Weekly Quiz Competition

Question 1
1 / -0

Which of the following is a false statements?

A
ECG is of clinical significance

B
Electrocardiograph is the recording of electrical changes during the cardiac cycle

C
To obtain a standard ECG, a patient is connected to the machine with $$3$$ electrodes(one to each writs and to the left ankle)

D
Normal activities of the heart are regulated intrinsically hence it is myogenic
Question 2
1 / -0

Here human heart and blood vessels are given in the diagram. Arrows drawn shows circulation of blood. What is the best definition for artery and veins by the diagram?

A
Arteries carry blood to the lungs and veins carry blood to the heart.

B
Arteries supply blood to the different parts of the body from the heart and veins carry to heart from the different parts of the body.

C
Arteries carry blood to the heart and veins carry to the different parts of the body blood

D
Arteries carry only Oxygenated blood and veins carry only blood with Carbon dioxide.

Solution

Arteries are blood vessel responsible for carrying oxygen-rich blood away from the heart to the body, except for pulmonary artery that carries deoxygenated blood to the lungs. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for oxygenation. Except for pulmonary vein that carries oxygenated blood from the lungs to the heart.
So, option B is the correct option.
Question 3
1 / -0

Transport of $$CO_2$$ is mainly in the form of

A
Sulphates

B
Phosphates

C
Bicarbonate

D
Chlorides

Solution

The correct answer is C.
Carbon dioxide molecules are transported in the blood from body tissues to the lungs by one of three methods: dissolution directly into the blood, binding to hemoglobin, or carried as a Bicarbonate(Carbonate) ion. 70% of Carbon dioxide is transported as bicarbonates.
Question 4
1 / -0

Identify $$A,B$$ and $$C$$ in the given blood clotting process.
Damage platelets release $$A$$;$$A$$ converts $$D$$ into $$B$$ in presence of Calcium ions. $$B$$ converts $$C$$ into Fibrin thread.

A
A-Thromboplastin,B-Prothrombin,C-Fibrinogen

B
A-Thrombin,B-Fibrinogen,C-Thrombo-kinase

C
A-Thromboplastin,B-Thrombin,C-Fibrinogen

D
A-Prothrombin,B-Thrombin,C-Fibrinogen
Solution
Correct option: C

Explanation:
- In Blood clotting process, Damaged platelets or tissues release thromboplastin (A), which in presence of Ca++ ions causes conversion of prothrombin (D) to thrombin (B).
- Thrombin causes polymerization of fibrinogen (C) to fibrin thread.
  Thus, Option C - "A-Thromboplastin, B-Thrombin, C-Fibrinogen" is correct.
Question 5
1 / -0

Which option is correctly identifying the given formed elements?

A
A-RBC, E-Eosinophil

B
C-Eosinophil, G-B-lymphocyte

C
D-Basophil, F-Monocyte

D
B-Platelets, H- T-lymphocyte

Solution

The correct answer is D.
Platelets have no cell nucleus. They are fragments of cytoplasm that are derived from the megakaryocytes of the bone marrow, which then enter the circulation.
T-cell receptors consist of two polypeptide chains. A typical T cell may have as many as 20,000 receptor molecules on its membrane surface, all of either the alpha-beta or gamma-delta type. T-cell antigen receptor. The basic structure of a typical T-cell antigen receptor.
Question 6
1 / -0

At the end of joint diastole, which condition can be observed in heart?

A
P wave will appear in the ECG

B
Ventricles are about to show systole

C
Ventricles are about three quarters full i.e., $$70$$ percent filling of the ventricles has taken place

D
Both $$(1)$$ & $$(3)$$

Solution

During joint diastole blood is poured into left and right atria. Due to this filling of blood during joint diastole, atrioventricular valves (Bicuspid and Tricuspid valves) open and allows blood to flow from atria to ventricles. During joint diastole there is 70% filling of ventricles. the following is characterized by appearing of p wave in ECG.
Hence, the correct answer is (A)
Question 7
1 / -0

Which of the following system of blood vessels is present in our body exclusively for the circulation of blood to and from the cardiac musculature?

A
Portal system

B
Pulmonary circulation

C
Coronary circulation

D
Both $$(1)$$ and $$(2)$$

Solution

The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. A special coronary system of blood vessels is present in our body exclusively for the circulation of blood to and from the cardiac musculature. Normal activities of the heart are regulated intrinsically, i.e., auto regulated by specialised muscles (nodal tissue), hence the heart is called myogenic.
So, the correct answer is (C)
Question 8
1 / -0

State the true statements of the following:
$$(1)$$ Blood flowing in arteries is without high pressure.
$$(2)$$ Blood flowing in veins is without high pressure.
$$(3)$$ Veins have valves opening towards heart.
$$(4)$$ Arteries have valves opening towards heart.

A
$$1$$ and $$3$$ statements are true

B
$$1$$ and $$4$$ statements are true

C
$$2$$ and $$3$$ statements are true

D
$$1$$ and $$2$$ statements are true

Solution

The correct answer is C.
Veins have wide lumen, so they cannot exert much peripheral pressure on blood flow.
Veins drain into the heart, so they have valves opening towards the heart.
Question 9
1 / -0

Coagulation of blood in blood vessels in living body is prevented by:

A
Prothrombin

B
Heparin

C
Prothrombin and calcium together

D
Plasminogen and calcium together

Solution

Heparin prevents blood coagulation in the blood vessels. It is secreted by mast cells. It is an anticoagulant, blocking the conversion of prothrombin to thrombin. Haemoglobin is the blood pigment necessary for oxygen transport.
Hence the correct answer is (A)
Question 10
1 / -0

The only artery which carries deoxygenated blood is?

A
Hepatic artery

B
Pulmonary artery

C
Aorta

D
Renal artery

Solution

The largest artery is the aorta, which connects to the heart and picks up oxygenated blood from the left ventricle. The only artery that picks up deoxygenated blood is the pulmonary artery, which runs between the heart and lungs. The circulatory system delivers oxygen and nutrients to cells and takes away wastes.
So, the correct answer is (B)
