Study Notes
Human Body Care Exam Guide
- Gastrointestinal Tract Accessories: Salivary glands, liver (produces bile stored in gallbladder), gallbladder, and pancreas
- Digestive System Movements: Mixing and peristalsis are types of movements in the gastric system.
- Pyloric Sphincter Function: Regulates chyme flow from stomach to small intestine.
- Small Intestine: Location where water, ions, and vitamins are absorbed.
- Cervical/Vaginal Environment for Sperm: Spermicides make the vagina and cervix unsuitable for sperm survival.
- Cholesterol Transport: Lipoproteins (LDL and HDL) transport cholesterol in blood.
- Inspiration Process: Thoracic cage expands due to diaphragm and intercostal muscle contraction, causing negative pressure to draw air into the lungs.
- Nasal Cavity Function: Increases surface area for moistening, warming, and filtering inspired air.
- Voice Production: Larynx contains vocal cords, where sounds are made through mucosal folds.
- Heart Muscle Contraction/Relaxation: Systole/diastole represent cardiac muscle contraction and relaxation.
- Blood Cells (Leukocytes): Have immune reaction against bacteria or viruses.
- Nerve Impulse Transmission: Convey information along neurons.
Neurotransmitters and Substances
- Dopamine Role: Important neurotransmitter for motivation and pleasure.
- Stimulant Effects: Substances like amphetamines and caffeine increase CNS activity.
- Ovulation Prevention: Certain pills prevent follicle development, inhibiting ovulation.
Other Body Systems and Processes
- Parasympathetic Nervous System: Active during digestion.
- Sympathetic Nervous System: Active during stress or physical response to surroundings.
- Physical Dependence: Substance use becomes necessary for maintaining a normal physiological state.
- Psychological Dependence: Desire for substance-induced effects.
- Intrauterine Devices (IUDs): Highly effective contraceptive methods.
- Pepsin: Enzyme in gastric juice that digests proteins.
- Pancreatic Amylase: Enzyme digesting starches.
- Sexually Transmitted Diseases (STDs): Chlamydia and gonorrhea are examples caused by bacteria.
- Blood Vessels (Capillaries): Exchange substances between blood and tissues.
- Arteries: Transport oxygenated blood from heart to body organs.
- Thermoregulation: Body's response to maintain temperature, often employing sweating.
- Respiration (External): Gas exchange between alveoli and blood.
- Respiration (Internal): Gas exchange between blood and body tissues.
- Thyroid Gland Function: Regulates metabolism.
- Essential Fatty Acids (Polyunsaturated Oils): Important for hormone production and cell membranes.
- Complete Proteins: Provide all 20 essential amino acids.
- Incomplete Proteins: Lack one or more essential amino acids.
- Ovarian Cycle Phases: Stages in the reproductive cycle of human females.
- AIDS: Acquired Immunodeficiency Syndrome
- Nerve Pathway: Transmission of nerve impulses when a stimulus occurs.
- Heart Anatomy: Structure of the heart.
