In Suriname toad, eggs are taken care by 

zoology frog introduction to reproduction reproductive system in frog frog - digestive system, circulatory system, excretory system and reproductive system

  1. Male

  2. Female

  3. Both A and B

  4. None of the above

Show answer
Correct Option: B
Explanation:
The Suriname toad is morphologically flat and show remarkable parental care. The eggs are taken care by female toad. The female released eggs which get embedded in the skin on her back by the movement of male toad.
So the correct option is 'Female'.

Carotid artery supplies 

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

  1. Oxygenated blood to lungs

  2. Oxygenated blood to intestine

  3. Oxygenated blood to brain

  4. None of these

Show answer
Correct Option: C
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'.

Covering of lungs is

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

  1. Pleura

  2. Pericardium

  3. Epiglottis

  4. Capsule

Show answer
Correct Option: A
Explanation:

Pleura is one of the two membranes around the lungs. These two membranes are called the visceral and parietal pleurae. The visceral pleura envelops the lung, and the parietal pleura lines the inner chest wall. 

Oxygenated blood from lungs is carried to heart by.

  1. Pulmonary artery

  2. Pulmonary vein

  3. Coronary vein

  4. Pre-cavals

Show answer
Correct Option: B

Congestion of lungs is one of the main symptoms in.

  1. Hypertension

  2. Angina

  3. Heart failure

  4. Coronary artery disease

  5. Atherosclerosis

Show answer
Correct Option: C

Lungs lie in the thoracic cavity separated by ............ from the abdominal cavity.

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

  1. Septum

  2. Diaphragm

  3. Thoracic cage

  4. Ribs

Show answer
Correct Option: B
Explanation:

The diaphragm separates the thoracic cavity, containing the heart and lungs, from the abdominal cavity and performs an important function in respiration. As, the diaphragm contracts, the volume of the thoracic cavity increases and air is drawn into the lungs.  It is a dome-shaped sheet of muscle that is inserted into the lower ribs. 

Cluster of air sacs in lungs are called

  1. Alveolus

  2. Bronchi

  3. Braonchioles

  4. Air spaces

Show answer
Correct Option: A

What is dead space air?  

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

  1. Air in the alveoli

  2. Air in the lungs

  3. Air in the pharynx

  4. Air in the trachea and bronchi

Show answer
Correct Option: D
Explanation:

  • Some amount of air remains behind in the various parts of the respiratory tract.
  • The air in the trachea and bronchi (where no diffusion occurs) is called dead space air.
  • The air remaining in the alveoli or air sacs in alveolar air. The maximum volume of air that can be exchanged in one breath in and out is called the vital capacity. It is about 5000ml. 

Therefore, the correct answer is option D.

The amount of volume of air that can be inspired / expired normally is called

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

  1. Tidal volume

  2. Vital capacity

  3. Residual volume

  4. Normal volume

Show answer
Correct Option: A
Explanation:

Tidal Volume (TV) is the amount of volume of air that can be inspired / expired normally.

Vital Capacity is the greatest volume of air that can be expelled from the lungs after taking the deepest possible breath.
Residual volume is the volume of air still remaining in the lungs after the most forcible expiration possible. Hence, option A is correct.

Person living at sea level has _________ lung capacity than a person living at high altitudes. 

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

  1. Smaller

  2. Higher

  3. Equal

  4. None of the above

Show answer
Correct Option: A
Explanation:

A person who is born and lives at sea level will develop a slightly smaller lung capacity than a person who spends their life at a high altitude. This is because the partial pressure of oxygen is lower at higher altitude which, as a result means that oxygen less readily diffuses into the bloodstream. In response to higher altitude, the body's diffusing capacity increases in order to process more air. 

Therefore, the correct answer is option A.
