Which components are found in blood?

The correct choice is identified by components that are fundamental to the composition of blood. Blood is primarily made up of various cellular and liquid elements that perform critical functions in the body.

Red corpuscles, also known as red blood cells, are responsible for transporting oxygen from the lungs to the rest of the body and returning carbon dioxide to be exhaled. White corpuscles, or white blood cells, play a key role in the immune system by defending the body against infections. Platelets are important for blood clotting and wound healing. Plasma, which makes up the majority of blood volume, is the liquid portion that transports cells, nutrients, waste products, hormones, and proteins throughout the body. Hemoglobin, found within red blood cells, is the protein that binds oxygen, enabling its transportation.

The other options contain components that are important for various bodily functions but are not directly found in blood in the same way. Glucose, carbohydrates, proteins, and fats are nutrients and metabolites that may circulate in the blood but are not structural components of blood itself. Lymph and serums relate to other fluids in the body, and while they have proteins and ions, they are distinct from blood. Cholesterol, uric acid, enzymes, and vitamins are
