Detailed explanation-1: -Your blood is made up of liquid and solids. The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets.

Detailed explanation-2: -Blood gets its bright red color when hemoglobin picks up oxygen in the lungs. As the blood travels through the body, the hemoglobin releases oxygen to the different body parts.

Detailed explanation-3: -Blood is a fluid connective tissue containing plasma, red blood cells (RBC), white blood cells (WBC), and platelets. It is the primary circulating fluid that aids in the movement of oxygen, carbon dioxide, nutrients, hormones, and wastes.

Detailed explanation-4: -blood, fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products. Technically, blood is a transport liquid pumped by the heart (or an equivalent structure) to all parts of the body, after which it is returned to the heart to repeat the process.

Detailed explanation-5: -The iron-containing complex protein known as haemoglobin is present in red blood cells (RBC). The haemoglobin contains red-colored compound heme, because of which the blood looks red in color. This heme compound helps in transporting oxygen in our blood.
