Body fluids are the terms related to our body. Fluids here means the liquid-like substance that is produced in the body and then circulated to all other parts of the body.There are mainly two important fluids in the human body. They are blood and lymph. Blood is a fluid which is comprised of plasma, white blood cells, red blood cells, and platelets. Whereas lymph is a colourless fluid that circulates inside the lymphatic vessels. Lymph is also known as interstitial fluid and tissue fluid.
Components of blood
The important functions of body fluids are mentioned. They help in the transportation of oxygen and nutrients to all the parts of the body and excrete the waste materials from the body. They also help in regulating the body temperature and maintaining an efficient metabolism of the body. Circulation is a process through which blood moves with the help of vessels. The vessels carry all the important nutrients and gases throughout the body. So that the body can function properly.
MCQs on Body Fluids and Circulation
Ques 1. Due to which condition blood clot forms in the circulatory system.
- Hematoma
- Thrombus
- Strombus
- None of the above
Click here for the answer
Answer: b. Thrombus
Explanation: In the circulatory system where blood clots form due to the thrombus. The thrombus sticks to the place in which it is formed. So, they prevent blood flow. The thrombus can be formed due to various medical problems like internal injuries in veins and arteries, lack of movements in the body. Those people who are suffering from cancer, obesity, liver and kidney problems are more prone to this condition of blood clotting.
Ques 2. What are the composition of blood?
- Red Blood Cells
- White Blood Cells
- Plasma and Platelets
- All of the above
Click here for the answer
Answer: d. All of the above
Explanation: Blood is a fluid produced in our body. The blood is composed of red blood cells, white blood cells, platelets and plasma. The blood is an important fluid in the human body because it transports oxygen and other nutrients to all parts of the body. It also helps in the excretion of carbon dioxide and waste materials out of the body. All four components of blood are responsible for different functions in our body.
Ques 3. When a person suffers from trauma then there is excessive loss of blood and this condition is called?
- Exsanguination
- Haemolysis
- Concussion
- Thrombosis
Click here for the answer
Answer: a. Exsanguination
Explanation: Exsanguination is a condition in which excessive loss of blood occurs. This condition is fatal to the body when not treated quickly. The condition happens when the heart can not be able to pump blood throughout the body. When almost one-fifth of the blood loss from the body then Hemorrhagic shock begins which can lead to death if not treated soon.
Ques 4. Which type of blood disorder is responsible for haemoglobin's defectiveness?
- Haemolysis
- Alopecia
- Heterochromia
- Sickle cell anaemia
Click here for the answer
Answer: d. Sickle cell anaemia
Explanation: Sickle cell anaemia is a serious blood disorder in the blood cells. It is a hereditary disease. The red blood cells are affected by the occurrence of this disorder. During this problem, the hemoglobin present in RBCs becomes defective and changes into an irregular shape. The defective hemoglobin is called (HgbS). The red blood cells become rigid or solid. Sickle cell anaemia is a fatal disorder and cannot be treated.
Ques 5.Which blood vessel is responsible for carrying the deoxygenated blood into the lungs from the right ventricle.
- Pulmonary vein
- Pulmonary artery
- Aorta
- None of the above
Click here for the answer
Answer: b. Pulmonary Artery
Explanation: The pulmonary arteries carry blood to the lungs from the right side of the heart. The heart has four chambers in it. They are the right atrium, right ventricle, left atrium and left ventricle. So the blood moves from one part to another. The deoxygenated blood comes back from the body to the right atrium. From the right atrium, it enters into the right ventricle. Hence, the heart pumps it to the lungs through the main pulmonary artery.
Ques 6. When blood vessels get damaged, which cell is responsible for the formation of clots?
- Cellulose
- Platelets
- Haemoglobin
- None of the above
Click here for the answer
Answer: b. Platelets
Explanation: Platelets are the type of blood cells which are smaller in size. In the human body when the blood vessels get damaged it forms blood clots to stop bleeding. Suppose the blood vessels get damaged in the body it quickly gives out some signals to the platelets. Hence, when the platelets receive these signals, they move to the site of damage. After they form blood clots to repair the damage.
Ques 7.Which is a small branch of an artery that opens up into the capillary tube?
- Capillaria
- Areolas
- Arteriole
- None of the above
Click here for the answer
Answer: c. Arteriole
Explanation: Blood is a fluid which circulates through all parts of the body. The blood is carried through various vascular tissues.They are arteries, veins, and capillary beds. The artery carries blood to other parts from the heart. Having small branches in it, named arterioles, is responsible for distributing that blood into all the other parts of the body. These arterioles then open up into the capillary tube. The arterioles have tiny vessels in it.
Ques 8. What is the difference between systolic pressure and diastolic pressure in a human?
- 40 mm Hg
- 20 mm Hg
- 50 mm Hg
- None of the above
Click here for the answer
Answer: a. 40 mm Hg
Explanation: The difference between systolic pressure and diastolic pressure is 40 mm Hg. Blood pressure is defined as the force of blood against the arteries. This is said that the human should maintain a normal blood pressure range between 90 – 120 / 60 – 80 mm Hg. So whenever the Blood pressure is checked the numbers denote the level of blood pressure in the body.
Ques 9. What is the normal diastolic blood pressure in a healthy human being?
- 80 mm Hg
- 70 mm Hg
- 100mm Hg
- 110 mm Hg
Click here for the answer
Answer: a. 80 mm Hg
Explanation: The normal range of diastolic pressure in a healthy human being is 80 mm Hg. Diastolic pressure is a blood pressure occurs in the arteries when the heart rests between beats. It maintain a normal level of systolic pressure and diastolic pressure. Hence, the normal range for diastolic pressure is 80 mm Hg.
Ques 10. How many types of blood groups are found in the human body?
- Three
- Four
- One
- Five
Click here for the answer
Answer: b. Four
Explanation: There are four main types of blood groups are found in the human.The types of blood groups are – A, B, AB and O.The blood group is determined by genes which are inherited from our parents. Each group of blood can be either RhD positive or RhD negative.This means the total number of blood groups are eight. Red blood cells contain a protein named RhD antigen. Due to the presence of the protein, the blood group will be positive and due to absence it will be negative.
