    (B) compare and contrast the anatomical structures and describe the functions of the male and female urinary system;

    (C) summarize and illustrate the structures, functions, and types of nephrons;

    (D) examine the methods of fluid balance and homeostasis in the urinary system, including fluid intake and output;

    (E) analyze the composition of urine and the process of urine formation, including filtration, reabsorption, and secretion;

    (F) describe the relationship between the nervous system, renal system, and muscular system before and during micturition; and

    (G) identify and describe common diseases and disorders of the urinary system such as chronic kidney disease, kidney stones, urinary tract infections, and renal cancer.

    (B) compare and contrast the anatomical structure of arteries, arterioles, capillaries, venules, and veins;

    (C) investigate and illustrate how systemic circulation transports blood, gasses, and nutrients from the heart to the internal anatomy of the heart, including tissue layers, chambers, and valves, and external anatomy of the heart, including coronary vessels;

    (D) describe the relationship between blood flow and blood pressure, including systolic and diastolic pressure, pulse pressure, and mean arterial pressure;

    (E) compare and contrast coronary, pulmonary, and systemic circulation, and describe the major vessels of each;

    (F) illustrate how the PQRST waves of an electrocardiogram (EKG) demonstrate the conduction of electricity through the structures of the heart;

    (G) describe the relationship between the cardiovascular system, nervous system, and muscular system in regulating cardiac output; and

    (H) identify and describe common diseases and disorders of the cardiovascular system such as heart disease, myocardial infarction, ischemia, and hypertrophic cardiomyopathy.

  (15) Lymphatic system. The student analyzes the relationships between the anatomical structures and physiological functions of the lymphatic system and understands the immune response. The student is expected to:

    (A) evaluate the interaction of the lymphatic system with other body systems such as the circulatory system;

    (B) describe the structure and function of the lymphatic organs and explain how lymph moves through the body;

    (C) identify and describe the role and function of the immune cells, including T cells and B cells, within the lymphatic system structures;

    (D) identify and determine antigens associated with ABO blood typing, including Rhesus (Rh) factor;

    (E) summarize the ways the body protects and defends against disease, including inflammation, barrier defenses, and active and passive immunity;

    (F) describe the role of antigens and antibodies in the immune response; and

    (G) identify and describe common diseases and disorders associated with the lymphatic and immune systems such as inherited or acquired immunodeficiencies, autoimmune diseases, and lymphomas.

  (16) Digestive system. The student analyzes the relationships between the anatomical structures and physiological functions of the digestive system. The student is expected to:

    (A) examine the anatomical structures and function of the alimentary canal and accessory organs;

    (B) compare and contrast mechanical and chemical digestive processes;

    (C) evaluate the modes by which energy is processed and stored within the body, including ingestion, propulsion, absorption, and elimination; and

    (D) identify and describe common diseases and disorders of the digestive system such as gallstones, Crohn's disease, irritable bowel syndrome, and gastroesophageal reflux disorder.

  (17) Respiratory system. The student analyzes the relationships between the anatomical structures and physiological functions of the respiratory system. The student is expected to:

    (A) identify and sequence the anatomical structures and functions of the respiratory system;

    (B) compare and contrast the functions of upper and lower respiratory tract;

    (C) describe the physiology of respiration, including internal and external respiration and gas exchange;

    (D) describe the relationship between the respiratory and cardiovascular systems during pulmonary circulation;

    (E) investigate factors that affect respiration, including exercise and environmental changes such as altitude; and

    (F) identify and describe common diseases of the respiratory system such as asthma, emphysema, pneumonia, viruses, and allergies.

  (18) Reproductive system. The student analyzes the relationships between the anatomical structures and physiological functions of the reproductive system. The student is expected to:

    (A) explain embryological development of cells, tissues, organs, and systems;

    (B) describe and examine the location, structure, and functions of the internal and external female and male reproductive organs and accessory glands;

    (C) describe and compare the process of oogenesis and spermatogenesis;

    (D) research and discuss the physiological effects of hormones on the stages of the menstrual cycle;

    (E) identify and distinguish the hormones involved in maturation and development throughout the life cycle, including puberty, gestation, and menopause; and

    (F) identify and describe common diseases and disorders of the reproductive system such as sexually transmitted diseases and cancers of the female and male reproductive systems.
