Answer 2

Well, blood (to my knowledge) consists of four parts: Red Blood Cells White Blood Cells Plasma Platelettes The red blood cells carry oxygen throughout the body which is helpful in maintaining a good immune system. The plasma is the fluid in which the blood cells travel. In this fliud are also call platelettes, which activate when there is a cut on the skin. They clot up at the opening to keep any harmful bacteria from entering the body. And finally, the most important cell, the white blood cell. White blood cell are essential in fighting off harmful bacteria in the body in defensive for your immune system. When bad bacteria is present in the body, the white blood cells release an antibody that destroys them and then the white blood cells break down the bacteria.

Answer 3

1.Blood carries oxygen from the lungs to all the other tissues in the body and, in turn, carries waste products, predominantly carbon dioxide, back to the lungs where they are released into the air.
2. Food that has been processed by the digestive system into smaller components such as proteins, fats, and carbohydrates is also delivered to the tissues by the blood. These nutrients provide the materials and energy needed by individual cells for metabolism, or the performance of cellular function.
3. Waste products produced during metabolism, such as urea and uric acid, are carried by the blood to the kidneys, where they are transferred from the blood into urine and eliminated from the body.
4. In addition to oxygen and nutrients, blood also transports special chemicals, called hormones, that regulate certain body functions. The movement of these chemicals enables one organ to control the function of another even though the two organs may be located far apart.
5. In this way, the blood acts not just as a means of transportation but also as a communications system.

Answer 4

it is a major part of the circulatory system and it helps in various functionbs such as transportation of food and hormones which are directly given into the blood stream and one of the most important things that blood contains is platelets which help in blood clotting if they were not there we would all bleed to death at even the most minor cuts blood even contains red blood corpucels and white blood corpucels which carry oxygen and fight against bacterial activities respectively.
hope this has answered ur question

Answer 5

Blood is mainly transporter of gases, nutrients, excretory product, hormones, drugs, etc.It provides a source of antibody production, which is related to immunity, that is, defense of the body against foreign substances.It helps in wound healing. Blood is a mirror of the body as it enables a doctor to diagnose a disease.In intrauterine life, blood is the main connecting link between the fetus and the mother for all the needs.

Answer 6

As blood itself has many functions in the body but the main function is to transport matereals in and out of the cells of a living organism such matereals can either be blood,digested food,water and other things the blood also helps in fighting against diseases as it contains white blood cells which act as the body immune system and though it is in liquid form but it also provide a meddium in which it helps it self in clotting when there is any injure in the body ity also helps in transporting oxygen to the heart and out of the heart

Answer 7

blood is essential component in our body.it has various components that serves some or the other purpose-
like haemoglobin carries oxygen and supplies to all body parts,white blood cell fights germs and external agents that may harm body,fibrinogen helps repair ruptured blood vessel,blood also carries the food component all over the body for assimilation.in short blood is a carrier and indispensible for any body to function normally.

Answer 8

Functions of blood are:
- Supply of oxygen to tissues (bound to hemoglobin which is carried in red cells)
- Supply of nutrients such as glucose, amino acids and fatty acids (dissolved in the blood or bound to plasma proteins)
- Removal of waste such as carbon dioxide, urea and lactic acid
- Immunological functions, including circulation of white cells, and detection of foreign material by antibodies
- Coagulation, which is one part of the body's self-repair mechanism
- Messenger functions, including the transport of hormones and the signalling of tissue damage
- Regulation of body pH
- Regulation of core body temperature
- Hydraulic functions, including erection (see also jumping spider)

Answer 9

It has many roles. It carries nutrients and oxygen to tissue, aids in transporting hormones and antibodies, it transports waste to outlets, plus many more things a doctor will be happy to explain

Answer 10

It is just a transporter of food. You eat by your mouth, but the rest of your body also needs to eat. Without blood, that food (oxygen, mineral salts, organic matter) wouldn't have been transported to your limbs, kidney, even your heart needs blood to survive. (coronary arteries feed it)

Answer 11

Blood plays several parts in the human body such as:
1- Homeostasis (Maintaning the internal environment of the body by maintaning tissue fluid, keeping body temp. constant, etc.)
2-Transport of O2 from Lungs to the tissues
3-Transport of CO2 frm tissues to the lungs
4-Transport of nitrogenous waste frm liver to the kidneys
5-Transport of soluble food frm ileum to liver to general circulation
6-Transport of hormones
7-Protection against infection.
