Human Circulatory System Questions

Multiple choice botany leaf - external morphology venation arrangement of leaves morphology of leaf

Veins are _________ strands on the lamina.

  1. Conducting

  2. Transpirational

  3. Exceptional

  4. Flattened
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Veins provide support for the leaf and transport both water and minerals (via xylem) and food energy (via phloem) through the leaf and on to the rest of the plant and hence are conducting in their function.

So, the correct option is 'Conducting'.

Multiple choice zoology breathing and respiration regulation of breathing human respiratory system contro and disorders of respiration

Carotid artery supplies 

  1. Oxygenated blood to lungs

  2. Oxygenated blood to intestine

  3. Oxygenated blood to brain

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

There are two types of the carotid artery; one in left and one in the right. The external carotid artery supplies blood to the face and neck whereas internal carotid artery supplies blood to the brain.


Therefore the right option is 'oxygenated blood to brain'.

Multiple choice zoology the respiratory system regulation of breathing human respiratory system contro and disorders of respiration

Oxygenated blood from lungs is carried to heart by.

  1. Pulmonary artery

  2. Pulmonary vein

  3. Coronary vein

  4. Pre-cavals
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The pulmonary vein is unique because it carries oxygenated blood from the lungs back to the left atrium of the heart. The pulmonary artery carries deoxygenated blood away from the heart to the lungs.

  3. Blood

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

The Cori cycle (lactic acid cycle), refers to the metabolic pathway in which lactate produced by anaerobic glycolysis in the muscles moves to the liver and is converted to glucose, which then returns to the muscles and is metabolized back to lactate.

State whether the following statements are true or false.
Transfusion tissue is the substitute of lateral veins as it helps in the conduction of water.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Answer A: True
Transfusion tissue immediately surrounding at least part of the vascular bundles in the leaves of gymnosperms, e.g. Pinus. Transfusion tissue is composed of tracheids (transfusion tracheids) with conspicuous bordered pits , and parenchyma cells (transfusion parenchyma) containing tannin-like substances and sometimes starch. The main function of the transfusion tissue is believed to be the transport of materials between the vascular bundles and the mesophyll.

Multiple choice evs circulation of blood blood transfusion transfusion of blood blood and organ donation

Pulse is a wave contraction transmitted along the

  1. Veins

  2. Arteries

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The arterial pulse is a measurement of the heart’s contraction rate because a pulse wave is created when the left ventricle contracts. The arteries expand in response to this contraction and increase in volume. Once expanded, the arteries will contract forcing blood to circulate to the capillaries and then to the veins. The arterial pulse is evaluated for the contour of the pulse wave and its volume, rate and rhythm. The carotid pulse is the most accurate reflection of central aortic pulse. Thus, option B is correct. 

Multiple choice evs circulation of blood blood transfusion transfusion of blood blood and organ donation

Pulse can be palpated from 

  1. Carotid artery

  2. Radial artery

  3. Femoral artery

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pulse is a pressure wave that travels through the arteries after each ventricular systole. The pulse can be felt in any artery that lies near the surface of the body. Carotid artery (neck region), radial artery (forearm) and femoral artery (legs) all of them are situated near the surface of the body. Thus pulse can be palpated from all of them.

So, the correct answer is option D.

In case of bleeding, .......... the affected part to minimise gravitational outflow of blood.

  1. Lower

  2. Raise

  3. Horizontal

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In the case of bleeding, raise the affected part to minimize gravitational outflow of blood. Wash the cut surface with clean water, press the area with a piece of clean cotton wool, and if possible apply some mild antiseptic. Thus, the correct answer is option B.

Multiple choice zoology excretion and osmoregulation micturition urine and urine formation urine formation

Angiotensin - II causes 

  1. Contraction of vascular musculature

  2. Release of aldosterone from cortex

  3. Dilation of blood vessels

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

Angiotensin is a peptide hormone that causes vasoconstriction and an increase in blood pressure. It is part of the renin–angiotensin system, which regulates blood pressure. Angiotensin also stimulates the release of aldosterone from the adrenal cortex to promote sodium retention by the kidneys.


So the correct option is 'Both A & B'.

The different types of the blood vessels seen in the body are

  1. Three

  2. Two

  3. Four

  4. Five
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
There are three different types of blood vessels in the body namely arteries, veins and capillaries. Arteries are the blood vessels which carry blood away from the heart while veins carry blood towards the heart. Capillaries are the smallest blood vessels which connect arteries and veins. 
Therefore, the correct answer is option A.
Multiple choice biology life processes: control and coordination structure and function of brain human brain nervous and endocrine system in humans
Which of the following is richly supplied with blood capillaries?

  1. Duramater

  2. Arachnoid

  3. Piamater

  4. Epidermis
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The meninges are the layers that are closely present around the brain. The dura mater is an outermost tough and fibrous layer. It is followed by the arachnoid mater that forms the middle meninx. The piamater is the innermost meninx which adheres closely to the surface of the brain. It is highly vascular due to the rich supply of the blood vessels. So, it provides oxygen and nutrients to the cells of the brain.

Hence, the correct answer is 'Piamater'

Multiple choice biology nervous system of man human nervous system the structure of brain the human brain

Which of the following is a richly vascular layer with lots of blood capillaries?

  1. Dura mater

  2. Pia mater

  3. Epidermis of skin

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

The pia mater of the brain is the innermost of the three membranes, that cover it. It is the vascular membrane of the brain. It carries the minute branches of the two internal carotids and the two vertebral arteries. It also returns the blood to the heart. The dura mater is the most external membrane of the brain. It forms the internal periosteum of the skull. The dura mater is a dense, tough, inelastic fibrous membrane. The epidermis contains no blood vessels, and cells in the deepest layers are nourished by diffusion from blood capillaries extending to the upper layers of the dermis. So, the correct answer is option B.

  1. Fibroblast growth factor

  2. Epidermal growth factor

  3. Glial growth factor

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer

Blood clot inside a blood vessel is called as

  1. Thrombosis

  2. Agglutinin

  3. Clot

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

The blood clot formed inside the blood vessel is called as a thrombus. When this thrombus breaks and travels to different parts of the body, then it is called embolus. Agglutinin is responsible for the agglutination.

Hence, the correct answer is 'Thrombus'
