Deoxygenated blood

  1. Flows to lungs from the left side of the heart.

  2. Flows to lungs from the right side of the heart.

  3. Flows to right side of the heart from the lungs.

  4. Flows to left side of the heart from the.lungs.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Deoxygenated blood leaves the heart, goes to the lungs, and then re-enters the heart. Deoxygenated blood leaves through the right ventricle through the pulmonary artery. From the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
So, the correct option is 'Flows to lungs from the right side of the heart'

In which of the following ways do the veins differ from the arteries in mammals?

  1. Thicker walls

  2. Deeply present

  3. Carry blood away from heart

  4. Internal valves
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Veins have thin walls as compared to arteries and are superficially located. They carry deoxygenated blood towards the heart and have valves which prevent blood from going backward. Arteries are elastic and thick because they need to transport high-pressure blood while in veins blood flows in low pressure. 

So, the correct answer is option D.

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

  1. Veins

  2. Arteries

  3. Capillaries

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • These are blood vessels that take blood back to the heart,  this blood contains less oxygen and is rich in waste products that are to be excreted or removed from the body. Veins become larger as they get closer to the heart. The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.
So, the correct option is 'Veins'.

Blood vessel carrying blood from the lungs to the heart is

  1. Pulmonary artery

  2. Pulmonary vein

  3. Coronary artery

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
A blood vessel carrying blood from the lungs to the heart is pulmonary vein. There are four pulmonary veins, two from each lung that drains into the left atrium of the heart. Pulmonary veins are responsible for carrying oxygenated blood from the lungs back to the left atrium of the heart. This differentiates the pulmonary veins from other veins in the body, which are used to carry deoxygenated blood from the rest of the body back to the heart.
So, the correct answer is 'Pulmonary vein'.

The left auricle opens into left ventricle through an aperture guarded by

  1. Tricuspid valve

  2. Bisuspid valve

  3. Mitral valve

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bicuspid valve is another name for mitral valve. This valve is the valve between the left atrium and the left ventricle of the heart. It is composed of two triangular flaps, that is located between the left atrium and left ventricle and regulates blood flow between these chambers. 
Therefore, the correct answer is option D.

When the right ventricle contract the blood goes into

  1. Aorta

  2. Brain

  3. Pulmonary artery

  4. None
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

During ventricular systole. The pressure increases in the ventricles, thus forcing the oxygenated blood from left ventricle into systemic aorta and deoxygenated blood from right ventricle into pulmonary aorta.

Capillary is defined as.

  1. That connects the artery and vein

  2. That connects the artery with lymphatic vessel

  3. That connects arteriole with venule

  4. That connects venule with lymph vessel
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Capillaries are microscopic vessels that form a network connecting arterioles (small arteries) to venules (small veins). This connection allows for the exchange of materials between the blood and the surrounding tissues.

Which of the following has least urea?

  1. Pulmonary vein

  2. Hepatic portal vein

  3. Hepatic vein

  4. Renal vein.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The renal vein carries blood away from the kidneys after it has been filtered. Since the kidneys remove urea from the blood, the renal vein contains the lowest concentration of urea compared to other major vessels.

Adventitia is outermost coat of.

  1. Stomach

  2. Intestine

  3. Rectum

  4. Artery
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The tunica adventitia (or tunica externa) is the outermost connective tissue layer of blood vessels, particularly arteries and veins. While other organs have outer layers, the term is most characteristically associated with the histology of blood vessels.

Maximum amount of oxygen is lost from blood in.

  1. Arteries of body

  2. Capillaries surrounding the alveoli

  3. Left auricle of heart

  4. Capillaries surrounding the tissues
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Oxygen is delivered to body tissues through systemic capillaries. As blood passes through these capillaries, oxygen dissociates from hemoglobin and diffuses into the cells, resulting in a significant loss of oxygen from the blood.
