39 multiple choice 2 points
which layer of the external kidney is dense fibrous connective tissue for connection of the kidneys and adrenal glands to external organs?
renal fascia
fibrous capsule
perineal fat layer/capsule
visceral peritoneum

40 multiple choice 2 points
which enzyme is found in saliva and begins the digestion of starch?
peptidase
lipase
kinase
salivary amylase

41 multiple choice 2 points
a vascular bed experiences increased metabolic demand. what is the most likely effect on the exchange of oxygen and carbon dioxide between
oxygen uptake will decrease and carbon dioxide diffusion will increase.
oxygen uptake will increase and carbon dioxide diffusion will decrease.
oxygen uptake will increase and carbon dioxide diffusion will increase.
oxygen uptake will decrease and carbon dioxide diffusion will decrease.

Explanation:

Identify the outer connective tissue layer of the kidney

The renal fascia is the outermost layer of dense fibrous connective tissue that anchors the kidney and adrenal gland to surrounding structures and the abdominal wall.

Identify the salivary enzyme that digests starch

Salivary amylase is the enzyme present in saliva that initiates the chemical breakdown of dietary starches into simpler sugars.

Determine the effect of increased metabolic demand on gas exchange

Increased metabolic demand in a tissue bed increases oxygen consumption and carbon dioxide production, which enhances the partial pressure gradients, thereby increasing both oxygen uptake into the tissue and carbon dioxide diffusion out of the tissue.
