Excretory functions consist of the ________________.
- Proximal convoluted tubule
- Glomerular filtration
- Ureteropelvic Junction
- Renal corpuscle
Correct Answer

A. Renal corpuscle

Explanation

The renal corpuscle is part of the excretory system and is responsible for the initial filtration of blood in the kidneys. It consists of the glomerulus, which filters waste products and excess fluids from the blood, and the Bowman's capsule, which surrounds the glomerulus and collects the filtered substances. The proximal convoluted tubule, ureteropelvic junction, and glomerular filtration are all components of the excretory system, but they are not the specific functions that make up the excretory functions.

Rate this question:
21.

What is the first step in the filtration of blood for urine formation? ***
- Bladder
- Renal corpuscle
- Proximal convoluted tubule
- Glomerulus
Correct Answer

A. Glomerulus

Explanation

The first step in the filtration of blood for urine formation is the glomerulus. The glomerulus is a network of capillaries located in the renal corpuscle. It is responsible for filtering waste products, toxins, and excess water from the blood, allowing only essential substances like nutrients and ions to pass through. The filtered blood then moves on to the proximal convoluted tubule for further processing and reabsorption. The bladder is not involved in the initial filtration process.

Rate this question:
22.

Where does the Glomerulus lay?
- Bladder
- Proximal convoluted tubule
- Bowman's capsule

- Proximal convolution, Glomular filtration, tubular secretion
- Tubular reabsorption, Proximal convolution; tubular secretion
- Proximal convolution; Secretary filtration, tubular secretion
Correct Answer

A. Glomerular filtration; Tubular reabsorption; tubular secretion

Explanation

The correct answer is Glomerular filtration; Tubular reabsorption; tubular secretion. These three processes are the main steps involved in urine production in the kidneys. Glomerular filtration occurs in the glomerulus, where blood is filtered to form a fluid called filtrate. Tubular reabsorption takes place in the renal tubules, where useful substances like water, glucose, and ions are reabsorbed back into the bloodstream. Tubular secretion involves the transfer of waste products, drugs, and excess ions from the bloodstream into the renal tubules to be eliminated in urine.

Rate this question:
24.

25.

What encases the glomerulus? ***
- Proximal convoluted tubule
- Bowman's capsule
- Distal convoluted tubule
- Loop of Henle
Correct Answer

A. Bowman's capsule

Explanation

Bowman's capsule encases the glomerulus. The glomerulus is a network of tiny blood vessels located in the kidney that filters waste products and excess water from the blood. Bowman's capsule surrounds the glomerulus and acts as a protective barrier. It collects the filtered fluid, known as the glomerular filtrate, and transports it to the proximal convoluted tubule for further processing in the kidney. The other options listed, such as the proximal convoluted tubule, distal convoluted tubule, and loop of Henle, are all different parts of the renal tubule system and are involved in the reabsorption and secretion of substances in the urine, but they do not directly encase the glomerulus.

The proximal convoluted tubule reabsorbs approximately how much of the water and solutes?
- 100%
- 99%
- 87%
- 64%
Correct Answer

A. 87%

Explanation

The proximal convoluted tubule is responsible for reabsorbing water and solutes from the filtrate back into the bloodstream. This process is essential for maintaining the body's water and electrolyte balance. The correct answer of 87% indicates that the proximal convoluted tubule reabsorbs a significant amount of water and solutes, but not all of it. This allows for the proper excretion of waste products and helps regulate the concentration of substances in the body.

What does the proximal convoluted tubule resist reabsorbing?***
- Glucose
- Amino acids
- Nitrogeneous waste
Correct Answer

A. Nitrogeneous waste

Explanation

The proximal convoluted tubule in the kidney resists reabsorbing nitrogenous waste. This waste includes substances like urea and creatinine, which are byproducts of protein metabolism. The tubule plays a crucial role in filtering waste products from the blood and excreting them in urine. While it reabsorbs essential substances like glucose and amino acids, it actively resists reabsorbing nitrogenous waste to ensure their elimination from the body. This helps maintain the body's overall nitrogen balance and prevent accumulation of harmful waste products.

Rate this question:
30.

- Sodium ions, water
- Phosphoric waste, water
- Phenalphaline ions, water
Correct Answer

A. Sodium ions, water

Explanation

In the descending limb of the Loop of Henle, sodium ions are actively secreted while water is passively reabsorbed. This means that the body actively transports sodium ions out of the tubule and into the surrounding tissue, while water moves out of the tubule through osmosis. This process helps to concentrate the urine and maintain the body's water balance.

Rate this question:

1
32.

The descending limb of the loop disallows the reabsorption of water. ***
- True

Rate this question:
33.

If sodium concentration is too ________, the bottom of the loop of Henle will selectively reabsorb water causing urine concentration.
- High
- Low
Correct Answer

A. High

Explanation

If the sodium concentration is too high, it means there is an excess of sodium ions in the body. In this case, the bottom of the loop of Henle, which is a part of the kidney responsible for reabsorption of water and electrolytes, will selectively reabsorb water. This reabsorption of water will result in a higher concentration of solutes in the urine, leading to urine concentration.

Rate this question:
34.

What hormone influences the permeability of the tubular cells to water? ***
- Antidiurectic
- Excretory
- Testosterone
- Adrenal
Correct Answer

A. Antidiurectic

Explanation

The hormone that influences the permeability of the tubular cells to water is antidiuretic hormone. This hormone, also known as vasopressin, is released by the pituitary gland and acts on the kidneys to increase water reabsorption. By increasing the permeability of the tubular cells, antidiuretic hormone allows more water to be reabsorbed from the urine back into the bloodstream, resulting in concentrated urine and preventing excessive water loss from the body.

- Distal convoluted tubule
- Excretory function
- Secretory function
- Arterial supply
Correct Answer

A. Excretory function

Explanation

The correct answer is "Excretory function". The collecting tubule is responsible for the final concentration and excretion of urine. It collects urine from the distal convoluted tubules and empties its contents through the tip of a pyramid into the minor calyx. The other options, such as distal convoluted tubule, secretory function, and arterial supply, are not directly related to the emptying of urine and excretion.

Rate this question:
37.

What is arterial supply?
- Paired with the arteries, but any of them will drain the entire kidney if the others are tied off.
- One renal artery, a branch of the aorta, enters the hilum of the kidney between the pelvis, and the renal vein.
- Maintain the internal homeostatic environment of the body by the regulation of the hydrogen ion.
- Regulates electrolyte concentrations, controls blood volume, and regulates blood pressure.
Correct Answer

A. One renal artery, a branch of the aorta, enters the hilum of the kidney between the pelvis, and the renal vein.

Explanation

The arterial supply refers to the blood vessels that deliver oxygenated blood to the kidneys. In this case, the correct answer states that the renal artery, which is a branch of the aorta, enters the hilum of the kidney between the pelvis and the renal vein. This is accurate because the renal artery is responsible for supplying blood to the kidneys, allowing them to filter waste products and maintain the body's internal homeostatic environment.

Rate this question:
38.

Arterial supply divides into anterior and posterior branches.
- True
- False
Correct Answer

A. True

Explanation

The statement is true because the arterial supply of the body does indeed divide into anterior and posterior branches. This division occurs in various regions of the body, such as the brain, where the anterior and posterior cerebral arteries supply blood to different areas. In other regions, such as the upper and lower limbs, the arterial supply also divides into anterior and posterior branches to ensure proper blood flow to different parts of the body. Therefore, the statement is correct.

Rate this question:
39.

What is venous supply?
- Paired with the arteries, but any of them will drain the entire kidney if the others are tied off.
- One renal artery, a branch of the aorta, enters the hilum of the kidney between the pelvis, and the renal vein.
- Maintain the internal homeostatic environment of the body by the regulation of the hydrogen ion.
- Regulates electrolyte concentrations, controls blood volume, and regulates blood pressure.
Correct Answer

A. Paired with the arteries, but any of them will drain the entire kidney if the others are tied off.

Explanation

The venous supply refers to the system of veins that carry deoxygenated blood from the organs and tissues back to the heart. In the context of the given options, the correct answer suggests that the venous supply of the kidney is paired with the arteries. This means that there are corresponding veins for the renal arteries that carry blood away from the kidney. Additionally, it states that any of these veins can drain the entire kidney if the others are tied off, indicating that there is redundancy in the venous drainage system of the kidney.
