Blood is a fluid that transports oxygen and nutrients to cells and carbon dioxide, and other waste products.
Blood is a tissue made up of 80% water and 20% solid.
The tissues are mostly made of plasma that contains crucial components like proteins, glucose, and salts to carry nutrients to the body’s different cells. It strengthens the body’s immune system and fights against infections or diseases in our body.
Blood helps our body to maintain optimal temperature. It carries hormones to the body cells and helps in healing of wounds, by clotting the wound with a unique component called platelet.
Blood comprises three major components: white blood cells, red blood cells, and platelets, and contains fats, sugar, carbohydrates, proteins, hormones, and salts.
There are four main types of blood. However, they are distinguished into 8 types of blood or blood groups based on the presence and absence of antibodies and inherited antigenic substances from the parents.
1. What is blood? Explain?
Blood is the liquid substance that flows in our body through veins and arteries. It is generated from the bone marrow and pumped by the heart to different body parts. Blood is red and transports oxygen and nutrients to the body cells. The color of the blood is red due to a unique substance or pigment called hemoglobin.
2. What are the three types of blood?
The three types of blood are; Platelets, White blood cells (WBC), and Red blood cells (RBC).
3. What are the 8 types of blood?
The 8 types or group of blood are O (positive), O- (negative), A (positive), A- (negative) B (positive), B- (negative), AB (positive) and AB- (negative).
4. What are the functions of WBC?
White blood cell or WBC helps the immune system fight against antibodies and infectious diseases.
5. What are the 6 types of anemia?
The most common six types of anemia are:
6. What is the fastest way to cure anemia?
Anemia is a disease or a deficiency caused by less hemoglobin in red blood cells in the body. Blood transfusion and bone marrow transplant are the fastest ways to heal to cure anemia. But, the treatment varies with the types of anemia an individual suffers from.
For example, a person with iron-deficiency anemia should take iron supplements and change their diet. A person with aplastic anemia should go for blood transfusion and medication or a bone marrow transplant.
7. What kills red blood cells?
Many agents could kill or minimize the number of red blood cells in our body. An agent or antibodies like snake venom, toxic chemicals, and malaria could kill red blood cells in the body. Chemicals in medicine like penicillin can also kill RBC. Daily exercise is good for the body, yet excessive exercise could also kill red blood cells.
8. How many colors of blood are there?
There are five different colors of blood depending upon the animal’s presence and absence of pigment. They are red, blue, green, yellow and orange.
9. What are the fastest ways to increase red blood cells?
There are many ways to enrich RBCs in our bodies. Maintaining a good diet, such as eating iron-rich food, can quickly increase the production of red blood cells.
