Which one of the following parts of body does NOT take part in the process of breathing ?

The process of breathing involves the respiratory system, which includes the trachea (windpipe), bronchi, and the diaphragm [6]. The trachea and bronchi serve as conducting passages that transport air into the lungs [4]. The diaphragm is a dome-shaped muscle located below the lungs that contracts and moves downward during inhalation to increase chest volume, allowing air to enter [5]. In contrast, Bowman’s capsule is a cup-shaped structure located in the kidney [4]. It is a critical component of the nephron, the functional unit of the urinary system, where it functions to collect filtrate from the glomerular capillaries during the process of blood filtration and waste excretion [4]. Therefore, Bowman’s capsule is involved in the excretory system rather than the respiratory system and does not take part in the process of breathing [4].
