All living things have the following characteristics: 
- Order
- Respond to Stimuli
- Reproduction
- Adaptation
- Growth & Development
- Homeostasis
- Energy Processing
- Evolution

Characteristics of Living Things

The human anatomy is comprised by many body systems, including:
* Nervous system
* Respiratory system
* Circulatory system
* Gastro-Intestinal (digestive) system
* Skeletal system
* Endocrine system
* Reproductive system
* Lymphatic system
* Immune system

Human Anatomy

The study of small organisms ranging from one cell to few cells to no cells at all. It encompasses fields such as virology, bacteriology, protistology, & mycology.

Microbiology

The scientific field of study of nervous system function and development. The human nervous system is comprised of the central (brain and spinal cord) and peripheral  (nerves and ganglia branching from brain and spinal cord) nervous systems. These are referred to as the CNS and PNS, respectively.

Neuroscience (Neurobiology)

The study of biological timing or "clocks" in living organisms.

OpenStax Biology 2nd Edition

Evolutionary Biology studies the processes that produced the diversity of life on earth or study of the phylogenetic history of organisms on earth.

Evolutionary Biology

The molecular structures and processes of cellular life and their roles in the function, reproduction, and development of living organisms.

Molecular and Cellular Biology

The study of the chemistry involved in life processes to explain form and function based on chemical principles.

Biochemistry

Ecology is a scientific discipline that focuses on interactions of living things in relation to their environment, and encourages understanding of the environment as our home.

Ecology

The study of the structure of living organisms.

Anatomy

The study of the use of living organisms to make products.

Biotechnology

Also called plant biology or plant science, this is the study of plants.

Botany (Phytology)

The study of the biology of organisms in oceans.

Marine biology

Phycology (Algology)

The study of functions in living organisms (how the organism works). 

Physiology

Zoology

Includes the interdisciplinary sciences that focuses on the study of health and health care in both practical applications and research. 

Health Sciences

Biology

The scientific field of study of traits and their passage from parents to offspring. Humans inherit 23 chromosomes from the father, and 23 from the mother. These 23 pairs of chromosomes consist of 22 autosomal chromosome pairs and one sex chromosome pair. The physical unit of inheritance is a gene, comprised of DNA (Deoxyribonucleic acid) segments.
