2025年2月10日 · The human body is the physical substance of the human organism. Characteristic of the vertebrate form, the human body has an internal skeleton with a backbone, and, as with the mammalian form, it has hair and mammary glands. Learn more about the composition, form, and physical adaptations of the human body.

Learn the basics of human anatomy, including key anatomical terms, joint classifications, tissue structures, embryology, and imaging techniques.

15 Basic human biology facts 1. The human body has 12 systems. The human body's 12 systems work together to ensure that we stay alive, healthy, and thrive: The cardiovascular (or circulatory) system transports blood, oxygen, and nutrients throughout the body. The digestive system takes in and processes food, and expels waste.

2023年11月3日 · The human body is a biological machine made of body systems; groups of organs that work together to produce and sustain life. Sometimes we get lost while studying about cells and molecules and can’t see the forest for the trees. It can be helpful to step back and look at the bigger anatomical picture.

The human body is a complex, highly organized structure made up of unique cells that work together to accomplish the specific functions necessary for sustaining life.

2022年10月23日 · This chapter begins with an overview of anatomy and physiology and a preview of the body regions and functions. It then covers the characteristics of life and how the body works to maintain stable …

Anatomy is the study of the structure of the body. Often, you may be more interested in functions of the body. Functions include digestion, respiration, circulation, and reproduction. Physiology is the study of the functions of the body. The body is a chemical and physical machine. As such, it is subject to certain laws.

The basic units of structure and function of the human body — as in all living things — are cells. By the time the average person reaches adulthood, their body has an amazing 37 trillion of them! Each cell carries out basic life processes that allow the body to survive.

Anatomy focuses on the physical arrangement of parts in the body, while physiology studies the inner functioning of cells, tissues, and organs. This section will review the body's major systems: the musculoskeletal system, the circulatory system, the nervous system, the digestive system, the respiratory system, and the integumentary system.

Introduce students to the study of the human body. Define and illustrate the anatomical position. Define directional terms and apply directional terms to descriptions of the human body. Define and describe anatomical planes by section. Locate and describe the divisions of major human and the serous membrane covering them.
