Yes, this is a good blood pressure.  normal range is between 100/60 and 120/80 approximately.  The top number is the pressure when the heart is squeezed during a beat and all the blood is in the vessels.  The bottom number is the pressure when the heart is relaxed during a beat and blood fills the heart, so less is in the vessels.

Normal range of Systolic blood preasure 100-139 mmHg\n\nNormal range of diastolic blood pressure 60-90 mmHg\n\nNormal Pulse Pressure (difference between both)= 30-50 mmHg\n\nanything close to the maximum is called high normal nad should keep checking regularly because he is high liability of becoming hypertensive. however, there's nothing called low normal.Hypotension is only feared when any of diastolic or systolic pressure is below the above stated number\n\nso you r just fine

The top number is the systolic rate,the bottom number is the diastolic rate.\n\nSystolic pressure (the higher,first #) measures the force that the blood exerts on the artery walls as the heart contracts to pump the blood.\n\nDiastolic pressure (the lower second #) is the measurement of force as the heart relaxes to allow blood to flow to the heart.

always in your arm. Blood travels first to your arm from your lungs. Blood is oxygenated in your lungs. Therefore there is more pressure in blood near your lungs. The first places after lungs have hte most pressure. Then slowly it decreases. The legs get teh least pressure. When blood goes across capellaries and hte O2 is used up and the pressure is very low. It is lowest in veins since all oxygen has been used up. It is also lowest far away from the heart because the heart increases pressure.

Blood plasma, red blood cells, white blood cells, platelets, and numerous nutrients that are being delivered to various parts of your body.  \n\nStructurally speaking, the circulatory system is a complex set of arteries drawing blood away from your lungs and to every part of your body (including the brain and heart muscle), veins drawing blood toward your lungs, the heart that pumps to keep blood moving, and capillaries that drop of oxygen to cell tissue in exchange for carbon dioxide.

Our heart is a pump, a very efficient one. The whole body consists of various circuits. And there are valves which control the flow of blood. Since the heart pumps blood, that is, it sends the blood at a certain pressure, the flood flows to various body parts and back, whatever the body position is, horizontal or vertical. This applies to the lowest part of our bodies (foot) too, when we stand up.

The Circulation of Blood\n\nThe human circulatory system is really a two-part system whose purpose is to bring oxygen-bearing blood to all the tissues of the body. When the heart contracts it pushes the blood out into two major loops or cycles. In the systemic loop, the blood circulates into the body’s systems, bringing oxygen to all its organs, structures and tissues and collecting carbon dioxide waste. In the pulmonary loop, the blood circulates to and from the lungs, to release the carbon dioxide and pick up new oxygen. The systemic cycle is controlled by the left side of the heart, the pulmonary cycle by the right side of the heart. Let’s look at what happens during each cycle:\n\nThe systemic loop begins when the oxygen-rich blood coming from the lungs enters the upper left chamber of the heart, the left atrium. As the chamber fills, it presses open the mitral valve and the blood flows down into the left ventricle. When the ventricles contract during a heartbeat, the blood on the left side is forced into the aorta. This largest artery of the body is an inch wide. The blood leaving the aorta brings oxygen to all the body’s cells through the network of ever smaller arteries and capillaries. The used blood from the body returns to the heart through the network of veins. All of the blood from the body is eventually collected into the two largest veins: the superior vena cava, which receives blood from the upper body, and the inferior vena cava, which receives blood from the lower body region. Both venae cavae empty the blood into the right atrium of the heart.\n\nFrom here the blood begins its journey through the pulmonary cycle. From the right atrium the blood descends into the right ventricle through the tricuspid valve. When the ventricle contracts, the blood is pushed into the pulmonary artery that branches into two main parts: one going to the left lung, one to the right lung. The fresh, oxygen-rich blood returns to the left atrium of the heart through the pulmonary veins.\n\nAlthough the circulatory system is made up of two cycles, both happen at the same time. The contraction of the heart muscle starts in the two atria, which push the blood into the ventricles. Then the walls of the ventricles squeeze together and force the blood out into the arteries: the aorta to the body and the pulmonary artery to the lungs. Afterwards, the heart muscle relaxes, allowing blood to flow in from the veins and fill the atria again. In healthy people the normal (resting) heart rate is about 72 beats per minute, but it can go much higher during strenuous exercise. Scientists have estimated that it takes about 30 seconds for a given portion of the blood to complete the entire cycle: from lungs to heart to body, back to the heart and out to the lungs.\n\n^_^

The heart is a fist-sized, muscular organ that pumps blood through the body. Oxygen-poor blood enters the right atrium of the heart (via veins called the inferior vena cava and the superior vena cava). The blood is then pumped into the right ventricle and then through the pulmonary artery to the lungs, where the blood is enriched with oxygen (and loses carbon dioxide). The oxygen-rich (oxygenated) blood is then carried back to the left atrium of the heart via the pulmonary vein. The blood is then pumped to the left ventricle, then the blood is pumped through the aorta and to the rest of the body. This cycle is then repeated. Every day, the heart pumps about 2,000 gallons (7,600 liters) of blood, beating about 100,000 times. enchantedlearning.com

backflow may occur where some of the blood goes backwards, leading to a slow circulation

Veins carry deoxygenated blood from the organs and tissues back to the heart.\nDeoxygenated blood from the body enters the right atrium through two great veins, the superior vena cava which drains the upper part of the body and the inferior vena cava that drains the lower part which drains the portal cyrculation too full with nutrients to nourish the body.

The body's circulation has two parts, with the heart acting as a double pump. Blood from the right side pump is dark red (bluish) and low in oxygen. It travels along pulmonary arteries to the lungs where it receives fresh supplies of oxygen and becomes bright red. It flows along pulmonary veins back to the heart's left side pump.\n\n \n\n \n\n\nBlood leaves the left side of the heart and travels through arteries which gradually divide into capillaries. In the capillaries, food and oxygen are released to the body cells, and carbon dioxide and other waste products are returned to the bloodstream.The blood then travels in veins back to the right side of the heart, and the whole process begins again.
