Study Notes
Cardiovascular System
- The heart is the major organ of the cardiovascular system.
- Blood is pumped to tissues via arteries and returned to the heart via veins.
- Heart rate is measured in beats per minute (bpm).
- Normal heart rate for adults at rest is around 75 bpm.
- Blood pressure is measured in millimeters of mercury (mmHg).
- Normal blood pressure is around 120/80 mmHg.
Respiratory System
- The respiratory system includes the nose, trachea, lungs, and diaphragm.
- The primary function of the respiratory system is gas exchange - inhaling oxygen and exhaling carbon dioxide.
- Respiratory rate is the number of breaths per minute.
- Typical respiratory rate for adults is 12-15 breaths per minute.
- The lungs have sections known as alveoli, where the actual gas exchange occurs.
- The trachea is a tube with C-shaped cartilage which keeps it open.
Urinary System
- The urinary system includes the kidneys, ureters, urinary bladder, and urethra.
- The primary function is blood filtration to produce urine.
- Urine is produced in the kidneys, and filtered elements and waste are removed from the blood.
- The glomerulus is a capillary structure that filters the blood.
- The loop of Henle is involved in water reabsorption.
- Urine passes through the ureter and out of the body via the urethra.
- Filtration rate is expressed as glomerular filtration rate (GFR)
- Normal values for healthy adults range from 100-180 liters of urine/day.
Nervous System
- The nervous system uses neurons to transmit electrical signals.
- Neurons carry nerve impulses from the cell body or soma to other neurons or effectors, like muscles.
- The brain stem is crucial for basic bodily functions.
- Different parts of the brain have specific functions including the cerebrum (higher-level functions).
- The spinal cord is part of the peripheral nervous system (PNS).
Endocrine System
- The endocrine system secretes hormones into the bloodstream.
- Hormones regulate many bodily functions.
- The pituitary gland is often a key gland in hormone regulation.
- Other glands play important roles like the thyroid for metabolic functions and the adrenal glands for stress response.
Digestive System
- The digestive system processes food through mechanical and chemical breakdown.
- The stomach is a major organ involved in food breakdown.
- Enzymes like amylase, lipase help in the chemical digestion of carbohydrates, fats respectively.
- The small intestine absorbs digested nutrients.
- The liver plays a significant role in producing bile, which helps digest fats.
Reproductive System
- The male reproductive system is responsible for producing sperm.
- The female reproductive system is responsible for producing eggs.
- The primary organs are ovaries in females and testes in males.
- The fusion of gametes leads to fertilization, which produces zygotes leading to the development of a new life.
Other
- The three layers of the uterus consists of perimetrium, myometrium and endometrium.
- Epithelial tissues are involved in secretions, absorption and protection.
- The myocardium is the middle layer of the heart wall.
- The term "chyme" refers to food that passes out of the stomach.
- Body cells have 46 chromosomes.
- The term "gastrointestinal" refers to the stomach and intestines.
- The term "tissue" refers to a group of similar cells.
- The circulatory system consists of arteries, veins, capillaries.
