Blood is a liquid connective tissue that contains cellular elements (blood cells) and fluid matrix (plasma). These cells are very important in the immune systems and are responsible for humoral and cell-mediated immunity. Blood is a fluid connective tissue which comprises plasma, various types of blood cells and platelets.

RBC carries oxygen from the lungs to all the cells of the body. In adults, this amounts to 4.5-6 quarts of blood; Carries out the critical functions of transporting oxygen and nutrients to our cells; Gets rid of carbon dioxide, ammonia, and other waste products; Plays a vital role in our immune system Their main function is to transport oxygen from and to various tissues and organs. When a sample of blood is spun in a centrifuge, the cells and cell fragments are separated from the liquid intercellular matrix.Because the formed elements are heavier than the liquid matrix, they are packed in the bottom of the tube by the centrifugal force. are solved by group of students and teacher of Class 10, which is also the largest student community of Class 10. Composition of Blood. 7-8% of human body weight is from blood. So, total blood is about 60-80 ml/kg of body weight. Blood absorbs oxygen from the lungs and transports it to different cells of the body. Describe its composition.? 10. The diastolic pressure is always lower than the systolic pressure. Plasma is a liquid also known as the fluid matrix and consists of three types of cells that keep floating in it namely red blood cells, white blood cells, and platelets. They are colourless because it is devoid of haemoglobin. It makes up 8% of our body weight. 3 /mm. The protein in plasma includes antibodies to assist in the body’s defence system against disease and infection. RBCs are produced in the spleen and the bone marrow and live for about four months because they lack a nucleus. These white blood cells have the ability to be stained when exposed to basic dyes, hence referred to as basophil. Blood: Its Composition and Function The blood in our circulatory system is a watery based fluid and consists of two basic components: 1) Plasma (55%) and, 2) Formed elements (45%) Part A: Plasma The Plasma is the light yellow liquid portion of the blood and is about 90% It is responsible for giving blood a characteristic red appearance. They are tiny, circular or oval colourless cells formed in the bone marrow. Blood is a connective tissue that helps in the transportation of substances, protects against diseases and regulates the temperature of the body. Very Short Answer Questions.
