What is Blood Pressure? | #aumsum


It’s AumSum Time. What is blood pressure? It’s a form of acupressure. No. In order to deliver oxygen and nutrients. To each and every cell of our body. Our heart pushes blood through tubes called
blood vessels. As the blood moves, it exerts force on the
vessels’ walls. The measurement of this force of blood on
the walls is called blood pressure. The ideal blood pressure reading is. About 120 over 80 millimeters of mercury or
slightly below it. But why does the reading have 2 numbers? It is because our heart is constantly contracting
and relaxing. During a phase called systole. Our heart contracts to push the blood through
arteries. Thus increasing the pressure. So, the bigger number indicates the systolic
blood pressure. Whereas during diastole, our heart relaxes,
decreasing the pressure. So, the smaller number indicates the diastolic
blood pressure. How does blood clot? With the help of glue. Not at all. Our blood consists of red blood cells, white
blood cells. Platelets, clotting factors, etc. suspended
in a liquid plasma. Hey. I too have a plasma, look. Oh. Please listen. Usually, when a blood vessel gets ruptured
and we bleed. Our blood begins to form a clot. First, the platelets start sticking to the
broken vessel and each other. Thus forming a loose plug. But this plug is not enough to stop bleeding. Hence, the clotting factors take part. In a complex chain of chemical reactions and
create fibrin strands. These strands criss-cross one another and
create a mesh. That tightly holds the loose plug together
and makes it strong. Red blood cells and white blood cells also
get trapped in the mesh. Thus creating a blood clot that completely
stops bleeding. Why is blood red in color? Because everyday it bathes using red paint. No. Our blood mainly consists of. A liquid called plasma, red blood cells, white
blood cells and platelets. However, the color of our blood is basically
because of red blood cells. Each of the red blood cells contains hemoglobin. Hemoglobin is an iron rich protein. When hemoglobin binds with oxygen. The interaction between them gives our blood
its red color. Moreover, like human beings, not all animals
have red color blood. This is because the blood of some animals. Such as octopuses, spiders, etc. has hemocyanin
instead of hemoglobin. Hemocyanin is a copper containing protein. When hemocyanin binds with oxygen, their interaction
gives the blood a blue color. The blood of some lizards has biliverdin instead
of hemoglobin. Which give their
blood a green color. Blood Rain. Relax. Blood rain has red colored water droplets. There are various reasons behind this. Around Sahara Desert. Brownish dust and sand carried by storms mix
with water droplets in clouds. Giving rain its brownish red color. In Kerala, red spores of algae called Trentepohlia
Annulata. Got carried by wind and mixed with water droplets,
causing blood rain. While, in Zamora, Haematococcus Pluvialis
algae got caught in rainclouds. Got stressed and produced a red pigment called
astaxanthin. Causing blood rain.
