Overview: Blood Vascular System
- Circulatory system is the body system that moves blood and lymph through vessels.
- Blood vascular system is the part of the circulatory system made of the heart, arteries, veins, and capillaries.
- The heart is the muscular pump that pushes blood through the blood vascular system.
- Arteries are vessels that carry blood away from the heart.
- Veins are vessels that return blood toward the heart.
- Capillaries are tiny exchange vessels between arteries and veins.
- Blood vascular transport delivers oxygen and nutrients to tissues.
- Carbon dioxide and waste products are carried away from tissues by the blood vascular system.
- Hormones are signaling molecules carried from their synthesis sites to target cells.
- Target cells are cells that have receptors or response machinery for a specific hormone.
- Heart chambers are the internal spaces that receive or eject blood.
- Four-chambered heart means the heart has two atria and two ventricles.
- Atria are receiving chambers that collect blood entering the heart.
- Ventricles are discharging chambers that pump blood out of the heart.
- Pericardium is the fibroserous sac surrounding the heart.
- Fibroserous sac means a protective covering with fibrous connective tissue and a smooth serous lining.
