Mammary gland. Mammary gland, milk-producing gland characteristic of all female mammals and present in a rudimentary and generally nonfunctional form in males. Mammary glands are regulated by the endocrine system and become functional in response to the hormonal changes associated with parturition. 1  In the primitive monotreme mammals (e.g., platypus), milk is expressed directly from the ducts onto the fur, from which the young lap it up.
The Ganges River, also called Ganga, is a river located in northern India that flows toward the border with Bangladesh (map). It is the longest river in India and flows for around 1,569 miles (2,525 km) from the Himalayan Mountains to the Bay of Bengal.s such, the city's culture is also closely tied into the river as it is the most sacred river in Hinduism. Once the Ganges River flows out of India and into Bangladesh its main branch is known as the Padma River. The Padma River is joined downstream by large rivers like the Jamuna and Meghna rivers.
Pollution of the Ganges, the largest river in India, poses significant threats to human health and the larger environment. Severely polluted with human waste and industrial contaminants, the river provides water to about 40% of India's population across 11 states, serving an estimated population of 500 million people or more, more than any other river in the world. Today, Ganges is considered to be the fifth most polluted river in the world. Raghubir Singh has noted that no one in India spoke of the Ganges as polluted until the late 1970s.
