Compare and contrast the structure and function of the lymphatic and circulatory system. How are they different? How are they similar? Include the general functions of each. Make sure you include the structure of the vessels that carry the fluid in each system and the of the lymphatic fluid and blood.

Answer: All circulatory and lymphatic

systems are vascular networks that

bear fluid connective tissue

The discrepancies will be

addressed in the section below.

Step-by-step explanation:

Circulatory system is a network of blood vessels through which blood is pumped by a rhythmically beating muscular device, called heart.

There is no such pumping device in lymphatic system, there are lymphatic vessels and lymph nodes.

The artery divides into

arterioles and forms a capillary network within tissues,

while the capillaries

rejoin as veins and form a

vein later.

Therefore, circulation in

the cardiovascular system is

possible.

On one side, the lymph capillaries are

closed, i.e. at the point of origin,

but they form larger lymph vessels together.

So the lymph does not

circulate, but only drains into the

veins.

Blood helps in transportation of nutrients, hormones, etc but most importantly it transports respiratory gases: specially oxygen- with the help of hemoglobin present in RBC .

RBCs are not at all present in lymph, but lots of WBCs are present: hence lymph nodes are the areas where WBCs can fight with germs. Fat absorption and transportation is done by lymphatic system .
