Summary Introduction
To review:
The given blank space in the statement, “Within the lobes of the mammary glands are smaller units called ___________, which contain glandular ___________ that produce milk when a woman is lactating”.
Introduction:
Breasts or mammary glands are highly developed in females to provide nutrition in the form of milk to their growing offspring. The bulk of breast tissue is made up of fatty or adipose tissue. It gives structural integrity and shape to the breasts. The breast tissue is attached to the chest wall with the help of pectoralis major muscle.
