Squamous epithelium forms inner lining of which of the following?
I. Blood vessels
II. Lung alveoli
III. Salivary duct

  1. I and II only

  2. II and III only

  3. I, II and III only

  4. II and IV only

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Squamous epithelium is a thin, flat layer of cells ideal for diffusion. It forms the inner lining of blood vessels (endothelium) and the alveoli of the lungs, where gas exchange occurs.

The only artery which carries deoxygenated blood is?

  1. Hepatic artery

  2. Pulmonary artery

  3. Aorta

  4. Renal artery

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Arteries normally carry oxygenated blood away from the heart, with the notable exception of the pulmonary artery. The pulmonary artery transports deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.

Choose the correct statement.

  1. More diameter in arteries

  2. Wall are thick in veins

  3. More blood pressure in arteries

  4. Valves present in arteries

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Arteries carry blood under high pressure directly pumped from the heart, requiring them to have thick, elastic walls. In contrast, veins have thinner walls, larger lumens, and valves to prevent backflow.

A red blood cell is located in the artery supplying to right leg, how many capillary beds must this cell pass through before it is returned to the left atria?

  1. One

  2. Two

  3. Three

  4. Four

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A red blood cell in an artery supplying the right leg must first pass through the systemic capillary beds in the lower limb tissues to deliver oxygen. After returning through the systemic veins and right side of the heart, it is pumped through the pulmonary capillary beds in the lungs to get oxygenated before returning to the left atrium, totaling two capillary beds.

Which blood vessels have the smallest diameter?

  1. Capillaries

  2. Arterioles

  3. Venules

  4. Lymphatic

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Capillaries are the smallest blood vessels in the body, with a diameter just large enough to allow red blood cells to pass through in single file. This small size facilitates the efficient exchange of gases, nutrients, and waste products.

A vein differ from an artery in having

  1. Strong muscular walls

  2. Narrow lumen

  3. Valves that control direction of blood flow opposite to heart

  4. Valves that control direction of blood flow towards heart

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Veins drain capillaries in the tissues and organs and return the blood to the heart. Veins have a unique structural feature which is not present in arteries. They are equipped with one way valves, that prevent the back flow of blood.

In which of the following character a vein differs from an artery?

  1. Having valves to control flow of blood

  2. Having narrow lumen

  3. Having muscular wall

  4. Having pigmented wall to give dark look

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Arteries carry blood from the ventricles (pumping chambers) of the heart out to the capillaries in organs and tissue. The smallest arteries are called arterioles.Veins drain capillaries in the tissues and organs and return the blood to the heart. The smallest veins are the venules.
Veins have a unique structural feature not present in arteries. They are equipped with one-way valves that prevent the backflow of blood.

So, the correct answer is option A.

An artery can be distinguished from a vein in having

  1. Thicker wall

  2. Oxygenated blood

  3. More haemoglobin

  4. Both A and B

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • An artery carries oxygenated blood from the heart to different parts of the body. It has thick walls that allow it to withstand the high pressure of the blood.
  • Veins carry the deoxygenated blood from the different parts of the body to the heart which is further carried by the pulmonary artery for oxygenation. The veins have thin and elastic walls.
So, the correct answer is option D.
Multiple choice evs transportation in living organisms circulatory system and organs blood and blood vessels circulatory system blood pressure

Arteries are the

  1. Blood vessels which carry only oxygenated blood

  2. Blood vessels which carry only deoxygenated blood

  3. Blood vessels which carry blood from the heart to different organs of the body

  4. Blood vessels which carry blood from different organs of the body to the heart

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation (usually veins carry deoxygenated blood to the heart but the pulmonary veins carry oxygenated blood as well.
So, the correct option is 'Blood vessels which carry blood from the heart to different organs of the body'.
