human organism

• Human Anatomy and Physiology is the study of the structure and function of the human body, providing a basis for understanding a disease.
• The human body has many intricate parts with coordinated functions maintained by a complex system of checks and balances, allowing us to detect changes/stimuli, respond to stimuli and perform actions.
• Anatomy is a scientific discipline that investigates the structure of the body, including the structure of body parts, their microscopic organization, and the process by which they develop.
• Systemic Anatomy is the study of the body by systems, including the Cardiovascular System, Nervous System, Skeletal System, and Muscular System.
• Regional Anatomy is the study of the organization of the body by areas, such as the head, abdomen, and arm.
• Surface Anatomy is the study of external features, which serve as landmarks for locating deeper structures without dissection.
• Anatomical Imaging uses technology to create pictures of internal structures, such as x-rays, ultrasound, and mri.
• Physiology deals with the process or functions of living things, emphasizing that structures are dynamic rather than fixed and unchanging.
• Human Physiology is the study of a specific organism, the human.
• Cellular Physiology is the study of the physiology of cells.
• Systemic Physiology is the study of the physiology of the body as a whole.
• Chemical Level involves how atoms (like H and C) interact and combine into molecules.
• Molecules are formed when atoms combine, and their function is related to their structure.
• Organelles are formed when molecules are combined, and they are small structures that make up some cells.
• Cells are the basic structural and functional units of organisms.
• Tissue is a group of similar cells and materials surrounding them, and its functions are determined by the characteristics of cells around it.
• Ventral body cavities provide protection and allow organ movement.
• Serous fluid is a lubrication found between the two serosa membranes.
• The pelvic cavity contains the bladder, rectum, and some reproductive organs.
• The peritoneal cavity surrounds the abdominopelvic cavity.
• The visceral serosa is the layer that covers the organs in the cavity (inner).
• Inflammation of serous membranes can be referred to as "itis" and includes conditions such as pericarditis, pleurisy, and peritonitis.
• The thoracic cavity is surrounded by ribs and muscles of the chest and is further divided into the pleural cavities (lungs), the mediastinum (central portion of cavity), and the pericardial cavity (heart).
• The parietal serosa is the layer of the membrane that lines the walls of the cavity (outer).
• The abdominopelvic cavity lies below the diaphragm and separates the abdominopelvic from the thoracic cavity.
• The abdominal cavity contains the stomach, intestines, spleen, and liver.
• The pericardial cavity surrounds the heart.
• Retroperitoneal organs are found behind the parietal peritoneum and include abdominal organs that lie against the wall having no mesenteries, such as the kidneys, adrenal glands, pancreas, and parts of the intestine.
• The pleural cavity surrounds the lungs.
• Mesentery refers to the parts of the peritoneum that hold the abdominal organs in place and provide a passageway for blood vessels and nerves to organs.
• The serous membranes are a thin double layered membrane that covers the ventral body cavity and outer surface of the organs.
• An organ is composed of two or more tissue types that perform one or more common functions.
• An organ system is a group of organs classified as a unit because of its common function/s, and its coordinated activity is necessary for normal function.
• The heart is posterior to the breastbone.
• The cranial cavity protects the brain.
• The coronal plane divides the head into anterior/posterior sections.
• Body cavities are spaces within the body that help protect, separate, and support internal organs.
• The trunk is divided into the thorax (chest), abdomen, and pelvis.
• Dorsal body cavities cushion and protect the Central Nervous System (CNS).
• Medial refers to toward or at the midline of the body.
