1. Human Body Systems
The human body is a complex organism made up of many different systems that work together to maintain homeostasis. These systems can be broadly categorized into two groups: the skeletal system and the muscular system.
The skeletal system provides support and protection for the body, while the muscular system allows for movement. Other major body systems include the circulatory system, respiratory system, digestive system, nervous system, and endocrine system. Each system has its own unique set of organs and tissues that perform specific functions.
For example, the circulatory system is responsible for transporting blood throughout the body, while the respiratory system is responsible for exchanging oxygen and carbon dioxide with the environment.
Organs and Tissues
- Organs are structures that perform a specific function, such as the heart, lungs, or brain.
- Tissues are groups of similar cells that perform a specific function, such as muscle tissue, connective tissue, or nervous tissue.

Detailed FAQs: The Human Body An Orientation Worksheet Answers
What are the major systems of the human body?
The major systems of the human body include the skeletal system, muscular system, nervous system, endocrine system, circulatory system, respiratory system, digestive system, urinary system, and reproductive system.
How many body cavities are there?
There are two main body cavities: the dorsal cavity and the ventral cavity. The dorsal cavity is further divided into the cranial cavity and the spinal cavity. The ventral cavity is further divided into the thoracic cavity, abdominal cavity, and pelvic cavity.
What is the standard anatomical position?
The standard anatomical position is standing upright with the arms at the sides and the palms facing forward.
