Final answer:
The section of the tubule connected to the glomerulus is the proximal convoluted tubule (PCT), which emerges directly from the Bowman's capsule and is the first part of the renal tubule where the filtration from the glomerulus enters, making answer D correct.
Step-by-step explanation:
The section of the tubule that is connected to the glomerulus is the proximal convoluted tubule (PCT). The renal corpuscle consists of the glomerulus and the Bowman's capsule, which surrounds the glomerulus. The PCT emerges directly from the Bowman's capsule and is the first part of the renal tubule where the filtration from the glomerulus enters. Therefore, the correct answer to the provided question is D. Proximal convoluted tubule.
Further along the nephron, following the PCT is the loop of Henle, which descends into the renal medulla and then ascends back into the renal cortex to become the distal convoluted tubule (DCT). The DCT eventually empties into the collecting ducts. The related capillary network within the nephron includes the afferent arteriole that brings blood to the glomerulus, the glomerular capillary bed within the glomerulus, and the efferent arteriole that carries blood away from the glomerulus to form the peritubular capillaries, which surround the renal tubule.
