The trachea is the main airway in the human body. It carries air from the larynx to the bronchi in the lungs, allowing for breathing and gas exchange.
The joint action in leg extensions is knee extension, where the angle between the thigh and lower leg decreases. The main muscles involved in this action are the quadriceps, specifically the vastus medialis, vastus lateralis, vastus intermedius, and rectus femoris. The movement primarily occurs at the knee joint.
The main parts of the human body include the head, neck, torso, arms, and legs. Each part serves a specific function in the body's overall movement and functioning.
Human body's main organ of balance is located in internal ear. You have vestibular apparatus with three semicircular canals there. The semicircular canals are placed at right angles to each other.

The antagonists to the quadriceps are primarily the hamstrings, located at the back of the thigh. Their main action is to flex the knee joint, which opposes the quadriceps' action of extending the knee. Additionally, the hamstrings assist in hip extension. This opposing relationship is crucial for balanced movement and stability during activities like walking and running.
The main muscles in the human body include the biceps, triceps, quadriceps, hamstrings, glutes, abdominals, and pectorals. These muscles are responsible for various functions such as movement, stability, and posture. Strengthening these muscles can improve overall physical performance and reduce the risk of injuries.
The main action of the quadriceps or "quads" is walking. This muscle helps straighten the knee and maintain posture. Without this muscle, running, walking, and even standing would be quite impossible.

The main artery in the human body is the aorta. It is the largest in the body and originates from the left ventricle of the heart.
