Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart. Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances. The capillaries also connect the branches of arteries and to the branches of veins. The walls of most blood vessels have three distinct layers: the tunica externa, the tunica media, and the tunica intima. These layers surround the lumen, the hollow interior through which blood flows.
The left ventricle of the heart pumps oxygenated blood into the aorta. From there, blood passes through major arteries, which branch into muscular arteries and then microscopic arterioles. The arterioles branch into the capillary networks that supply tissues with oxygen and nutrients. The walls of arteries are thicker than the walls of veins, with more smooth muscle and elastic tissue. This structure allows arteries to dilate as blood pumps through them.
After the capillaries release oxygen and other substances from blood into body tissues, they feed the blood back toward the veins. First the blood enters microscopic vein branches called venules. The venules conduct the blood into the veins, which transport it back to the heart through the venae cavae. Vein walls are thinner and less elastic than artery walls. The pressure pushing blood through them is not as great. In fact, there are valves within the lumen of veins to prevent the backflow of blood.
Capillaries are tiny vessels that branch out from arterioles to form networks around body cells. In the lungs, capillaries absorb oxygen from inhaled air into the bloodstream and release carbon dioxide for exhalation. Elsewhere in the body, oxygen and other nutrients diffuse from blood in the capillaries to the tissues they supply. The capillaries absorb carbon dioxide and other waste products from the tissues and then flow the deoxygenated blood into the veins.
The blood moving through the circulatory system puts pressure on the walls of the blood vessels. Blood pressure results from the blood flow force generated by the pumping heart and the resistance of the blood vessel walls. When the heart contracts, it pumps blood out through the arteries. The blood pushes against the vessel walls and flows faster under this high pressure. When the ventricles relax, the vessel walls push back against the decreased force. Blood flow slows down under this low pressure.
The heart is the hardest working muscle in the human body. Located almost in the center of the chest, a healthy adult heart is the size of a clenched adult fist. By age 70, the human heart will beat more than 2.5 billion times. The heart is always working. It pumps about 2,000 gallons of blood daily.
4 chambers. The 2 upper chambers are the atria. They receive and collect blood. The 2 lower chambers are the ventricles. They pump blood to other parts of your body. Here is the process:
You may still donate blood, platelets or plasma after receiving a COVID-19 vaccine. Knowing the name of the manufacturer of the vaccine is important in determining your blood donation eligibility. To learn more about the COVID-19 vaccine and blood donation, click here »

Your blood oxygen level represents the percentage of oxygen your red blood cells carry from your lungs to the rest of your body. Knowing how well your blood performs this vital task can help you understand your overall wellness.
The majority of people have a blood oxygen level of 95 - 100%. However, some people live a normal life with blood oxygen levels below 95%. Slightly lower values while sleeping are expected, and some users might experience values below 95%.
Even under ideal conditions, your Apple Watch may not be able to get a reliable blood oxygen measurement every time. For a small percentage of users, various factors may make it impossible to get any blood oxygen measurement.
About background measurements The Blood Oxygen app on your Apple Watch will occasionally measure your blood oxygen levels if background measurements are on. This will usually happen when you are not moving. Depending on how active you are, the number of readings collected each day and the time between these readings will vary. Blood oxygen measurements use a bright red light that shines against your wrist, so it may be more visible in dark environments. If you find the light distracting, you can turn off background measurements.
That said, they may transfuse white blood cells called granulocytes to help a person recover from an infection that has not responded to antibiotics. Healthcare professionals can collect granulocytes using a process called apheresis.
Blood transfusions are necessary when the body lacks enough blood to function properly. For example, a person may need a blood transfusion if they have sustained a severe injury or if they have lost blood during surgery.
Health conditions that affect the blood can be life threatening, but effective treatment is often available. In the United States, blood diseases accounted for 10,066 deaths in 2008, mostly different types of anemia.
Red blood cells have a slightly indented, flattened disk shape. They transport oxygen to and from the lungs. Hemoglobin is a protein that contains iron and carries oxygen to its destination. The life span of a red blood cell is 4 months, and the body replaces them regularly. The human body produces around 2 million blood cells every second.
Bone marrow produces red blood cells, white blood cells, and platelets, and from there they enter the bloodstream. Plasma is mostly water that is absorbed from ingested food and fluid by the intestines. The heart pumps them around the body as blood by way of the blood vessels.
The platelets in blood enable the clotting, or coagulation, of blood. When bleeding occurs, the platelets group together to create a clot. The clot forms a scab, which stops the bleeding and helps protect the wound from infection.
Blood groups are important during pregnancy. If a pregnant person has RhD-negative blood, for example, but the fetus inherits RhD-positive blood, treatment will be necessary to prevent a condition known as hemolytic disease of the newborn.
Blood is essential for maintaining the health and life of the human body. It has many functions, including delivering nutrients and oxygen. The four main components of blood are red blood cells, white blood cells, plasma, and platelets.
The blood pressure readings have two numbers (e. g. 118/78 mmHg, which is Systolic/Diastolic or SYS/DIA). The highest pressure in the cycle is called the Systolic Blood Pressure. The lowest is the Diastolic Blood Pressure. Both are necessary to enable healthcare professional to evaluate the status of your blood pressure.
A single measurement does not provide an accurate indication of your true blood pressure. Please use this Blood Pressure Diary* or Blood Pressure Pass* to keep records of several readings over a certain period of time.

It offers basic information about the medication, including reasons why a clinician might prescribe it. It also includes tips on diet, medicines and foods to avoid, important precautions for some daily activities, and when to seek help.
Your doctor has prescribed a medicine called a blood thinner to prevent blood clots. Blood clots can put you at risk for heart attack, stroke, and other serious medical problems. A blood thinner is a kind of drug called an anticoagulant (an-te-ko-AG-u-lent). "Anti" means against and "coagulant" means to thicken into a gel or solid.
You and your doctor will work together as a team to make sure that taking your blood thinner does not stop you from living well and safely. The information in this booklet will help you understand why you are taking a blood thinner and how to keep yourself healthy. Please take time to read all of the information in this booklet.
There are different types of blood thinners. The most common blood thinner that doctors prescribe is warfarin (Coumadin®, COU-mad-din). Your doctor may also discuss using one of the newer blood thinners depending on your individual situation. 2b1af7f3a8
