blood basics
blood is a specialized body fluid that has four main components
1 plasma
2 red - blood cells
3 white blood cells
4 platelets
blood has many different functions, including
1 regulating body temperature
2 transporting oxygen and nutrients to the lungs and tissues
3 forming blood clots to prevent excess blood loss
4 carrying cells and antibodies that fight infection
5 bringing waste products to the kidneys and liver, which filter and clean the blood
the blood that runs through the veins, arteries, and capillaries is known as whole blood. it is a mixture of about 55 percent plasma and 45 percent blood cells. about 7 to 8% of your total body weight is blood. an average - sized man has about 12 pints of blood in his body, and an average - sized woman has about nine pints
blood types
there are four major blood groups a, b, ab and o and are passed down through genetics. blood groups are based on red blood cell antigens, which are proteins on the cell surface that are recognized by a persons immune system
group a has one type of antigen (a), group b has a different type (b), group ab has both a and b antigens, and group o does not have either antigen. these blood groups are further divided by whether or not an antigen called the rh factor is present on the persons blood cells. if it is present, that persons blood is rh positive (+), if not, the blood is rh negative (-). combining rh factor with the four major blood types results in eight different main blood types
1 what are the 4 components of blood?
2 name 2 different functions of blood
3 what does it mean by whole blood?
4 how many pints of blood does an average person have?
5 what are the 4 major blood types?
6 list the antigens present on the red blood cells for the major blood types
7 how are the blood groups further broken down to create 8 different blood types?

Explanation:

1. The four components of blood are plasma, red - blood cells, white - blood cells, and platelets as stated in the text.
2. Two functions of blood are transporting oxygen and nutrients to the lungs and tissues, and carrying cells and antibodies that fight infection.
3. Whole blood is the mixture of about 55 percent plasma and 45 percent blood cells that runs through the veins, arteries, and capillaries.
4. An average - sized man has about 12 pints of blood and an average - sized woman has about 9 pints.
5. The four major blood types are A, B, AB, and O.
6. Group A has A antigen, Group B has B antigen, Group AB has both A and B antigens, and Group O has no A or B antigens.
7. Blood groups are further divided by the presence or absence of the Rh factor. If the Rh factor is present, the blood is Rh - positive (+), if not, it is Rh - negative (-).

Answer:

1. Plasma, red blood cells, white blood cells, platelets
2. Transporting oxygen and nutrients; carrying cells and antibodies that fight infection
3. A mixture of about 55 percent plasma and 45 percent blood cells that runs through veins, arteries, and capillaries
4. An average - sized man has about 12 pints, an average - sized woman has about 9 pints
5. A, B, AB, O
6. Group A: A antigen; Group B: B antigen; Group AB: A and B antigens; Group O: no A or B antigens
7. By the presence or absence of the Rh factor. If present, blood is Rh - positive (+), if not, blood is Rh - negative (-)
