Question

 A. Lymph = Plasma + RBC + WBC
 B. Blood = Plasma + RBC + WBC + Platelets
 C. Plasma = Blood - Lymphocytes
 D. Serum = Blood + Fibrinogen

Answer 1

Hint: Blood is a specialized fluid of the body. It has four major components: plasma, red blood cells, white blood cells, and platelets. Blood has many different types of functions, including the transportation of oxygen and nutrients to the lungs and tissues.

Complete answer:Blood is a specialized connective tissue consisting of a fluid matrix, plasma, and formed elements. Erythrocytes, leukocytes, and platelets are collectively called the formed elements and they constitute nearly 45 percent of the blood. -Blood, by definition, is a fluid that moves through the vessels of a circulatory system in our body. In humans, it includes plasma, blood cells RBC, WBC (which come in both red and white varieties), and cell fragments called platelets(thrombocytes). -Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in.
-Red blood cells(RBC) are responsible for carrying oxygen and carbon dioxide.
-Platelets are responsible for the blood clotting mechanism.
-White blood cells(WBC) are part of the immune system and function in the immune response. -Cells and platelets make up about 45%percent of human blood, while plasma makes up the other 55% percent.
So, the correct option is B

Note: Blood carries oxygen and nutrients to all of the cells in your body. Blood cells also fight infection and control bleeding and clotting. Most blood cells are made in your bone marrow. They are constantly being made and replaced. How long a blood cell lasts before being replaced is called its lifespan.
