What is the primary effect of histamine?

A. Bowman's capsule is the site of initial filtration in the kidney, where blood plasma is filtered into the nephron. However, it does not participate in the reabsorption of water.

B. The proximal convoluted tubules are where the majority of water, along with glucose, amino acids, and ions, is reabsorbed. This segment is crucial for maintaining fluid balance in the body.

C. The renal pelvis is a funnel-like structure that collects urine from the collecting ducts and channels it into the ureter for excretion. It does not play a role in reabsorption.

D. The ascending loop of Henle is primarily involved in the reabsorption of salts (sodium and chloride), but not water, as it is impermeable to water. Water reabsorption occurs in other parts of the nephron, such as the proximal convoluted tubule and the descending loop of Henle.

A. Generating and transmitting impulses is the primary function of nervous tissue, not connective tissue. Nervous tissue is responsible for carrying signals throughout the body.

B. Covering and lining body surfaces is the function of epithelial tissue, which forms the skin and the lining of organs, not connective tissue.

C. Contracting and bringing about movement is the function of muscle tissue, not connective tissue. Muscle tissue is responsible for contraction and body movement.

D. Connective tissue's main function is to bind other tissues together and provide structural support. It includes tissues such as bone, blood, cartilage, and tendons, all of which help support, protect, and connect other tissues and organs.
