jenyasd209 [6]

Mucous membranes line the passageways that open to the exterior of the body, including those of the respiratory, digestive, reproductive, and urinary systems in the body.

A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue.

It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes, eyelids, ears, inside the nose, inside the mouth, lips, the genital areas, the urethral opening and the anus. Some mucous membranes secrete mucus, a thick protective fluid. The function of the membrane is to stop pathogens and dirt from entering the body and to prevent bodily tissues from becoming dehydrated.

One of its functions is to keep the tissue moist (for example in the respiratory tract, including the mouth and nose).  It also plays a role in absorbing and transforming nutrients.  

Mucous membranes also protect the body from itself. For instance, mucosa in the stomach protects it from stomach acid and mucosa lining the bladder protects the underlying tissue from urine. In the uterus, the mucous membrane is called the endometrium, and it swells each month and is then eliminated during menstruation.

What is not a characteristic of the cortical nephrons?
Pani-rosa [81]

Answer:

Their nephron loop is closely wrapped with vasa recta.

Cortical nephrons are located in the cortex.

They form 85% of all the nephrons in the kidney. They are located mostly within superficial cortex of kidney. The loop of henle of a cortical nephron is relatively short and hence not closely wrapped with vasa recta. Efferent arteriole delivers blood to a network of peritubular capillaries.

Moving the humerus laterally at the shoulder joint is an example of which type of movement
aleksklad [387]
The answer is Abduction. In medicine and biomechanics, movements of limbs and other body parts toward or away from the center line of the body are termed as adduction and abduction respectively. Adduction is the movement of a body part toward the body's midline. Abduction is the movement away from the mid line. For example, abduction of the shoulder raises the arms out to the sides of the body.
