Anatomy and Physiology of the Mouth

1. Anatomy and Physiology of the Mouth

The digestive system is a long tube that breaks food down both mechanically and chemically. In this lesson, you will learn about the mouth and how it begins the digestive process - with the help of the teeth and the enzyme called salivary amylase.

Anatomy of the Throat and Esophagus

2. Anatomy of the Throat and Esophagus

After food has been partially broken down in the mouth, it moves through the pharynx, or throat, and the esophagus. In this lesson, you will learn how food is swallowed and how it is propelled by peristalsis through the esophagus.

Anatomy and Physiology of the Stomach and Autonomic Nervous System Controls

3. Anatomy and Physiology of the Stomach and Autonomic Nervous System Controls

In this lesson, you will learn how the unique anatomy of the stomach - including rugae, gastric pits and gastric glands - makes it a perfect organ for digestion. You will also learn how the autonomic nervous system controls digestion.

What is the Small Intestine? - Anatomy and Functions

4. What is the Small Intestine? - Anatomy and Functions

In this lesson, you will learn about the three divisions of the small intestine - the duodenum, jejunum, and ileum. You will also gain an understanding of the basic functions of each of these sections, including their role in removing bacteria.

What Is the Pancreas? - Function, Enzymes & Role in Digestion

5. What Is the Pancreas? - Function, Enzymes & Role in Digestion

Your pancreas plays an important role in the digestion of food. In this lesson, you will learn about the enzymes found in pancreatic juice that allow your body to break down carbohydrates, proteins and fats.

The Gallbladder & Liver: Function & Role in Digestion

6. The Gallbladder & Liver: Function & Role in Digestion

Bile is produced by the liver and stored in the gallbladder. In this lesson, you will learn about bile and its role in the breakdown of dietary fats. You will also learn how the hormones secretin and cholecystokinin help regulate these organs.

Anatomy and Physiology of the Large Intestine

7. Anatomy and Physiology of the Large Intestine

The large intestine is the made up of the cecum, colon, rectum and anal canal. In this lesson, you will learn about the anatomical features and basic functions of these large intestine segments.

Calories: Definition, Purpose & Total Count

8. Calories: Definition, Purpose & Total Count

A calorie is a unit of measurement used to express energy. There are three nutrients that provide the body with calories: carbohydrates, proteins and fats. Learn about these macronutrients and recommendations for total energy intake: EER and AMDRs.

The Importance of Carbohydrates: Functions & Impact of Deficiency

9. The Importance of Carbohydrates: Functions & Impact of Deficiency

The main function of carbohydrates is to provide the body and brain with energy. An adequate intake of carbs also spares proteins and helps with fat metabolism. Learn about the roles carbohydrates play and what happens when you don't get enough of them.

Lipids: Types & Nutritional Role

10. Lipids: Types & Nutritional Role

There are different types of lipids, and each one plays a role in your health. Learn how triglycerides, phospholipids and steroids differ in their chemical structure and the jobs they do within your body.

Primary Functions of Protein in the Body

11. Primary Functions of Protein in the Body

Protein is a vital molecule that carries out many functions in your body. Learn how proteins provide structure, regulate body processes, transport materials throughout your body, help your immune system and act as a source of energy.

Minerals in Our Food: Functions in the Body & Food Sources

12. Minerals in Our Food: Functions in the Body & Food Sources

Minerals are important substances that help your body's form and function on many different levels. This lesson will go over some important ones, what they do, and where they are found in our diets.

Vitamins We Need: Their Importance & Sources

13. Vitamins We Need: Their Importance & Sources

There are a lot of different vitamins, and they come from many different places! This lesson will teach you about what they are, how many different kinds you need, what they do, and where you can obtain them naturally.

Hormones: Definition, Function & Intro to the Endocrine System

14. Hormones: Definition, Function & Intro to the Endocrine System

This lesson introduces the endocrine system and provides a brief overview of each endocrine gland. It also provides the definition of hormones and describes their general function inside the body.

What Is the Pituitary Gland? - Functions, Hormones & Hypothalamus

15. What Is the Pituitary Gland? - Functions, Hormones & Hypothalamus

In this lesson, we'll discuss the functions of the anterior and posterior portions of the pituitary gland, the hormones they release and the relationship with the hypothalamus.

The Thyroid Gland: Functions, Calcitonin & TSH

16. The Thyroid Gland: Functions, Calcitonin & TSH

Your thyroid gland produces the hormones T3 and thyroxine (T4), which play a role in metabolism. Your thyroid also produces calcitonin, which helps regulate blood calcium levels. In this lesson, you will learn about the thyroid gland and its hormones, including how they are regulated by TSH.

Parathyroid Gland: Calcium Metabolism, Osteoclasts & PTH

17. Parathyroid Gland: Calcium Metabolism, Osteoclasts & PTH

The parathyroid glands are tiny endocrine glands found on the posterior surface of the thyroid gland. In this lesson,, you will learn about the parathyroid glands, and the role parathyroid hormone plays in maintaining normal blood calcium levels.

Pancreas: Functions, Anatomy & Insulin Production

18. Pancreas: Functions, Anatomy & Insulin Production

The islets of Langerhans within your pancreas produce the hormones insulin and glucagon. In this lesson, you will learn how these hormones regulate your blood sugar level in opposite ways.

Adrenal Glands: Function, Cortex & Medulla

19. Adrenal Glands: Function, Cortex & Medulla

The adrenal glands sit on top of your kidneys and are comprised of an inner medulla region that is enclosed by the outer adrenal cortex. Both portions of the adrenal gland secrete hormones that regulate body functions and help maintain internal balance.

Hormones of the Testes and Ovaries: Functions & Anatomical Features

20. Hormones of the Testes and Ovaries: Functions & Anatomical Features

The testes and the ovaries secrete steroid hormones that help you grow and develop. In this lesson, we will learn about the female hormones, estrogen and progesterone, and the male hormone, testosterone, and how these hormones influence the development of secondary sex characteristics.
