Aug 14, 2020 · Human Physiology (physio = “nature”; -logy = “study”) studies the “nature” of the human body, nature in the sense of how structures at different levels work. Physiology focuses on function, or how structures at different levels work. Anatomy and physiology are intimately related. A hand is able to grab things (function) because the ...

To understand the human body it is necessary to know the structure of its parts, what they do, and how they work together. Anatomy is the scientific study of the structure of living things. The study of how the structures function is known as physiology. A major subdivision of anatomy is human anatomy, which focuses on structures of the human body.

Anatomy is the identification and description of the structures of living things. It is a branch of biology and medicine. People who study anatomy study the body, how it is made up, and how it works.
The study of anatomy dates back more than 2,000 years, to the Ancient Greeks. There are three broad areas:
•human anatomy
•animal anatomy — zootomy
•plant anatomy — phytotomy
Human anatomy is the study of the structures of the human body. An understanding of anatomy is key to the practice of medicine and other areas of health.
In medicine, gross, macro, or topographical anatomy refers to the study of the biological structures that the eye can see. In other words, a person does not need a microscope to see these features.
The study of gross anatomy may involve dissection or noninvasive methods. The aim is to collect data about the larger structures of organs and organ systems.
In dissection, a scientist cuts open an organism — a plant or the body of a human or another animal — and examines what they discover inside.
Endoscopy is a tool for diagnosing illness, but it can also play a role in research. It involves a scientist or doctor inserting a long, thin tube with a camera at the end into different parts of the body. By passing it through the mouth or rectum, for example, they can examine the inside of the gastrointestinal tract.
There are also less invasive methods of investigation. For example, to study the blood vessels of living animals or humans, a scientist or doctor may inject an opaque dye, then use imaging technology, such as angiography, to see the vessels that contain the dye. This reveals how the circulatory system is working and whether there are any blockages.
MRI scans, CT scans, PET scans, X-rays, ultrasounds, and other types of imaging can also show what is happening inside a living body.
Microscopic anatomy, also known as histology, is the study of cells and tissues of animals, humans, and plants. These subjects are too small to see without a microscope.
Through microscopic anatomy, people can learn about the structure of cells and how they relate to each other.
For example, if a person has cancer, examining the tissue under the microscope will reveal how the cancerous cells are acting and how they affect healthy tissue.
A researcher may apply histological techniques such as sectioning and staining to tissues and cells. They may then examine them under an electron or light microscope.
Sectioning involves cutting tissue into very thin slices for close examination.
The aim of staining tissues and cells is to add or enhance color. This makes it easier to identify the specific tissues under investigation.
People who work in histology laboratories are called histotechnicans, histotechnologists, or histology technicians. These people prepare the samples for analysis. Histopathologists, also known as pathologists, study and analyze the samples.
The technician will use special skills to process samples of biological tissues. The tissues may come from:
•patients seeking a diagnosis
•suspects in a crime, if it is a forensic lab
•the body of a person who has died
The process involves:
Most people working in healthcare have had training in gross anatomy and histology.
Paramedics, nurses, physical therapists, occupational therapists, medical doctors, prosthetists, and biological scientists all need a knowledge of anatomy.

Jun 12, 2022 · Human Anatomy. This is the branch of anatomy that is most popular throughout the world and for obvious reasons. We as humans are always curious as to how our body works and how it functions. However, before you know how the parts of the body work you need to know the structure or form. This is where human anatomy comes in.
Anatomy is the study of the structure of living things – animal, human, plant – from microscopic cells and molecules to whole organisms as large as whales. Anatomy Is Everywhere Anthropologists study cultures around the world.
Human anatomy studies the way that every part of a human, from molecules to bones, interacts to form a functional whole. Rembrant’s “The Anatomy Lesson of Dr. Nicolaes Tulp”: Human anatomy is the study of the structure of the human body, from the microscopic to the macroscopic. There are two major types of anatomy.

Oct 28, 2024 · anatomy, a field in the biological sciences concerned with the identification and description of the body structures of living things. Gross anatomy involves the study of major body structures by dissection and observation and in its narrowest sense is concerned only with the human body.
