Facts About Blood

Facts About Blood: Blood is the body fluid which is also one type of connective tissue. It delivers the essential nutrients to the different parts of our body. The types of blood are red blood cells, white blood cells, and platelets. The function of blood includes transferring oxygen and removing carbon dioxide and water materials from our bodies.

The blood cells carry different types of hormones and immune cells to fight against different types of infections.  In this article, we are going to discuss the different facts about blood in detail. 

What is Blood?

Blood is a connective tissue of our body that is made up of different liquid and solid components. The liquid part of the blood is plasma which is made up of water, fat, protein, sugar, and salts. It transports different types of blood cells, hormones, and nutrients to the different parts of our body. On the other side, the solid part of the blood contains red blood corpuscles, white blood corpuscles, and platelets.  

Types of Blood Cells

The various types of blood cells are:

• Red Blood Cells (Erythrocytes): Responsible for carrying oxygen from the lungs to the body tissues and carbon dioxide back to the lungs.
• White Blood Cells (Leukocytes): Part of the immune system, these cells defend the body against infections and foreign invaders.
• Platelets (Thrombocytes): Essential for blood clotting.

Facts About Blood

Let us discuss some major facts of the blood as mentioned below.

Fact 1: Relation With Body Weight

The blood makes up 7 % of our whole body weight. A newborn has around one cup of blood in their body while an adult contains around 5 liters of blood in their body.

Fact 2: Blood Components

There are two types of major components present in our blood including plasma and blood cells. The plasma is made up of water, salts, and different types of proteins. The solid parts contain different types of blood cells including red blood cells, white blood cells, and platelets.

Fact 3: Blood Functions

Blood is the major connective tissue of our body. It transports oxygen and nutrients to the lungs and tissues. The blood transports the antibodies to fight against the infection and also carries the waste materials from the kidney and liver. It also regulates our body temperature.

Fact 4: Inheritance Is Related With Blood

There are different types of blood types including A, B, AB, or O which is able to say about the blood type of our father and mother. 

Fact 5: Red Blood Corpuscles

Red Blood Corpuscles carry oxygen to our whole body by taking it from the lungs. It also collects the carbon dioxide from the cells and carries it back to the lungs. 

Fact 6: White Blood Corpuscles

The White Blood Corpuscles fight with the infections. Different types of White Blood Cells help our body to fight viral, bacterial, and fungal infections. 

Fact 7: Longevity of Red Blood Cells

Red Blood Cells can live for 120 days. There is a respiratory pigment in human blood which is a protein also known as hemoglobin. 

Fact 8: Healthy Red Blood Cells

Iron-rich foods help us to maintain healthy red blood cells. Vitamins B2, Vitamins B12, and Vitamins B3 are essential for our blood.

Fact 9: pH of Blood

The pH of human Blood is around 7.35–7.45. Around 60 percent of human blood consists of plasma and 40 percent is found in the form of blood. 90 percent of the plasma consists of water. 

Fact 10: Human Blood Pressure

The normal blood pressure of a human is 120/80 or lower. It can change in a whole day based on our daily activities. Higher blood pressure may cause so many health problems like stroke, heart attack, and different heart diseases.

Fact 11: Blood Cycle

Each blood cell takes around 60 seconds to complete one cycle in our body. In each heartbeat, our heart can produce 70 milliliters of blood pump. In a normal condition, the human heart bets 70-72 times in a minute.

Functions of Blood

Here are some major functions of the blood as mentioned below. 

• Blood transports oxygen and different types of nutrients to the different cells of our body.
• It also collects the carbon dioxide from the body and transports it back to the lungs.
• Blood also transports the different types of hormones to the different parts of our body.
• Blood helps us to maintain our body temperature and pH levels. It also helps to regulate the water balance by transferring it from the tissues. 
• Blood also carries the different antibodies that can fight the infections. It helps us to prevent the blood loss by forming clots. 

Conclusion – Facts About Blood

Blood is a connective tissue of our body that is made up of different liquid and solid components. The blood also transfers the oxygen to our cells and removes the carbon dioxide and water materials from our body. There are different types of blood cells and they play their major roles to balance our body. In this article, we have learned about the different facts of the blood in detail.
