8dsh

The glomerular capsule is composed of two layers of squamous epithelial cells

True

The efferent arteriole supplies blood to the capillary of the glomerulus

False

Glomerular filtrate has a composition similar to tissue fluid

True

Sympathetic nerve impulses usually cause proportional degrees of vasodilation in the afferent and efferent arterioles

False

If the osmotic pressure of the blood plasma is decreased, the glomerular filtration rate is increased

True

The glomerular filtrate in the proximal convoluted tubule is isotonic to the plasma of the peritubular capillary

True

When the concentration of water in body fluids increases, the secretion of ADH increases

False

Urine is forced along the length of the ureter by peristaltic waves

True

The urinary bladder is located above the parietal peritoneum

False

Active transport mechanisms have limited transport capacities because the renal tubule is not very permeable to the absorption of molecules

False

Large amounts of hydrogen ions are secreted between plasma and urine by the nephron loop

False

An increase in sodium reabsorption increases water reabsorption by actively transporting sodium ions into the blood

False

ADH functions to increase absorption of water from urine into blood by increasing the permeability of the distal convoluted tubules and collecting ducts

True

Inulin clearance measures the rate of glomerular filtration

True

Inulin and para-aminohippuric acid (PAH) can be used to determine glomerular filtration rate and the rate of blood flow through the kidneys

True

The organs of the upper respiratory tract are located outside the thorax

True

The pharynx is an enlargement at the top of the trachea that houses the vocal cords

False

The glottis is the opening between the vocal cord

True

The left lung is larger than the right lung and is divided into three lobes

False

The pectoralis minors and the sternocleidomastoid are useful in aiding forced expiration

False

A sudden contraction of a diaphragm while the glottis is closed produces a sneeze

False

Ordinary air is about 21% oxygen and 78% nitrogen

True

Carbon monoxide bonds to hemoglobin more effectively than does oxygen

True

The greatest amount of carbon dioxide transported in the blood is in the form of dissolved carbon dioxide

False

The inflation reflex is activated when stretch receptors are stimulated during inspiration

True

Oxygen is carried in the blood in the form of bicarbonate ions and is bound to hemoglobin

False

Carbon monoxide is toxic because it attacks and destroys the respiratory center in the brain

False
