  1. Male

  2. Female

  3. Both A and B

  4. None of the above

Reveal answer Fill a bubble to check yourself
B Correct answer
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'.
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.

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

Congestion of lungs is one of the main symptoms in.

  1. Hypertension

  2. Angina

  3. Heart failure

  4. Coronary artery disease

  5. Atherosclerosis

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

Congestion of the lungs (pulmonary edema) occurs when the heart cannot pump blood effectively, causing fluid to back up into the lungs. This is a classic symptom of congestive heart failure.

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

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

  1. Septum

  2. Diaphragm

  3. Thoracic cage

  4. Ribs

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

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

What is dead space air?  

  1. Air in the alveoli

  2. Air in the lungs

  3. Air in the pharynx

  4. Air in the trachea and bronchi

Reveal answer Fill a bubble to check yourself
D Correct answer
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.

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

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

  1. Tidal volume

  2. Vital capacity

  3. Residual volume

  4. Normal volume

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

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

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

  1. Smaller

  2. Higher

  3. Equal

  4. None of the above

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