Study Notes
Introduction to Cardiovascular Physiology
- The course covers endocrine physiology and emphasizes attending lectures in person.
- Prerequisites include passing "The Human Body" and "The Building Blocks" exams.
- Lecture slides are available on Moodle one day prior to each lecture.
- The course topics include heart physiology, kidney physiology, digestive tract physiology, and endocrine physiology.
Cardiovascular System Components
- The cardiovascular system is composed of the blood, the heart, and the blood vessels.
Blood
- Blood is composed of plasma and cellular components.
- Plasma is the liquid part of blood and contains proteins, electrolytes, and nutrients.
- The cellular component includes red blood cells, white blood cells, and platelets.
- Blood analysis provides insights into various health parameters, including hemoglobin levels and white blood cell counts.
Heart
- The heart acts as a double pump, circulating blood through the systemic and pulmonary circuits.
- The systemic circulation is a high-pressure circuit, while the pulmonary circulation is a low-pressure circuit.
- The heart is divided into four chambers: two atria and two ventricles.
- Valves between chambers ensure one-directional blood flow.
- Cardiac output is the volume of blood pumped by the heart per minute, approximately five liters per minute.
Blood Vessels
- Blood vessels transport blood throughout the body and are categorized into arteries, arterioles, capillaries, venules, and veins.
- Arteries are large-diameter tubes with low resistance to blood flow.
- Arterioles regulate total peripheral resistance by adjusting their diameter.
- Capillaries facilitate gas exchange between blood and tissues.
- Venules and veins return blood to the heart, characterized by low resistance and high compliance.
Hematopoiesis
- Blood cells are produced in the bone marrow from hematopoietic stem cells (HSCs).
- The bone marrow contains various cell lines originating from HSCs.
- The bone marrow activity reduces with age.
- The spleen and liver can reactivate blood cell production in certain circumstances.
Bone Marrow Transplant
- Bone marrow transplantation is a treatment option for specific blood disorders like leukemia.
- Bone marrow is harvested from a donor and injected into the patient.
- The injected bone marrow stimulates the production of a large number of blood cells.
Bilirubin
- Bilirubin is a byproduct of heme breakdown and is transported by albumin in the blood.
- In the liver, bilirubin is conjugated and excreted in bile.
- In the intestine, bilirubin is transformed into stercobilin and excreted in feces.
- UV light exposure converts bilirubin into lumirubin, which can be excreted in the urine.
Erythrocytes and Oxygen Pressure
- The relationship between low oxygen pressure and the number of red blood cells was established by Paul Bert and Denis Jourdanet.
- In low oxygen environments, the body increases red blood cell production to improve oxygen-carrying capacity.
Altitude Training
- Altitude training increases red blood cell production, enhancing oxygen-carrying capacity and improving athletic performance.
