Which of the bone structures protect the lungs in our body?

  1. Rib cage

  2. Skull

  3. Vertebral column

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

All human beings respire air through the process of inhalation and exhalation. That is inhaled passes through the entire respiratory tract and reaches the lungs. Lungs are respiratory organs located in the thoracic cavity of our body.  The partial pressure of the air inside the lungs guides the process of inhalation and exhalation. They are surrounded by ribs. Ribs are bones that together form the rib cage in our thorax. The rib cage protects the lungs.

So, option A "Rib cage" is the correct answer.

A Correct answer
Explanation

The backbone or vertebral column or spine is a part of the axial skeleton. The backbone is made up of the bones, muscles, tendons, and other tissues that reach from the base of the skull to the tailbone. The backbone encloses the spinal cord and the fluid surrounding the spinal cord.

The most appropriate answer is that the vertebral column is made up of bones.

The enclosed body part below the stomach is occupied by

  1. Ribcage

  2. Pelvic bones

  3. Shoulder bones

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • The stomach is a muscular organ located on the left side of the upper abdomen.
  • The bones of the pelvis or pelvic bones are the hip bones, sacrum, and coccyx. Each hip bone contains three bones— the ilium, ischium, and pubis.
  • The pelvis  It's located between the abdomen and the legs. This area provides support for the intestines and also contains the bladder and reproductive organs.
  • Hence The enclosed body part below the stomach is occupied by the pelvis.
  • So, the correct answer is 'Pelvis'.

Human vertebral column has

  1. Four curves

  2. No curves

  3. Three curves

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

  • The vertebral column in adults have four curvatures and are classified as- primary or secondary curvatures.
1) The primary curves are the ones which are retained from the fetal curvature 
  • It is retained in two regions as the thoracic curve which consists of thoracic vertebrae and the sacrococcygeal curve.
2) Whereas, the secondary curvatures develop gradually after the birth as the child learns to sit upright, stand and walk.
  • The lumbar curve of the lower back is a secondary curvature.
  • So, the correct answer is 'Four curves'.

D Correct answer
Explanation

The breastbone is the flat bone which is located at the center of the chest. Ribs are attached to it forming ribcage. Backbone is the vertebrae extending from the skull to pelvis. The ribs are attached to vertebrae from behind.

Which of the following helps to maintain the structural framework of the body?

  1. Bones

  2. Muscles

  3. Blood

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

The bones and muscles together form the structural framework of the body. The skeleton  constitutes of bones and various types of joints. Muscles are attached to the bones, providing the strength needed for locomotion (movement).

Blood helps to transport gases like oxygen and carbondioxide, hormones, etc. to various parts of the body.
Thus, the bones and muscles together help to maintain the structural framework of the body by providing strength and power to perform work activities.
