recognise impact of health conditions Flashcards
(43 cards)
anatomy
The study of the body structures and the complex interactions between all body systems
physiology
The study determining how body systems work individually and the relationships between the systems as they interact
pathology
The study of abnormalities within the body that cause disease or illness and how the body functions are affected
what are the levels of organisation
atoms molecules organelles cells tissues organs systems organism
what is a cell
- The smallest functional units of the human body
- undifferentiated cells become specialised in their structure and function.
- generate energy
- controls DNA synthesis, regulates metabolic activity, and cell division.
cell membrane
Protects the cell, controls what enters and exits.
nucleus
Contains the cell’s DNA and controls cell activities.
cytoplasm
Jelly-like substance where cell processes occur, maintains structure.
mitochondria
Produce energy for the cell (ATP).
ribosomes
Make proteins
Endoplasmic Reticulum (ER)
Transports materials, smooth ER makes lipids, rough ER makes proteins.
golgi apparatus
Packages and distributes proteins and lipids + produces lysosomes.
lysosomes
Breaks down waste and old cell parts
vacuole
Where waste products are excreted after being dissolved in the cytoplasm.
homeostasis
The body’s ability to maintain a stable, balanced, and relatively constant internal environment to ensure optimal functioning, despite external factors.
what are examples of health status indicators
body temperature, pulse rate, respiration rate, blood pressure, and BGLs.
Cardiovascular system (circulatory system)
Transports blood, nutrients, oxygen, hormones, and waste products throughout the body.
Respiratory system
Responsible for the exchange of gases, primarily O2 and CO2, between the body and the external environment.
Musculoskeletal system
Contains muscles, bones, joints, and associated tissues that allow movement, provide support, and protect the vital organs.
Endocrine system
Network of glands and organs responsible for producing and regulating hormones.
Digestive system (gastrointestinal system)
Responsible for the breakdown of food into nutrients so that they can be absorbed and used by the body.
urinary system
Maintains fluid and electrolyte balance by removing waste products from the body, and regulating blood pressure.
Reproductive system
Responsible for the production of offspring. Is distinct in males and females.
Integumentary system
Body’s first line of defence and largest organ system, including the hair, skin, nails and associated structures.
