly half the oxygen, that comes back in deoxygenated blood.
What tubes connected to the heart?
what are some tubes connected to the heart
If blood entering the heart mixed with blood leaving the heart?
The heart has 4 chambers, the purpose of which is to send deoxygenated blood it receives from the body to the lungs, and to receive oxygenated blood from the lungs and to pump it all through the body. If through some problem the deoxygenated blood and oxygenated blood are mixed and sent out, then the % of oxygenated blood will be lower. Your whole body suffers when you don't get enough oxygen. If a heart has the kind of problem that causes this, the body could be in serious trouble.
What is physiological shunt?
Is a mixtures of oxygenated blood with some deoxygenated blood. It results in reduction of arterial PO2 by 2mmHg and reduction of arterial oxygen saturation by 0.5% compared to oxygenated blood coming from alveolar capillaries
Do blood vessels that enter and exit the heart carry oxygenated blood?
The blood vessels that enter the left side of the heart carry deoxygenated blood. The blood sent to the lungs via pulmonary arteries is also deoxygenated blood. The blood carried to the left side of the heart from lungs is oxygenated blood. The blood sent to the body via systemic arteries is oxygenated blood. So the right side of the heart deals with deoxygenated blood. Left side of the heart deals with oxygenated blood. The amount of blood flows is almost exactly same in both the sides of the heart. The only difference is you can measure the blood pressure from the greater circulation easily. So you tend to imagine that there is more blood in the greater circulation. The blood flow via pulmonary circulation can not be measured. So it is usually taken for granted and neglected. This blood flow is equally important.( Just like you take it for grated the gifts of the nature. Pure and fresh air, sunlight, rains and trees. Rather the ecosystem.)
What is the name of Blood that has no oxygen in it?
Scientifically speaking, No. If you had blood anywhere in your body with no oxygen, you would most likely be dead. There is, however a condition called deoxygenated blood, which occurs mostly in veins that are returning blood to the heart to be pumped to the lungs via the pulmonary arteries to become oxygenated. The difference between oxygenated blood and deoxygenated blood is only about 25%. This means that your blood is always carrying some oxygen, only sometimes at full capacity and sometimes at partial capacity. When it just leaves your lungs, at full capacity, it is carrying its full load at 100%. But when it is returning to the heart and lungs from using up some of its oxygen during metabolism in the body tissues, it is carrying a load of carbon dioxide, which drops its oxygen carrying capacity to 75%. This 75% carrying capacity is called deoxygenated blood. So, I hope your blood has some oxygen in it!
What Do Arteries Do In The Body?
arteries as a rule carry pure/oxygenated blood from left ventricle to different parts of body except pulmonary artery which carries impure , deoxygenated blood. Thus every role which is attributable to some extent to arteries. one of the important function of blood can be understood by role of hot water pipes used as a heating system, in the same way arteries distribute heat to whole of the body by distributing blood. arteries supply nutrients to all the body cells except few(e.g. retina) and hence make their survival possible.
Do the valves of veins keep blood flowing in one direction?
yes.it prevent the intermixing of oxygenated and deoxygenated blood
Why do some of the blood vessels in your wrist look blue?
deoxygenated blood looks slightly purple/blue as the fe^2+ prosthetic groups in the erythrocytes (red blood cells) are not bound to O2. when they are, they appear the colour red that is seen when blood is exposed to the air.
Why a person cannot survive with a hole in his heart?
Human heart has got four chambers. There are holes that inter connect them. But these holes have valves to control the flow of blood in between them. Some chambers contain only purified blood and some others contain impure blood collected from all over the body. If a hole appears on a wall separating them, they mix up and impure blood will be supplied to our body organs. they slowly get polluted and eventually can lead to death also! Another case happens when the hole on the outer wall of the heart or when the hole is between chambers containing same kind of blood. Here the adverse effect comes due to the pressure of the heart. When heart contracts its walls for supplying impure blood to kidney and pure blood to other body parts, the blood leak out through the hole and it do not reach where it is meant for.
What are some What are facts about blood?
Drinking human blood induces vomiting. Except for vampires. Blood is never blue! Deoxygenated blood is light red and oxygenated blood is dark red. Thousands of pints of blood donated to the Red Cross during Katrina were wasted. You can buy pig blood at your local super market or butcher.
Is water a mixture or impure substance?
yes water is mixture of many impure substances and bacteria.even pure water has some bacterias.
