Anatomy and Physiology: Digestive and Integumentary Systems

Flashcards covering the digestive system, the integumentary system, and the clinical significance of skin color changes.

What are the primary functions of the digestive system according to the lecture?

It converts food into building blocks for growth, repair, control of the body system, and energy release, while also providing for the removal of wastes.

What are the two natures of digestion?

Digestion is both chemical and mechanical in nature.

How is food mechanically broken down in the body?

The teeth break food into swallowable sizes and the stomach further breaks it down into smaller pieces.

Which organs and glands provide digestive juices to break complex molecules into simpler ones?

The stomach, the liver, and the pancreas.

Where in the digestive system are nutrients taken up into the bloodstream?

Nutrients are taken up as they pass through the small intestines.

Through which structures are waste products excreted?

The rectum and the anus.

Which gland is identified as the largest gland in the body?

The liver.

What are the functions of the salivary glands and the pancreas in the digestive process?

Salivary glands break down food, and the pancreas releases insulin and digestive enzymes.

What is the largest organ of the body?

The skin (integumentary system).

What amount of skin loss is considered potentially fatal for a patient?

A loss of $1/3$ of the patient's skin.

What are the three layers that make up the skin and its underlying tissue?

The epidermis, the dermis, and the subcutaneous tissue.

What are the protective functions of the skin?

It protects against harmful bacteria, temperature extremes, sunlight, and other threats in the environment.

Aside from protection, what are other functions of the skin?

It regulates body temperature, acts as an excretory organ, maintains water balance, serves as a sensory organ, and provides shock absorption.

What conditions might be indicated by red skin color?

Hypertension, stroke, heart attacks, alcohol abuse, sunburn, or carbon monoxide poisoning.

What specific shade of red is associated with carbon monoxide poisoning?

A cherry red color.

What might pale skin indicate in a patient?

Shock, heart attacks, fright, anemia, or fainting.

What conditions are associated with a blue skin color?

Asphyxia, hypoxia, too much carbon dioxide, heart attacks, poisoning, or cold.

What is the definition of asphyxia?

Suffocation.

What is the definition of hypoxia?

A lack of oxygen.

What does a yellow color in the skin and the whites of the eyes indicate?

Liver disease.

What does a black and blue skin color typically signify?

Bruising.

Which other body systems were mentioned at the end of the module?

The muscular system, skeletal system, nervous system, endocrine system, and circulatory system.
