Human Physiology: Blood & Circulation (copy)
Key Concepts on Human Physiology: Blood and Circulation
Blood
: A specialized connective tissue composed of plasma and blood cells.
Plasma
: The liquid component of blood, primarily water (90-92%) with dissolved nutrients, hormones, and waste products.
Coronary Circulation
: Supplies blood to heart muscle (myocardium).
Systemic Circulation
: Blood flow from the left ventricle to body tissues.
Pulmonary Circulation
: Blood flow from the right ventricle to the lungs for oxygenation.
Baroreceptors
: Sensory nerve endings that help regulate blood pressure.
Cardiac Cycle
: The sequence of events in one heartbeat, including systole and diastole phases.
Erythropoiesis
: Formation of red blood cells in the bone marrow.
Heart Structure
: Composed of four chambers (two atria and two ventricles) with valves to ensure unidirectional blood flow.
Functions of Blood
Transportation
: Carries oxygen, nutrients, hormones, and waste products.
Regulation
: Helps maintain pH, temperature, and osmotic balance.
Protection
: Immune function through white blood cells (WBCs) and clotting via platelets.
Blood Composition
Red Blood Cells (RBCs)
: Transport oxygen; lack a nucleus in mammals.
White Blood Cells (WBCs)
: Crucial for immune responses; exist in various forms (e.g., neutrophils, lymphocytes).
Platelets
: Cell fragments important for clotting processes.
Maintenance of Blood Pressure
Systolic Pressure
: Pressure during heart contraction.
Diastolic Pressure
: Pressure during heart relaxation.
Regulated by Baroreceptors
: Send signals to the central nervous system to adjust heart rate and blood vessel dilation.
Heart Disease Overview
Types of Heart Disease
: Includes coronary artery disease, heart failure, arrhythmia, heart attacks.
Risk Factors
: High cholesterol, hypertension, smoking, diabetes, obesity, family history.
Symptoms of Heart Attack
: Chest pain, discomfort in other body areas, shortness of breath, nausea.
Treatment Options
Pacemaker
: Device implanted to regulate heartbeat.
Angioplasty
: Procedure to open blocked coronary arteries.
Coronary Bypass Surgery
: Creating a new route for blood to reach the heart muscle when arteries are blocked.
Heart Transplant
: Replacing a damaged heart with a healthy one.
Treatment Considerations
Open Heart Surgery Types
: On-pump, Off-pump, Robot-assisted.
Post-operative care
: Includes monitoring, diet modifications, and gradually increasing physical activity.
Practical Skills
Identifying Blood Cell Types
: Utilize a microscope to view blood slides and distinguish between various blood cells.
