Study Notes
Survival Needs and Body Activities
- Five essential survival needs: communication, intake of oxygen, intake of raw materials and elimination of waste, protection, and body movement
- Corresponding body activities: transport systems, nervous and endocrine systems, ingestion of nutrients, elimination of waste, protection against external environment and microbial infection, and body movement
Communication
- Internal communication: nervous and endocrine systems involved in maintaining homeostasis and regulating vital body functions
- External communication: special senses, verbal and non-verbal activities, and nervous system
Transport Systems
- Blood, circulatory system, and lymphatic system involved in transporting oxygen, nutrients, and waste products
- Heart: a muscular sac that pumps blood throughout the body, maintaining blood pressure, and beats 65-75 times per minute at rest
- Lymphatic system: consists of lymph vessels, lymph nodes, and lymph, which filters out microbes and other materials, and returns to the bloodstream
Internal Communication
- Nervous and endocrine systems involved in maintaining homeostasis and regulating vital body functions
- Pathogenesis: main processes causing illness or disease, including inflammation, tumours, abnormal immune mechanisms, thrombosis, embolism, and infarction
Disease-Associated Terminology
- Acute: disease with sudden onset, often requiring urgent treatment
- Acquired: disorder that develops after birth
- Chronic: long-standing disorder that cannot usually be cured
- Congenital: disorder present at birth
- Sign: abnormality seen or measured by others
- Symptom: abnormality described by the patient
- Syndrome: collection of signs and symptoms that tend to occur together
Atomic Structure and Chemical Bonds
- Atoms consist of protons, neutrons, and electrons
- Electrons in outermost shell are important for chemical reactions
- Isotopes: atoms of an element with different numbers of neutrons in the nucleus, affecting atomic weight
Biological Molecules
- Carbohydrates: composed of carbon, oxygen, and hydrogen, with carbon atoms arranged in a ring
- Glucose: main form of sugar used by cells, can be broken down in the presence or absence of oxygen
- Polysaccharides: complex carbohydrates formed by linking monosaccharides together
- Proteins: composed of amino acids, which contain carbon, hydrogen, oxygen, nitrogen, and sometimes sulphur
- Importance of biological molecules: provide energy, form structures, and act as receptors on cell surfaces
