(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3​

Answer 1

Answer:

answer is no b is 2 and 3 only

Answer 2

Option A - 1 and 2 Only

■ Explanation :-

• Plasma is the largest part of our blood. It, makes up more than half (about 55%) of its overall content. When separated from the rest of the blood, plasma is a light yellow liquid. Plasma carries water, salts and enzymes. Hence, statement 1 is correct.

• The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma. The plasma then helps remove this waste from the body. Blood plasma also carries all parts of the blood through your circulatory system

• Along with water, salt, and enzymes, plasma also contains important components. These include antibodies, clotting factors, and the proteins albumin and fibrinogen. When you donate blood, healthcare providers can separate these vital parts from your plasma. These parts can then be concentrated into various products. These products are then used as treatments that can help save the lives of people suffering from burns, shock, trauma, and other medical emergencies.

• The proteins and antibodies in plasma are also used in therapies for rare chronic conditions. These include autoimmune disorders and hemophilia. People with these conditions can live long and productive lives because of the treatments. In fact, some health organizations call plasma "the gift of life." Hence, statement 2 is correct.

• During the actual blood donation process, your blood is drawn through a needle placed in a vein in one arm. A special machine separates the plasma and often the platelets from your blood sample. This process is called plasmapheresis. The remaining red blood cells and other blood components are then returned to your body, along with a little saline (salt) solution.

• People with AB type blood (positive or negative) are universal plasma donors. Antigens present in AB+ also play a vital role in plasma donations. While AB+ blood has both A and B antigens on the red blood cells, neither of the antigens are present in the plasma. This makes AB+ the universal plasma donor, meaning that AB+ plasma can be transfused into patients who have any other ABO blood type. Hence, statement 3 is not correct.
