As a subject matter expert in the field of human physiology, I can provide you with a detailed explanation about the types of sweat and the functions of the glands that produce them.
Step 1: English Answer
Sweating is a natural and essential process for the human body, serving as a means of thermoregulation and excretion. There are indeed two primary types of sweat glands in the human body, each with distinct characteristics and functions: eccrine and apocrine glands.
Eccrine Sweat Glands:
Eccrine glands are the most numerous and widespread type of sweat glands, found all over the body, with the highest density on the palms, soles, and forehead. They are responsible for producing a watery type of sweat that is primarily composed of water, salts (sodium chloride, potassium, and calcium), and small amounts of other electrolytes. The primary function of eccrine sweat is to cool the body through the process of evaporation. When the body's internal temperature rises due to exercise, fever, or external heat, eccrine glands are stimulated to produce sweat, which then evaporates from the skin's surface, dissipating heat and thus lowering body temperature.
Apocrine Sweat Glands:
In contrast, apocrine glands are found predominantly in the armpit and genital regions and are also present in the areola of the nipples. These glands become active during puberty and are larger than eccrine glands. Apocrine sweat is more viscous and contains a higher concentration of proteins, lipids, and steroids. Unlike eccrine sweat, apocrine sweat is not primarily used for cooling; instead, it serves other purposes. The secretions from apocrine glands are odorless initially but can develop a characteristic scent when they interact with bacteria on the skin surface. This interaction is what contributes to body odor, as the bacteria break down the components of apocrine sweat, producing volatile organic compounds that are responsible for the smell.
Interaction with Microbes:
The interaction between sweat and skin bacteria is a critical aspect of the function of apocrine sweat. The bacteria on our skin play a significant role in breaking down the components of sweat, particularly apocrine sweat, which can lead to the development of body odor. This process is a natural part of the skin's microbiome and is influenced by various factors, including personal hygiene, diet, and the use of antimicrobial products.
Regulation of Sweat Production:
The production of sweat is regulated by the autonomic nervous system, specifically the sympathetic nervous system. When the body's temperature rises, the hypothalamus, which acts as the body's thermostat, sends signals to the sweat glands to increase sweat production. This process is part of the body's broader response to maintain homeostasis, ensuring that the body's internal temperature remains within a safe and optimal range.
Health Implications:
Sweating is not only a means of temperature regulation but also plays a role in excreting waste products and maintaining the balance of electrolytes in the body. Abnormalities in sweat production or composition can be indicative of various health conditions, such as cystic fibrosis, which affects the consistency of sweat, or hyperhidrosis, which is characterized by excessive sweating.
In summary, the two types of sweat glands in the human body, eccrine and apocrine, serve different purposes and contribute to the body's ability to regulate temperature and maintain overall health. Eccrine sweat glands secrete a watery sweat for cooling, while apocrine sweat glands secrete a more viscous sweat that can develop a characteristic scent after interacting with skin surface microbes.

The eccrine sweat glands secrete watery sweat to cool off the body, while the apocrine sweat glands secrete oily sweat full containing sebum, proteins, lipids, and steroids, each of which develops a characteristic scent after interacting with microbes on the skin surface.
