because the heart have valves
It is a very quick way to increase blood volume.
The nucleus of a cell keeps the cell going because its the mainframe of a cell so it controls what happens within a cell,what the cell does and how the cell will be used.
Blood flows in one direction due to the presence of one-way valves in veins that prevent backflow. The pumping action of the heart pushes oxygenated blood through arteries to the tissues, while deoxygenated blood is returned to the heart through veins. This one-way flow ensures efficient circulation throughout the body.
Blood is the tissue composed of plasma and various types of cells. Plasma is the liquid component of blood, while cells such as red blood cells, white blood cells, and platelets make up the cellular components. Together, these components work together to carry out vital functions in the body, such as transporting oxygen, fighting infections, and preventing excessive bleeding.
Red blood cells, known also as RBCs, have several important roles to play in our bodies. The primary function of red blood cells is to carry oxygen from the lungs to the tissues around your body. As a secondary function, they are also a key player in getting waste carbon dioxide from your tissues to your lungs, where it can be breathed out. When red blood cells stop functioning properly, you can rest assured that many things are going to go wrong in your body
Veins.
Pakistan is going backward due to corrupt leadership .
NO, no, no, no, no! That is a silly question. Arteries are red, Veins are blue, Ask another question like this and ur going down. Veins are blue because they carry de-oxygenated blood and wastes, not arteries
With the exception of the vessels going to and from the lungs, veins carry blood to the heart from the body.
no, because ward is a word, but it has nothing to do with going backwards.
pakistan is going backward due to poor management in every field,unmatchable policies and corruption
The vessels that carry blood to the heart are called veins and the vessels that carry blood away from the heart are called arteries.Arteries Always carry blood Away from the heart. Most are oxygenated except the pulmonary arteries which are low in oxygen and are going to the lungs to pick up oxygen.
bronchus and why is this in public health ans SAFETY
Veins almost always carry deoxygenated blood from the periferal areas of the body to the heart. The veins going from our lungs to the heart, the pulmonary veins, however, carry oxygenated blood. Therefore the answer is: The pulmonary veins.
For the most part, arteries carry oxygenated blood and veins carry de-oxygenated blood. This is opposite in the pulmonary veins and arteries because they are going to and from the lungs to get oxygen.
When one of the heart ventricles (the lower chambers) contracts, it pushes blood out of the heart. A valve prevents this blood from going backward into the atrium, which has completed its contraction and is now relaxed and being filled with blood from the veins.
yes. the arteries going from the heart to the lungs contain deoxygenized blood
