Why do you think it is important for the lymphatic system to be closely related to the blood circulatory system?

Multiple Choice

Which system in the human body has a function closely related to the blood circulatory system?

• Lymphatic system

• Digestive system

• Respiratory system

• Nervous system

Multiple Choice

What is the main function of tissue fluid in the exchange between blood capillaries and body cells?

• To transport oxygen and nutrients to body cells

• To carry hormones to the brain

• To remove all proteins from the blood

• To increase blood pressure in veins

Multiple Choice

"What is formed after blood plasma diffuses into the intercellular space from the blood capillaries?"

• Blood serum
• Lymph fluid
• Cerebrospinal fluid
• Interstitial / Tissue fluid

Multiple Select

Which of the following statements about the formation of tissue fluid are correct?

• Blood plasma diffuses from capillaries to the intercellular space due to high pressure.

• Tissue fluid is formed at the venule end of the capillary.

• Blood plasma that bathes cells is called tissue fluid.

• The pumping force of the heart contributes to tissue fluid formation.

Multiple Select

Tissue fluid does NOT contain _________, _________ or __________ because these are too large to diffuse out of the blood capillaries.

• erythrocytes

• water
• plasma proteins

• platelets

Multiple Choice

At the venule end of the blood capillary, what happens to water, mineral salts, and waste?

• They are reabsorbed into the venule capillary.

• They are lost from the body.

• They remain in the tissue fluid permanently.

• They are converted into oxygen.

Open Ended

Explain what happens to the 15% of fluid that does not diffuse back into the venule end of the blood capillary.

Multiple Choice

What is the smallest vessel in the lymphatic system that collects and returns the excess fluid to the blood circulatory system?

• Lymphatic capillary

• Arteriole

• Venule

• Blood capillary

Multiple Select

The lymph are different compared to the blood because the lymph ............

• has more lipid

• has more oxygen

• has more lymphocytes

• yellowish in colour

• has no plasma proteins, erythrocytes and platelets

Multiple Choice

Which of the following is a similarity between lymph and tissue fluid?

• Both contain plasma without the plasma proteins, erythrocytes and platelets.

• Both have high content of lymphocytes.

• Both have high content of fat and fat-soluble substances.

• Both contain plasma proteins, erythrocytes and platelets.

Multiple Choice

Which of the following statements about lymphatic capillaries is correct?

• They have walls consisting of one layer of cells only.

• Both ends are open to the intercellular space.

• They are identical to blood capillaries in structure.

• They do not merge to form larger vessels.

Multiple Choice

Which of the following mechanisms help in the flow of lymph through the lymphatic system?

• Heartbeat pulse

• Contraction of skeletal muscles

• Peristalsis in the digestive tract

• All of the above

Multiple Select

What are the lymphatic vessels that connect with the subclavian vein (blood circulatory system)?

• Thoracic duct

• Right lymphatic duct

• Bile duct

• Pancreatic duct

Multiple Select

How the lymphatic system complements the blood circulatory system?

• Maintaining fluid balance

• Transporting dietary lipid

• Supporting immune function

• Trigger blood clotting

Multiple Choice

Which of the following is NOT a function of the lymphatic system?

• Returning excess tissue fluid to the blood flow

• Producing and storing lymphocytes for antibody production

• Transporting fat-soluble substances from the intestine
