Verified By Collegedunia

The Correct Option is A

Solution and Explanation

ABO blood groups are determined by the gene I (isoagglutinin). There are three alleles, IA, IB and 1� of this gene. IA allele is responsible for formation of A antigen, while IB allele is responsible for formation of B antigen. People with blood group A have the A antigen on the surface of their RBCs, and antibodies to antigen B in their plasma. Persons with blood group B have B antigen on their RBCs, and antibodies against A antigen in their plasma. Individuals with AB blood group have both antigen A and B on their RBCs, and no antibodies for either of the antigen in their plasma. Type O individuals are without A and B antigens on their RBCs, but have antibodies for both these antigens in their plasma. Individuals with blood group AB can receive blood of A, B or O group, while those with blood group O can donate blood to anyone.

Body Fluids and Circulation

Liquid substances in the animal or human body are known as body fluids. The human body consists of about 60-67% body fluids. The chief components of the human body fluids are blood and lymph. Blood comprises a matrix called plasma with blood corpuscles floating in it. The blood cells are white blood cells, red blood cells, and platelets. Lymph consists of lymph cells.

Types of Body Fluids:

The different types of body fluids:

Blood

The main components of blood involve;

Plasma
Red Blood Cells
White Blood Cells
Platelets

Lymph

A colorless fluid present in the interstitial tissues is lymph. It circulates all over the lymphatic system. It can be described as blood without the RBCs. The exchange of hormones, nutrients, and gases occurs via this fluid. It contains lymphocytes that play a major function in the immune responses of the body.

The movement of blood across the vessels of the body that carries nutrients and gases along with it and removes waste from the different parts of the body is circulation.

Types of Circulatory Systems:

There are two types of circulatory systems:

Open Circulatory system
Closed circulatory system
