Answer (1)
The lungs are two balloon-like body parts that lie in the thoracic cavity.
The thoracic cavity, also known as the chest cavity, is a part of the human body's anatomy. It is the space that contains the lungs and the heart, as well as other important structures like the esophagus and trachea. The lungs allow us to breathe in oxygen and expel carbon dioxide through a process known as respiration.
Joints and muscles help in the movement of the body parts.
Joints are the connections between bones that allow movement and flexibility. Muscles are fibrous tissues that contract and relax to produce movement by pulling on the bones. Together, joints provide the pivot points, and muscles provide the force necessary for moving different parts of the body such as limbs, fingers, and even facial expressions.
There are 206 bones in our body.
The human skeletal system is made up of 206 bones, which provide structure and support, protect our vital organs, and work with the muscular system to enable movement. The number of bones can vary slightly for some individuals if they have certain conditions like polydactyly or accessory bones.
The stomach helps us to digest the food we eat.
The stomach is an organ in the digestive system that uses acids and enzymes to break down food into a semi-liquid form called chyme. This is the initial stage of digestion that occurs after chewing, and the chyme then moves into the small intestine for further digestion and nutrient absorption.
