Practice questions on the lymphatic system and its role in circulation, including pathways and functions. Helps students grasp the relationship between lymph and blood circulation.
The lymphatic system absorbs fats through lacteals present in the small intestine.

Neutrophils are the primary phagocytic cells that engulf pathogens as part of the immune response.

Humans possess a closed circulatory system, in which blood always remains confined within blood vessels. The human heart is four-chambered and exhibits double circulation.

The lymphatic system does not transport respiratory gases. Oxygen and carbon dioxide are transported mainly by red blood cells and plasma.

Neutrophils are the most abundant WBCs, constituting about 60-65% of total WBC count.

Hemoglobin binds with oxygen in the lungs and transports it to body tissues.

Cardiac muscle fibers are uninucleated, unlike skeletal muscle fibers, which are multinucleated.

Anemia is a condition where there is a deficiency of red blood cells or hemoglobin in the blood.

Blood pressure is measured using a sphygmomanometer. Normal BP is 120/80 mmHg, not 150/100 mmHg.

Most WBCs have a shorter lifespan than RBCs, except for some memory lymphocytes that persist for years.

The circulatory system transports hormones but does not synthesize them; hormones are produced by endocrine glands.
