Relationships - Cardiovascular, Lymphatic and Immune system

Question 1

Describe the relationship between the lymphatic and immune system

Answer 1

Because the lymphatic system contains a large no. of lymphocytes (in lymph nodes), whilst also being the site of lymphocyte production and maturation (bone marrow and thymus
Then these lymphocytes can be used by the immune system to detect and destroy invading pathogens. The lymphatic system also collects excess tissue fluid (inflammation) and cell debris for the removal of pathogens.

Question 2

Explain the relationship between the lymphatic and cardiovascular system

Answer 2

Because the lymphatic system collects excess tissue fluid leaked out from plasma in the CV system, and filters it through the thoracic duct, it can then return the filtered fluid back into the CV system, so both systems work together to transport fluid around the body.

Question 3

Explain how the cardiovascular and urinary systems work together to maintain blood pressure in the case of hypertension.

Answer 3

The C.V. system can decrease blood pressure by dilating blood vessels and slowing the heart
beat.

The urinary system effects blood pressure by altering the amount of urine produced (produces more when blood pressure is too high to decrease blood volume).

Question 4

Describe the role of the cardiovascular and integumentary systems in the regulation of high body temp.

Answer 4

The integumentary system regulates body heat by secreting sweat which cools the body down
via evaporative cooling (convection).

It also works with the cardiovascular system to vasodilate
blood vessels in the dermis so that bodily heat can be expelled by radiation, since
blood is to reach closer to the surface, regulating high body temperatures.
