When a person's hand is cold and the other is hot, this could mean many things. It might mean there is poor circulation through the cold one, or that they were laying on the one that is warm.
It moves around within the Paramecium cell, distributing food, nutrients, and other needed materials to different parts of the cell.
During atrial systole 70 percent of ventricular filling occurs?
No. Most (~70%) of ventricular filling occurs passively, without atrial contraction.
What may damaged high blood pressure?
The brain, the eyes, hearing, internal organs, skin, nearly everything in the body can be negatively affected by long term bouts of high blood pressure.
Is implantation bleeding bright red?
no, it's a brownish pink, and does not look like normal period blood.
What can your circulatory system best compared to?
A good and simple analogy for the circulatory system is a system of roads and towns.
The main blood vessels are the motorways; the capillaries can be compared to rural country lanes. The blood cells can be compared to vehicles: red blood cells to trucks and lorries (carrying oxygen and carbon dioxide), white blood cells are best compared to police cars (protecting us from harm!). Towns, cities, villages and buildings which are passed by the vehicles represent the body cells and organs that our red blood cells unload their oxygen or CO2.
This isn't a foolproof analogy, but it is a decent attempt at relating in layman's terms the function of the circulatory system.
the routine measurements that could be taken to monitor the functioning of asthma is peak flow measurement.
Blood is forced into the blank each time the blank contract?
Blood is forced into the ventricles each time the atria contact.
*do you go to Smith Language Academy because we had the same question on our extra-credit. :-)
Why does your heart beat faster when you exercise?
When muscles are used for exercise, they must be replenished with oxygen, nutrients, etc. They also produce waste products that need to be taken away from the cells. Blood is the transport system for all of these things, so the harder your muscles are worked, the quicker they burn through nutrients and produce waste, meaning that the blood must flow faster to provide all of this; the only way for blood to flow faster is for your heart to beat faster.
Resting muscle gets about 750 ml of blood out of your 5 liters of cardiac out put. During exercise the cardiac output may go up to 25 liters per minute. Out of these 25 liters of cardiac out put, your muscles get about 20 liters of blood to meet the metabolic requirements of oxygen and food material. The stroke volume of heart increases but then heart rate also increases from 72 per minute to up to 180 beats per minute.
Yes, but if you increase the speed of your breathing too much you can hyperventilate and / or pass out.
What is the respiration system?
if you mean the "respratory system" that is the cycle of breathing but if you are inquireing the "resperation system" im not really sure...

name one quantity that must be known in order to determine the amount of heat associated with the body
What is a description of the splanchnic circulation?
The splanchnic circulation is a particular bloodflow. It moves through the regions of the stomach, small intestine, colon, pancreas, and spleen.
Whats in order of those parts that determine the direction of blood flow through the heart?
Vena cava>right atrium>right ventricle>pulmonary artery>pulmonary vein>left atrium>left ventricle>aorta

Which is essential for formation of RBC?
if we consider the formation of RBCs Erythropoietin, produced by the kidneys, signals RBC formation in the red bone marrow is required.
but if we consider the activation of rbc so haemoglobin is essential, in which haemoglobin consiats of single molecule so we can also say for the activation of rbc that:-
IRON------>HAEMOGLOBIN------>RBC
and RBC are produced as
BY KIDNEY------->ERTHROPROTEIN------>RBC
