Definitions

Veins: Carry deoxygenated blood back to the heart.
Arteries: Carry oxygenated blood away from the heart.
Capillaries: Facilitate gas exchange, nutrient delivery, and waste removal between blood and tissues.
Tissue: Group of similar cells performing a specific function.
Cell: Basic unit of life, capable of performing all life processes.
Organ: Structure composed of different tissues working together for a complex function.
Organ System: Multiple organs and structures working together for a major vital function, like digestion or reproduction.
Species or Organism: A living thing that can reproduce and respond to its environment.
White Blood Cell: Fights infections and defends against foreign invaders.
Red Blood Cell: Carries oxygen to the body and carbon dioxide away from the body.
Platelets: Blood components involved in blood clotting to prevent bleeding.
Plasma: Liquid component of blood that carries cells and proteins.
Alveoli: Tiny air sacs in the lungs surrounded by capillaries, where gas exchange occurs between air and blood.
Cartilage: Firm, flexible tissue providing structure and cushioning.
Neurons: Nerve cells transmitting signals throughout the body.
Regeneration: Renewal, restoration, and growth of tissues or organs.
Xenotransplantation: Transplanting cells, tissues, or organs from one species to another.
Stem Cell: A cell that can differentiate into specialized cells.
Specialized Tissue: Tissues with a specific function within an organ or system.

Short Answers

Epithelial Tissue: Covers body surfaces and lines organs, providing protection and acting as barriers.
Connective Tissue: Supports, binds, and connects other tissues and organs. Examples include bone, blood, and fat.
Nerve Tissue: Transmits electrical signals, controlling body functions.

Coronary Artery Disease

Symptoms: Tiredness, dizziness, chest pain, or a burning sensation in the arms.
Diagnosis: Angiogram - a special X-ray where fluorescent dye is injected into the bloodstream.
