• Describe lymphoid tissue
• Describe the spleen

Lymphatic System Components

• Cardiovascular system component
• Lymph vessels
• Lymph capillaries
• Lymph nodes (glands)
• Lymph fluid
• Lymphatic tissues

Lymph

• The body fluid that flows through lymphatic vessels.
• Clear, colorless and rich in protein.
• Moves from blood capillaries to tissues and back to blood capillaries.
• Excess fluid is drained by lymphatic capillaries and vessels.
• Drains into the thoracic duct (draining 3/4 of the body) and the right lymphatic duct (draining the final 1/4 of the body).
• The thoracic duct opens into the left innominate vein, while the right lymphatic duct opens into the right subclavian vein.

Lymphatic Circulation

• Lymph capillaries collect excess fluid from tissues.
• Passes through lymph nodes.
• Lymph vessels return filtered lymph to the blood.

Lymph Nodes

• Filtering stations along lymphatic vessels.
• Located primarily in the:
  • Axilla (armpit)
  • Groin
  • Neck

Lymphoid Tissues

• Collections of lymphoid tissue besides lymph nodes.
  • Tonsils
  • Adenoids
  • Nodules located in the spleen.
• No lymphatic tissue in:
  • Central nervous system (CSF)
  • Bone marrow
  • Eye

Spleen

• Lymphatic organ.
• Located beneath the left diaphragm, behind the stomach and protected by the 9th, 10th, and 11th ribs.
• Has a diaphramatic surface and a visceral surface related to the stomach, left kidney and pancreas.
• It has two surfaces:
  • Visceral (related to the stomach, pancreas and left kidney)
  • Diaphragmatic (related to the diaphragm)
• The spleen's hilum is present on its visceral surface.

This quiz covers key components and functions of the lymphatic system, including lymph vessels, lymph nodes, and related tissues. It aims to enhance understanding of the circulatory system's relationship with the lymphatic system. Perfect for students studying advanced biological concepts.
