Body fluids are essential for the smooth functioning of our tissues and carry out the important function of providing living cells with nutrition and eliminating harmful substances produced in our bodies. Different organisms have developed other mechanisms to facilitate these tasks. The study of bloody fluids covers various branches of biology. Complex organisms such as human beings, however, make use of fluids such as blood and lymph in order to execute the aforementioned processes. Here in this blog, we find out more about body fluids and circulation. It is an important part of NCERT Biology Class 11 and will also help you prepare for medical entrance exams such as NEET, JIPMER. This Blog Includes:BloodBefore we find out about body fluids and circulation, let us talk about the most important fluid in our body, blood! Blood is a connective tissue comprising:
We will now talk about these important components of blood. Fluid matrixThe fluid matrix mainly comprises highly specialized cells suspended in the liquid matrix. These cells serve a particular function. The fluid matrix of the cell is also called Plasma. PlasmaPlasma is a viscous fluid that constitutes nearly 50-55% of the blood volume. Plasma consists of
Formed MaterialsFormed elements nearly constitute 45% of the blood. Formed elements are comprised of
Blood GroupsBody fluids and circulation also talks about blood groups. There are two main types of blood groupings done all over the world are ABO and RH. ABO grouping is done on the basis of the presence or absence of antigens in the RBC’s namely A and B. Therefore considering the presence or absence of antigens and antibodies, there are 4 types of blood groups A, B, AB and O. Tabulated below are details about blood groups. Blood GroupAntigens on RBCsAntibodies in PlasmaDonor’s Group A A anti-b A,O B B anti- a B,O AB A, B nil AB,A,B,O O nill anti-a,b OPeople with the O blood group are called Universal Donors because they can give blood to anyone and people with the AB blood group are called Universal Recipients as they can receive blood from any other group. RH GroupRH Groups form an important part of body fluids and circulation. Rh antigen is present in nearly 80% of human beings. Those with the antigen are Rh-positive and those without them are Rh-negative. Here are a few details about RH Groups.
Coagulation of BloodCoagulation of blood is another important aspect of body fluids and circulation. As a mechanism to prevent excessive loss of blood, the blood exhibits coagulation or clotting. Let us find out more about it.
Lymph (tissue fluid)Lymph is also a fluid connective tissue that is released as blood passes through capillaries in tissues. It is essential to find out about lymph in the study of body fluids and circulation. The mineral distribution of this liquid is the same as plasma. It facilitates the exchange of gases and nutrients between the blood and the cells. Lymph contains lymphocytes and is a part of the immune response system. It also carries nutrients, hormones etc. Circulatory PathwayNext in body fluids and circulation, we have the circulatory pathway. Circulatory pathways are mainly of 2 types – open or closed. Open circulatory pathway – Blood vessels are absent, and blood is found in the open cavities/sinuses. The internal organs float in the sinuses. Closed circulatory pathway – There are networks of blood vessels that circulate the blood.

It is situated between the thoracic cavity, between the two lungs. Tilted slightly to the left, a human heart is roughly the size of a fist. Some of the important terms to know of, with respect to the heart are
Cardiac CycleMoving further in body fluids and circulation, we find out about the cardiac cycle. At the start of the cycle, all 4 chambers are in a relaxed state called the joint diastole. Here is how it functions:
ECGECG is a graphical representation of the electrical activity of the heart during a circadian cycle. It is important to have an understanding of ECG to study body fluids and circulation. The ECG machine provides an electrocardiogram.
Double CirculationMoving ahead in body fluids and circulation, let us now find out about double circulation. The blood flows twice through the heart, once in an oxygenated state and the other in a deoxygenated state. This is called Double circulation and includes systematic and pulmonary circulation.
Regulation of Cardiac ActivityNext in body fluids and circulation, we talk about cardiac activity, as cardiac activity helps in pumping blood throughout the body.
Disorder of the Circulatory SystemA disorder in the circulatory system can cause trouble in pumping body fluids and circulation activity in the body. Let us find out about these disorders.

Name the components of the formed elements in the blood and mention one major function of each of them. Answer: The components of the formed elements in the blood are mentioned below:
Q2. What is the importance of plasma proteins? Answer: Below is the plasma proteins with the major function of each of them:
Q3. Match Column I and Column II: Answer: Column I Column IIEosinophils(i) Resist InfectionsRBC (ii) Gas Transport (c ) AB Group(iii) Universal Recipient (d) Platelets(iv) Coagulation (e) Systole(v) Contraction of HeartQ4. Why do we consider blood as a connective tissue? Answer: Blood is a connective tissue that is generated from the mesoderm and contains plasma, an extracellular matrix. It is a plentiful and extensively dispersed tissue throughout the body. Connective tissues connect and bind to other organs in the body, carrying oxygen and other nutrients inside the body, extracting waste products from the body, and enabling blood to flow freely throughout the body. As a result, it is classified as connective tissue. Q5. What is the difference between Lymph and Blood? Answer: The following is the difference between Lymph and Blood Lymph BloodIt is a white tissue fluidIt is a red liquid connective tissueIt flows in the lymph vesselsIt flows in the blood vessels such as capillaries, arteries and veinsIt contains lymphocytes (white blood cells)It contains red blood cells, white blood cells, haemoglobin, plateletsThe exchange between gases and nutrients between the blood and cells takes place through the LymphBlood transport gases and other nutrients to the bodyFAQsWhat is the importance of plasma proteins? Globulins: They are known as defense mechanisms of the body and are also referred to as immunoglobins. What is ECG? ECG is a graphical representation of the electrical activity of the heart during a circadian cycle. It is important to have an understanding of ECG to study body fluids and circulation. The ECG machine provides an electrocardiogram. Why is blood a connective tissue? Blood is a connective tissue that is generated from the mesoderm and contains plasma, an extracellular matrix.

What is the importance of ABO system?The ABO blood group antigens remain of prime importance in transfusion medicine—they are the most immunogenic of all the blood group antigens. The most common cause of death from a blood transfusion is a clerical error in which an incompatible type of ABO blood is transfused.
What is the purpose of ABO blood grouping?For a blood transfusion, the ABO blood group system is used to match the blood type of the donor and the person receiving the transfusion. People with blood type O can donate blood to anyone and are called universal donors. People with blood type AB can accept blood from all donors and are called universal recipients.
Why was the discovery of the ABO system important?The discovery of the ABO system is incredibly important in medicine as it allows for the donation of blood from one individual to another. Before the understanding of blood types, a person with type A blood might receive blood from a person with type B blood.
