Chapter 15: Problem 18

Sudoriferous glands produce _____. a. sweat b. lipids c. sebum d. milk

Short Answer

Expert verified
Sudoriferous glands, also known as sweat glands, produce sweat to help regulate body temperature and remove waste products. The correct answer is option a. sweat. The other options are incorrect because lipids are primarily produced by the liver, sebum is produced by sebaceous glands, and milk is produced by mammary glands.

Step by step solution

01

Understanding Sudoriferous Glands

Sudoriferous glands, also known as sweat glands, are small tubular structures in the skin that produce sweat. Sweat is a fluid that is secreted by the body to help regulate body temperature and remove waste products. There are two types of sudoriferous glands: eccrine glands and apocrine glands. Eccrine glands are found all over the body, while apocrine glands are found mainly in areas with hair follicles, such as the armpits and groin. #Step 2: Identifying the Correct Answer#
02

Identifying the Correct Answer

Now that we know sudoriferous glands are responsible for producing sweat, we can confidently choose the correct answer, which is option a. sweat. #Step 3: Explaining Why Other Options Are Incorrect#
03

Explaining Why Other Options Are Incorrect

- Option b. lipids: Lipids are a type of fat that is present in the body and are primarily produced by the liver, not sweat glands. - Option c. sebum: Sebum is an oily substance produced by the sebaceous glands, which are found in association with hair follicles, not the sweat glands. - Option d. milk: Milk is produced by mammary glands, which are specialized glands located in the breasts, not sweat glands.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Sweat Glands
Sweat glands, scientifically known as sudoriferous glands, are specialized structures in the skin responsible for producing sweat. These glands play an essential role in helping the body regulate temperature by secreting sweat, which cools the body through evaporation. They also assist in eliminating certain waste products through the skin.

Human skin contains millions of sweat glands distributed across nearly every part of the body with the exception of areas such as the lips and parts of the external genitalia.

The function of these glands is crucial, especially in maintaining homeostasis, which is the body's delicate balance of physiological processes.
Eccrine Glands
Eccrine glands are the most common type of sweat gland and are found all over the human body. Unlike other types of glands, these do not associate directly with hair follicles. Instead, they open directly onto the surface of the skin.

These glands primarily help in thermoregulation, which is the process of maintaining the body's core temperature. During this process, eccrine glands produce a watery and slightly salty solution known as sweat.
  • This sweat is composed largely of water, along with some salts and small amounts of waste products like urea.
  • Eccrine glands are also essential for maintaining the skin's hydration and softness.

Understanding their widespread presence and their functionality emphasizes their importance in everyday bodily functions.
Apocrine Glands
Apocrine glands differ significantly from eccrine glands in their location and function. These glands are primarily located in regions of the body with dense concentrations of hair follicles such as the underarms, groin, and around the nipples.

Apocrine glands become active during puberty and are associated with scent production. They release a thicker and more complex form of sweat that contains proteins and lipids.
  • This secretion is initially odorless, but when it comes into contact with bacteria on the skin, it breaks down and produces body odor.
  • Apocrine sweat contains pheromones, which some studies suggest might play a role in social and sexual communication.

Despite having different roles, both apocrine and eccrine glands contribute to the overall process of sweating and the body's ability to interact with its environment.
