Which of the following physiological responses occurs in response to a decrease in blood pressure?

a: Producing coagulation factors - This function is associated more with the liver, which produces various clotting factors involved in the coagulation process.

b. Destroying dying red blood cells: The spleen is primarily involved in the destruction of old or damaged red blood cells. It acts as a reservoir for blood, where it filters out old or abnormal red blood cells, recycling their components and removing any potentially harmful substances.

c: Producing leukocytes before birth - Leukocytes (white blood cells) are primarily produced in the bone marrow, not the spleen.

d: Storing glycogen - Glycogen storage is mainly associated with the liver and muscles, not the spleen.

a. Ureters are connected inside the urinary bladder by a two-way valve: The ureters connect to the urinary bladder through openings that act as one-way valves to prevent urine from flowing back into the ureters.

b. Ureters are fibrotic tubes connecting the kidneys to the urinary bladder: Ureters are not fibrotic; they are muscular tubes lined with a mucous membrane that propels urine from the kidneys to the bladder.

c. Ureters are covered by an outer layer of epithelial tissue: The outermost layer of the ureters is actually composed of connective tissue (adventitia), not epithelial tissue.

d. Ureters are extraperitoneal tubular structures: This is correct. Ureters are located outside the peritoneal cavity.
