Multiple choice zoology gas exchange and smoking gas exchange gas exchange in humans respiratory system in humans

What do the trachea and bronchi possess in their wall  of the respiratory tract in man?

  1. C-shaped cartilagenous rings

  2. C-shaped bony rings

  3. V-shaped bony rings

  4. V-shaped cartilagenous rings
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The trachea, primary, secondary and tertiary bronchi, and initial bronchioles are supported by incomplete cartilaginous rings. 


So, the correct answer is 'C-shaped cartilaginous rings'

Lingula structure originates from

  1. Superior side of left lung

  2. Superior side of right lung

  3. Inferior side of right lung

  4. Inferior side of left lung
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • The left lung is divided into two lobes, an upper and a lower, by the oblique fissure, which extends from the coastal to the mediastinal surface of the lung both above and below the hilum.
  •  The left lung, unlike the right, does not have a middle lobe, though it does have a homologous feature, a projection of the upper lobe termed the "lingula". 
  • Its name means "little tongue". Hence, the Lingula structure originates from the Superior side of the left lung.
So, the correct answer is 'Superior side of left lung'.

In nasal passage, the turbinal bones are present in which of the following groups?

  1. In all vertebrates

  2. Amphibia

  3. Mammals

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

In mammals, the nasal chambers are called as nasal vestibules. The nasal vestibules are formed by invagination of skin in embryonic stage and hence nasal vestibules have hair and sebaceous glands. In this manner dust particles cannot cross nasal vestibules. The remaining part of nasal chamber is surrounded by three types of bones- nasal, maxilla and ethmoids. At several places in the nasal passage these bones form outgrowths. These outgrowths are called turbinal bones. Due to these outgrowths, the nasal passage is long and spiral. This helps in making the temperature of air equal to body temperature before it reaches the lungs and does not allows unwanted particles like dust to reach lungs.

Therefore, the correct answer is option C.

Consider the following statements A-D.
A. Epiglottis is the cartilaginous flap of skin which regulates the flow of air into the trachea.
B. Pleura is the ultimate region where in which the diffusion of air between the lungs and blood takes place.
C. Larynx is the voice box, which is the enlarged part of trachea.
D. "Adam's apple" is the protruding cartilage of the voice box of male humans.
The correct and wrong statements are given in

  1. A and B are correct; while C and D are wrong.

  2. B and C are correct; while A and D are wrong.

  3. C and D are correct; while A and B are wrong.

  4. A and D are correct; while B and C are wrong.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The larynx is the voice box, which is the enlarged part of trachea.
"Adam's apple" is the protruding cartilage of the voice box of male humans.
The epiglottis is a flap that is made of elastic cartilage tissue covered with a mucous membrane, attached to the entrance of the larynx. It projects obliquely upwards behind the tongue and the hyoid bone, pointing dorsally. There are taste buds on the epiglottis.
Pleura is one of the two membranes around the lungs. These two membranes are called as the visceral and parietal pleurae. The visceral pleura envelops the lung, and the parietal pleura lines the inner chest wall. There is normally a small quantity (about 3 to 4 teaspoons) of fluid that is spread thinly between the visceral and parietal pleurae. The pleural fluid acts as a lubricant between the two membranes.
So, the correct answer is option C.

Name the organ which divides to form bronchi. 

  1. Larynx

  2. Nose

  3. Tubes

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

A trachea is a connects the larynx and the lungs. It is made up of cartilaginous rings which prevent it from collapsing. It divides into bronchi which further separates to form bronchioles and terminates into air filled lobes known as alveoli.

So, the correct answer is option D.

Multiple choice zoology gas exchange and smoking gas exchange gas exchange in humans respiratory system in humans

One of the following is a difference between pulmonary respiration of frog and human.

  1. Diaphragm and ribs play role in respiration

  2. Lungs are respiratory organs

  3. Respiration occurs due to pressure gradient

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

Humans use a diaphragm and rib cage muscles for ventilation (negative pressure breathing), whereas frogs use a buccal pump mechanism and lack a diaphragm.

Trachea is lined with incomplete rings of

  1. Fibrous cartilage

  2. Calcified cartilage

  3. Elastic cartilage

  4. Hyaline cartilage
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The trachea is also called as windpipe. It is a cartilaginous tube which connects pharynx and larynx to the lungs, allowing passage of air. The wall of the trachea is lined by C shaped incomplete cartilaginous rings to protect it from collapsing during the breathing process due to pressure exerted on its walls by the air. These incomplete rings are made up of hyaline cartilage.
So, the correct answer is 'Hyaline cartilage'.

Choose the correct answer from the alternatives given.
The is an airway that connects the nose and mouth with the

  1. oral cavity; larynx

  2. trachea; pharynx

  3. pharynx; trachea

  4. pharynx; larynx
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The trachea or the windpipe is an airway that is a cartilaginous tube that connects the pharynx and larynx to the lungs, allowing the passage of air. It connects the nose and the mouth with the pharynx and larynx. So, the correct option is 'pharynx; larynx'.

Choose the correct answer from the alternatives given.
Simple squamous non-ciliated epithelium is found in

  1. alveoli

  2. bronchi

  3. bronchioles

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

Simple squamous non-ciliated epithelia are found in capillaries, alveoli, and other tissues where rapid diffusion is required. Cells are flat with flattened and oblong nuclei. It is also called pavement epithelium due to its tile-like appearance. The bronchi are lined by ciliated, pseudostratified columnar epithelium and bronchioles are lined by simple cuboidal epithelium. So, the correct option is 'alveoli'.

Multiple choice biology classification of living organisms binomial nomenclature nomenclature of organisms naming of the organisms nomenclature in classification

In zoological name of an organism the first word will be

  1. Generic name

  2. Specific name

  3. Name of the order

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

In the Binomial system of nomenclature zoological name of an organism consist of two parts. The first part starts with a capital letter and represents genus, the second name that does not start with the capital letter is species name. Both the names are underlined separately.

So, the correct answer is option A.

Multiple choice biology human brain and sense organs introduction to sense organs eyes and their function the structure and function of the eye

Suspensory ligaments are found in

  1. Brain

  2. Eye

  3. Ear

  4. Kidney
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Many suspensory ligaments are attached radially around the lens that serve to pull the edges of lens edges toward the outer circle of the eyeball. They maintain the relatively flat shape of the lens under normal conditions of the eye.
