Gland [glans, an acorn]. 1. An organ which secretes something essential to the system or excretes waste materials the retention of which would be deleterious to the body.

In structure glands may be tubular or racemose, simple or com- pound. 2. The bulbous end of the penis and clitoris. G.s, Absorbent. See G.s, Lymphatic
