Which of the Following Statements Is True of Antigen-Antibody Interactions?
Microorganisms carry foreign antigens on their surfaces which stimulate the production of white cell antibodies that attack the antigens as a way of getting rid of the invading parasites and subsequently develop an immunity to future attacks.
In A Blood-Pressure Reading, The Numbers Represent Units of Mercury.
Each of the numbers in a blood-pressure reading of, say, 120 over 80, represents millimeters of mercury in a device that looks like a thermometer. This unit is represented as mm Hg. In an adult, a normal reading would be below 120/80 mm Hg and above 90/60 mm Hg.
According to Guidelines laid by American Red Cross How Often Can a Donor Give Blood?
The American Red Cross recommends that healthy donors may donate whole red blood cells every 56 days (eight weeks/2 months), or Power Red every 112 days (16 weeks). It takes the body 8 weeks to replenish red and white blood cells.

Transfusions of one unit of red blood cells usually take two to four hours. Usually, a platelet transfusion takes between 30 and 60 minutes. You will be closely monitored by your nurse during the entire transfusion.
Which Blood Type Is the Universal Donor?
Emergency room personnel tend to reach for Type O negative blood when there is no time to determine the blood type of patients in the most serious situations.

This is why it is sometimes called the universal blood donor type.
When Blood Clumps or Forms Visible Islands In The Still Liquid Plasma, It Is Called:
Agglutination occurs when antibodies attach to antigens on alien red cells, resulting in the red cells sticking together. This recognition-rejection process occurs within the body and results in the bursting of alien red cells instead of agglutination. During clotting, the blood at a wound no longer remains liquid. Fibrinogen and other platelet clotting agents cause clotting.
The Thickest Blood Vessel in The Body Is
An artery is an oxygen-carrying vessel with a thick, muscular wall that always carries oxygenated blood away from the heart. High pressure would cause arteries to burst if they had thin walls. The thick walls of arteries explain why they have such a large diameter. A high pressure is created in the heart when it pumps blood. They must be able to withstand the tremendous pressure of a beating heart.
Which Of the Following Are Likely to Increase in Quantities When the Body Is Under Attack From Bacteria?
Leukocytes, or white blood cells, show up in increasing numbers at the site of infection in response to such an attack. The bacteria that invade the cells are attacked by them, and when they succeed, they are ultimately eliminated.
White Blood Cells Outnumber Red Blood Cells in The Human Body.
Technically known as leukocytes, white cells are outnumbered by red cells. Regardless of the volume of blood the ratio of WBC to RBC will remain the same, so the answer will always be 1:1000. ie. for every WBC, there will be 1000 RBC.

Other Name for Platelets is
Blood platelets, or thrombocytes, are small, colorless fragments that form clots and halt or prevent bleeding. Bone marrow, the sponge-like tissue within our bones, produces platelets. Stem cells in the bone marrow produce red blood cells, white blood cells, and platelets.
If You Are Taking Prescription Medication and You Go to Donate Blood, You Will Not Be Allowed to Donate.
This is false. You will almost never be disqualified from being a blood donor if you are taking medications. Instead, eligibility will be based on the reason that the medication was prescribed. Donating blood is usually permissible if your health is good and the condition is under control.
What is hematocrit?
A hematocrit is a standard blood test that is performed to measure the red blood cells in an individual's blood. Red blood cells (erythrocytes) are significant because they transport oxygen throughout your body. A high or low red blood cell tally can symbolize a medical condition or disease.
For How Long Does Blood from A Transfusion Stay in Your Body?
Blood transfusions usually take between 2-4 hours, depending on the reason for the procedure. Transfusions may provide benefits for up to 2 weeks, depending on circumstances.

The Most Well-Known and Medically Important Blood Types Are In The ABO Group. Which Of The Statement Is Correct Regarding ABO Group?
ABO blood groups can be determined for all humans and most primates. A, B, AB, and O are four principal types of blood groups. ABO types are mainly determined by two antigens and two antibodies. In most cases, an individual's type is determined by a specific combination of these four components.
Why Are Blood Transfusions Given?

How Much Blood Usually Is Donated at A Time?
One pint is the standard donation. During a regular donation, you will give around 470ml of whole blood. This is about 8% of the average adult's blood volume. The body replaces this volume within 24 to 48 hours, and replenishes red blood cells in 10 to 12 weeks. Once the blood is properly sealed in the bag, it is preservatived and treated with anti-clotting agents.
What Is the Minimum You Should Weigh to Donate Blood?
Donors are required to provide a comprehensive health history. An in-depth blood test that tests the donor's haemoglobin is then conducted to ensure that they can give blood without causing harm to themselves. A height and weight assessment may be necessary if you are under the age of 18.

Viscosity is characteristic of blood. To flow smoothly, there must be a continuous drop in pressure throughout the circulatory system. The aorta has the highest pressure, while the vena cava has the lowest.
