In a normal adult human, the average cardiac output (stroke volume) is
- 47 mL
- 70 mL
- 5L
- 3.3L
The Correct Option is B
Approach Solution - 1
Approach Solution -2
The average individual with a weight of 70 kg has a stroke volume of 70 ml.
It is derived from echocardiography, which is a heart ultrasound. The volume of the ventricle is measured here, and the volume of blood in the ventricle at the conclusion of a beat is subtracted.

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
