The Correct Option is C

Solution and Explanation

Mitral valve (Bicuspid valve) is present in the atrioventricular opening between the left auricle and left ventricle. During atrial systole, the mitral valve opens to allow the flow of blood from left auricle to left ventricle. During beginning of ventricular systole, mitral valve closes so as to prevent the backward flow of blood.

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.

The different types of body fluids:

Blood

The main components of blood involve;

  1. Plasma
  2. Red Blood Cells
  3. White Blood Cells
  4. 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
