Human Anatomy and Physiology: Body Systems and Homeostasis

What are the primary functions of secretory regulatory hormones?

They regulate growth, reproduction, and metabolism.

What is the role of the fast-acting control system in the body?

It responds to internal and external changes, activating muscles and glands.

What are the functions of the skeletal system?

It protects and supports body organs, provides muscle attachment for movement, serves as a site for blood cell formation, stores minerals, and forms the external body covering.

What is homeostasis?

The maintenance of a stable internal environment, a dynamic state of equilibrium necessary for normal body functioning and sustaining life.

What is a homeostatic imbalance?

A disturbance in homeostasis that can result in disease.

What does the study of anatomy focus on?

The structure and shape of the body and its parts.

What does the study of physiology focus on?

How the body and its parts work or function.

What are the functions of the respiratory system?

It keeps blood supplied with oxygen, removes carbon dioxide, and maintains acid-base balance.

What are the functions of the lymphatic system?

It returns fluids to blood vessels, disposes of debris, and is involved in immunity.

What are the functions of the urinary system?

It eliminates nitrogenous wastes, regulates water and electrolytes, and maintains acid-base balance.

What is the role of the digestive system?

It breaks down food, allows for nutrient absorption into the blood, and eliminates indigestible material.

What materials are transported in the body via the cardiovascular system?

Oxygen, carbon dioxide, nutrients, and wastes.
