Describe the "theme" of kidney function in a single sentence and list the components of this functional theme.
To review:
The theme of the kidney function in one sentence and the components involved.
Introduction:
The kidneys are the bean-shaped structures located below the rib cage, one on each side. The kidneys are a part of the excretory system which also includes the ureters and the bladder. The basic structural and functional units of the kidneys are the nephron. The kidneys have medulla and cortex structure, the medulla is the internal part of the kidney whereas, the cortex is the external part of the kidney.
Explanation of Solution
Explanation:
The function of the kidneys can be described in one sentence as ‘controlling the extracellular fluid environment’ within the body. This function is achieved by the urine formation in which the kidneys control various aspects such as blood plasma volume, electrolyte concentration, and so on. The kidneys also release erythropoietin which triggers red blood cell production.
The components of this theme of the kidneys include the following:
1. The volume of the blood plasma which also plays role in the regulation of blood pressure.
2. The amount of waste products in the plasma.
3. The concentration of electrolytes such as sodium ions, potassium ions, and others in the plasma.
4. The pH (potential of hydrogen) of the plasma.
